Teenagers and Insufficient Sleep: The Obesity risk

Teenagers and Insufficient Sleep: The Obesity risk

Most people understand the causes of obesity as related to overeating. Well that is true. Men and women, boys and girls; all suffer this excessive weight disorder.

At other instances you will often meet in books, e-books and health records that stress is causative to obesity. So you are requested to avoid anything that may cause a build-up of the hormone cortisol, the hormone responsible for the stress response in our bodies. Just for the sake of your own health and for the sake of all those who depend on you.

But, have you ever thought about sleep? What effects it may have on an individual’s weight gain pattern? Yes you know that stress may act either  way; make you lose your appetite and lose weight in the process or increase your appetite to an extent that you eat but do not feel where the food is going, so you eat again…and again. Then you become FAT!

But, what about sleep?

In case you have a child who experience recurrent health related problems or emotional glitches, then you should as well begin considering the possibility of a lack of sleep being involved. Yes there could be other problems involved too, but it would be highly prudent to bring a lack of sleep into the picture

Studies have indicated that each and every function in our bodies is affected by the element of sleep. Imagine that day when you remained up so late and had to wake up so early. How did the day go?

obesity and Insufficient Sleep

Chances are that your day was dragging by. The mood was somber and you did not feel like laughing much. If your job requires it, then you must laugh. Yu must smile, especially when you are a front-line office staff. You do not want to be the cause of really scared customers. You do not want to send them away by a cold face.

The truth is that with insufficient sleep, your mood is highly affected that even though you keep a smile every after a few minutes to keep up with prevailing situations, inside you know just how sickening that faking game is.

In fact most men are not good at this. Women are. So as a man you risk jeopardizing your very job when you miss a sleep.

Focus on teens

You are grown up and you feel that way when you miss your sleep. Now, for a moment try to imagine how the same manifests itself in teenagers. To them, the risks associated with the lack of sleep are far more severe and not just a mere temporary gloom.

Studies in this area have indicated that young persons with sleep problems suffer a lot of medical mal-conditions. They may experience frequent allergies, hearing problems and infections of the ear. And just like you the adult, they too will likely suffer emotional and social problems.

Among these teens, there is a close relationship between sleep loss and diabetes, but most seriously, obesity.

This happens in a number of ways. It can trigger unregulated production of hormones responsible for hunger and appetite. The kids begin to eat without limit and before you know it, their weight explode beyond the accepted limits.

Obesity can also be as a result of irregular behavior of the growth hormone. This hormone is usually produced in high levels during deep sleep. This implies that if the child fails to attain such a level of sleep then chances are that his or her growth may be affected.

The substance responsible for boosting of one’s immunity, interleukin-1, is usually released during sleep. Take away that sleep and you are working against the child’s immunity.  This way chances of them getting depressed or stressed are high. As has been noted before, stress and depression are some of the severe causes of obesity.

Primitive brain prevail under stress-Understanding the Science of Stress

Stress

Stress is a serious impediment in our society it cuts across all sectors of life in humanity

You probably have seen or heard stories of people displaying almost unimaginable mighty strength (superhuman-like powers) when confronted with an emergency situation?

If you haven’t then listen to the story of Lindy shared in class one day: “She raised her hand and told of a time when her mother and sister were out working on their farm. Her mother was driving a big farm machine designed to cut the hay that was growing in their field. She didn’t see the youngster playing in the tall wheat stocks. Accidentally, she ran over her young daughter with this big farm machine. Noticing the unusual sensation as she struck her daughter, she stopped the loud engine and hurried off to see what she had run over. Realizing it was her daughter, she panicked not knowing what to do. There was no one around to help. In a moment of extreme alarm, she lifted the very heavy machine off her daughter and pulled her out with one mighty motion. Once she pulled her child out from underneath the machine, she picked her up, and ran all the way back to the farmhouse to call for help”. Afterwards, the mother collapsed from exhaustion, unable to generate any energy. In those few moments of her daughter’s peril, she had become superwoman.

How can we explain this super-human response that releases power and strength beyond anything we have imagined or previously experienced? What physical and psychological factors are responsible for these amazing abilities?

Primitive brain prevail under stress-The Science of Stress

In the last 50 years we have seen a surge of research on stress. Discovering what actually happens in your body and your mind will help you understand the mechanics behind the stress prevention and management skills you will be learning. This knowledge on the science and theory of stress is captivating and provides strong, credible support for understanding why and how stress management techniques work. Based on this knowledge you will come to understand that you use good stress management skills not just because they feel good, but because they are good science, good medicine.

Why do you feel stress in the first place? What is the purpose of this complex interaction of nerves, muscles, hormones, organs and systems that leads to such unpleasant symptoms as sore muscles, headaches and feelings of emotional upset and a host of other side effects? To answer these questions, we need to go back a few thousand years to see what life was like back then. This will help us understand how our bodies are programmed to respond to threat and danger.

Primitive brain prevail under stress-Stress and the Big Bear

Put yourself in the following imaginary scenario: Imagine that you and I live in a place and time where we find no trace of modern conveniences. We have no comfortable homes, no telephones or television, no indoor plumbing, no electricity, no cars to move us around, none of our modern day comforts. For the sake of this article, let’s say that we live in caves or in huts that are out in the “wilds” of some undeveloped area.

Imagine that I have invited you over to my cave because we just killed some big animal and are having a barbeque. Several of our friends are here outside of my cave just having a pleasant time. I have supplied the group with some croquet mallets and balls and we are playing a little croquet on my front lawn. Like I said, we are having a great time.

We are thoroughly enjoying ourselves when, at some point, we notice some rustling of bushes in the distance and then, charging mightily, or hungrily, toward us emerges a huge ferocious-looking bear. This enormous creature has smelled our picnic and wants some of it for himself. He is a menacing creature that could easily put us out of commission with a single swipe of his mighty forearms.

As you imagine yourself in this scenario, one of the first thoughts that will likely pop into your mind is something like, “Uh-Oh! I am in trouble here!” “I am in danger and I am likely to experience some pain!” These immediate thoughts will be followed closely by the next thought, “RUN!” You sense the immediate need to get away from danger. You don’t want to be its dinner. Your next thought might be, “I need to kill this creature to protect my family, myself, and my friends!” “Fight”

The immediate effect of these thoughts is a physiological response that prepares the body to either run with incredible speed, or fight with incredible strength. This response is known as the fight-or-flight response.

Primitive brain prevail under stress-Fight-or-Flight Response

An exciting flood of physiological processes in the body immediately takes place automatically and precisely after the initial thought of “Uh-Oh!” It is a state of physiological and psychological hyperarousal. A cascade of nervous system firings and release of stress hormones lead to immediate responses that help the person deal with danger either by fighting or running. As you read in Lindy’s story in the opening vignette, the fight-or-flight response can be activated to protect both ourselves and others when we perceive danger.

This response is amazingly complex, involving interactions between many organs and systems in our body. While it is not necessary for you to understand every detail of these complex interactions, it is important to understand the science of what is happening in your body and mind when your stress response is activated. You can use this information to guide you in developing an individualized program to prevent and manage stress.

Primitive brain prevail under stress-The Purpose of the Fight-or-Flight Response

It is interesting that the physiological stress response has only one purpose. The fight-or-flight response is designed to help us do one thing, and only one thing, very well. That one and only purpose of this response is to help us SURVIVE! Our bodies are designed for survival. When the big bear is charging at us, our system knows how to protect us from experiencing pain and death. The mechanics for sustaining us are nearly flawless. There is no other purpose for the fight-or-flight response.

Weight Loss and Adrenal

Weight Loss and Adrenal-Could it be a hindrance?

Andrenal

Is stress causing you to Gain Weight? your adrenal glands initiated a “fight or flight” response

We go through periods of time in our lives when the demands are greater and the stress load is heavier. Regardless of the reasons – illness, relationship difficulties, work struggles, caring for an aging parent or ailing child – there can be a physical impact. We may turn to food for comfort, or we may not nourish ourselves adequately. During times of stress there are actual physiological changes that happen in our bodies, one of which is weight gain. It may not happen overnight, but if we do not pay attention to our body’s needs, over time we may notice we are putting on the pounds.

Our adrenal glands govern our stress response, by secreting hormones relative to our stress levels. They actually help control many hormonal cycles and functions in our body. When the adrenal glands are overworked, the body prepares for disaster, by storing fat and calories. We crave foods, we lose precious energy, and we gain weight. So how can we keep the heavier stress load from equaling heavier bodies?

Weight Loss and Adrenal-How stress becomes physical

For millions of years, humans were forced to protect themselves from environmental factors. From the earliest days of dinosaurs and cavemen, nature has proven its ability to put fear in human beings. Life and death circumstances have evolved around the ability to understand danger, and seek protection and survival. If you were being chased by a predator, your adrenal glands initiated a “fight or flight” response, releasing adrenaline and cortisol into the body. These hormones provided extra physical energy and strength from stored carbohydrates and fats.

While most of our stressors are not the same our earliest ancestors, the body’s natural course of evolution has maintained this original fight-or-flight stress response. But whether we are being physically threatened or not, with any increased stress our body looks to its stored fuel, and then replenishes it when used. Also, with increased levels of cortisol, our body also does not respond as well to leptin, the hormone that makes us feel full, so we eat more.

Modern-day stress may be more psychological than physiological, but it is also more constant. Many of us face chronic stress as a way of life, which means we have consistently elevated levels of cortisol. Now the body thinks it continually needs extra fuel, and typically stores that as fat around the abdomen, or as it’s commonly referred to, the old “spare tire.”

Belly fat: a common sign of adrenal fatigue

Adrenal imbalance causes a number of issues, including an expanded waistline. The science behind it is quite interesting. Normally when we feel begin to feel hungry, our blood sugar drops and the brain sends a message to the adrenal glands to release cortisol. Cortisol activates glucose, fats, and amino acids to keep our body fueled with energy until we eat. Cortisol maintains blood sugar levels, and insulin helps our cells absorb glucose. When we have long term stress, both insulin and cortisol remain elevated in the blood, and the extra glucose is stored as fat mostly in the abdomen.

Here’s where it gets interesting. Scientists have discovered that fat cells actually have special receptors for the stress hormone cortisol, and there are more of these receptors in our abdominal fat cells than anywhere else in our bodies! In addition, scientists have shown that belly fat is actually an active tissue, acting as an endocrine organ that responds to the stress response by actually welcoming more fat to be deposited! This is an ongoing cycle until we take steps to correct this adrenal imbalance. How do we do that?

Weight Loss and Adrenal-Eat well for healthy adrenal glands

What you eat matters. Although it sounds ironic, if you want your body to believe that it is not in danger of starving to death, you need to eat healthy food at regular intervals. Since cortisol helps regulate blood sugar, keeping glucose levels balanced will take some of the stress off the adrenal glands. Three nutritious meals and two healthy snacks spread out across the day will keep our adrenal glands steady.

When you eat matters. Our natural circadian rhythms can help us know when our bodies need nourishment and fuel. Cortisol’s cycle complements our body’s own rhythms, although is highest in the morning and declines gradually throughout the day. When we eat we elevate our cortisol, so it’s ideal to consume larger meals earlier in the day, which also helps our body prepare itself for restful sleep at night.

Have healthy foods on hand. It may be easy to reach for sweets and caffeine for quick energy, but these actually backfire on us, dropping our blood sugar levels rapidly. Reaching for micronutrient-rich foods, such as lean protein, avocado, fresh fruits and vegetable, garlic, and ginger will more adequately support adrenal functioning.

Supplement your daily diet. Adrenal expert, Shawn Talbot, PhD, says, “When it comes to dietary supplementation for stress adaptation and cortisol control, the first line of defense appears in the form of a comprehensive multivitamin/mineral supplement.” The benefits of a daily multivitamin enhance many of the functions in our body. Consider the high-quality multivitamin mineral complex we have in our Program at Women to Women.

For more information on healthy eating and adrenal glands, see my articles about how to eat for your adrenal health.

Weight Loss and Adrenal-Pace yourself to heal

Our fast-paced world is never unplugged. We rarely have time to disconnect from technology, our cell phones, the Internet, email, and even television. And our adrenal glands notice! Instead of being tired, wired, and overeating, consider slowing down and restoring balance to your adrenal glands, and your life. You may think that by moving fast you will lose weight, but in fact, when stress levels are high and our adrenals are working overtime, we will stay in a perpetuating cycle of adding pounds. Here’s how we can learn to pace ourselves.

Sleep

Many of my patients complain of being tired all day then having trouble sleeping at night. They are in an upside down circadian rhythm, which affects cortisol levels, causing irregular sleep patterns. You can correct these by eating less food late in the day, turning off all technology including television, by 8 p.m., and by trying to be in bed and asleep by 10 p.m. The goal is to have at least eight hours of sleep, so our bodies can rest and regulate our hormonal cycles.

Exercise

Our adrenals respond to stress, even if we think it is positive. Exercise is positive, and can help us reduce stress, but only if it does not make us feel tired. When we are exhausted, our adrenals are already working hard, and exercise can put added strain on them. The goal is to keep your heart rate under 90 beats per minute when working out. If you don’t regularly exercise, walking 15 minutes once or twice a day after meals, outside in fresh air, makes our adrenal glands, and our mind and body, very happy.

Have fun

Don’t forget that having fun, laughing, and enjoying your time is a very important way to relax! We all need to make having fun a priority, the benefits are amazing!

Don’t forget to breathe

Deep breaths in and out of your nose can not only slow your heart rate down, but will calm your entire body. Sometimes when we are under stress our breathing becomes shallow, and fast. It only takes three or four deep breaths to feel better. Try to remember that slowing down our breath, as well as our life, even for a few minutes, can make a big difference in reducing our stress level.

Weight Loss and Adrenal-Just let it all go

It isn’t always easy to let things go. We put pressure on ourselves to meet the demands in our lives, to take care of others, to do well in our endeavors, and to make everyone around us happy. But when we forget about ourselves in that equation, the stress will appear as extra pounds, or other things that impede our health and our functioning. When we live with continually elevated levels of stress, our body adjusts to the “crisis mode” and sometimes needs help learning how to live in a calmer state. The first step is to heal your adrenals. By following some of the tips in this article, giving yourself time, and being patient, you will begin to replenish your energy, lose extra weight, and most importantly, feel better.

Stress Slow Killer is Serious Business

Stress Slow Killer

Dr. Dalal Akoury

 

Stress Slow Killer is Serious Business

Stress Slow Killer affects us physically and emotionally. The stress response is mediated through HPA axis and activation of the autonomic nervous system. The aim is to mobilize energy for the “fight or flight” response. This brings about changes in almost all organs and tissues as a whole. In an acute event, after the stressor disappears, the homeostasis or internal equilibrium is regained. In case where the stress continues it leads to chronic disorders involving many organs and this also depends on the nature of stress.

The effects of Stress Slow Killer on each organ

Stress Slow Killer and the Nervous System:

Stress leads to activation of HPA axis once the hypothalamus receives signals from cerebral cortex which are perceived as stress. Then hypothalamus releases corticotropin releasing hormone which stimulates the anterior pituitary to produce adrenocorticotropic hormone (ACTH). ACTH is secreted into the systemic circulation and stimulates the adrenal glands to produce stress hormone called cortisol.

There is stimulation of autonomic nervous system which is caused by direct stimulation of both sympathetic and parasympathetic systems. This is done by hypothalamus. The sympathetic activation leads to release of adrenaline and noradrenaline by the adrenal medulla. These hormones increase the heart rate, raise blood pressure, increase glucose levels in the blood and suppress digestive and reproductive functions. This stimulation is more obvious when the stressor is strong like acute pain. In people with chronic pain, this effect is weak and not clinically obvious unless there is aggravation of symptoms. After the stressor disappears, the parasympathetic nervous system helps in reverting back to normal and regain of internal equilibrium. The autonomic nervous system also interacts with the enteric nervous system and has anti-inflammatory properties.

Stress Slow Killer and the Musculoskeletal system

Due to the effect of stress, the muscle tone increases as the body is prepared for the “fight or flight” response. It results in tension headache and back pain.

 Stress Slow KillerStress Slow Killer and the Respiratory system

Stress increases respiratory rate to increase the availability of oxygen to all organs and muscles so as to prepare for the stress response. This occurs due to direct stimulation of the respiratory center. An excessive stimulation may bring panic attack in some individuals.

Stress Slow Killer and the Cardiovascular system

Acute stress causes activation of the cardiovascular system. This occurs mainly due to release of noradrenaline and adrenaline from the adrenal medulla. These hormones act on the heart to produce the effects which include rapid heart rate, stronger contractions of heart and palpitations. The blood flow to the skeletal muscles and heart increases due to dilatation of blood vessels. These changes occur with acute stress.

Chronic stress is associated with inflammation of arteries of heart (coronary arteries) and may lead to heart attack. There is also higher incidence of hypertension, stroke and atherosclerosis.

Stress Slow Killer and the Endocrine system

Stress related ACTH stimulation results in enlargement of adrenal glands which are required to produce increased amounts of stress hormones. The adrenal cortex produces cortisol and adrenal medulla secretes noradrenaline and adrenaline. These three adrenal hormones play a crucial role in the stress response.

Stress Slow Killer and the Gastrointestinal system

Stress promotes increased consumption of palatable food. Severe stress is associated with nausea and vomiting. It may result in reflux esophagitis. Under the effects of cortisol and adrenaline, liver produces more glucose which is used for energy production by various organs and skeletal muscles. Stress affects digestion adversely and may modulate gut motility to produce diarrhea or constipation.

 

Stress Slow KillerStress Slow Killer and the Reproductive system

The stress response leads to suppression of reproductive function. Chronic stress impairs testosterone secretion in the testes. The sperm production is reduced and infertility may occur. In women, the menstrual cycles become irregular and painful or may develop complete amenorrhea. The sexual desire is reduced significantly.

Stress Slow Killer and the Immune system

Stress leads to suppression of immunity so as to conserve energy. In case of chronic stress, this increases the risk of infections due to poor immunity.

Stress Slow Killer and the Cellular and molecular effects of stress

Stress increases intracellular calcium. This effect is seen in association with message induced stress which stimulates the mast cells to release histamine which causes local vasodilatation and improves perfusion.

On exposure to stress, the cells generate heat shock proteins which promote cell survival. Exposure of cells to temperature of 3 to 5 °C above normal, reactive oxygen species causes induction of heat shock proteins 27 and 70. These proteins inhibit apoptosis and promote survival.

Apoptosis or programmed cell death occurs if a cell is partially damages due to stress or fails to sustain stress. During this process, special enzymes called caspases are activated which bring about protein changes resulting in cell death.

Autophagy is characterised by self-destruction of cell organelles like mitochondria and cytoplasmic proteins. Autophagy is observed in cells exposed to stressors like starvation, ischemia reperfusion injury, increased intracellular calcium and endoplasmic reticulum stress.

So Stress Slow Killer affects each system in the body, each organ and each cell.

Do You Really KNOW Stress Management!?

Stress Management

Dr. Dalal Akoury

Do You Really KNOW Stress Management!?

Your body is hard-wired to react to stress in ways meant to protect you against threats from predators and other aggressors. Such threats are rare today, but that doesn’t mean that life is free of stress.

Stress Management

Stress Management

On the contrary, you undoubtedly face multiple demands each day, such as shouldering a huge workload, making ends meet, taking care of your family, or just making it through the morning rush hour. Your body treats these so-called minor hassles as threats. As a result you may feel as if you’re constantly under assault. But you can fight back. You don’t have to let stress control your life.

Stress Management: Fight or Flight

If your mind and body are constantly on edge because of excessive stress in your life, you may face serious health problems. That’s because your body’s “fight-or-flight reaction” — its natural alarm system — is constantly on.

When you encounter perceived threats — a large dog barks at you during your morning walk, for instance — your hypothalamus, a tiny region at the base of your brain, sets off an alarm system in your body. Through a combination of nerve and hormonal signals, this system prompts your adrenal glands, located atop your kidneys, to release a surge of hormones, including adrenaline and cortisol.

Adrenaline increases your heart rate, elevates your blood pressure and boosts energy supplies. Cortisol, the primary stress hormone, increases sugars (glucose) in the bloodstream, enhances your brain’s use of glucose and increases the availability of substances that repair tissues.

Cortisol also curbs functions that would be nonessential or detrimental in a fight-or-flight situation. It alters immune system responses and suppresses the digestive system, the reproductive system and growth processes. This complex natural alarm system also communicates with regions of your brain that control mood, motivation and fear.

Stress Management means Take Control

The body’s stress-response system is usually self-regulating. It decreases hormone levels and enables your body to return to normal once a perceived threat has passed. As adrenaline and cortisol levels drop, your heart rate and blood pressure return to baseline levels, and other systems resume their regular activities.

But when the stressors of your life are always present, leaving you constantly feeling stressed, tense, and nervous or on edge, that fight-or-flight reaction stays turned on. The less control you have over potentially stress-inducing events and the more uncertainty they create, the more likely you are to feel stressed. Even the typical day-to-day demands of living can contribute to your body’s stress response.

The long-term activation of the stress-response system — and the subsequent overexposure to cortisol and other stress hormones — can disrupt almost all your body’s processes. This puts you at increased risk of numerous health problems, including:

  •                Heart disease
  •                Sleep problems
  •                Digestive problems
  •                Depression
  •                Obesity
  •                Memory impairment
  •                Worsening of skin conditions, such as eczema

That’s why it’s so important to learn healthy ways to cope with the stressors in your life.

Stress Management means identify your Unique Stressors

Your reaction to a potentially stressful event is different from anyone else’s. How you react to stressors in your life includes such factors as:

  •                Genetics. The genes that control the stress response keep most people on a fairly even keel, only occasionally priming the body for fight or flight. Overactive or underactive stress responses may stem from slight differences in these genes.
  •                Life experiences. Strong stress reactions sometimes can be traced to early environmental factors. People who were exposed to extremely stressful events as children, such as neglect or abuse, tend to be particularly vulnerable to stress as adults.

You may have some friends who seem laid-back about almost everything and others who react strongly at the slightest stress. Most reactions to life stressors fall somewhere between those extremes.

Stress Management teach how to React to Life Stressors 

Stressful events are a fact of life. And you may not be able to change your current situation. But you can take steps to manage the impact these events have on you. You can learn to identify what stresses you out, how to take control of some stress-inducing circumstances, and how to take care of yourself physically and emotionally in the face of stressful situations.

Stress Management: Means Move that Body and Exercise!

Stress Management

Stress Management

Any activity that raises your heart rate and makes you sweat will greatly lighten your mood, increase energy, sharpen focus, and relax both the mind and body. For maximum stress relief, try to get at least 30 minutes of activity on most days.

Eat right

Low blood sugar can make you feel anxious and irritable, while eating too much can make you lethargic. Eat small, but frequent meals throughout the day to maintain an even level of blood sugar and avoid these swings in mood.

Get enough sleep

Not only can stress and worry cause insomnia, but also a lack of sleep can leave you vulnerable to even more stress. When you’re well rested, it’s much easier to keep your emotional balance.

When job and workplace stress threatens to overwhelm you, there are simple steps you can take to regain control over yourself and the situation. Your coworkers will love your self-control and may try to adopt your habits, too.

 

 

Stress management strategies include:

  •                Eating a healthy diet and getting regular exercise and plenty of sleep
  •                Practicing relaxation techniques
  •                Fostering healthy friendships
  •                Having a sense of humor
  •                Seeking professional counseling when needed

The payoff of managing stress is peace of mind and — perhaps — a longer, healthier life.
