One major thing I have gained from Dr. Wilson’s vast understanding of the role of hypopthalmic - pituitary - and adrenal function (the HPA axis) is that an excellent night’s sleep is very much the result of a balanced HPA axis. If you suffer from a cortisol imbalance, you will not only have energy disturbances, you will have sleep disturbances! Do you have an issue with sleep? Then please read this article. I know it may seem a bit top heavy on the technical side, but if you slowly go through the material it will make a lot of sense. You can gain a great amount of understanding about stress, insomnia and energy by understanding Dr. Wilson’s work. Here is an excellent article from Dr. Wilson regarding sleep and cortisol.

Stress and adrenal function affect sleep, particularly the circadian pattern of cortisol secretion by the adrenal glands. Circulating cortisol normally rises and falls throughout the 24 hour daily cycle, and is typically highest at around 8 AM and lowest between midnight and 4 AM. Both high and low nighttime cortisol levels can interrupt sound sleep. Stress normally causes a surge in adrenal hormones like adrenaline and cortisol that increase alertness, making it more difficult to relax into sound sleep – especially when they remain high or rise and fall irregularly through the night. Frequent or constant stress can chronically elevate these hormone levels, resulting in a hypervigilant state incompatible with restful sleep.
If this is the reason for poor sleep, anything that reduces stress and enhances the ability to handle stress may improve sleep. This can include relaxation, breathing and/or meditation techniques, certain yoga postures, healthy lifestyle changes, and stress-relieving life alterations. Refraining from vigorous exercise in the evening and taking time to consciously relax before going to bed may calm the adrenals and help lower cortisol and adrenaline levels.
When the adrenals fatigue, adrenal hormone levels may become low, leading to another possible source of nighttime sleep disruption – low blood sugar. Cortisol plays an important role in maintaining blood sugar (glucose) levels around the clock. Although blood glucose is normally low by the early morning hours, during adrenal fatigue cortisol levels may not stay sufficient to adequately sustain blood glucose. Low glucose signals an internal alarm (glucose is the main fuel for all cells, including brain cells) that disrupts sleep so the person can wake up and refuel.
Low nighttime blood glucose can also result from inadequate glycogen reserves in the liver. Cortisol causes these reserves to be broken down into glucose that is then available to the cells. When low cortisol and low glycogen reserves coincide, blood glucose will most likely drop, disrupting sleep. Waking between 1 AM and 3 AM may indicate low blood sugar resulting from inadequate glycogen reserves in the liver, low adrenal function and cortisol, or both. This is often the culprit when panic or anxiety attacks, nightmares, or fitful, restless sleep occur between 1 and 4 AM.
If low blood sugar is disrupting sound sleep, supporting healthy adrenal function and dealing with the adrenal fatigue may contribute long term to sound sleep. Also having a healthy snack before bed can help fortify the body’s nighttime energy reserves. The snack should be one or two bites of food that contains protein, unrefined carbohydrate, and high quality fat, such as half a slice of whole grain toast with peanut butter or a slice of cheese on a whole grain cracker. Eating or drinking sugary, refined foods will only aggravate the problem. Sometimes exercising before bed can help, since exercise tends to raise cortisol levels.
Lack of sleep can be a significant body burden that, in itself, can contribute to adrenal fatigue. Every time the wake/sleep cycle is altered, it takes several days to weeks for the body and cortisol levels to adjust. In fact, sleep ranks with diet and regular exercise as an essential component of a healthy life. People on alternating shifts with less than three weeks between shift changes are continually hammering their adrenal glands and may become very susceptible to adrenal fatigue.
Chronic lack of sleep is now regarded as a health hazard and has been associated with several possible health consequences. These include lowered immunity with increased susceptibility to infections, impaired glucose tolerance, low morning cortisol levels, and increased carbohydrate cravings. Lack of sleep can also elevate circulating estrogen levels, upset hormonal balance, and slow healing and prolong the recovery period. These are in addition to the decreased alertness and concentration that most people experience when missing an inordinate amount of sleep.
The consensus from research and clinical observation is that it is necessary to sleep an average of eight hours per day. Some people need even more in the beginning phases of recovery from adrenal fatigue. A saliva cortisol test done at night and compared with daytime levels and with the test standards for those times will
help determine if either high or low cortisol may be interfering with sound sleep. If cortisol is a likely culprit, cortisol levels will be significantly higher or lower than normal for those times.
Yours in health,

People are becoming more aware of the ravages of stress and how it leaks into every corner of their lives. Of course, increased stress means increased
sleep disturbances for many. Less sleep means they experience more stress the day after. This pattern continues in a vicious cycle, making stress and sleep loss in terms of hours and quality intimately interconnected.
If stress has somewhat depleted the adrenal glands, which is often the case, people under stress do not wake feeling rested. Cortisol, an adrenal hormone, is needed to allow that person to wake feeling refreshed and bouncing out of bed in the morning. It is also important to induce an alpha wave, a requirement for the first phase of sleep. If cortisol is low, falling asleep is difficult. Cortisol is also necessary to maintain good blood sugar levels throughout the day and night. If cortisol is low during the day people wake feeling tired and often need coffee, cola and other caffeinated beverages to get going and to keep going during the day. This over consumption of caffeine not only causes blood sugar to rapidly rise and then precipitously fall an hour and a half later, but also tends to interfere with sleep that night. The resulting lack restful sleep creates more stress the next morning and perpetuates the cycle of low cortisol and difficulty sleeping. This low adrenal function is a frequent occurrence in both sleep disturbance and inadequate response to stress. During adrenal fatigue, a condition where the adrenal glands are not able to keep up with the demands placed on them, people often have problems managing their stress and sleeping well.
There can be several reasons for sleeplessness with adrenal fatigue. If you are waking between 1:00 and 3:00 AM, your liver may be lacking the glycogen reserves needed for conversion by the adrenals to keep the blood glucose levels high enough during the night. Blood sugar is normally low during the early morning hours but, if you are experiencing adrenal fatigue, your blood glucose levels may sometimes fall so low that hypoglycemic (low blood sugar) symptoms wake you during the night. This is often the case if you have panic or anxiety attacks, nightmares, or sleep fitfully between 1:00 and 4:00 AM. To help counteract this, have one or two bites of a snack that contains protein, unrefined carbohydrate, and high quality fat before going to bed, such as half a slice of whole grain toast with peanut butter or a slice of cheese on a whole grain cracker.
Both too high and too low nighttime cortisol levels can cause sleep disturbances. To determine if this is a problem for you, simply do a saliva cortisol test at night and compare your night sample levels with your own daytime levels and with the test standards for those times. To do the night test, take a saliva sample at bedtime, another if you wake up during the night and a third when you wake up in the morning. Write the time each sample was taken on the vial and in your notebook on a separate sheet of paper. If cortisol is the culprit, your cortisol levels will be significantly higher or lower than normal for those times. If your nighttime cortisol levels are too low, you may sleep better when you exercise in the evening, before going to bed because exercise tends to raise cortisol levels. If your nighttime cortisol levels are too high, try doing one of the relaxation or meditation exercises to calm you down before going to bed. The specific yoga posture called the alternate leg-pull can be quite helpful in getting to sleep or returning to sleep. This is a basic yoga posture that almost any yoga book or video will describe but an instructor is preferable because there is some subtlety to doing this posture.
Here is a list of some additional things you can do to improve your sleep:
- Above all, go to bed before 10:30 PM and stay in bed until 9:00AM as often as possible, even if it is just on the weekends. It is amazing how restorative sleeping until 9:00 AM is for the adrenals.
- Be sure to get enough physical exercise during the day. Try varying the kinds of exercise you do, their intensity or when you exercise. Many people have told me swimming at night helps them sleep.
- Certain postures in yoga, ta'I chi and qi gong can also be helpful. Check with a teacher of these disciplines to find out which postures or exercises would specifically help you.
- Avoid coffee, caffeine containing beverages and chocolate because they act as stimulants. These can interrupt sleep patterns and increase morning lows. Even if they are consumed early in the day, they can disrupt sleep and make the next morning harder to negotiate.
- Some people are photosensitive and watching television or looking at at computer screen keeps their melatonin from rising and inducing sleep. If you are having difficulty going to sleep and usually are staring at a TV or computer screen late at night, try having an 8:00 PM limit on these visual stimuli.
- If your cortisol levels are low late at night, try exercising in the evening, as exercise raises cortisol levels and may afford you a sound night's sleep.
- There are particular nutritional supplements that can be beneficial. Often melatonin (0.3-1.3 mg) taken 30 minutes before bedtime helps establish normal sleep patterns. Calcium citrate (500mg) taken with 50 mg of 5-hydroxytriptophan (5HTP) at night before retiring is also relaxing and helps many people sleep throughout the night. Trace mineral tablets taken at the evening meal also help relax the body. Adrenal extracts taken ½ hour before bedtime often help those with adrenal fatigue fall asleep and remain asleep. If your adrenal fatigue is moderate or severe, try this one first.
- The hypothalamus is very important in regulating sleep. Although accurately testing hypothalamic function is complicated, a simple test you can do yourself is to try takig one to four tablets of hypothalamus extract and 10-40mg of manganese before bedtime and see if your sleep improves. Sometimes the hypothalamus tablets need to be combined with the adrenal extracts to normalize sleep.
- There are also several herbs commonly used to promote better sleep such as hops (whole plant), catnip (leaves), valerian (root) and licorice (root). Although not known as a sedative, the herb ashwagandha can help indirectly through its ability to normalize cortisol and sex hormones, both of which can produce sleep disturbances.
If none of these help and your life is being deleteriously affected by lack of or interrupted sleep, check your local area for the location of the nearest sleep center. Several cities around the country have these centers that specialize in helping individuals determine the cause of their sleep disturbances.
Take Short Horizontal Rests During the Day
During the day, you will probably notice that you have particular times when you feel more lethargic, cloudy headed, tired or have other symptoms of adrenal fatigue. Try to schedule your breaks so that when these occur, you can physically lie down for 15-30 minutes. Lying down is much more restorative than sitting for the person with adrenal fatigue.
