Stress Linked with Insomnia - Studies Confirm Natural Sleep Remedies
Sometimes the stresses, pressures and demands at work or at home with family can interfere with our good sleep. Stress manifests on the physical level by an outpouring of the adrenal gland hormones such as cortisol. The adrenal glands are two small triangular-shaped glands that sit on top of each kidney. During times when these stress hormones are increased, they can deplete our calcium levels - a mineral known to help with relaxation and sleep.
Cortisol has a stimulating effect and can promote wakefulness at the very time when one is trying to fall asleep or stay asleep during the night. Scientists have recently discovered that increased blood levels of cortisol exist in people with chronic insomnia.
In one recent study, investigators monitored the sleep of eleven patients with insomnia and thirteen people without sleep disorders (1). Blood was collected every thirty minutes for twenty-four hours, and levels of adrenal stress hormones were monitored. They found that the level of adrenal hormones were significantly higher in the people with insomnia as opposed to the other group. The insomniacs with the highest degree of sleep disturbances produced the highest amounts of cortisol, particularly in the nighttime hours.
Another aspect of this is that it appears people become more sensitive to the stimulating effects of cortisol as they age. Researchers at the Pennsylvania State University College of Medicine (2) found that when both young and middle-aged men were administered a version of cortisol, the middle-aged men remained awake longer and slept less deeply. This finding applies to aging women as well, who tend to experience insomnia and sleeplessness as a significant aspect of their premenopause and menopause symptoms.
From a nutritional perspective, the mineral calcium has long been known as a natural aid to relaxation and sleep and is directly related to our cycles of sleep. In one study, published in the European Neurology Journal, researchers found that calcium levels in the body are higher during some of the deepest levels of sleep, such as the rapid eye movement (REM) phase. The study concluded that disturbances in sleep, especially the absence of REM deep sleep or disturbed REM sleep, are related to a calcium deficiency. Restoration to the normal course of sleep was achieved following the normalization of the blood calcium level.
Research has uncovered that in the presence of elevated cortisol levels, the amount of calcium is rapidly reduced in the body (3). Studies have shown that calcium levels are reduced for as long as the cells are exposed to cortisol, but promptly return to their normal level once the stress hormone is removed. In light of recent discoveries about the relationship between stress hormones and calcium depletion, it's likely that nighttime calcium levels can be restored and insomnia calmed by supplementing with highly absorbable forms of this mineral.
Other helpful tips to support our health in stressful times include eating nourishing foods such as brightly colored vegetables and fruits, taking food supplements like fish oil capsules and green drink powders, doing some daily exercise like taking walks, and creating positive communications and relationships with others.
