Get enough sleep, and go to bed before midnight

Millions of people throughout the world do not get enough rest and sleep. In fact, they falsely believe that rest and sleep are a waste of time and energy. This is the opposite of the truth and may be the most ignored cause of disease next to bad nutrition. Prolonged fatigue contributes to nutritional imbalances that may not be so easily undone by just sleeping.
Resting is not just about physical and emotional processing. An area that is not often discussed is spiritual development. By this I mean a specific progression of development of the subtle human bodies, such as the etheric body or etheric double, as it is sometimes called.

Cultivate the habit of going to bed early, before 10 PM. When dark falls, the body naturally wants to sleep. Overriding this desire for sleep interferes with the natural rhythm of cleansing. According to traditional Chinese and Ayurvedic medicine, as well as Western naturopathic healing philosophy, the most important hours for detoxification and rejuvenation are before midnight.

Failure to respond naturally to your body’s circadian rhythms -- sometimes unavoidable because of night shift work or international jet travel -- can have negative health consequences, according to a study published in the May 2008 issue of the “Journal of Circadian Rhythms.”

Researchers from the Misao Health Clinic in Gifu, Japan, conducted a long-term study of the sleep habits of 251 healthy male workers, all under age 61. They researchers found that men who consistently went to bed before midnight had healthier coronary arteries than night owls who didn’t go to bed until midnight or later. These findings held true regardless of the total number of hours the men slept.

This thing will disorganize the exile of useless substances from our body. Our ability to sustain exertion is as vital to our health as what we eat and drink.
That’s why the research also shows that every hour of sleep we get before midnight is twice as beneficial as the hours after midnight.

(25) Metabolic syndrome is not only the precursor to diabetes, but also to high blood pressure, cardiovascular disease, and other life-threatening diseases. Sleep is a valuable means to combat these problems as well.

A healthy body produces special “sleep hormones” that induce sleep in order to repair, rejuvenate and detoxify. These hormones - tryptophan, seratonin and melatonin - calm the nerves, boost immunity, deepen sleep and promote longevity. A shortage of them leads to irregular sleep patterns, restless sleep, weakened immunity and cravings for caffeine, sugar and refined carbohydrates.
