Meditate for Melatonin

People who meditate have long known that this practice has positive health benefits that include improved energy and calmness of mind. Research now shows that meditation also increases levels of melatonin, an important hormone that supports the immune system, promotes deep and restful sleep, slows cell damage and aging, improves energy and may even inhibit the growth of cancer cells.

Melatonin is produced by the pineal gland of the brain. The philosopher Rene Descartes called this tiny gland "the seat of the soul". In the Hindu spiritual tradition, meditation techniques are used to direct energy flow through seven energy centers in the body, or chakras, and selectively activate or suppress their associated glands. The pineal gland corresponds to a chakra located at the top of the head and is believed to influence happiness.

The scientific connection between melatonin and meditation was first explored in 1995 by researchers at the University of Massachusetts Medical Center's Stress Reduction and Relaxation Program. Since melatonin is produced mainly at night, overnight urine samples were collected and tested for 6-sulphatoxymelatonin, a melatonin breakdown product considered to be an accurate reflection of blood melatonin levels.

Researchers found that women who meditated had significantly higher levels compared with women who did not.

A recent study published in the journal Biological Psychology confirmed this finding. The researchers found that meditation before bedtime increased melatonin levels for that night. No increases in blood melatonin levels were noted on nights where participants did not meditate. This suggests that regular practice of meditation is necessary.
