Sunlight, sexuality and mental health
In the spring a livelier iris changes on the burnish'd dove; In the spring a young man's fancy lightly turns to thoughts of love. Alfred Tennyson. 1884 -------------------------------------------------------------------------------- The association of sunlight and mental and sexual health has long traditions. The summer solstice is historically linked with fertility and sexuality by cultures everywhere. June is the most popular wedding month. There used to be ceremonies symbolic of marriage at midsummer. Traditionally in spring, a young man proposed to a girl requesting she be his wife. Marriages were usually in midsummer. The couple dressed up accompanied by adults and children came to the church. Afterward in most local traditions there was feasting, drinking, and dancing into the evening. They were actually performing a ancient magical rites emphasizing the connection between sexuality and fertility in humans. Numerous studies indicate that fertility and sex drive increase when sunlight is more intense. Testosterone levels in males are higher in the summer. Studies at Boston State Hospital by Dr. Abraham Myerson found that ultraviolet light increased male hormone levels by 120 per cent. Ultraviolet light also increases the level of female hormones. More children are born during the spring and more birth control devices are purchased during the summer months. A further link between sunlight, sex drive and health is the findings that women who have frequent orgasms (with or without a partner) are much more likely to survive breast cancer. Since survival from breast cancer depends largely on whether the cancer has metastasized to other parts of the body, it looks like orgasm somehow prevents metastasis, probably by immune-system stimulation. On the other hand, sex drive wanes in winter. A decrease in female fertility in winter has been documented beginning with North Pole explorer Admiral Byrd's observations a century ago. His expedition reported that Eskimo women lacked menstruation, and thus ovulation, during the periods of 24 hour darkness in their winter. Also in winter, male testosterone levels drop and sperm counts are lower. Infertility is a problem that seems to have increased in recent years. Research on light therapy has suggested that our decreased exposure to natural sunlight reduces fertility. The average office lighting is a much lower intensity than sunlight and lack the full spectrum of sunlight. Light was first used to help infertile couples by Dr. Edmond Dewan at the renowned John Rock Reproductive Clinic in Boston (published in the American Journal of Obstetrics Gynecology, 1967). Couples were given a specially designed light to keep on while they were asleep for three nights a month. The three nights were planned to be the same three days over which ovulation was expected to take place. The couples using the light therapy had a much higher rate of conception than those not using the light. |
