Dim Light Helps Insomniacs in Getting Sleep
According to a recent research, insomniacs can get proper sleep if they dim the lights a few hours before going to bed. Sleep is controlled by a hormone called melatonin which is secreted by the pineal gland in the brain. Besides this, melatonin also controls blood pressure and body temperature.

The findings were based on a study conducted on 116 healthy participants. The respondents belonged to the age group 18-30. In the study, the respondents were exposed to either bright room light or dim light for eight hours before going to bed.

In order to check the level of melatonin, their blood plasma was collected after every 30 to 60 minutes.

Researchers reveal that exposure to artificial lighting in the normal hours of sleep reduces the level of melatonin by 50%.This can also cause a significant increase in the risk of high blood pressure and diabetes.

The study will be published in the March issue of the Journal of Clinical Endocrinology & Metabolism.

In a news release from the Endocrine Society, study author Joshua Gooley, from the Brigham and Women's Hospital and Harvard Medical School in Boston disclosed that the findings can be significant for the shift workers. These workers are exposed to indoor light at night for a considerable time.
