Turn Down the Lights for Better Health

After the sun has set, an important hormone that affects sleep may be altered when exposed to bright artificial lighting, which can affect a host of bodily functions. New research links the use of bright light in the evening to an increased risk of Type 2 Diabetes and High Blood Pressure.

The study appears in the March issue of the Journal of Clinical Endocrinology & Metabolism, and asserts that bright artificial light reduces melatonin and can alter the sleep cycle. In turn, this could affect the body’s ability to regulate body temperature, blood pressure, and glucose levels.
