Light dawns on the body clock

Waterhouse, James
October 1991
New Scientist;10/26/91, Vol. 132 Issue 1792, p30
Discusses the results of a study conducted by biologists at Harvard University which used an artificial light to reset the body clock. Effect of light on biological rhythms on a day-to-day basis; Possibility of using light as a therapy for seasonal depression and jet lag; Factors influencing the circadian clock; Role of the circadian clock in telling the body to step up heat loss and reduce heat production.

    The article presents information on seasonal affective disorder (SAD). Exposure to too little sunlight during darker months may upset the circadian rhythm of the body, which can lead to an imbalance of mood-monitoring brain chemicals. The symptoms of SAD vary from person to person, but some of...

    Travel fatigue is associated with long haul flights, and jet lag is experienced when flights entail transmeridian travel. Symptoms are linked with disturbance of the body's circadian rhythms. Exercise performance may be affected until the body clock is adjusted to the new time zone. Methods of...

    Background: Rapid displacement across multiple time zones results in a conflict between the new cycle of light and dark and the previously entrained program of the internal circadian clock, a phenomenon known as jet lag. In humans, jet lag is often characterized by malaise, appetite loss,...

    This article focuses on a new study related to seasonal affective disorder (SAD). Most SAD sufferers become depressed because the later rising of the sun delays their circadian rhythms relative to clock time. This skews the timing of the release of melatonin, a body-clock hormone triggered by...
