JessiccaFact: Biological Clock
October 13th 2006 08:34
In 1994, researchers at Northwestern University announced the discovery of the so-called biological clock. It is purported to be a gene that governs the daily cycle of waking and sleeping called the circadian rhythm.
Circadian rhythms are patterns seen in virtually all animals and plants. These rhythms are controlled by biological clocks - which are not perfect timekeepers. When there is an absence of external clues, as is the case in long airplane flights that cause jet lag - the rhythms tend to get off course and need to be reset.
Light seems to be the key to reset many biological clocks - specifically, blue light. That is why jet lag can be helped by exposure to sunlight.
