Why is there the 25 hour sleep cycle built-in in us when the Earths cycle is only 24 hours?
Internal clock runs at above 24 hours due to the fact that we can easily synchronize the day with our body clock by the use of zeitgebers (mostly sunlight). This way the oscillator with a slightly longer period is set to synchrony with the daylight by a minor SCN-mediated reset. This provides for a very stable oscillation. This mechanism goes awry by the use of artificial lighting as well as due to providing us with exciting evening activities such as watching TV, surfing the net, playing computer games, reading, etc. People suffering from DSPS could experiment with light dimmers, toning down their schedule in the evening, properly timed exercise and bright light in the morning. People with ASPS should use opposite measures (e.g.
