circadian rhythm

School systems aren’t built for kids who fall asleep and wake up late, the so-called “night owls”, which may explain why these teens are more prone to depression.

Opponents argue that time change impacts our health, for instance through sleep disturbances.

The researchers go on to argue that modern societies, governed by pre-set schedules, can only seasonally regulate their activities in one-hour increments, as with the current change.

Daylight saving time begins this weekend, meaning clocks will move ahead one hour this Sunday.

The circadian rhythm is the ability of animals to synchronise their physiological processes over a period of about 24 hours.

Bmal1 is also an integral element in the suprachiasmatic nucleus, the master circadian clock found in all mammals that regulates the sleep-wake cycle.
