Snoozing is normal!

Latest research has shown that man has been progammed to sleep not only at night, but three times during the day.

Midday snooze is a normal event and many people will take two additional short naps around 9 a.m. and 5 p.m. if nothing stands in their way.

These findings, made by sleep researchers at the Max Planck Gesellschafts Institute of Psychiatry in Munich, suggest that the sleep-wake cycle follows an "ultradian" rhythm rather than the conventional circadian or 24-hour pattern.

The discovery that man is biologically programmed to go to sleep during the day came from the study of volunteers who were closed off in underground rooms for three days and nights and had no external clocks to gauge the passage of time.

According to results of the study, published in ‘New Scientist’, most of the volunteers spontaneously took a midday siesta lasting an average of 90 minutes. Some slept for three-and-a-half hours.

In addition, two short naps were observed — one of which came at about 9 a.m. and another at 5 p.m.

They say the newly-discovered sleep pattern may also help in planning astronauts’ periods of work and rest in space missions which have neither days nor nights to keep time by.
