Too Much Sleep

A new study finds that adults sleep more than 7 1/2 hours a day may also be at higher risk. After surveying the health and sleep habits of more than 1 lakh people for an average of almost 10 years, Japanese researchers concluded that the lowest mortality risk occurred in people who slept 7 hours a day.

The study, lead by Dr. Akiko Tamakoshi of the Nagoya University Graduate School of Medicine, appears in the current issue of the Journal's Sleep.

In an accompanying editorial, Dr. Daniel F. Kripke, a sleep expert at the University of California, San Diego said that, 'Although these conclusions might surprise clinicians', they were in keeping with earlier studies.

The study found that people who reported sleeping 8 hours a night had a higher mortality than those who reported sleeping 7 hours. The longer the subjects, the higher the risk. Indeed, Dr. Kripke wrote, 'People who said they slept more than 7 1/2 hours appeared to suffer worse health effects than those who said they slept for 6 1/2 hours.

People who reported sleeping less than 4 1/2 hours had big increases in their mortality risks.
