How long do many of the people interviewed sleep every night during the week?

A new study of 1,000 adults conducted by the Better Sleep Committee found that few people understand the important role sleep plays in normal daily brain functions and many people actually reduce their brainpower by getting too little sleep. One in three adults admits that they do not get enough sleep, and lack of sleep is leaving millions of people without the energy to work as hard as they should. Although a large number of people say that they need to be mentally attentive in their work, over half of the people interviewed say that they sleep just under seven hours a night during the week. On the other hand, most of the people interviewed say that they sleep more than seven hours a night at the weekend. This suggests that a large number of people try to catch up on their sleep at the weekend instead of enough sleep during the week, when they most need it.
