Sleep deprivation impacts performance even if you don't feel it

Sleep deprivation impacts performance even if you don't feel it

Sleeping for less than six hours was found to hinder the ability of study participants to perform simple tasks, regardless of whether or not they felt rested, due to a lack of focus.

This new study is actually fairly revolutionary when it comes to sleep sciences. The groups were again divided and paired by weekday and weekend sleep habits.

Following on from last year's claims that enjoying a weekend lie-in can make us cleverer and have a positive impact on our waistline, there's now even more reason to stay in bed this Saturday. Researchers say that older people need less sleep and they also sleep more during the week. Scientists have found out that people under the age of 65 who sleep for five or less hours a day are at an increased risk of premature death compared to those who sleep six or seven hours per day.

If you are having trouble sleeping, then this other study suggests that you go camping for a weekend in order to reset your body's natural sleep cycle; or you can simply put on Baa Baa Land, the "world's most boring film".

Golden State Warriors: 3 takeaways from Game 6 vs. Rockets
Houston's Most Valuable Player candidate James Harden dominated early, finishing with 32 points, nine assists and seven rebounds. The Celtics need to defend, then run - they need to force the pace and try to wear down the older Cavaliers.

But the data does not show that short or long sleep is somehow responsible for higher mortality, lead author Torbjorn Akerstedt told the Washington Post.

But when the short sleepers slept in on the weekends, their mortality rate did not differ from that of the consistent seven-hour-a-night-ers.

Interestingly, people who slept too much, regularly hitting the hay for eight hours or longer a night, also had a worse mortality rate. The take home point is that possibly, long weekend sleep may compensate for short weekday sleep.
