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

A recent study by Brigham and Women's Hospital has confirmed that sleep deprivation negatively impacts your work performance even when you do not feel tired

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". Researchers say getting more zzzzz's on Saturday and Sunday morning may extend your life.

Researchers surveyed around 44,000 people in Sweden about their sleep habits, and followed up after 13 years to see who was still alive.

There's no clear-cut answer yet on why sleeping on weekends makes a difference.

However, the effect of short sleeps over a few days may be countered by a later lie-in.

Michael Grandner, director of the Sleep and Health Research Program at the University of Arizona's College of Medicine, who was not involved with this work, warned that sleep is not like a financial transaction.

But channeling your inner cat and sleeping too much can be just as bad for your health, studies have found.

How The Warriors Unleashed Klay Thompson
After being down by 10 at halftime of Game 6, the Warriors trailed by 11 entering the third quarter on Monday night. With the possibility of playing this game without Chris Paul , Harden might need to explode for 40 points or more.

People who got less sleep during the week and slept in on weekends had the same mortality rate as those who get seven hours per night.

Scientists in the Journal of Sleep Research conducted a study on the sleep patterns of adults.

When, instead, different combinations of weekday and weekend sleep durations were analysed, we observed a detrimental association with consistently sleeping ≤5 hr (hazard ratios 1.65; 95% confidence intervals 1.22-2.23) or ≥8 hr (hazard ratios 1.25; 95% confidence intervals 1.05-1.50), compared with consistently sleeping 6-7 hr per day (reference).

Not in the new study. Possibly, long weekend sleep may compensate for short weekday sleep. Monday was found to be the day of the week when people feel the least energetic.

However, people who slept for eight or more hours, seven days a week, were found to have a 25 per cent higher mortality rate compared with those who kept to six or seven hours a day. Torbjörn said it's probably because older people "get the sleep they need". "It's a fuzzy picture that's true", he said.
