Should you catch up on sleep?

Sleeping in on the weekends may feel luxurious, but it’s not actually doing your brain any favours, a small new study suggests.

“The usual practice of extending sleep during the weekend is not adequate in reversing the cumulative effects on cognitive function resulting from mild sleep deprivation,” Dr. Alexandros Vgontzas, M.D., director of the Sleep Research.

Lost sleep due to late nights, early mornings or a combination thereof is often called “SLEEP DEBT” and yes, it accumulates, Scientific American reported. The magazine noted that sleep debt can’t be repaid in just one weekend — it takes time for your body to readjust to getting ample rest — but it can be repaid with concerted, consistent effort.
