Sleep is tied to every organ system in the body. So if you deprive your body of it, it won’t function properly. It’s not just about the total amount; it’s also about the stages of sleep.
Each of the phases, REM (usually 25 percent of the total night) and NON-REM, need to be present to a certain percent in order to have restful sleep, Dr. Michael Marino, Medical Director of Geisinger Sleep Labs, says.
What people who don’t get enough sleep should do is write down they typical days, Dr. Marino says. That includes work, meals, exercise, and bedtime. “Then we’d look at their sleep hours and see what we can improve,” he adds. “Priorities will have to be set.
The ideal amount of sleep is a range – usually between 6 and 9 hours. Some people feel great after sleeping for 6 hours, other require longer. “But if you sleep 9 hours and still wake up tired, you may require an evaluation,” Dr. Marino says.
There is such thing as “sleeping too much.” If you wake up and feel refreshed, but decide to get another hour of sleep, you trigger another cycle of sleep, Dr. Marino says. “And if you wake up in the middle of it, you break the cycle, which is why you wake up feeling fatigues, even though you slept 10 hours.”
