Normal sleep of about 7 – 8 hours a day is healthy.
It stabilizes your waking brain, makes you more alert, and allows you to process information faster
Centers for Disease Control and Prevention Survey done in United States revealed that average nightly sleep time during the workweek is down nearly 20 minutes in the last decade, to six hours and 40 minutes. And men ages 30 to 44 are the worst offenders: Thirty percent of them say they log less than six hours of sleep at night. (For me, I think this is almost everywhere in the world)
Cheating on sleep, you're limping through life with the cranial equivalent of a torn calf muscle. Scarier still, people who are sleep-deprived often don't even know they've turned into zombies
Accumulating a sleep deficit also leads to "microsleeps" while you're awake. "Your brain becomes unstable and will go 'off-line' for half a second. The more sleep-deprived you are, the more frequent and longer the lapses.
Frequently needing to pee in the middle of the night might indicate a health problem
That first stumble to the bathroom in the dark can be chalked up to the beer you drank. The second one can spell trouble. "If you habitually take two or more bathroom trips a night, you probably have obstructive sleep apnea, where the soft tissue at the back of your throat blocks your upper airway during sleep(Sometimes make you snoring if not roaring at night), stopping your breathing for anywhere from 10 seconds to a minute or even longer. This can occur hundreds of times in a night, depriving you of restorative deep sleep and starving your vital organs of oxygen. No wonder sleep apnea has been linked to heart disease, hypertension, and mood disorders.
But why does it wake you up to pee?
Because those mini-suffocations result in lower circulating oxygen levels, your heart pumps harder, raising your blood pressure. As excess fluid builds up in your veins, a feedback loop triggers the release of a pressure-relieving diuretic, making you need to pee.
An enlarged prostate and high blood sugar can also prompt middle-of-the-night bowl breaks.
But with those conditions, you'll pee a lot day and night.
A post lunch crash is a telltale sign of poor nighttime sleep, as is dozing in meetings, theater performances, or similar environments. But again watch if you take too much carbohydrate in the morning you may end up with.
