Is there any way to clean your brain besides sleeping?
This question came from the comments on this video:
Your brain washes itself while you sleep .. without sleep, waste builds upHearing Spanish on YouTube? Tap ⚙ › Audio track › English
No, what has been studied so far points to sleep. The glymphatic system, which flushes the brain with cerebrospinal fluid, switches on during sleep. In mice, the space between brain cells opens up during sleep and waste clears faster, including a protein that builds up in Alzheimer's. So protect your sleep.
Does sleep from sleeping pills also clean the brain?
Not necessarily. In mice, zolpidem, a sleeping pill, lowered this brain cleanup. This is an animal finding, so any change is up to whoever prescribed it.
If you work nights, how can you protect your brain?
The foundation is sleeping well during the day: a dark, cool, quiet bedroom and a schedule as steady as you can keep. A short nap before your shift also helps. As for medication, your doctor can weigh whether one suits you based on your shifts and how you sleep.
How many hours should you sleep for your age, and what if you sleep too much?
It varies by age: 9 to 12 hours for ages 6 to 12, and 8 to 10 for teens. For a healthy adult, the American Academy of Sleep Medicine advises 7 or more hours. If you need 10 to 12 hours and don't feel rested, tell your doctor how long you sleep, how you wake up and if you snore. That helps rule out an underlying cause.
