how much sleep do you need ? Sleep Quality Vs Quantity

How much do you sleep per day? How much sleep do modern people need? Adequate sleep time refers to the amount of sleep time during which you are not tired during the day without other stimulation. The amount of time you sleep varies from person to person and depending on your age. Newborns sleep for 17-18 hours, but as they get older, the amount of sleep gradually decreases, and as they get older, it is said that they sleep 7-8 hours. In this video, I want to find out what sleep time is right for me. The amount of time you sleep is important, but so is the quality of your sleep. If you don't get a good night's sleep, you won't feel refreshed even after a lot of sleep, and you won't recover well. When we fall asleep, we fall asleep while repeating a sleep cycle consisting of light sleep (non-REM sleep stages 1 and 2), deep sleep (non-REM sleep stage 3), and REM sleep (dream sleep). Deep sleep accounts for about 20% of total sleep, and it mainly occurs within 2-3 hours of falling asleep, that is, within 2-3 hours of falling asleep, the first half of sleep. , appears mainly at dawn, and has the function of enhancing memory and eliminating emotional stress. When you sleep continuously, deep sleep in the first half of sleep and REM sleep in the second half of sleep appear overnight, resulting in physical recovery and recovery of the mind and brain. Therefore, it can be said that good sleep is adequate sleep to sleep 7-9 hours continuously without waking up in the middle. #Sleep #Sleep quality #Quantity #Insomnia #optimalsleep #REM sleep
