What are the stages of sleep?

I used to get so anxious about not getting 'perfect' sleep, which actually made my insomnia worse. Sleep basically goes through 4 stages, cycling through light, deep, and REM sleep several times a night. Don't stress too much about tracking every minute, just focus on keeping your bedroom quiet and comfortable.

There are 4 main stages of sleep, including the deep restorative stages and the dreaming REM stage. Having a warm cup of chamomile tea or a light dinner of simple khichdi at least two hours before sleeping can greatly support these natural cycles. Avoid heavy dairy or spicy foods late at night as they can disrupt deep sleep.

Actually, we go through 4 stages of sleep—three NREM stages and one REM stage, yaar. The whole cycle repeats every 90 minutes or so while we are asleep. If you wake up feeling super tired even after 8 hours, you might be missing out on deep sleep, so maybe check with a doctor.

I am just starting to learn about sleep hygiene, and I read there are 4 stages of sleep. Is it normal to wake up briefly between these stages, or should we sleep continuously without waking up at all? If anyone knows about this, please do share.
