What percent of sleep should be deep?

Bete, my grandmother always said a good sound sleep is the best medicine. You just need to sleep peacefully, without worries. That's true deep sleep, where you feel completely refreshed when you wake up.

Around 20-25% is the sweet spot for deep sleep. If you're not getting enough, you'll feel it the next day. Focus on good sleep hygiene – dark room, cool temperature, no phone.

My doctor explained that ideally, adults need around 1.5 to 1.8 hours of deep sleep per night, which translates to roughly 20-25% of an 8-hour sleep cycle. It's crucial for physical restoration and memory consolidation.

For someone managing diabetes, good quality sleep, especially deep sleep, is very important for blood sugar regulation. I try to ensure I'm not having any sugary snacks late at night to avoid disturbing my sleep cycle.

For good recovery after workouts, deep sleep is super important. I try to optimize for it by having a light dinner and avoiding screen time before bed. It helps a lot with muscle repair and overall energy.

It's a good chunk, probably 20% or so. Regular exercise can definitely improve sleep quality, including deep sleep. Just make sure not to exercise too close to bedtime as it can be stimulating.
