how much deep sleep should we get a night
Hereâs a surprise: a healthy dose of deep sleep is about 20% of overall sleep. Thatâs less than I thought. If this is the case, then even my worst night with 30% would be way above the norm. If we only had three phases, I neednât worry. have data from the past year. Last night I got 2 hrs 36 minutes of âdeep sleepâ, and my total sleep was over 8 hours. My data shows sleep that is completely interrupted-the largest band of deep sleep was 31 minutes, most are under 9 minutes.
