How long should deep sleep last?

Deep sleep is like the dessert of your sleep cycle, right? The most satisfying part! You need a good solid chunk of it, maybe an hour or two, to really feel refreshed. Imagine having a big, delicious meal, and then a tiny dessert, not fair! Good deep sleep makes everything taste better the next day.

Oh, this is something I've constantly worried about with my own sleep! I used to check my sleep trackers obsessively. They say about 15-25% of your total sleep should be deep sleep, so if you sleep 7-9 hours, around 1-2.5 hours. It's normal to feel anxious about getting enough of it, but focus on overall sleep hygiene too, not just one phase.

I used to panic when my sleep tracker showed little deep sleep. But then I learned it's normal for it to be around 1-2.5 hours for adults getting 7-9 hours of total sleep. It naturally varies. As long as you feel rested, don't worry too much about hitting exact numbers. The overall sleep quality matters.

My fitness tracker usually shows around 15-25% of my total sleep as deep sleep. So if I get 7 hours, it's typically 1 to 1.5 hours. It's crucial for physical recovery and memory consolidation. If your deep sleep is consistently low, maybe check with a sleep specialist.
