how much deep sleep should i get in a night

The recommended amount of deep sleep for most adults is typically around 1.5 to 2 hours per night, or roughly 10% to 25% of total sleep time. This generally translates to about 60 to 120 minutes of deep sleep if one sleeps 7 to 8 hours in total. Deep sleep is crucial for physical recovery, emotional balance, and overall health, and the amount needed can vary with age, activity level, and individual health factors. Feeling refreshed and rested upon waking is a good indicator that enough deep sleep has been achieved.
