how many hours of deep sleep do you need a night?
Adults typically need about 1 to 2 hours of deep sleep each night, which should account for roughly 15-25% of their total sleep. Since the recommended total sleep duration for adults is about 7 to 9 hours, spending 1 to 2 of those hours in deep sleep is considered healthy and sufficient for most people.

However, the need for deep sleep can vary depending on factors like age, overall health, and lifestyle. Younger individuals, such as children and teenagers, require more deep sleep to support growth and development, while older adults may naturally experience a decline in deep sleep as part of the aging process.
