Most adults should aim to get about 1.5 to 2 hours of deep sleep per night, which typically makes up around 20-25% of total sleep time. Since the recommended total sleep for adults is 7-9 hours, this deep sleep duration aligns with roughly 10-25% of sleep time spent in deep sleep. This stage is vital for bodily repair, immune function, and feeling rested. The exact amount of deep sleep needed can vary based on age, health, and individual factors, but generally, adults require about 90 to 120 minutes of deep sleep to maintain optimal health and wellbeing.
