Deep sleep, also known as slow-wave sleep, is an important stage of sleep that is characterized by slow brain waves and is thought to be critical for physical restoration and memory consolidation. The amount of deep sleep that a person needs can vary depending on several factors, such as age, sex, and overall health. However, as a general guideline, adults should aim for at least 1-1.5 hours of deep sleep per night, which typically makes up 15-25% of the total sleep time.
It’s important to note that the amount of deep sleep a person gets can be influenced by several factors, such as lifestyle habits and sleep disorders. For example, poor sleep quality, certain medications, alcohol consumption, and sleep disorders such as sleep apnea can all disrupt deep sleep and prevent the body from fully restoring itself during the night.
To improve the amount of deep sleep you get, it’s important to practice good sleep hygiene, such as establishing a regular sleep schedule, creating a relaxing sleep environment, avoiding caffeine and alcohol before bed, and limiting screen time in the evening. If you have concerns about the quality of your sleep, you may want to talk to a healthcare professional for guidance and support.
