Deep sleep is a stage in the sleep cycle that is necessary for proper brain function and memory. While most people need 7-9 hours of sleep per night, the amount of deep sleep we need varies from person to person and can even change from night to night. Sleep experts don't have set guidelines for deep sleep as it's constantly changing and individual. However, getting enough healthy sleep overall is important as it allows the brain and body to repair themselves and feel restored.

Sleep needs are genetically determined, but they can change from night to night
Deep sleep is a stage in the sleep cycle necessary for proper brain function and memory. It is also called slow-wave sleep. Most people need seven to nine hours of sleep per night, but working out how much deep sleep they need is more complex. The two main categories of sleep are called rapid eye movement (REM) sleep and non-REM sleep, and each has important stages. People in good health will cycle through these stages in a somewhat regular pattern as they sleep, and a full night's rest means cycling through these stages a few times before waking up.
Your brain works hard to make sure it spends the right amount of time in deep sleep, as well as every other sleep stage. Getting around 1.5 to two hours of deep sleep is crucial for feeling rested and staying healthy.
