Sleep is divided into five stages: light NREM sleep, deep NREM sleep, and REM sleep. While all stages are necessary, the amount of time spent in each stage varies depending on age. Newborns, for example, tend to get the most REM sleep, while older adults need less. In this article, we will explore the different stages of sleep and the role they play in maintaining health and wellbeing. We will also discuss factors that can impact sleep quality and duration, such as age, recent sleep patterns, and sleep disorders. By understanding the sleep cycle and its importance, we can make informed decisions about our sleep habits and overall health.

What You'll Learn
Deep sleep is when the body repairs itself
Sleep is divided into five stages: light NREM sleep, deep NREM sleep, and REM sleep. Deep sleep is when the body repairs itself. During this stage, brain waves are at their slowest in frequency and highest in amplitude. This is when the body relaxes fully and repairs injuries and reinforces the immune system.
Deep sleep is the third stage of sleep. In this stage, your brain waves are slow but strong. Your body takes advantage of this very deep sleep stage to repair injuries and reinforce your immune system.
REM sleep, on the other hand, is when we tend to dream. Your eyes move quickly beneath your eyelids, but your muscles usually do not move. Experts believe most of our dreaming happens during REM sleep.
The amount of sleep we need varies by age. Newborns tend to get the most REM sleep and may enter a REM stage as soon as they fall asleep. Older adults, on the other hand, tend to need less REM sleep.
To calculate how much deep sleep you need, first determine how much sleep you need overall. Most adults should aim for at least seven hours of sleep per night.

The amount of REM sleep you need can vary depending on your age. Newborns tend to get the most REM sleep out of anyone and may enter a REM stage as soon as they fall asleep. On the other hand, older adults tend to need less REM sleep than younger adults, children, and babies.

Stage 1 sleep is when we transition to sleep
All stages of sleep are necessary and important for health and wellbeing. However, the first stage of sleep is when we transition to sleep. During this brief, drowsy stage, our breathing and heartbeat start to slow down. As we move through the stages of sleep, our breathing and heart rate slow even more. While the amount of sleep we need varies by age, the CDC recommends at least seven hours of sleep in every 24 hours for adults. Newborns tend to get the most REM sleep and may enter a REM stage as soon as they fall asleep. On the other hand, older adults tend to need less REM sleep than younger adults, children and babies.

Stage 3 sleep is the deepest sleep of the sleep cycle, when brain waves are at their slowest in frequency and highest in amplitude. This is when the body takes advantage of the very deep sleep stage to repair injuries and reinforce the immune system. As the night goes on, we spend more and more time in REM sleep. REM sleep is when we tend to dream, and our eyes move quickly beneath our eyelids. Our brain activity is similar to that of a person who is awake, but our muscles usually do not move.
