The Short and Simple Answer: How Much REM Sleep Do You Need?
Generally speaking, adults require 1.5-2 hours of REM sleep every night. This duration is normally about 20 to 25 percent of the total sleep. Children and adolescents need a lot of REM sleep since their brains develop very quickly. With aging, the amount of REM sleep may decline slightly, but it still plays a crucial role in brain and emotional health.
What Exactly Is REM Sleep and Why Is It So Important?
REM is an acronym for Rapid Eye Movement.
This phase of sleep is characterised by rapid eye movements, vivid dreams, and brain activity at a higher level than usual. Hence, it is often referred to as the dreaming stage, as the majority of dreaming also occurs during REM.
REM sleep is extremely necessary for various reasons:
- First of all, it is one of the main factors that contribute to the consolidation of memory and learning.
- In addition, it is a regulator of the person’s mood and emotional health.
- Furthermore, it is the source of brain development in kids.
- Moreover, it is the one that makes your body get over the stress and also helps to energize you for the rest of the day.
- Besides, it is the main instrument in supporting long-term healthy brain function.
If a person does not get sufficient REM sleep, their brain will not be able to enjoy all the necessary benefits that come with it, and this will reflect on their mental sharpness, mood, and physical condition as well.
The Different Sleep Stages and How They Work Together
Sleep is composed of multiple cycles, each about 90 minutes long, and contains different stages:
- Stage 1 (Light sleep): It is the change of the state from being awake to sleeping.
- Stage 2 (Lighter deep sleep): The body temperature is lowered, and the heart rate is slowed down.
- Stage 3 (Deep sleep or slow-wave sleep): This stage is the most restorative one for the body’s repair and immune functions.
- REM sleep: The brain activity intensifies, and dreaming takes place.
These stages cycle several times during a night, and the length of REM intervals increases later in the night.
How the Amount of REM Sleep Changes as You Get Older
Infants can invest almost one-half of their total sleep in the Rapid Eye Movement (REM) sleep, which is the main sleep stage to support brain development. Teens also receive more REM sleep than grown-ups as their bodies and brains evolve. The chest of an adult takes about 20-25% REM sleep, which accounts for 1.5-2 hours per night.
It happens that REM sleep decreases a little during old age, but it never goes away. An elderly person may feel that his sleep is shallow all the time with a little REM duration. However, REM is still necessary for the following:
- Keeping brain functions at a high level.
- Emotional stability.
- Sleep phase.
What Happens When You Don’t Get Enough REM Sleep
The shortage of Rapid Eye Movement sleep has negative consequences on the brain and the rest of the body. Some of the common symptoms that may appear when REM is not enough are:
- Memory issues and trouble with acquiring new knowledge.
- Sudden changes of mood, being annoyed easily, or feeling more pressured.
- Decreased capability to cope with emotional difficulties.
- Impaired decision-making skills.
- A decrease in energy levels and the occurrence of tiredness during the day.
- The possibility of developing some health problems, like being overweight and having a weakened immune system, increases gradually.
