What is REM sleep?

Rapid eye movement sleep or REM sleep was first discovered in the 1950s when scientists studying sleeping infants noticed distinct periods when their eyes raced from side to side which earned REM sleep its name. It happens at regular intervals during the sleep period, typically every 90 to 120 minutes. It is the fourth out of four total stages of sleep. In contrast to other stages of sleep, in which your brain waves slow down, your brain is highly active during REM sleep, and your brain waves become more variable.

The role of REM in sleep cycles

All sleep is important, but REM sleep, in particular, plays an important role in sleep cycles and involves various functions:

Memory consolidation,
Emotional processing,
Healthy brain development, and
Dreaming.

The physical signs of REM sleep

Traits unique to REM sleep include:

Quick-eye movement
Increased brain wave activity that’s more similar to wakefulness than any other stage of sleep
Complete loss of muscle tone
Irregular breathing
Elevated हृदय गति
The ability to be awoken more easily than during non-REM sleep

The importance of REM sleep

Let us look at the important role REM sleep plays in:

Memory consolidation and learning

During REM sleep, your brain processes new learnings and motor skills from the day, committing some to memory, maintaining others, and deciding which ones to delete. This is how memory consolidation which is the process of preserving key memories and discarding excessive information occurs in REM sleep. Some memory consolidation also occurs in deep sleep, which is a non-REM stage.

Emotional regulation and mood

Your brain processes emotions during REM sleep. Dreams, which are more vivid in REM sleep, may be involved in emotional processing. Also, your amygdala, the part of your brain that processes emotions, activates during REM sleep. It is also associated with better मानसिक स्वास्थ्य and as a consequence – emotional regulation and mood.

Immune function and overall health

During REM sleep, your immune system releases proteins called cytokines, some of which help promote sleep. Certain cytokines increase when you have an infection or inflammation or are under stress. Sleep deprivation may decrease the production of these protective cytokines. Our bodies also produce T-cells during sleep, white blood cells that are your body’s immune response to an infectious disease.

Factors affecting REM sleep

Various factors negatively impact REM sleep:

Lifestyle habits: Alcohol, caffeine, and screen time

Substance use has a strong impact on REM sleep. Caffeine and alcohol are known to suppress it. Also, screens can disrupt it, impacting memory and cognitive function. So, you must limit your screen time and avoid substance use. On average, you should stop drinking caffeine four to six hours before bed.

Opioid or narcotic pain medications – used to mitigate the effects of pain
Benzodiazepine medications – sometimes used to treat sleep disorders
Antidepressant medications – used to treat depression
Lithobid (lithium) – a mood stabilizer used to treat mood disorders

Now that you understand the importance of REM sleep for your well-being, here are some tips you can follow to enhance it:

Create a sleep-conducive environment

Look around your bedroom to identify factors that may prevent you from getting a good night’s sleep. Bright lights from the outside, a TV blaring in your room, and hot temperatures can prevent you from getting enough REM sleep. Hang up blackout curtains that block outside noises and lights, and turn off the TV when it is time to sleep. Make your bedroom comfortable, cozy, and relaxing.

Try and establish a consistent sleep schedule

Wake up and go to bed at the same time every day – not just on weekdays but also on weekends. Your body will eventually get used to a sleep schedule, you will be more alert and sleepy at the appropriate times.

Use stress management techniques

If you lie awake at night worrying or thinking about things bothering you, try practising सचेतनपूर्ण मेडिटेशन. To practise meditation to fall asleep, close your eyes and focus on your surroundings in the present moment. Breathe deeply, feel the bed sheets against your skin, and listen to the sound of your fan. When your mind starts to wander, refocus on the present moment. It can help reduce insomnia and improve sleep quality.

Kiwifruit – contains sleep-promoting compounds: melatonin, potassium, magnesium, and calcium.
Walnuts – contain a few compounds that regulate sleep, including melatonin, serotonin, and magnesium.
Fatty fish – may help improve sleep because they contain vitamin D and omega-3 fatty acids, that help regulate serotonin.
