What is light sleep?

 Light sleep refers to the type of sleep we are in during the first two stages of nREM sleep. As its name suggests, the light of sleep at the time was very different from a deep sleep, which is the third stage of non-REM sleep. Usually, the first stage of non-REM sleep represents about 3% of our total sleep time.

Our brain does not linger so much at the first stage, as it merely acts as a transition between our waking time and sleeping time. Any light sleep occurs at the 2nd stage of non-REM sleep. It's where most adults spend more than half their nights. For those who ask, "what is light sleep?" these are necessarily the first two stages of our sleep cycle.

Some people have asked Reddit not to sleep and what is the difference between deep sleep and light sleep? You have probably heard that people who sleep in the light can wake up in a flash with the most luminous noise, and there are also those who sleep deeply, no matter what noise surrounds them. What's the difference between the two, anyway?

Light sleep

As previously mentioned, this stage of non-REM sleep is the lightest sleep which means you can wake up quickly at this point. The first step is to switch from awake to light sleep, which usually happens in the second stage of non-REM sleep. That's where we spend half our sleep every night. When you are asleep at this stage, you will be able to get to The Awakening Stage easily because your brain has not yet made the transition to deep sleep.

Deep sleep

It is also called delta sleep or slow wave sleep, where we disengage from our environment while we sleep. We need to be in a deep sleep to receive its healing properties. We don't dream that much.

The Light Stage Of Sleep

What happens in a light sleep phase? There are Reddit users who think they don't need to pay much attention to non-REM sleep because all the benefits to our brain and body occur when we enter deep sleep. Researchers say that all stages of sleep play a role in our mind and body, which is why you need to undergo the various stages of sleep to feel stimulated and refreshed.

In the sleep-wake cycle, we first enter the non-REM stage where Stages 1 and 2 is where light sleep occurs. The first stage is the lightest of sleep where it prepares the body to go to a lighter sleep in preparation for deep sleep which is the third stage. The second step is where the sleep spindles occur which are essentially bursts of brain activity.

A good night's sleep is essential to our health and well-being.that's why we have to make sure that we keep our circadian rhythm as much as possible. Although there are some who can sleep light and always wake up feeling refreshed, there are those who need to go through several sleep patterns to get a good night's rest. Let's see how deep and light sleep patterns work.

Non-REM sleep

There are three stages of non-REM sleep that we go through with each step lasting 5 to 15 minutes. Your body will have to go through every level before they reach.REM sleep. The first step can take 5 to 15 minutes when your eyes close, but it's easy to wake up. The second stage is where light sleep begins. Your heart rate slows as your body temperature drops. This means that your brain and body are preparing for deep sleep. This is the third stage where you enter the deep sleep phase. In this phase of REM sleep without REM sleep, it will be difficult to wake up from the bed, but if you manage to wake up, you will probably feel disoriented for a few minutes. It is in the third stage of sleep that a restorative sleep occurs.

REM sleep

Rapid eye movements or REM sleep tend to occur 90 minutes after you enter REM sleep. The first phase of your rem sleep tends to last about 10 minutes. At each stage of sleep, the duration of your REM sleep lengthens. When you are in REM sleep, your heart and breathing speed up.

How much sleep deep compared to light sleep if you get
There are a lot of people who wonder, “how much deep sleep should you buy versus light sleep?" as we have read, deep sleep and REM sleep play a role in our brain and body. This is what we should have for REM sleep and REM sleep.


As mentioned previously, the first step of this non-REM step usually takes 10 minutes as you are still in transition to the sleep phase. When you enter the real non-REM period, your body temperature, as well as your heart rate, will slow down in preparation for a deep sleep which is the third non-REM stage. Most of the time, when we sleep at night, we spend 50% of non-REM, where 20-25% in the deepest non-REM stage. When you're in a deep sleep, brain waves are slow which means there's not much activity or dream happening here. Light sleep often remains in the first two stages non-REM.


After going through the first three stages of the nREM, your body will enter the REM where brain activity will increase. Eye movements will occur at this point because your brain is active while it screens and processes memories and information. You will need to spend 20-25% of your sleep each night at this stage.

Now that you have an idea of how much light and deep sleep you will need each time you go to bed, those who suffer from obstructive sleep apnea, or difficulty breathing at night, you will need to take steps to correct it. The same is true for other age-related macular degeneration if you want to be able to respond to the necessary light and deep sleep to keep your brain functioning, to preserve long-term memory, and your body to stay active and healthy.

Mild Sleep Depression

Sleep depression is as real as the sleep disorders we experience, such as sleep apnea, insomnia, night terrors, etc.according to the American Journal of Epidemiology, sleep quality is affected at night when exposed to light. They added that seniors might have difficulty sleeping at night when there is artificial light. According to Kenji Obayashi, the co-author of the study said that there is a strong link between sleep deprivation and depression, especially in the elderly, because their brains have difficulty slowing down.

Although exposure to light may not be the only reason people feel depressed when they sleep, it may be because exposure to artificial light can disrupt their sleep and brain waves, so they don't get enough rest. And when we lack quality sleep at night, you can expect a variety of health problems to appear, such as Alzheimer's disease, sleep breathing disorders, and others because we don't have enough rest on time.

It seems that exposure to light, while we sleep at night, can trigger changes to our melatonin that affect our body clock. Melatonin is the one that helps our body rest at night. This is why some people find it difficult to fall asleep, even when there is a little artificial light in their room. Obayashi added that even though the elderly are affected by this problem, young people are more likely to suffer from sleep disorders, especially when using their gadgets. Wearing blue-blocking glasses can help reduce tension in the eyes so that they can sleep better at night.

For those who have trouble sleeping because of the depression due to the introduction of artificial light in their bedroom while they sleep, some experts recommend the use of light therapy to correct their body clock. Listening to a sleep podcast can help your brain get into a relaxed state as well.
