How Soundproof Windows Improve Sleep Quality & Stages

January 19, 2022

Did you know that sleep is divided into two major types? They are: Non-REM (Rapid eye movement) or quiet, sleep and REM (Rapid eye movement), or dreaming, sleep. Sleep specialists have called non-REM sleep “an idling brain in a movable body.” During this stage thinking and most physiological activities slow down but a person may have some body movements. REM sleep has been described as an “active brain in a paralyzed body.” It is during this stage that dreaming occurs. While non-REM sleep consists of multiple stages, REM sleep is one single stage. We will discuss these stages in detail below.

Note: During your complete sleep cycle, REM sleep makes up for only 20 to 25% of your sleep, and this is a good average for healthy adults.

Understanding Noise-Related Sleep Disturbance: The Case for Soundproof Aluminum Windows

According to WHO, the target limit of outdoor night noise is 40 dB. Ordinary aluminum windows, do not offer better sound proofing – the outside noise can go as high as 70 dB, even during the nights. While the desired noise indoors is 30-40 dB. Instead of letting sound be a constant irritant, install soundproof windows by Eternia.

Air-tight design with custom developed accessories provide better noise insulation

The high-performance glass and superior airtightness of our soundproof windows can reduce noise up to 35dB, ensuring that you enjoy a good night’s sleep with minimum noise disturbance.

Stages of sleep and what happens during them

Stage 1 of Non-REM Sleep: Even the slightest noise can disturb this sleep phase

During this stage, your eyes are closed but you can be easily interrupted by a disruptive noise. This stage is also known as the ‘dozing off’ stage when the body is starting to relax but it has not fully relaxed. During this stage, the brain activities start slowing down. This stage usually lasts for 5 to 10 minutes. If not disturbed during this phase, the person sleeping can quickly move to stage 2.

Stage 2 of Non-REM Sleep: This is the first stage of established sleep

During this stage, your heart rate slows down further, your body temperature drops, and eye movements stop. Though the brain activity slows down, there are still short bursts of activities – which are called sleep spindles. This stage accounts for 50% of the total sleep cycle.

Stage 3 of Non-REM Sleep: This is the deepest stage of sleep

This is the most restorative stage of sleep. During this stage, the body is completely relaxed, there are no eye movements, and your breathing slows and becomes more regular. It is during this stage that the body starts its repair work. Experts believe that this stage is important to strengthen your immune system. It is important to note that during deep sleep, disturbances such as noises or activity in the nearby surroundings may fail to wake the sleeping person. Stage 3 typically lasts 20 to 40 minutes.

REM: Dreaming Sleep

People usually enter REM sleep within the first one and half hours of falling asleep. The brain activity during this stage resembles activity during waking hours. Your body temperature rises. Your heart rate and breathing also increase. Despite all these, your body hardly moves.

It’s important to note that sleep does not progress through the four stages in sequence. The cycle keeps on repeating throughout the night.

Lack of sleep is not good for your body and mind

  • Weakened immunity
    According to a study, long-term sleep deprivation can adversely affect the immune system.
  • Weight gain
    It has been found that people getting less than 6 hours of sleep at night are more likely to be diagnosed as obese.
  • Chronic health conditions
    Long-term sleep deprivation has been linked to various chronic conditions, such as diabetes and cardiovascular disease.
