Did you know that there are as many as five stages of sleep? Yes, that is true, according to sleep researchers, you may be conveniently dosing or in a deep slumber or somewhere in-between. However, for the purpose of this blog we are making things simple to understand by clubbing together the various stages of sleep and bringing them down to just two — deep sleep and REM.
Here, we explain
Difference Between Sound Sleep and Healthy Sleep
The process of deep sleep begins after the state of light sleep. In this stage of sleeping, our body is relaxed and becomes less responsive to outside interruptions. It usually results in the relaxation of muscles and a more regular heart rate. Deep sleep helps in our physical healing and growth by secreting hormones which are associated with cellular rebuilding. Moreover, deep sleep also strengthens our immune system.
The name REM refers to rapid eye movement, as this is what happens in this stage of sleep. Where deep sleep is all about relaxation and rebuilding of the body, REM is about cleansing and restoration of brain function. REM is the stage where dreams occur and as a result, our heart rate and breathing accelerates. Having REM is very important for emotional regulation and memory functions of our brain as in this stage the brain is also clearing out things that are not needed. Finally, REM also boosts protein synthesis at the cellular level and hence is beneficial for the body as well.
Now that we know about how sleeping soundly can help us recover physically and emotionally, the question that needs asking is how to get a sound sleep? Because having a sound sleep that includes both Deep Sleep and REM is what we call a Healthy Sleep.
If you have noticed, in the above descriptions of Deep Sleep and REM, there is one common point, that is breathing and heart rate. Breathing in clean air while you are asleep is very important for having a healthy sleep. Clean air also helps in regulating your heart rate as there is less stress on your lungs and immune system. That’s why it is important to discuss the menace of indoor air pollution in urban homes.
Indoor air pollution is caused by particulate matter (also known as PM), volatile organic compounds, dander and hair. These pollutants are generally released by household equipment, upholstery and kitchen & horticulture activities. While you can minimize the risk by ensuring optimal ventilation, the rising environmental pollution negates a lot of its positive effects on indoor air quality. It is here where smart home technologies offer a solution.
Home air purifiers with HEPA filters are among the must-have smart home products today. HEPA filters are considered the industry standard for air filtration and are often combined with activated carbon filters to provide additional protection from pollutants like VOCs, odors and gaseous elements. Air purifiers with these filters can remove more than 99 percent of indoor air pollution by recycling the ambient air.
So, if you are living in an urban area like Delhi NCR or Bangalore, where air pollution is constantly high, consider buying an air purifier for your home or office. It will ensure that you and your family enjoy a deep and healthy sleep, waking up refreshed and rejuvenated, always.
