Sleeping is an integral part of our life. We need it to “recharge” our bodies so we are ready for new daily challenges. However, a lot depends on the time we spend sleeping. So, it is important to remember that the quality of sleep plays a much crucial role.
When we rest, our body experiences various sleep phases. Usually, they are differentiated into two main categories: REM (when we move our eyes) and NREM (when the eyes are held still) sleep. As you may guess, deep sleep occurs during the non-REM stage as our body slows down brain activity.
If you want to learn more about deep sleeping, stick with us as we present to you 5 interesting facts about it.
1. Your temperature does down. Everything within you begins to chill down. You produce less heat and keep it for a longer time. This, according to one idea, aids in energy conservation and restoration.
2. You preserve energy. During this phase, your metabolism is slowed. Scientists say that by doing so, your body recovers itself. For adults, it is extremely important as the lack of deep sleep might lower glucose tolerance. This implies that you will be unable to process sugar as efficiently as it should be.
3. Deep sleep has an immense effect on our immune system. Do you notice how tired and sleepy you get when you’re unwell? This happens due to the fact that sleep activates your defense mechanism. Studies suggest that your body receives more deep sleep to fight the infection. And not just that.
Deep sleep also helps to reduce the level of in-body substances that can cause inflammation, boosts your immune system on a regular basis, and assists vaccinations to settle in your body.
4. Deep sleep has an impact on our cognitive abilities. When your brain falls into a deep sleep, its waves shift. Their amplitude becomes larger and slows down. They are also known as delta waves and play an important role in configuring your ability to learn and remember things.
Another vital thing that happens during a deep sleep stage is that your brain gets rid of a specific protein – beta-amyloid – often associated with the development of Alzheimer’s disease.
5. Lack of deep sleep can lead to various diseases. If your sleep quality is poor, it will definitely have a negative impact not just on your physical but also mental and emotional well-being. As a result, you get yourself endangered by numerous illnesses: dementia, cardiovascular disease, diabetes, etc.
As you can see, sleeping is one of the most vital things in our lives. Its absence or bad quality can lead to disastrous outcomes. If you want to get more deep sleep, you can consider taking a hot bath right before bedtime. Your body will become more relaxed, and it will be easier to fall asleep.
Also, you should avoid consuming stimulants like alcohol and caffeine before going to bed as there is a chance that they will interfere with getting enough rest.
Just remember to care about your sleep and stay healthy!
