Sleeping is one of my favorite activities. I don't consider it a waste of time like many people out there, I fall asleep easily and I usually wake up refreshed. I try to have my healthy share of at least 7 hours per night and I feel sorry for those who simply can't do this as they are either too busy, too stressed or used to having sleep problems.
I saw the other day on youtube that there are dozens of playlists that aim to help you sleep better. Many of these are called or related to Delta Waves. So, let's see what these waves are and how they influence our sleep pattern.
Delta waves are high amplitude brain waves humans normally have. Their frequency varies from 1 to 4 Herts. These waves are produced in the brain's right hemisphere. They are correlated to our unconsciousness and subconsciousness. These waves can be monitored using special devices and studies have correlated them with the sleep stage called 'deep sleep'. There are 4 stages of sleep.
Deep sleep is the stage in which we are breathing slowly, in fact, the brain's function and activity also slows down and we are simply having the best, most intense part of our sleep. You are not aware of what is happening around you in this stage. Deep sleep is what we actually need in order to restore our body's energy and feel refreshed.
Delta waves start to be produced as the body enters the 3rd stage of sleep. These waves somehow mark the passage step between light sleep and deep sleep During the 4th stage, Delta Waves become more predominant as they account for more that 50% of the brain's activity.
Delta waves not only give you that good knock-out sleep you're longing for at the end of a busy day, but they also support different body functions such as that of the digestive system, the heart or the kidneys. Moreover, they help produce the human growth hormone and other hormones which are essential to our well-being.
Other benefits of delta waves is that they boos our immunity, prevent aging and healing and are even linked to a higher level of empathy and a better intuition.
So, next time you don't know what playlist to choose for a good night sleep, why don't you opt for one that says you'll produce more Delta Waves. I tried it myself, it's strange at first, but it really does help you relax and sleep deeper.
