How important is it for the body to get the enough amount of sleep it needs? Very important! There have been thousands of studies conducted in this department and they all concluded to one thing: for optimal functioning, the body must have enough sleep.
Sleeping is essential for the process of integrating events into the long-term memory, but it also helps to restructure cells.
Recent studies have shown that sleeping less than 7 hours per night can increase the risk of gaining weight, by stimulating the activity of the hormones which are directly responsible for our appetite.
Less than 6 hours of sleep per night can have serious consequences on the cognitive function of the brain. Its ability to function properly can be shadowed heavily the next day if during the previous night the sleep lasted between 4 and 6 hours. The lack of sleep is also a risk factor that can trigger depression. The studies have shown that insomnia might even precede depression in some cases.
Sleep deprivation on a long term is a risk factor for other conditions. Here are some of them:
- Diabetes – People who tend to oversleep during the day – as this is also bad for the body – have a 56% chances of suffering from type 2 diabetes.
- Decreased immune function – Sleep plays a great role in strengthening the immune system so that it can defend the body when harmful agents attack it.
- Cardiovascular diseases – According to a study, women who get less than 4 hours of sleep per night will increase their chances of getting heart conditions.
How to improve your sleep?
- The first thing you need to do is to maintain a natural rhythm of exposure to the sun during the day and to darkness during nighttime. Most people will have sleep problems because they tend to spend too much time indoors, away from the sunlight. During the night, they will also spend too much time in an extremely bright artificial environment.
- Make sure that you get 15 minutes of sunlight every morning. You will send your body the message that the day is here and it will stop being confused about the weaker light symbols later. The room in which you sit should be aired and you should allow light to pass for about 30-60 minutes every day.
- If, for some reason, you cannot get outside, you can use a gadget, a small therapy device that can be placed on your desk. Use it twice per day for about 15 minutes to make sure that your circadian rhythm is being balanced.
- If you have the possibility, stay somewhere close to nature. The sounds that come from nature are proved to have a powerful effect on the quality of one’s sleep.
