Contrary to popular belief, lack of sleep does not make us just dazed and lazy, but can have serious consequences for our health. Below you will find a list of things that are happening in our body when we chronically don’t get enough sleep.

We are prone to forget things – To function properly, your brain needs some rest. Although the brain does not cease to work completely when we fall asleep, its activity is significantly reduced (basically it rests). If you do not sleep enough, you will not only start to forget things, but will have difficulty remembering and learning new things. It is important that the brain gets enough sleep in order to organize the things that you have learned during the day.

Increased risk of diabetes, heart disease and cancer – Various studies have indicated that those who do not sleep enough, specifically less than five hours each day, have increased risk of developing type 2 diabetes. This is because sleep deprivation affects your glucose metabolism in the body. Sleep deprivation increases the heart pressure. Also, research shows that lack of sleep increases the risk of breast and prostate cancer.

The skin is ageing faster – People that don’t get enough sleep are more prone to having wrinkles and pigmented spots on their skin. The same goes for those who sleep enough, but don’t have quality sleep. Therefore, if you want to have a nice soft skin, the dermatologists advise is to try to sleep well and enough.

Decreased concentration – If you are sleepy, or sleep less, your attention begins to abate. This can directly reflect in the work that you do. Drowsiness can cause accidents at work or in traffic. These are extremely serious matters, which is why experts advise: if you are sleep deprived, try to have some sleep during the day.

Increased chances to gain weight – One study from 2004 indicated that people who sleep six or fewer hours have a 30% more chances to get fat. Lack of sleep increases hunger and appetite, and these are the two main things that are basics for getting fat. And not only that: lack of sleep makes you crave for food that contains a large amount of carbohydrates and fats, and the combination of those two things in particular contributes to weight gain.

Conclusion

Lack of sleep has bad effect on our health. No matter how busy you are, you can always find time for a good sleep. The truth is that often in the evenings we are wasting time doing things that are not useful (watching TV for example). If you couldn’t get enough sleep during the night because of some urgent obligation, then you must find the time to take a nap (20-30 minutes long) during the day.
