Sleep is important for our health. But how important is it really? We take a closer look at what happens to weight, mood and the immune system when you are not getting enough sleep. Who knows, tonight you might go to bed already at 9.30 pm 😉
…… your memory
Sleep plays an important role in your ability to store knowledge and remember. It is during the deep REM sleep that the brain seriously processes and acquires new knowledge – especially if it is complex and emotional. If you sleep too little, you will not get the opportunity for this, and new knowledge may be lost.
… Your mood
You may experience large mood swings. Maybe you get more tense and worried. Your risk of developing depression also increases significantly compared to people who get enough sleep. And since both anxiety and depression make it harder to sleep, you can get into a vicious circle.
… Your judgment
You find it difficult to interpret situations correctly and thus act in the most appropriate way. At the same time, it means that you are rarely aware of how wrong things are. You feel sharp, but it’s just a reflection of your so-so judgment.
… Your sex drive
In both men and women, the interest and desire for sex decreases. The lack of night sleep consumes the energy and makes you both tired and tense, without lust for much sex.
… Your ability to solve tasks
You find it difficult to concentrate. Your ability to solve problems and draw conclusions also deteriorates. In addition, a tired body and brain are prone to switch to autopilot. It makes you less creative when you have to solve tasks. At the same time, you find it harder to focus and become less efficient. Therefore, you are probably making far more mistakes than usual.
People who sleep less than six hours a night have a significantly higher risk of becoming overweight than those who get 7-9 hours of sleep. When we sleep for a shorter time, the production of the hormone leptin, which regulates our appetite, is reduced. At the same time, the production of the hormone ghrelin increases, which stimulates our hunger. And, as if that were not bad enough in itself, it is especially high-calorie foods with fats and carbohydrates that we crave. Your body will lack energy and strength when the muscles have not been allowed to rest. You also react more slowly than usual. This applies both in relation to sports and everyday physical tasks.
… Your stress level
The nervous system only works optimally if you get a good, long night’s sleep. If you sleep too little, the amount of stress hormones will increase rather than disappear. Among other things, it can result in high blood pressure.
… Your appearance
Your skin becomes itchy, and you get more lines and dark circles under the eyes. Sleep is necessary to build up both skin and tissues. So it is not a coincidence that it is called “beauty sleep.”
…… your immune system
Sleep is important for how and how effectively the immune system responds to infections. If you get too little, the t-cells weaken, which increases your risk of catching a cold and getting the flu. It also makes it harder for you to get back on top and normal levels.
… Your general health
If you do not get enough sleep for a long period of time, it can be dangerous for your health. Sleep has an influence on the autonomic nervous system, which helps regulate blood pressure and heart rate. During normal sleep, blood pressure and heart rate fall. If you do not sleep enough, or your sleep is interrupted many times during the night, the brain is activated more, and both blood pressure and heart rate rise instead of falling to rest levels. Researchers believe this may be part of the reason why people with sleep disorders are more likely to have heart problems than people who sleep longer and more regularly. Too little sleep also damages the body’s ability to regulate blood sugar, and it, therefore, increases your risk of developing diabetes.
