Here are the best reasons why you shouldn't sit for several hours a day

When we sit, the blood flow in our legs reduces. It results in blood clots, which worsens varicose veins. The blood circulation normalizes when our leg muscles are working, so, if you have to sit a lot at work, try to stand up every 30 minutes and take a short walk.

As it turns out, our metabolism slows down when we sit too much. Moreover, sedentary lifestyle doesn't require much movements, so we burn fewer calories per day. But do we eat less? It's unlikely, so we gain weight easily.

Even our bones weaken with time if we sit too much. When we are inactive, the bones don't have to support our body, so their density reduces. A disease in which the quality of the bone is deteriorated is called osteoporosis. It increases the risk of a broken bone. Elderly people are often affected by this disease due to the lack of Vitamin D, but today a lot of people who sit too much can have such a problem at a young age.

Inactive muscles also need less insulin. Anyway, when we sit, our pancreas releases the same amount of insulin, which leads to an increased level of this hormone. This can lead to the development of the symptoms of diabetes and other hormonal diseases.

When you move a lot or exercise, your body releases chemicals called endorphins. The endorphins reduce our perception of pain and play an important role in the defensive response of the body to stress. When you have to sit for several hours a day, endorphin deficiency can cause depression. To avoid depression, try to spend more time in the sun and eat foods rich in good fats (olives, avocados, coconut).

Even if you sit at work and get tired of brainwork, your organism simply doesn't understand that. Your body rests when you sit, so you don't get tired physically. Bad posture makes you feel uncomfortable, that's all. That's why when you try to fall asleep at night, your organism simply doesn't need to rest yet.

According to the scientists, people who sit for more than 5 hours a day are 35% more likely to develop heart failure than those who sit less. The thing is that when we are not active enough, our muscles weaken, which negatively affects vascular tone and normal cardiac rhythm.

Sitting turns out to be a non-natural position for your body. It puts more pressure on the spine than standing, moreover, it's even worse when we sit hunched in front of a computer. Intervertebral discs are meant to contract and expand when we move, that's how they absorb all the necessary nutrients and blood. When we sit our spinal discs simply lose their flexibility. It results in lateral curvature and constant back pain. According to the researchers, people who reduced their 10 hours of daily sitting to 1 hour got rid of the back pain in a year.
