8) Premature Aging
You may not think to associate overworking with biophysiological age. But not taking vacation time can lead to more rapid aging of your body. When you work non-stop, you tend to become stressed. While the mental aspect of this is bad enough, the physical symptoms of stress are as well. Stress raises the hormone levels in your body, including cortisol. Elevated cortisol levels can cause artery hardening, muscle loss, collagen loss, and can also weaken the immune system. These symptoms can lead to further health issues. Therefore, it is not healthy to let your stress hormone levels stay high. Taking vacations that allow your body to relax will make you happier and healthier. It may even give you more years of life to enjoy than being constantly overworked does.
