Stress.
It is something that EVERYONE is affected by. Though no one experiences the same symptoms like another, many are affected similarly. Headaches, rashes, stomach pain, and increased habit participation are signs of stress.
According to the American Psychological Foundation, Stress is linked to the six leading causes of death—heart disease, cancer, lung ailments, accidents, cirrhosis of the liver, and suicide.
Though the impacts on the body can be deadly, there are many easy remedies that can be done in a few minutes and in your own mind such as a mental vacation, or with your body such as stretching.
