According to the American Psychology Association, high levels of cortisol and other stress hormones can result in a poor immune response. When combined with irregular skin care habits, which are common during times of high stress, tiny breaks in the skin are more susceptible to infection from the bacteria that causes boils.

Stress management techniques can help improve the overall appearance of the skin and boost the body's immune response.
