Stress and Acne ...... whether related to each other?
There has been a long debate about stress-related acne in health circles. Until a couple of years ago, the medical field was divided on the issue of whether stress causes acne, but recently there has been many clinical studies which show that stress can worsen acne.
One such study was conducted by the Stanford University School of Medicine in 2002. Although it was a small study, involving just 22 students suffering from acne, the professors involved in the study conclusively proved that the exam stress worsened acne in these students. According to researchers, their findings indicated that "Subjects who had the greatest increases in stress during examination periods also had the greatest exacerbation in acne severity."
They also noted that worsening of diet during stressful period contributed significantly in flare-ups of acne in these students.
Stress causes worsening of acne in two ways. First, by stimulating adrenal glands to produce more hormones and secondly, by slowing down the healing process.
Adrenal glands, which are located above the kidneys, secrete norepinephrine and epinephrine under stress and adrenal cortex secretes male hormones. These male hormones are well known for stimulating the sebaceous gland to secrete more sebum, which ultimately results in the formation of acne.
It has also been established that psychological stress can decrease the wound healing capacity of immune systems up to 40%. This factor doubles the impact of stress on acne.
Stress not only affects acne flare-up, in general it worsens the overall skin condition. It induces the adrenal glands into overproduction of cortisol, a steroid, which in turn makes sebaceous glands produce more oil and make skin extra oily. This the reason why in stressful periods, people experiencing an increase in acne get more inflamed, pus-filled papules than simple whiteheads or blackheads.
