Stress and its effect on the body.

4. Rash. Stress can weaken your immune system and lead to intestinal dysbiosis. Subsequently, it manifests itself in the form of redness and a rash on the skin. Stress also causes and exacerbates some autoimmune diseases such as psoriasis, eczema and dermatitis. 5. Wrinkles. Stress causes changes in the proteins of the skin and reduces its elasticity. During stress, we constantly frown, which is why characteristic creases quickly form. 6. Gray hair and hair loss. Cells called melanocytes produce the pigment melanin, which gives hair its color. Stress-induced sympathetic nerve activity can lead to the disappearance of the stem cells that create melanocytes. Chronic stress can also disrupt the hair growth cycle and lead to hair loss.
