does alcohol contribute to psoriasis
Alcohol may directly affect psoriasis by aggravating inflammation and drying out the skin. It may have an indirect affect by reducing the number of vitamins absorbed, which can affect immune function. Deficiencies in zinc and vitamin C are common in heavy drinking, and these can affect wound healing. Drinking a lot of alcohol also reduces sleep quality, and because itâs high in calories, can contribute to excess weight â and both high levels of body fat and a lack of sleep can aggravate inflammation in the body15.
