Do pores on the skin need to breathe?

Pores on the skin represent openings of hair follicles and sweat ducts.  These pores do not ‘breathe’ in the usual sense – our lungs take care of that need.  Yet, it can help to keep your pores open.  Sweat gland openings can become obstructed – for example, by wearing skin tight clothing when we exercise.  This can result in an itchy heat rash, or miliaria,  Hence, it is advisable to avoid overdressing when it is hot, and to remove sweaty clothing and shower as soon as possible after exercising.  The widespread plugging of sweat (or ‘eccrine’) glands can result in heat intolerance – with the risk of heat stroke.  Individuals who have one of the skin disorders called ichthyosis,  where the outermost layer of skin, the stratum corneum, is too thick over most or all of their body, often experience overheating because their sweat ducts are obstructed by scales.

Similarly, when the pores of sebaceous glands on the face, chest and back become plugged with sebum and keratinous debri, we develop blackheads.  These are often an early sign of acne and an indication that it’s time for a visit to our dermatologist.  While blackheads are not caused by too infrequent face washing, they can be produced by some of the products we put on our skin, such as oily cosmetics.  Look for the label “non-comedogenic” on cosmetic products, which will indicate a safer product to use.  And avoid oily scalp pomades.pores
