When we go swimming and spend extended time in water, it is not clear whether the little bugs living on our skin, such as Demodex mites, suffocate and die. Demodex mites live inside hair follicles and pores, feeding on sebum, the oily substance our skin produces[1]. They are difficult to remove by washing, as they reside deep within the pores[1]. While some insects can survive underwater for short durations[2], there is no specific information available on whether Demodex mites can survive extended periods underwater.

However, it is important to note that spending time in chlorinated water, such as in swimming pools, may have some effect on the mites. Chlorine is a disinfectant that can kill various microorganisms, but there is no direct evidence to confirm its effectiveness against Demodex mites specifically.

In conclusion, it is uncertain whether spending extended time in water, especially chlorinated water, will cause the little bugs living on our skin to suffocate and die. However, maintaining good hygiene and washing your face regularly can help manage the population of these mites on your skin[3].
