Most individuals shower in the morning or before night to freshen up.
One hygiene expert says daily washing is "not important" and we do it to be "socially acceptable."
Bathing regularly prevents "nasty" body odour, says Professor Sally Bloomfield of the London School of Hygiene and Tropical Medicine.
The health guru who approved the government's hand washing effort during the Covid outbreak said washing isn't required.
Too much washing can deplete the body of its self-regulating microbiota, which controls skin oil levels.
She added, "We don't need to bathe and shower every day." Bathing and showering are unnecessary.
