Bathing every day could increase people's risk of infections, experts warn.

Showering excessively can reduce skin hydration, causing it to become dry and cracked, which allows germs to enter, according to infectious-disease expert Dr Elaine Larson from Columbia University.

Dr Brandon Mitchell, assistant professor of dermatology at George Washington University, adds washing strips the skin of its natural oils, which can disrupt 'good' bacteria that supports people's immune systems.

According to Dr Mitchell, bathing just once or twice a week is usually sufficient for most, adding: "A daily shower isn’t necessary."
