Doctor who runs shower for 20 minutes after holidays says ‘it’ll save your life’

A microbiologist has shared a simple ritual he does every time he comes back from holiday.

Dr Tom Makin leaves his shower running for 20 minutes without getting into it, and after it's turned off he doesn't go back in the bathroom for another 20 minutes.

The process, he says, is a measure to prevent lethal bacteria causing life-threatening conditions.

Dr Makin says that in the time a person is on holiday, stagnant water in your shower head could turn toxic.

This means people are at greater risk of inhaling bacteria called legionella.
