The number of times people do laundry varies from household to household. Some do laundry twice a week, whilst others take a more relaxed approach and do it once every few weeks.
Now a commentator on environmental issues says you should be washing towels every five days. Lucy Siegle said in The Times : “Shake off as much water as you can after showering before patting yourself dry.
"Hang up the towel to dry immediately. That way you don’t need to wash your towel as often — say every five days.”
