Latest research shows that baths are not only great for soaking away the stresses of the day, they also play boost your immune system and help skin conditions like eczema.

The New England Journal of Medicine published a study which showed that diabetics who spent just half an hour in a hot tub could reduce their blood sugar levels by around 13 per cent - as the heat dilated their blood vessels, blood-flow improved and the body made better use of its insulin, the hormone that converts blood sugar into energy.

A new book, 48 Hours to a Healthier Life, claims baths can be used as a form of hydrotherapy to keep the body in mint condition.

'I heartily recommend bathing,' says the book's author, Suzi Grant, a member of the British Association of Nutritional Therapists.

'It can prevent colds and viruses, reduce stress, improve sleep, strengthen blood circulation, boost the immune system and detoxify the body.'
