Staying well-hydrated 'may slow down ageing and prolong life'

Using health data gathered from 11,255 adults over 30 years, researchers analysed links between serum sodium levels — which go up when fluid intake goes down — and various indicators of health.

Adults who stay well-hydrated appear to live longer and develop fewer chronic conditions, a study suggests.

The peer-reviewed findings of the National Institutes of Health (NIH), a US medical research agency, were published in the eBioMedicine journal on Monday.
