There could be a simple solution to stop you feeling fatigued all the time
Find yourself feeling tired all the time? There might be a very simple explanation.
A new survey by British GPs found that one in five people who call for a consultation complain about being fatigued - and a major factor is because people aren't drinking enough water.
The official guidelines say you should drink between 1.6 and two litres per day, but most people only drink one glass or less, leaving them drowsy and dehydrated.
Dr Roger Henderson, author of 100 Ways to live to 100, says: "There are, of course, several reasons that could be causing this but a surprisingly common cause is that they are dehydrated.
"Many of my patients do not drink enough fluid each day and only believe they are dehydrated when they start to feel thirsty."
So, it could be pretty easy to find a little more energy during the day - just try and hit that two litre mark and you'll feel more awake in no time.
