I have just followed an American link on Facebook and as I haven't the skill to copy to you I will have to tell you what was written.

To prevent dehydration you need to work out your optimum fluid intake per day.

Take your weight in lbs. Divide by 2. Drink that number of ozs in fluid per day. There are 20fl ozs of water per pint. That's an awful lot of liquid for me!!

There is also emphasis about how energy drinks are likely to trigger arrhythmia due to the caffeine content.

  • I do drink a lot of fluids, but that's because it's damn hot here and humid too. I can tell if I'm getting dehydrated by the colour of my urine and a weird headache. I usually have a rehydration drink if that happens.

  • I think that a lot of people, like me, often limit their intake to reduce the number of times they will need a toilet. There are less and less public toilets in the UK now.

  • I can relate to this!

  • I think dehydration is a factor for me. I drink at least 3 litres of water a day, which at my current weight is just over the required amount. I sometimes have to be careful, as cold water has triggered attacks before. You can't win sometimes :)

  • It's tap water for me- cold liquid is definitely one of my triggers.

  • That is a fraction over 3.5 pints for me, so works out about a large mug of decaffeinated coffee every couple of waking hours. I can manage that.

  • Bear in mind that coffee is a diuretic.......

  • Langara, that made me laugh. I would not like to tell you how much water I would have to drink. Waterlogged just about describes it!

  • Ditto!

  • I have found that staying hydrated is key to helping reduce the number of AF events that I get. Although it is not the only trigger of my AF episodes, I find it very helpful to stay hydrated with water. I do not drink any beverages with caffeine as caffeine can cause dehydration for me. I'm in the U.S. and live in the desert southwest (Arizona). Your average person who lives here is slightly dehydrated because of our extremely dry climate. - KeL

  • Whilst it is an interesting exercise all you really need to do is make sure your wee looks like dry whit wine and not Lucozade . Jennydog since my operation I am more than aware of what you say about public loos but being a man often have to resort to the old carter;s trick.


  • I agree this is the best advice I have seen amongst anything from 8 litres/day to a glass a day. Interestingly, I did read somewhere that when you get older (maybe in your 60's) you forget your thirsty and therefore can more easily get dehydrated.

  • I'm always dehydrated. I find it very difficult to drink large amounts of fluid and this is lifelong. Ever since my grandma kept saying "you don't drink enough" right up until getting Renal colic (kidney stones) 7 years ago and last year.......

    I always wake up thirsty, sometimes In the middle of the night. And I do notice a difference from the usual tiredness, which is usually solved by drinking a couple of pints of fluid!

  • When I was in hospital last week one of the nurses commented on my drinking a lot of water, but it was less than I drink at home, and my urine was darker than usual.

  • I do think that fluid intake needs looking at in hospital. I suppose that the more frequent use of bedpans would be something of a disincentive !

  • I wonder how many people in this group have to take a diuretic for other medical conditions, or have kidney problems? Asks ever, one size doesn't fit all.
