MORE THINGS I DIDN’T KNOW ABOUT HYDRATION
- Body fat contains only 20% water and lean tissue 70%, so a thin person’s body has a higher percentage of water than a fat person.
- 75% of our fluid intake occurs while eating.
- Drinks provide 10% of the energy intake of adults in the UK – mainly from alcohol.
- Sweat loss in team and endurance sports can be 1-2 litres per hour. 1.4 litres equates to a 2% loss for an average 70kg male and this is the established level for decreased performance. One should drink 50% more than this to rehydrate properly.
- A mug of tea contains more caffeine than a can of cola, both having less than a can of energy drink or a mug of coffee.
- Apart from very strong coffees, the fluid in drinks containing caffeine compensates for their short term diuretic effect.
- Wines and spirits have a net diuretic effect, whereas beer and cider do not.
