The effect of caffeine on hydration
The authors of the first publications suggest that caffeine intake causes acute diarrhoea, whereas regular intake of caffeine may lead to the development of tolerance and anti-diuretic effects. Various results have been obtained in numerous studies on hydration and its association with caffeine, however, the tendency has been observed that higher doses of caffeination in non-coffee drinkers cause acute Diurosis and lower doses do not. The study involved 50 men who drank coffee and evaluated the effects in several ways. Physical activity, fluid intake and food intake were controlled.
