Top athletes will tell you, you need to start hydrating DAYS before an event. For the average Joe… Maybe just the day before. Your body needs water. Humans are 65% water. You should be hydration all day long. That’s not just 9-5. That’s ALL day. Start your day with some WATER to go with your coffee, not just IN your coffee. Caffeine is a diuretic.
Tending to increase the discharge of urine.
A substance or drug that tends to increase the discharge of urine.
Large quantities of coffee ,tea, soda, and other sources of caffeine can cause your body to lose water. The caffeine in one soda is not enough to negate all the water in that soda, but excessive quantities are likely to decrease the water absorbed by your body. Energy drinks can result in a net loss of water. High doses of vitamin C can have a similar effect. More recent studies have shown that you’d need to intake pretty large doses for the diuretic effect to be much more than negligible but that the effect can also be somewhat cumulative.
Feeling run down all the time? Dehydration is a leading cause of fatigue. So next time you’re feeling the afternoon lazies… Check your water consumption for the day. I bet you’re thirsty now. Remember, it’s not just about the water you drink today. Hydration starts yesterday!
