This Should Wake You Up: Caffeine's Not Dehydrating

This Should Wake You Up: Caffeine's Not Dehydrating

It seems like "coffee" has a new PR agent. This simple drink, blamed for many illnesses and diseases in the past, is starting to get a healthful reputation.

The latest good news about java - caffeine doesn't promote dehydration. Add to that the fact that caffeine might actually help you exercise longer and you have a double shot of good news.

After reviewing more than a dozen studies, Lawrence Armstrong, of the Human Performance Laboratory, concluded that moderate caffeine consumption (up to about 500 milligrams a day) did not adversely impact exercise. While caffeine is a mild diuretic, meaning it briefly increases urine production, moderate amounts are not enough to interfere with a workout by causing excessive fluid loss. Dehydration is about the balance of fluid intake and fluid loss.

These previous studies also suggest that caffeine may even boost performance during activities lasting longer than 30 minutes by enabling exercisers to work out longer. Although the reasons for this effect are still unclear, but one theory is that caffeine helps the body turn fat into fuel for longer workouts.

This news doesn't not mean you should fill your camelbak or water bottle with an iced latte. If you are sweating you need to pay attention to the amount of fluids you have lost and replace them as needed. This does mean, however, that you can enjoy a cup of joe before your morning workout.

WAHOO! I cannot live without Caffeine that is for sure! I MUST drink at least 90 mg. of the stuff every morning, but I usually drink a lot more than that. I have recently been introduced to this new stuff called DIET TURBO TEA: everyone google this because it tastes just like ICED TEA! It is amazing!!! Im starting to get addicted which is bad because it is not widely known so when I go back home for breaks (cause I am in college) I dont think it will be around there. I am trying to cut out diet soda from my life because my bones are very weak and this stuff is a life saver!!

Gee, you think that might benefit from making people worry about caffeine in coffee? Hmmm. And Nocaf4me appears to only make comments in articles about caffeine. Hmm indeed. I'm getting tired of so much paranoid hype from different food/anti-food groups.

Yeaaaaahhhh! I always feel kind of bad when I drink coffee because I feel like I'll regret it and get all dehydrated and just have to drink more, but now I don't have to!

I agree with Nocaf4me, after researching the effects of coffee on the body, I have stopped drinking it completely. This has really helped my diet and exercise program. The main thing that convinced me was that caffeine causes your body to mismanage it's sugar levels, and can contribute to sugar cravings (therefore resulting in snacking etc.) Sugar is also addictive so it seems the two (for some people, not everyone) can be intertwined. I am sure there are many people who can drink coffee and have no negative benefits, but for me this wasn't the case. After 30 days of not drinking coffee, my sugar cravings have decreased significantly.

This is nice to hear, but NoCaf4Me makes some good points. I think moderate amounts are probably OK, but if it's the only thing getting you through a workout or keeping you awake at work, that's probably NOT a good thing - even if it isn't dehydrating. I try to limit myself to 1 cup of joe in the morning and maybe a tea if I need a pick-me-up in the afternoon. One interesting thing I heard about coffee - that's where Americans get most of their antioxidants in a day.
