20 Surprising Things That Are Actually Damaging Your Kidneys

4. Caffeine

Caffeine is a natural substance that makes you feel more awake and alert. It can be found in coffee, tea, cocoa, and chocolate. Although coffee is a popular beverage that many people consume every day, it has bad side effects.

Caffeine will speed up the central nervous system and raise your body temperature. If you consume too much caffeine, your blood pressure will increase, and you may have headaches and insomnia. In addition, your kidneys will become dehydrated and have to tolerate more pressure.

Therefore, experts recommend that an adult have no more than 200-300 milligrams of caffeine each day. And please remember that caffeine is contained in many different foods and drinks, not just coffee.
