Caffeine is good for health in more ways than one, but only when it is taken in moderation. Research shows that high doses of caffeine can have adverse side effects on health, some of which are even dangerous. People who are highly-sensitive to caffeine may even experience negative impacts on taking it in a moderate amount.
Following are 7 negative side effects that accompany excess consumption of caffeine:
1 – Causes anxiety
Caffeine blocks adenosine, the hormone responsible for making you feel tired and encourages in increased release of adrenaline. Adrenaline is the ‘fight or flight’ hormone that is linked to energy. Too much caffeine can overdo these effects resulting in higher stress levels, nervousness, jitteriness, rapid breathing, and anxiety.
2 – Can Be Addictive
Too much caffeine can make you into a caffeine-addict. This is because caffeine’s impact on brain chemicals is like that of drugs like cocaine. A study that was carried out on 213 caffeine lovers showed that people who drink coffee on a daily basis can even experience withdrawal symptoms when they go too long without consuming it. Symptoms include headaches, fatigue, etc.
3 – Causes Digestive Discomfort
Coffee has been shown to be a metabolism-booster. The beverage promotes digestion and bowel movement. Therefore, when you drink copious amounts of coffee, it may lead to loose stools and even diarrhea. Moreover, caffeinated drinks can also worsen GERD in some cases. This is why reducing coffee intake is crucial.
4 – Leads To Insomnia
You must have used coffee as a way to stay up and energized more than once. This is because caffeine can keep you alert. However, when you drink too much coffee, it can cause problems for your sleep. Studies show that too much coffee can shorten your sleeping time. You may even want to avoid drinking coffee late in the day as its impacts can take time to wear off.
5 – May Cause Rhabdomyolysis
Rhabdomyolysis is a condition in which muscle fibers break down and make their way into the bloodstream. This can lead to kidney failure and other health problems. Coffee may cause this condition even though it is very rare of it too. This is another reason you must limit your intake of coffee, particularly if you are sensitive to its effects.
6 – Raises Blood Pressure
Caffeine can also up your blood pressure and, along with it, the risk of stroke and heart disease. This can hamper flow of blood to the brain as well. This negative side effect of caffeine shows up when one drinks too much of the drink or consumes it before exercising. This effect has also been noticed among people who don’t consume coffee all that much.
7 – Causes Fatigue
While moderate doses of caffeine can boost energy markers, too much caffeine can result in fatigue. Studies show that while drinking coffee can enhance alertness and energy after drinking it, the next day it can have an energy-draining effect. Hence, consume only moderate amounts of coffee to save yourself from its rebound effect.
