Whether you consume tea, coffee, sodas, energy drinks, or chocolate, you’re consuming some form of caffeine. It has a small number of benefits but it’s the excess use of caffeine that is an issue, as this compound can be addictive. Caffeine doesn’t even provide true energy. It is merely a stimulant. Still, there are many who rely on it every day to get them going. Here are the side effects of too much caffeine:
Caffeine encourages dependency
Caffeine suppresses a chemical called adenosine, which is secreted by the brain to relax the body. Suppression of this compound by caffeine affects the body by making it feel a tense surge of energy. While this surge of energy is truly stimulating, the threshold of stimulation continues to rise, making the brain require increasing levels of caffeine to simulate the same effect. This creates dependency on users who require caffeine on a daily basis to get moving.
It promotes dehydration
Another negative effect of caffeine is dehydration. Caffeine acts as a diuretic, which may be a benefit to individuals dealing with bloating. For others, however, caffeinated drinks are among the biggest contributors to dehydration—despite a high volume of liquid consumption with these beverages. Dehydrated cells have difficulty absorbing nutrients, and they also have problems eliminating waste.
It slows digestion
Perhaps the most negative impact caffeine has on the body occurs in the digestive system. It blocks the absorption of magnesium, a key mineral that is essential to the colon’s regulation of normal, healthy bowel movements. Coffee itself compounds the problem by acting as a laxative, causing the bowels to move prior to the absorption of water and mineral nutrients. This reinforces body dehydration and malnourishment. Coffee also increases stomach acid levels, and higher acid levels can cause permanent damage to the intestinal lining.
Caffeine’s ability to help people stay awake is one of its most prized qualities. On the other hand, too much caffeine can make it difficult to get enough restorative sleep. Studies have found that higher caffeine intake appears to increase the amount of time it takes to fall asleep. By contrast, low or moderate amounts of caffeine don’t seem to affect sleep very much in people considered “good sleepers,” or even those with self-reported insomnia.
High blood pressure
Overall, caffeine doesn’t seem to increase the risk of heart disease or stroke in most people. However, it has been shown to raise blood pressure in several studies due to its stimulatory effect on the nervous system. Elevated blood pressure is a risk factor for heart attack and stroke because it may damage arteries over time, restricting the flow of blood to your heart and brain. Fortunately, caffeine’s effect on blood pressure seems to be temporary. Also, it seems to have the strongest impact on people who aren’t used to consuming it.
Rapid heart rate
The stimulatory effects of high caffeine intake may cause your heart to beat faster. It may also lead to altered heartbeat rhythm, called atrial fibrillation, which has been reported in young people who consumed energy drinks containing extremely high doses of caffeine.
