1. Anxiety

Caffeine is known to increase alertness. It works by blocking the effects of adenosine, a brain chemical that makes you feel tired. At the same time, it activates the release of adrenaline, a hormone involved in boosting energy .

However, at higher doses, these effects may become more prominent, leading to anxiety and stress. In fact, caffeine anxiety disorder is one of the four caffeine-related syndromes listed in the Handbook for Diagnosis and Statistics of Psychiatric Disorders (DSM), published by the American Psychiatric Association. .

The report from cambridge.org shows that daily consumption that is too high of 1,000 mg- 1,500mg or more per day has been reported to cause anxiety, while even moderate amounts may lead to similar effects in sensitive individuals. colds with caffeine.

If you find that you’re constantly feeling anxious or restless, you should consider your caffeine intake and cut down on it. Although low to moderate doses of caffeine can increase alertness, larger amounts can lead to anxiety or irritability.

2. Insomnia

Caffeine’s ability to keep people awake is appreciated.

On the other hand, too much caffeine can make it difficult to get enough sleep.

Studies have found that higher caffeine intake appears to increase the time it takes to fall asleep. At the same time can reduce the total sleep time, especially in the elderly. In contrast, low or moderate caffeine intake does not seem to have much effect on sleep in people considered to be “good at night” or even those who self-report insomnia.

3. Digestive problems

Many people find that a cup of coffee in the morning will help the digestive system work better. Coffee’s effects are thought to be due to the release of gastrin, a hormone that the stomach produces to speed up activity in the colon.

What’s more, decaffeinated coffee has been shown to produce similar reactions. However, caffeine itself also seems to stimulate bowel movements, contractions that move food through the body’s digestive tract.

4. Muscle breakdown

Rhabdomyolysis is a very serious condition in which damaged muscle fibers enter the bloodstream, leading to kidney failure and other problems. Common causes of rhabdomyolysis include trauma, infection, drug abuse, muscle tension, and being bitten by venomous snakes or insects.

Additionally, there have been some reports of rhabdomyolysis associated with excessive caffeine intake, although this is relatively rare. To reduce your risk of rhabdomyolysis, it’s best to limit your intake to about 250 mg of caffeine per day, unless you are used to consuming more.

5. Addictive

Despite all the health benefits of caffeine, there’s no denying that it can be a habit. A detailed review found that although caffeine activates certain brain chemicals similar to how cocaine and amphetamine do, caffeine is not as addictive as these drugs.

6. High blood pressure

Overall, caffeine does not appear to increase the risk of heart disease or stroke in most people. However, it has been shown to increase blood pressure in a number of studies due to its stimulant effects on the nervous system. High blood pressure is a risk factor for heart attack and stroke because it can damage the arteries over time, limiting blood flow to your heart and brain.

Coffee, tea and other caffeinated beverages are known to boost energy levels. However, they can also have the opposite effect, leading to fatigue returning after caffeine is gone

8. Urinate often

Excessive urination is a common side effect of high caffeine intake due to caffeine’s stimulatory effects on the bladder. You may find that you need to urinate more often when you drink more coffee or tea than usual.
