Why does drinking coffee cause anxiety and fatigue?

introduction

Coffee is a must-have drink for many people every morning. It not only refreshes the mind, but also has a delicious taste. However, some people experience palpitations and fatigue after drinking coffee. This situation is confusing. Why does drinking coffee cause palpitations and fatigue? This article will focus on this issue.

Effects of Caffeine on the Body

First, we need to understand the effects of caffeine on the body. Caffeine is a stimulant that can stimulate the central nervous system and increase alertness. When we drink a cup of strong and mellow coffee, the caffeine contained in it is quickly absorbed into the blood circulation system and transmitted to the brain.

Causes of panic feeling

However, not everyone can benefit from it. Some people experience discomfort such as palpitations and fatigue when they consume too much or are sensitive to caffeine. This is mainly due to the following reasons:

1. The stimulating effect of caffeine

Caffeine has the effect of stimulating the central nervous system, which can increase heart rate and blood pressure. When we consume too much caffeine, the central nervous system will be overstimulated, resulting in symptoms such as faster heartbeat and vasoconstriction. These physiological reactions can make people feel flustered and uneasy.

2. Caffeine’s diuretic effect

Caffeine also has a diuretic effect, which can promote urination and increase urine volume. This means that after consuming a large amount of caffeine, the body will lose more water and electrolytes. If you do not replenish enough water and nutrients in time, you are prone to symptoms such as fatigue and dizziness.

Individual differences and tolerance

In addition to the above two reasons, individual differences are also one of the important reasons why drinking coffee can cause palpitations and fatigue. Everyone has different sensitivity to caffeine, and it is common to have different reactions to the same dose. Some people may experience discomfort symptoms after consuming only a small amount of caffeine, while others can tolerate higher doses of caffeine without obvious reactions.

Solution

If you are a person who is prone to symptoms of palpitations and fatigue, the following methods may help you:

1. Control your intake

First of all, you should pay attention to controlling your caffeine intake. Depending on individual differences and tolerance, everyone has different sensitivity to caffeine. If you find that drinking a cup of normal strength coffee will cause panic, fatigue and other reactions, you can try to reduce the amount you drink or choose low-caffeine drinks.

2. Gradually quit

If you realize that you are very sensitive to caffeine and this situation is causing trouble in your life, you can consider gradually quitting it. You can try to reduce the number of cups you drink per day by half at first, and gradually reduce the dosage until you quit completely. This will allow your body to gradually adapt to the state of not having caffeine.

3. Replenish water and nutrition

If you have consumed too much caffeine and have symptoms such as palpitations and fatigue, it is very important to replenish water and nutrients in time. Drinking enough water can help dilute the excess caffeine in the blood and promote its excretion. In addition, consuming foods rich in nutrients such as vitamin B and C can also help relieve fatigue.

in conclusion

Coffee-induced palpitations and fatigue are due to individual differences and caffeine's stimulating effects on the central nervous system and kidneys. Controlling intake, gradually quitting, and replenishing water and nutrition are all effective ways to relieve this uncomfortable symptom. However, please remember that everyone has different levels of sensitivity to caffeine. If you cannot tolerate palpitations and fatigue, please seek medical attention and professional advice in a timely manner.
