9 disadvantages of excess caffeine

When I was little, my mother used to tell me a story about a man who was a strange tea drinker. One day, he went out for a train ride. While travelling on the train, he suddenly remembered to have tea, but there was no tea on the train. The man went crazy when he couldn’t get any tea. The passengers with him looked at him in surprise. When the man couldn’t get any tea, he finally chewed the raw tea leaves and poured hot water into his mouth. That would be a story. However, there are many of us whose brains don’t work without drinking tea and coffee several times a day. The two most popular drinks for people worldwide are tea and coffee. The names of these two drinks are different, but one common ingredient is caffeine. Caffeine affects our mood, metabolism, and mental and physical activities. Research has shown that low to moderate (up to 400 milligrams) caffeine has no negative effects on most people’s bodies. More caffeine than this is harmful to our bodies. However, some people’s physical constitution is such that even after consuming more than a certain amount of caffeine, they do not have much difficulty. It is more a matter of interacting the person’s genes with their digestive capacity. For those whose body do not tolerate caffeine at all or those who drink tea and coffee day and night, the side effects that may occur are-

1. Excessive anxiety

In this short life of ours, we often have various worries. And most of the time, we eat caffeine-like foods to remove this worry. Caffeine generally increases our body’s activity. As a result, our body becomes alert. Caffeine blocks the fatigue factor adenosine in our body, simultaneously expanding the adrenaline hormone and bringing energy to the body. However, one problem is that if the dose of this caffeine is high, it increases the activity of our body’s hormones and turns into anxiety and nervousness. Sensitive people may be at risk of panic attacks if they consume 1,000 milligrams or more of caffeine per day.

2. Insomnia

One of the reasons for drinking tea and coffee is to relieve insomnia. The caffeine in this tea and coffee keeps people awake. The feeling of sleepiness is removed, which makes us feel more comfortable working. However, excess caffeine is one of the reasons for our insomnia. Studies show that excessive caffeine intake does not lead to complete sleep. It also takes a long time to fall asleep. So, if you want to avoid the problem of insomnia, keep an eye on the amount and when you are drinking it before drinking tea and coffee.

3. Digestive problems

One of the habits of most of us is to drink tea and coffee on an empty stomach in the morning. Without drinking it, our day does not go well. But we do not realize how much damage we do to the body due to this habit. The habit of drinking tea and coffee on an empty stomach in the morning often causes gastric problems. Many people may blame caffeine for this and habitually drink decaffeinated coffee. However, decaffeinated coffee can also cause gastric problems. Apart from this, many people may even have diarrhoea due to drinking too much coffee in the morning.

4. Muscle damage

Excessive caffeine intake can cause the body’s muscle fibres to break down little by little and mix with the blood. In medical terms, this is called rhabdomyolysis. Trauma, infection, muscle strain, drug use, and bite of something poisonous can cause rhabdomyolysis. However, the chances of this happening due to caffeine intake are very low, but it can occur in many cases, especially if someone becomes addicted to excessive tea and coffee.

5. Addiction

Drinking excess tea and coffee often becomes addictive. Studies have shown that excess caffeine acts on our brain much like cocaine or amphetamine drugs. However, this addiction is different for each person, depending on their mental and physical condition. Caffeine addiction is not as severe or life-threatening as drugs, but people addicted to excessive caffeine can do strange things.

6. High blood pressure

High blood pressure has become one of the most common diseases. High blood pressure is one of the causes of heart disease and stroke. Caffeine does not directly play a role in heart disease or stroke. However, its stimulating effect increases blood pressure in the veins and arteries. High blood pressure disrupts the orderly movement of blood, obstructing blood flow to the heart and brain and creating situations like heart attack or stroke. Usually, those who cannot tolerate caffeine in their blood pressure should understand their blood pressure before consuming it in excess. They should drink tea and coffee with an understanding of the amount and time.

7. Increased heart rate

Excess caffeine (due to its stimulating effect) can increase heart rate. Young people who drink energy drinks containing excess caffeine are usually more likely to experience alternating fluctuations in heart rate. So, if your heart rate seems different than normal, you should reduce your caffeine intake.

8. Fatigue

We drink tea and coffee to relieve our fatigue. We also drink it to increase energy. However, excessive caffeine intake can have the opposite effect. A study has shown that although caffeinated drinks boost mental energy, alertness, and mood for a few hours, they make our body more tired and sluggish for the next hour or day. So, drinking in small amounts without overdoing it is good for the body.

9. Frequent use of the bathroom

Caffeine not only increases the stimulation of our brain but also puts pressure on the urinary bladder. You will notice that many people run to the bathroom immediately after drinking tea and coffee.
Caffeine in low or tolerable doses is best for the body. So, if you want to get the benefits of caffeine in your favourite tea and coffee, you must take care of your physical condition and sleep.
