How much coffee a person can and should drink per day depends on various factors. Your age and body weight play a big role here. And you should also keep in mind that there are other sources of energy besides coffee that can keep you alert and fresh.
Thanks to coffee, we can overcome our tiredness so that we are more efficient and productive during work. And coffee in the morning in particular helps us start the day better and easier. But how much coffee should we drink a day?
Too much caffeine is unhealthy
Basically, caffeine has a positive effect on our body. However, this positive effect can be reversed and damage your health if you consume too much caffeine.
An overdose of this alkaloid can lead to some dangerous symptoms, such as:
- Muscle tremors
- Cardiac arrhythmias
While you would have to consume a very significant amount of caffeine to get into this situation, the possibility that you could even die from a caffeine overdose cannot be ruled out.
The effects ultimately depend on your physical condition.
How Much Caffeine is in a Cup of Coffee?
It is not easy to make a blanket statement about how much caffeine is in a cup of coffee. The caffeine content depends on the quantity and quality of the beans used to make the coffee.
It is estimated that a cup of coffee contains between 50 and 400 milligrams of caffeine. The concentration also depends on how much water there is in the coffee. So the relationship between coffee and water is crucial.
It is also known that 10 grams of caffeine can be fatal to a person.
So you would have to drink 25 cups of a very strong coffee in a very short time to get that amount of caffeine. This amount would then be fatal to the human body.
Body weight and toxic dose
The toxic dose of caffeine also depends on body weight. The heavier a person is, the higher this dose will be. Because of this, we now ask ourselves what amount of caffeine could actually do you serious harm.
- Take, for example, a person who weighs up to 50 kilograms. If that person ingests more than 7.5 grams of caffeine, it could have serious consequences. With this amount, there would also be a risk of dying from it.
- If a person weighs more than 78 kilograms, the potentially lethal dose of caffeine is 12 grams, and research has shown that consuming more than 90 cups of espresso can lead to sudden death.
These numbers apply to adults. In children, these values are much lower because they have a much faster metabolism. Therefore, children should of course consume significantly less caffeine.
- 35 milligrams of caffeine per kilogram of body weight would lead to a serious overdose in children .
- This amount corresponds to the amount of caffeine that an adult would normally consume in one cup of coffee.
How Much Coffee is Healthy?
The recommended daily coffee consumption is currently a maximum of 4 cups. This amount is regarded as the maximum limit for healthy daily coffee consumption and should therefore not be exceeded. Nevertheless, there are definitely people who exceed this amount extremely.
It should also be noted that every body reacts to different substances in a very individual and unique way. This means that every person has a personal tolerance threshold for certain substances.
How much coffee you can tolerate without harming your health therefore varies greatly from person to person and depends on various factors.
However, if you exceed your personal tolerance threshold for caffeine, then this could result in the following symptoms, among others:
- sleep disorders
- stomach pain
- Accelerated pulse
Avoid too much coffee
Basically, drinking coffee and other caffeinated beverages in moderation is beneficial to health. Having a cup of coffee after a meal can help regulate your blood pressure. However, you shouldn’t overdo your coffee consumption, because consuming too much caffeine can certainly cause health problems.
In all likelihood, caffeine is the most widely consumed legal drug in the world. You should also keep in mind that caffeine is a psychotropic substance. For this reason, if you consume a certain amount of coffee or caffeinated drinks on a regular basis, you may become addicted.
Even normal, regular coffee consumption means that you can develop withdrawal symptoms if you do not consume caffeine for 24 hours.
This means that, for example, you can get muscle pain and headaches, feel physically tired or have difficulty concentrating.
For this reason, once you haven’t had enough caffeine, it is actually the result of regular coffee consumption that you feel sleepy and inattentive.
In summary, we can say that coffee will generally not have any negative consequences for your body if you do not drink too much of it.
Coffee definitely has a positive influence on your performance. But if you consume too much of it, this positive effect can turn into a negative one.
