If we happen to drink too much coffee over the short period, we may experience mental as well as physical symptoms such as: restlessness, dizziness, anxiety, irritability, insomnia, tremors, fast heart beat, and upset stomach.

Experiencing all or any of these symptoms after drinking coffee may indicate that we are sensitive to caffeine and therefore, should consider to cut down on its consumption or even avoid caffeine altogether.

While it is possible to die from the caffeine overdose, this can't happen from drinking coffee alone. A person would've to drink more than 23.7 liters or 100 cups of coffee in a single day.

However, there still exist a few rare cases of people who have died after taking caffeine supplements. In other words, we shouldn't consume too much caffeine as it may cause a variety of unpleasant symptoms which are mostly related to our brain as well as digestive system.

Different People Tolerate Different Amounts

Caffeine affects people in many different ways. It's worth mentioning that many genes have been discovered which affect people’s sensitivity to this powerful stimulant.

These genes also affect the enzymes which break down caffeine in our liver alongside the receptors in our brain which are affected by caffeine.

Moreover, the caffeine effects on sleep are genetically determined as some people drink coffee and then go to sleep immediately while there are others who are kept awake throughout the whole night.

So depending on a person's genetic makeup, we may tolerate a lot or very little of caffeine. Most people are usually somewhere in the middle. Additionally, our acquired tolerance plays a very important role as well. Those people who drink coffee every day are much more tolerable of caffeine than those who drink it rarely.

It's also important to note that some medical conditions may affect sensitivity to caffeine. For example, if a person has anxiety, panic disorder, high blood pressure, heart arrhythmia, diabetes, or other medical conditions, chances are high that they'll tolerate less caffeine. However, in order to discover our caffeine tolerance, consultation with a medical provider is much better than doing experiments on our own.

In other words, our sensitivity to caffeine remains highly variable, depending on genes as well as receptors for caffeine in our brain.

4 cups of coffee

Evidence indicates that just 4-5 cups of coffee each day may function as the optimal amount since this exact amount is linked to a lower risk of several common diseases as well as the lowest risk of premature death.

However, this doesn’t mean that any of us are now suddenly obliged to have a cup of coffee (or even cups) each day.

People who have certain medical conditions, don't like this beverage, or are simply caffeine-sensitive should definitely avoid it. What’s more, did you know that coffee tends to give us anxiety or sleep problems? So if you've been suffering from any of them as of lately, reducing or even eliminating caffeine intake altogether can help you in resolving the issues.

Furthermore, we can easily negate a variety of benefits coffee provides by adding sugar or some other unhealthy and high-calorie ingredients to it. Yet, it is still possible to try optimizing your coffee for successfully obtaining the maximum benefits.

Caffeine During Pregnancy

In pregnant women, caffeine is able to cross the placenta, reaching the fetus. However, the fetus has problems with metabolizing caffeine.

Some studies have even linked high caffeine intake during pregnancy with the increased risk of stillbirth, miscarriage, premature delivery as well as the lower birth weight. Generally, it is recommended that pregnant women should limit their intake to hundred or two hundred mg of caffeine each day which is about 1-2 cups or 240-475 ml of coffee.

However, many experts still recommend avoiding coffee altogether during pregnancy. So if you are a pregnant woman who wants to ensure the safety of both you and a fetus, this will be a smart choice.

Too Many Answers

For people who enjoy coffee, there is no need to worry as there’s very little evidence supporting the harmful effects of coffee and too much evidence supporting its benefits.

And while 4-5 cups each day can be optimal, many people are able to tolerate more than that amount without any problems which means that for people like us who enjoy drinking a lot of coffee as well as don’t experience any side effects, there’s no need or reason to stop drinking it.
