Facts and Stats on Caffeine Effects
This section explores the effects of the world’s favorite beverage to start the day with. Find out everything about recommended daily doses, the consequences of excessive consumption, and many other exciting facts about caffeine and the ways it affects people.
Let’s have a look.
1. The recommended daily dose of caffeine is 400mg.
According to statistics on caffeine, this recommended dose is equivalent to four regular cups of coffee, and it’s only suitable for healthy adults. Bear in mind that staying within this mark will result in a caffeine amount that is likely safe for a regular healthy adult, which still doesn’t make it 100% safe.
2. Drinking more than 4 cups of coffee daily for a long period might be unsafe.
This goes in line with the last fact of under 400mg of caffeine daily being safe. Anything above it increases your chances of experiencing some of the many coffee side effects, like nervousness, restlessness, stomach irritations, nausea, vomiting, insomnia, increased heart rate, and more. Larger doses might even lead to anxiety, headaches, chest pain, and ringing in the ears. In the end, very high doses for a prolonged period can lead to irregular heartbeat and even death.
3. People taking excessive amounts of caffeine daily are likely to be in poor shape and start smoking.
The results come from a Mayo Clinic partnered study in which the participants have attested to these facts themselves. The study reveals that there exist more than just the generally accepted negative effects of caffeine.
4. Coffee pills and powders are the number one cause of caffeine poisoning deaths.

Caffeine rarely causes death. However, excessive intake may lead to fatal consequences.
Let’s go through some of the most important caffeine powder and caffeine drug facts, as they’re the leading cause of caffeine deaths due to their high caffeine content.
Caffeine supplements usually contain 100–200 mg per serving. Taking multiple tablets often leads to overdose and caffeine toxicity.
On the other hand, only a teaspoon of pure caffeine powder provides 3,200 mg of caffeine—exceeding the safe 400 mg daily dose of caffeine for adults by far.
5. Coffee drinkers often report having irritated stomachs and indigestion after drinking caffeinated beverages.
The participants who were in the studies that determined these adverse effects usually had them after drinking caffeinated drinks on an empty stomach. This means that even if you try to stick to the recommended doses of caffeine per day, you still need to take them on a fuller stomach.
6. Caffeine can increase the risk of heart disease in young adults who suffer from mild hypertension.
According to a 2015 study on the long-term effects of caffeine, it was proven that drinking coffee can increase the risk of cardiovascular disease, primarily heart attack. However, this was only true for adults of 18–45 years of age who have mild hypertension, as these were the people involved in the study.
7. Caffeine is linked to muscle breakdown.
Caffeine is linked to a wide variety of health issues. Even though most problems are rare and only connected to heavy caffeine consumption, some caffeine side effects need to be taken seriously. That’s especially true for rhabdomyolysis — a rare, yet serious condition that causes muscle breakdown, which leads to a whole host of additional health issues. A person may develop this condition due to excessive coffee consumption.
8. Caffeine affects the brain by creating an alert feeling of energy and wakefulness that people tend to crave.
Caffeine resembles a molecule called adenosine that’s already present in the human brain. Due to this, we could see caffeine as a neurotransmitter that can fit into the receptors for this molecule and block them off. By doing this, the brain creates a sense of alertness and energy for as long as it takes the body to metabolize the caffeine.
This is one of those caffeine facts that not many people know about. It shows that coffee can only keep us awake for as long as we keep drinking it, which can easily lead to excessive consumption and detrimental effects of caffeine on the body.
Furthermore, this kind of brain stimulation is one of the few reasons why some healthcare professionals believe that we can be addicted to caffeine. However, others don’t feel that this can qualify caffeine as an addictive substance.
9. The main signs of caffeine addiction are reflected in a person’s day-to-day functioning.
It’s not easy to characterize this addiction, nor is it easy to determine if someone has it. The only way to conclude that a person might be addicted to caffeine is to see how much coffee affects their behavior. The more caffeine affects a person’s functioning, the more addicted they are to the substance. If you’re afraid of becoming addicted, you should never drink more than the before-mentioned 400 milligrams or four cups of coffee.

Therapeutic Effects of Caffeine
Caffeine isn’t only a powerful stimulant that allows you to feel energized all day long. It provides other valuable benefits.
Let’s check them out.
26. Caffeine taken together with specific pain relievers can be effective against migraines.
27. Caffeine is beneficial in treating Parkinson’s disease.
There are many short-term effects of caffeine, but you are probably unfamiliar with the fact that several studies have connected caffeine and Parkinson’s. In essence, caffeine lowers the risk of developing this terrible disease, and it can reduce the reduced movement symptoms of the disease within three weeks of regular coffee consumption.
It’s still unclear why caffeine can have such a sizable effect on Parkinson’s, but researchers have found that people with the disease tend to have lower caffeine levels in their blood.
What is caffeine?
Everyone knows about coffee and caffeine, but do you really know what it is precisely? In essence, it’s a natural central nervous system stimulant and the most widely consumed psychoactive drug in the world. We can find it in coffee, tea, and cacao plants. Caffeine works by stimulating the central nervous system, and thus the brain. By doing this, it helps you stay alert and, in turn, prevents the beginning of tiredness and sleepiness.
The history of caffeine states that it was first consumed as early as 2700 BC, while the first caffeinated soft drinks were created in the late 19th century. Today, as much as 80% of humanity drinks a caffeinated beverage every day.
Why isn’t caffeine listed on nutrition facts labels?
Many people wonder why caffeine isn’t among the many nutrition facts that food products have listed on them. The truth is that all of these products have naturally occurring caffeine in them, and the FDA doesn’t require manufacturers to list caffeine in the nutrition facts if this is the case. However, if caffeine is added to a product, the manufacturer has to list it among the ingredients only, so you will rarely find caffeine listed in the nutrition facts. This is because caffeine is not considered a nutrient, in whichever form it comes.
How much caffeine is consumed every year?
You probably already know that Americans are obsessed with coffee, which you have already seen from our stats that rank the US at the very top globally when it comes to the total amount of coffee consumed in the country.
However, when it comes to annual numbers, Americans drink around 400 million cups of coffee per day, which turns into 146 billion cups per year! This makes the US the leading consumer of coffee in the world, according to these numbers.
What age group consumes the most caffeine?
As it stands, caffeine is consumed on an almost insane scale. Americans are essentially crazy about coffee and other caffeinated drinks, but that doesn’t mean that people of all ages love coffee to the same extent.
Unfortunately, it’s not easy to find the correct answer to this question, as there’s not enough data that would paint a definitive picture. However, most studies show that the older people get, the more caffeine they consume. Furthermore, it seems that caffeine consumption peaks somewhere between 50 and 70 years of age, after which people tend to start drinking a lot less coffee and other caffeinated drinks.
Is a lot of caffeine bad for you?
We’ve talked a lot about both the negative and positive effects of caffeine. However, we haven’t given you a definitive answer to this prevalent question.
Even after such a long time since we first started consuming caffeine, and despite the fact that coffee is the most popular beverage globally, the research is still conflicting when it comes to the long-term effects of coffee and its safety.
The most commonly accepted conclusion is that it’s best to stick to moderate consumption of caffeinated drinks as that’s the best way to deter all known harmful effects of long-term caffeine consumption. So be moderate with your coffee drinking habits, and everything will be alright!
