Is caffeine bad for your adrenal glands?

Fact check - 5 common myths about coffee

Coffee is an integral part of the everyday life of many gourmets. And as with everything that is part of our daily life, there are also some myths about the drink made from the roasted bean. Sometimes with a greater and sometimes with a smaller truth content. We reveal.

One thing quickly becomes clear when you take a look at the most common myths about coffee enjoyment: They are usually only half true. The answer to most consumer questions is ambiguous. A differentiated consideration of the topic can help. Friends of clear answers will rarely find anything in this regard. We scrutinized five persistent half-truths.

Myth 1 - Coffee helps with stress

It's commonplace in offices. If there is too much stress, the next coffee machine is visited first. A quick cup of coffee promises a remedy, it is said. But is there really anything to this theory?

Science says “puff cake”. The reason for this lies in the caffeine. And depending on the type and type of preparation, this is abundantly contained in the coveted bean juice. Caffeine stimulates the adrenal gland to produce the stress hormone adrenaline, thus increasing motivation. We become more resilient and are able to achieve great performances for a short time - both physically and mentally.

But adrenaline rightly scolds itself as the stress hormone. Coffee does not help against stress, it creates stress. Only in this way can the crucial energy reserves be released in extreme situations.

Anyone who nevertheless observes in the self-study that the stress level drops significantly with a cozy cup of coffee should not look for the reason for this in the coffee, but in the word cozy. The decrease in tension is more likely to be attributed to the enjoyable break than to the declared awakening from the cup.

Myth 2 - Coffee makes you awake and efficient

This is followed by the next coffee myth. Coffee is supposed to make you awake and productive. Anyone who has carefully read what has been described above will be able to answer this question simply and directly: Of course, coffee wakes you up and increases motivation!

But it is not that simple. It is true that the caffeine it contains stimulates adrenaline production, but the short-term effect of the worker drug is decisive. In fact, coffee has a stimulating effect at first and suppresses the feeling of tiredness. However, the whole thing is reversed very quickly.

This effect is particularly impressive when it comes to desk work. Anyone who drinks a cup of coffee against fatigue during the course of the working day will notice that the highly praised effect shows its downside after an hour in the office chair. Signs of exhaustion, tiredness, headache and irritability spread. What helps? - The next cup of coffee, of course.

Myth 3 - Coffee removes fluids from the body

If you don't want to miss out on the increased motivation through coffee, you have to consume a few cups in the course of a working day. But there seems to be a catch: The myth that coffee has a dehydrating effect persists. Once again, it's not that simple.

Caffeine has a short-term diuretic effect, so it leads to fluid loss. If you regularly consume coffee in equal amounts, your body goes through a process of getting used to it. The diuretic effect diminishes, the myth vanishes into thin air. Strictly speaking, the reverse is true. Coffee can even be included in your personal fluid balance.

Myth 4 - Too much coffee is harmful to your health

Then nothing should stand in the way of constant coffee enjoyment in the service of willingness to perform, right? Unfortunately, fluid balance is not the only point that deserves attention.

According to various studies, up to three large cups of coffee a day are harmless to your own health. Quantities that go well beyond this should be viewed more critically. The danger is the overdose of caffeine. Unpleasant symptoms such as nervousness, muscle tremors, gastrointestinal problems, dizziness and headaches appear.

While amounts of up to 350 milligrams of caffeine per day (equivalent to around three large cups) can even have a health-promoting effect in different areas, the effect turns into the opposite with larger amounts.

Since different types of coffee, preparation methods and roasting variants ban different caffeine concentrations in the cup, the three-cup rule should be viewed as a rule of thumb. In any case, it is not the ultimate wisdom.

Myth 5 - Coffee is addictive

Yes and no! Most of the myths surrounding coffee enjoyment have two sides. A certain truthfulness cannot be dismissed out of hand. The myth of coffee makes you addict is similarly differentiated.

It is undisputed that the body has to get used to the constant consumption of caffeine. This is not only reflected in the diuretic effect, but also in the stimulation of adrenaline production in the adrenal gland. If you want to have the same effect over the long term, you theoretically have to drink more and more coffee.

Caffeine-free days, for example on weekends, can help. If you can do without the promising bean juice here, you can look forward to the familiar effect again on Monday in the office.

Coffee does not make you physically dependent, which has long been a very controversial issue in science. The reasons for feelings of dependency are more to be found in the human psyche. Rather, the power of habit is the master of desire. A cup of coffee is simply part of certain situations.

Withdrawal symptoms typical of addiction are not observed in connection with caffeine. The question then rightly arises: Isn't decaffeinated coffee sometimes enough?
