Coffee is the second most marketed product on earth, an unmistakable indication of the passion for one’s way to drink it with an intense flavor and a strong discharge of energy. But have you ever wondered what happens to the body when we drink coffee? Here’s what the experts say.

It makes us happier
There is a reason why many people start their day with a coffee: it makes us happier. The psychotherapist Dana Carretta said: “Dopamine, the hormone of well-being, can not be reabsorbed into the bloodstream Any type of drug that produces an effect on the “three hormones of wellness” (dopamine, oxytocin and serotonin) will probably make more “. But before you unleash a liberating dance and drink a liter of coffee, remember that this increase in happiness occurs only when coffee is consumed in moderation. Caffeine stimulates the release of dopamine, so research has linked it to a reduction in the risk of depression. That said, excessive consumption of coffee could lead to an increase in anxiety and agitation, so limit yourself to 1-3 cups a day.

Dr. Svetlana Kogan said: “When we drink coffee, our heartbeat accelerates and increases in blood pressure,” said Dr. Svetlana Kogan The feeling of being in a state of mind begins to diminish.

It makes us see better
If you wake up with the cloudy view, it’s not just your imagination. The vision improvement is one of the positive effects of that state of alertness. Dr. Alex Roher explained: “Within 20 minutes of drinking coffee, caffeine releases adrenaline.” Dietitian and nutritionist Melissa Hooper agrees and adds: “Caffeine activates the sympathetic nervous system to increase the natural production of adrenaline, which could cause increase in mental attention and lead to a better view while the pupils dilate slightly “.

Urinary urge incontinence Hooper explained: “Caffeine is a diuretic, which increases urinary production and therefore diuresis in some extreme cases can therefore cause diarrhea and problems for people with irritable bowel syndrome. “

Can caffeine kill? A 37-year-old woman attempts suicide by ingesting 27 grams of caffeine: the immediate toxic effect of cardiac arrest with hypotension, because caffeine causes a real poisoning. 350 capsules of coffee have been developed in a catastrophic reaction on the part of the body.
The average lethal dose of caffeine (LD50) is 150-200 mg per kilo of body mass, but it is impossible to reach this threshold with simple nutrition.

Caffeine and insomnia
Among the most known side effects of caffeine, in the first place there is insomnia: caffeine, in fact, is a methylxanthine that causes effects at the level of the central nervous system, then stimulates concentration, decreases the sense of fatigue and increases caution ,
Even the caffeine contained in a cup of coffee is said to have various side effects and to prevent the person falling asleep; it is not advisable to drink coffee before going to sleep, especially for the most sensitive to its action.

 
Cardiovascular effects
At much higher doses, caffeine can cause seizures, which can be fatal. Regarding the side effects of caffeine in the cardiovascular system, this substance may have chronotropic and positive inotropic effect (increase in strength and heart rate): as a result there may be situations such as increased cardiac output, tachycardia and increased pressure (albeit mild at normal doses of consumption).
It has been seen in some subjects the habit of consuming coffee has led to an adverse effect, to light arrhythmias.

Side effects of caffeine

Other side effects
Also, the kidneys are affected by the side effects of caffeine: there is an increase in glomerular filtration and, at the same time, a decrease in the tubular reabsorption of sodium, which stimulates diuresis.

Methylxanthines in general, including caffeine, could cause bronchodilation, a side effect that affects the smooth muscles of the respiratory system.

It is a moment of pause from work, a moment to free the mind and return to discover its own energy. But in that substance, enclosed in the cup we drink every day, what is hidden? The site “Eat this, not that!” has compiled a list of 35 things that perhaps, we do not know about caffeine. It could stop hair loss, for example, or absorbed through the skin. “Not everyone is aware of his power – we read in the article – that’s why we want to reveal some secrets”.

1. Caffeine imitates an important molecule in the brain

The chemical structure of caffeine is similar to that of adenosine, an important molecule that acts as a neurotransmitter. L ‘adenosine serves to signal the brain levels of oxidative stress (fatigue, stress). Caffeine has an antagonist, effectively interfering with the work of adenosine and thus having a stimulating action on the central nervous system.

1. It is not recommended to drink coffee as soon as you wake up

morning

We get out of bed and wake up, we prepare a nice cup of coffee: wrong. Contrary to what we usually believe, we do not need it at the moment. This is because the level of cortisol and caffeine cassisol in the upper part of the cortisol and cassisol in 20-30 minutes after awakening and mix cortisol and caffeine would increase. Everything changes mid-morning and mid-afternoon, when cortisol levels are lower, and we can, therefore, allow ourselves a cup without problems.

1. Caffeine takes 10 minutes to take effect

To feel more awake, after having a coffee, we have to wait at least ten minutes: this is the time frame that caffeine takes to make an impact. But the peak efficiency is 45 minutes from the first sip. The effect lasts for three to five hours, although much depends on the metabolism of those who take it.

1. Finland is the country where most coffee is consumed

Italians are not the biggest consumers of coffee: in our country there are about 5.9 kg of coffee per capita, while in Finland about 12 per capita are consumed. The country where you drink less coffee, however, is Puerto Rico, with 400 grams of coffee for each person. The world consumption average is 1.3 kg per person per year.

1. The effect varies from person to person

coffee

Not everyone has the same effect by drinking a cup of coffee: age, gender and ethnicity can enter the body in our body. For example, women usually metabolize caffeine faster than men, as do smokers compared to non-smokers. The peoples of Asian origin, however, would tend to be more slow than the others.

It seems like a doctor’s recommendation of the mutual, but eating a healthy way of life in many ways. We are not talking about a weight loss diet, but a general attention to eating habits, and not only that affect the mood, digestion and general conditions of the body. Healthy and natural foods are the most digestible, which accelerate the metabolism and condition the sense of lightness and well-being. Not to mention that in the discussion of bad habits. To improve the quality of life, here are 10 habits to be taken away.

1. Eat more healthy foods, like fibers
   The fibers help regulate the intestine, which is our second brain. A good functioning of the intestine helps the immune defenses, and helps to stay healthy. It is no coincidence that those are stressed or anxious. They are both in vegetables and in pasta, but in the first and second courses it is better to choose fresh and seasonal vegetables because they are richer in mineral salts and vitamins.
2. Reduce sugars
   Serotonin levels and better mood (just think of chocolate), yet too many sugars are addictive and often negative to emotional states such as sadness or stress. An excess of sugar is an enemy of any diet, understood not as a weight loss regime but as a set of good eating habits.
3. Increases the intake of vitamin D
   Vitamin D is responsible for the reaction of serotonin, the hormone of happiness we talked about earlier. It is also synthesized through sun exposure, but it is important to increase its presence in the body through specific foods, such as eggs, fresh cheeses or fish, such as salmon.
4. Reduce the number of coffees
   It is true that caffeine makes you feel more alert and awake, but it is taken in excess irritates and agitates. It can cause sleep disorders, which do not help good mood.
5. Make a more balanced diet
   That is to say, more varied. Eat pasta, bread, meat, fish, cheese, fruit and vegetables. If you need to lose weight, do not rely on those drastic weekly diets that give you immediate results in the short term. You prefer the classic Mediterranean diet, but limit the oil you use for two tablespoons a day.
