For most people, especially Brazilians, coffee is part of their daily routine: one when they wake up, another after lunch, and another at the end of the afternoon to refuel for work. For many people, it is virtually impossible to get through the day without the help of caffeine. But in the end, What effect does drinking drink have on the body?
The Coffee starts to take effect 10 minutes after the first sip. Duane Mellor from the British Dietetic Association says this reflects how quickly caffeine is absorbed into the bloodstream by different parts of the digestive system.
In a report in British newspaper the Daily Mail, he explained that while some may be absorbed through the mouth or stomach, most occurs in the intestines. And it is precisely after the caffeine is absorbed that a person feels the required increase in energy from a drink.
However, experts explain that this “urge” is actually a bit of a deception. Because caffeine doesn’t actually provide energy. Instead, it works by temporarily blocking your body from interacting with adenosine, a chemical that causes fatigue.
For caffeine, Chemical structure similar to adenosineso it fits like a key in a lock and blocks receptors in the body. This prevents the molecules from producing a fatigue effect, leaving coffee drinkers in a more alert state.

Mellor explains that caffeine causes the following symptoms 20 to 30 minutes after ingestion: increase in blood pressurewhich lasts up to about 4 hours after ingestion.
He says the reasons are: substance constricts blood vessels. As a result, your body increases your heart rate. The effects are often temporary, which is why health authorities don’t recommend drinking more than four cups of coffee a day.
According to Mellor, Caffeine’s effects peak at 45 minutes. At this time, you will reap the greatest benefits in that you will feel more energy and improved focus.
After drinking coffee for an hour, Another undesirable effect occurs: diuresis.. According to the UK’s National Health Service, this happens because caffeine inhibits the production of antidiuretic hormone (ADH), meaning your kidneys reabsorb less water and cause a stronger urge to urinate.
But caffeine consumption doesn’t just cause you to pee more. This substance can also be activated even more significantly contraction of the colonforcing the contents into the large intestine. Therefore, many people feel the urge to defecate when they drink coffee.
How long does it take for caffeine to be metabolized? It depends on the person. But Mellor says that for most people, the stimulant effects of caffeine begin to wear off after one to two hours.
Even if it is not excreted from the body, May remain in the body for up to 12 hoursa person begins to feel tired and lack of concentration. This is because adenosine, which was not previously bound to receptors, begins to bind again, causing fatigue.
