What are the effects of coffee on the body?
coffee is at the heart of many studies. Is it poison or a magic potion? Response elements.
The studies on coffee are as numerous as the number of addicts to this drink. The results are diverse, but a study decided to sort through everything that had been said before. The result is quite surprising and rather reassuring if you are one of the millions of people who drink it every day. Coffee has more benefits than constraints on your body, under certain conditions …
3 to 4 cups a day, no more
The optimal dose of coffee is between three and four cups a day. This is the quantity for which the benefits are greatest. Beyond that, some risks exist.
The study is based on “healthy” coffee, that is to say pure. Sugar, milk, cream or accompaniments totally bias these results. Black coffee is also a drink that contains zero calories. It is also an excellent antioxidant.
Heart and stomach benefit
Coffee increases blood pressure. At rest and provided you have not abused it, the heart rate decreases slightly. In any case, this represents a danger unless you have greatly exaggerated coffee.
The acidity of caffeine allows better digestion after the meal. This factor explains why we are used to drinking after the meal. One of the side effects of this acidity is the risk of heartburn by drinking on an empty stomach in the morning.
A barrier against diseases
Coffee reduces the risk of a large number of diseases: cancer of the prostate, throat, skin, liver as well as leukemia, Parkinson and types 2 diabetes. Keep in mind that these results come from healthy subjects. In smokers, for example, the effects are less.

An enemy for sleep
If coffee has energy, it also prevents sleep. Drinking this drink too late in the day does not allow for a restful sleep.
Caffeine delays and decreases the release of melatonin, the sleep hormone. She is in charge of the regulation of chronobiological rhythms and is synthesized during the night. Coffee disrupts this natural rhythm.
