You can often hear that coffee negatively affects the state of physical fitness: let’s try to figure out if this is true
Coffee euphoriaOver the years, coffee has been one of the favorite drinks in most countries. Many people drink coffee because they like the taste of it. But in fact, in the process, adenosine is produced – a substance whose concentration gradually decreases during sleep until awakening occurs. Coffee has about the same effect. Also, the blood vessels narrow and the sugar content in the blood rises, due to which the body becomes energetic and vigorous.
Keep in mind that caffeine is addictive. An experiment was conducted in which those who were “addicted” to coffee were forced to give it up for several days and then undergo tests. Then they drank coffee and took the tests again, and the first results were worse than the second. In addition, when drinking more than three cups of coffee a day, the body experiences sensations comparable to stress – increased blood sugar and blood pressure, more likely to have a stroke and heart disease.
Can drinking coffee cause dehydration?
It depends on the amount of the drink. If you drink it in moderation, then dehydration is very minor. But if you consume more than 5 cups, you will have to take measures to protect yourself from a lack of water in the body.
How does coffee drinking affect blood pressure levels?
In moderation, practically nothing. But scientists have found that coffee is contraindicated for those who already have problems with blood pressure.
In an experiment on people over 60 years old who drank about 4 cups of coffee a day, it was found that the risk of dying from heart disease was lower compared to those who drank less coffee. The fact is that with age, the pressure decreases, which leads to a heart attack. Coffee increases blood pressure, thereby offsetting this effect.
The oils in coffee help regulate not only blood pressure but also cholesterol levels.
Coffee and heart disease
One of the factors contributing to the onset of heart disease is inflammation. Due to the antioxidants it contains, coffee has an anti-inflammatory effect on the body. This effect has been tested experimentally in older women.
The connection between coffee and diabetes
The antioxidants in the drink help keep insulin production normal. This is why coffee in large quantities significantly reduces the risk of diabetes. However, caffeine-free coffee has a similar and even more powerful effect.
Effects on the liver
Surprisingly, in the course of experiments it was found that for alcohol lovers, coffee is a kind of cure for liver cirrhosis. The effect develops with a daily consumption of 3-4 cups of the drink.
What effect does coffee have on the brain?
Due to its high content of antioxidants, when consumed in moderation, coffee slows down the rate of brain aging and reduces the risk of developing Alzheimer’s and Parkinson’s diseases .
