What happens to the body when you drink coffee?

Drinking a sufficient amount of coffee not only helps refreshing spirits, but also benefits the eyes, the cardiovascular system, the teeth, the stomach and some other organs.

After drinking coffee, what happens to the body?

Brain

According to Yahoo, Marc Leavey, a health care specialist at Mercy Center in Baltimore, caffeine in coffee has the ability to strengthen the nervous system and concentration. Normally, the brain works by releasing a chemical that passes through synapses. When you drink coffee, caffeine stimulates this transmitter to work more efficiently.

So you will feel more alert after about 30 minutes and last for a few hours.

Conversely, drinking too much coffee will overwhelm the brain system, undermining concentration. Therefore, instead of being alert, you will feel restless and worried.

Eye

According to Dr. Nieca Goldberg, a cardiologist at Langone Medical Center (USA), coffee stimulates the brain system to release adrenaline production, causing the pupil to relax slightly, making vision sharper.

Drinking a moderate amount of coffee is beneficial for organs such as brain, eyesight, heart .

Oral teeth

Coffee contains many polyphenols , a micronutrient that has been shown to be effective in destroying dental plaque and harmful bacteria.

However, when polyphenols remove plaque, sugar and milk will easily penetrate the area inside the teeth, can demineralize and cause tooth decay. They also make teeth change color quickly.

Therefore, you should use a straw to drink coffee to limit the amount of sugar entering your teeth, or brush your teeth right after drinking.

Heart

Caffeine increases the sensitivity of the nervous system, activates the cardiovascular system. Therefore, about 15 minutes after drinking a cup of coffee, blood pressure will increase by 10-15%.

Expert Marc recommends that you only drink about 2 cups of coffee (about 170mg each). Drinking more than the recommended amount is not good for people with heart disease, high blood pressure, tachycardia and some potential heart problems.

Stomach system

Caffeine stimulates gastric receptors, promotes about 10-15% fluid secretion, helping you digest food faster.

The reverse side of this movement is that it can cause reflux, heartburn . The reason is that caffeine relaxes the sphincter, a bundle of muscles located on the bottom of the esophagus, making food from the stomach go back into Stomach.

Bowel and bladder

Expert Marc said caffeine stimulates the intestines, making this system work faster and more efficiently. However, the intestinal waste needs a certain amount of time to become a solid. If the intestines work too fast, the waste is still liquid, causing irritable bowel syndrome (IBS), especially dangerous to health.

Coffee acts as a diuretic, affecting the tubes in the kidneys, thus increasing the amount of urine, making you go to the toilet more.
