What are the pros and cons of drinking coffee for teenagers

Many people feel sleepy while working and many people choose to use refreshing drinks to help themselves continue working. In fact, refreshing drinks such as coffee contain a lot of caffeine, which stimulates the nerves in our brain. We should learn to recognize the adverse effects caused by caffeine. Apart from the brief brain excitement, the rest will affect our daily diet and the stability of the body's internal environment.

The main stimulant contained in coffee is caffeine. In addition, it also contains fat and minerals such as magnesium, potassium, copper, as well as vitamin B, aroma substances and toxins. That is to say, coffee has no nutritional value, but due to the effects of caffeine, coffee has many positive and negative effects on the body.

On the nervous system: Caffeine can excite the brain, eliminate the feeling of laziness, make people feel relaxed and happy, and help people concentrate, think quickly and evoke memory. Studies have shown that caffeine can increase people's calculation and computer typing speed and make car drivers more agile. But there is no scientific evidence to prove that caffeine has an effect on improving work quality.

Cardiovascular effects: Drinking coffee can increase heart rate, blood pressure, promote blood circulation, and enhance myocardial contraction.

On the urinary system: Caffeine can dilate renal blood vessels and increase glomerular blood flow, thereby increasing the kidney's water permeability and detoxification function. It can be said that coffee has a diuretic effect.

For the respiratory system: Caffeine can relax the smooth muscles around the trachea, thereby dilating the trachea and increasing breathing volume. However, caffeine cannot be used as a drug in the clinical treatment of asthma.
