Tell you the secret of four coffees to make you drink healthier.

If you don't drink a few mouthfuls of coffee every day, you feel exhausted? But are you worried that drinking too much coffee is harmful to your health? It's just that when you want to complain about the disadvantages of drinking coffee, Vanderbilt University in the United States has set up a coffee research center to actively conduct a comprehensive discussion on this natural substance, which has been deeply misunderstood for a long time, and apply it to medical resources to help fight cancer, AIDS and civilized diseases. As for the benefits that you don't know, I will tell you clearly now.

Improve mental thinking:

According to a recent study from the University of California School of Medicine, drinking caffeinated drinks before you give a speech or interview can help make a woman's mental thinking more flexible.

Hyla Cass, a professor at the university, said that because caffeine enhances the release of dopamine (Dopamine) by the brain, it not only helps focus, improves thinking logic and memory, but also leads to positive motivation and activity. however, he also stressed that this effect does not last long, at most an hour, so you might as well have a cup of coffee half an hour before an important meeting or interview.

Relieve headaches:

Do you have a headache without a cup of coffee every day? A report from the Diamond Headache Clinic in Chicago confirmed that caffeine does have a headache-relieving effect.

Dr Seymour Diamond says caffeine's pain-relieving effect is mainly related to its ability to limit blood flow, especially if your headache is caused by dilated blood vessels in the brain.

However, it is worth noting that this caffeine therapy is not suitable for patients with long-term headaches, because excessive consumption of caffeine, more than 150mg of ╱ for days, will relatively aggravate the headache.

Help to breathe:

It sounds strange, but Marianne Frieri, a professor of medicine at Nassau University Medical Center in New York, points out that there are many patients who have been suffering from asthma problems for a long time.

If you have a cup of coffee or strong tea in the morning, you will have a smoother feeling of the respiratory tract, while studies by American medical units have found that caffeine has an anti-allergic substance, which can inhibit histamine in the body and dilate blood vessels, so it can have the effect of relieving and relaxing the respiratory tract, making people feel that breathing becomes smooth, but they do not recommend patients with asthma. Improve the problem of dyspnea by relying on drinking caffeinated drinks.

Caffeine stimulates appetite

Although caffeine does have the effect of accelerating fat decomposition in the body, and caffeine-based weight loss is also popular, have you ever known that you usually have eating ailments or inexplicable hunger? it's probably because of the caffeine in the body!

As caffeine affects the central nervous system of the body, it increases the secretion of gastric acid and stimulates appetite, making people prone to hunger or wanting to eat, and if taking high doses of caffeine, it can also lead to side effects such as anxiety, nausea and insomnia. Therefore, for those who love beauty to lose weight, it is best to think twice before they want to use a caffeinated drink to refresh themselves.
