Experts suggest drinking more coffee and drinking less according to your own physique.

Finally survived the hot summer, but the spirit will still feel tired, the original "autumn lack" followed.

At this time, many friends like to have a cold cup of cola or tea, and soon feel a lot more comfortable.

Why do these drinks make people feel refreshed? It turns out that these drinks often contain a small amount of caffeine, which helps people reduce fatigue caused by increased energy consumption in hot weather.

When it comes to caffeine, its impact on the human body has been controversial in recent years. In fact, people have many misunderstandings about it, mainly in two aspects:

One is just knowing that caffeine has a refreshing effect, and drinking too much will affect people's sleep.

Caffeine is a natural substance found in the seeds, leaves or fruits of many plants, known as coffee beans, cocoa beans and tea leaves.

Second, many people believe that caffeine can cause osteoporosis.

In fact, calcium deficiency is the main cause of osteoporosis, and other factors include hormones, exercise, nutrients, mineral and calcium intake and people's dietary habits, there is no direct evidence that caffeine causes osteoporosis.

Also, unlike other physically stimulating substances such as alcohol, caffeine has a relatively short-lived effect. For most people, caffeine does not affect their concentration and intelligence, so caffeinated drinks are ideal for drinking in the workplace.

However, caffeine intake is also learned.

It is generally believed that the safe daily intake of caffeine for adults is 300 mg, which is measured in 240 ml. The amount of caffeine contained in each cup of coffee is 65 to 120 mg, the caffeine content of each cup of tea is 20 to 90 mg, and the caffeine content of each cup of cola is 23 to 31 mg.

Therefore, for the average person in good health, drinking 2 to 3 cups of coffee or 5 to 6 cans of caffeinated cola every day will not cause health problems caused by coffee.

Of course, anything that goes too far loses its original effect. Therefore, experts suggest that it is best to decide whether to drink more or less according to the effects of caffeine on their sleep, blood pressure and digestive system, while lactating women and pregnant women should consume less caffeine.
