Coffee is recognized as a healthy drink, but drinking coffee must be done reasonably and scientifically to be beneficial to health, and it must be done in the right amount at the right time. Drink a cup of coffee after getting up in the morning to wake up. A light sip can refresh you while working during the day. The coffee can be slightly stronger at this time. It is better to drink a little light coffee after a meal or in the evening. Both coffee and tea have a refreshing effect, but they are not suitable for drinking with meals and should be consumed after meals. Some friends love drinking coffee very much, but they are afraid that they will get angry if they drink it too often. We often see many people just ordering coffee. This way of drinking coffee is not healthy. You should drink coffee with a cup of water. This has two benefits: First, drink a sip of water before drinking coffee to wash away the odor in your mouth. Second, due to the diuretic function of coffee, drink more water to increase urination and promote kidney function. In this way, you can enjoy the delicious taste of coffee without having to worry about getting angry. It really kills two birds with one stone.

Caffeine: The caffeine in coffee is difficult to dissolve in cold water, but is easily soluble in hot water. Caffeine stimulates the cerebral cortex, eliminates drowsiness, increases feeling and thinking ability, and acts as a cardiotonic to adjust heart function. It also has the effects of dilating kidney blood vessels, diuresis, etc. However, caffeine is not just coffee. A typical cup of coffee contains 60-65mg of caffeine. However, excessive caffeine intake may lead to tinnitus and myocardial hyperactivity (rapid heartbeat and increased pulse rate). and uneven pulse beat, so you must drink coffee in moderation.
