Are there any side effects of drinking coffee? Are there any side effects from drinking coffee?

Coffee is one of the world's three major beverages, and it is a beverage made from roasted coffee beans, and it is the main drink popular in the world along with cocoa and tea. -Coffee is rich in free fatty acids, caffeine, tannic acid and other nutrients -It can reduce muscle fatigue and eliminate fatigue -Coffee also has the function of relieving hangover.

Let's talk about the efficacy first, I have experienced that the refreshing and anti-fatigue effect of coffee can be said to be immediate.

Recently, the neighbor's child has been crying (for unknown reasons, it may be sick), the sound insulation of the rental house is not good, and I am a very light sleeper, as soon as the child cries, he will basically wake up, and he can't sleep well all night.

It is especially easy to get sleepy at work during the day, especially at 11 a.m. and 3:30 p.m., yawning constantly, worshipping God from time to time, and forcibly waking up with a hammer on the thigh from time to time.

Until yesterday afternoon, I couldn't hold it anymore, so I went to brew a cup of coffee (the company's coffee machine, a German brand called derrla, not expensive), after drinking, the sleepiness disappeared, which is much more obvious than the refreshing effect of energy drinks.

As for ***, I feel that my teeth will be a little yellowish if I drink too much coffee, which is similar to smoking and drinking tea, and I haven't studied it.

As for what everyone says about drinking coffee is addictive, I don't feel like it, I used to drink coffee a lot, and then I looked in the mirror and felt that my teeth were a little yellow, and I didn't drink much if I suspected that it was the reason for drinking coffee, and I didn't drink it anymore, and I wouldn't have any feelings like I couldn't quit or become addicted (although after I didn't drink it, I didn't feel my teeth whiter).

There's nothing ***, there's nothing ***, drink it, it's good.

Coffee can cause increased stomach acidity, so for people who have stomach problems, drinking coffee can make stomach problems worse, especially for stomach ulcers and gastroesophagus.

Coffee has the effect of improving the body's alertness, sensitivity, memory, and concentration, but when the usual dose is exceeded, excitement will appear, which will affect the nerves and the body.

Excessive coffee consumption can cause nervousness, and for patients with anxiety disorders, sweaty palms, palpitations, tinnitus, etc. It can lead to an increase in blood pressure and a tendency to cause bone loss. Excess caffeine can cause people who are intolerant to caffeine to increase their heartbeats by 10 to 20 beats per minute and may cause brief irregular heartbeats.

It can easily affect the digestive system and kidneys.

Coffee should be drunk in moderation, preferably after breakfast and lunch, because it can promote gastrointestinal peristalsis and help digestion, and people with high blood pressure should drink as little as possible.
