It's easy to get sleepy, so you can drink some coffee properly, but don't drink more than one cup of coffee a day. Although coffee can relieve fatigue, long-term drinking of large amounts is also bad for the body, and only proper drinking can help relieve fatigue.

There are many reasons for feeling sleepy after drinking coffee, such as physical factors, the formation of antibodies after drinking too much coffee, the lack of B vitamins in the body, extreme drowsiness, etc.

1. What are the reasons for being sleepy when drinking coffee?

1. Physical factors. Feeling sleepy after drinking coffee may be due to the fact that there are a lot of strong caffeine antibodies in the body, which resist the refreshing effect of coffee.

2. Drinking coffee for a long time is easy to form antibodies, just as taking cold medicine for a long time will weaken the efficacy, the refreshing effect of caffeine is greatly weakened.

3. Lack of B vitamins in the body. Drinking a lot of coffee can cause the body's metabolism to be too fast, increasing the consumption of B vitamins related to the body's neuromuscular coordination. So, people who are deficient in B vitamins may feel more sleepy after drinking coffee.

4. Generally speaking, coffee can refresh the mind and relieve fatigue, but if the body is too tired and sleepy, drinking sweetened coffee and coffee companions can have a hypnotic effect.

It means that you are already very sleepy, and the coffee can't control you.
