Staying up late for coffee may be more sleepy. Coffee needs attention.

When staying up late, many people are used to drinking a cup of coffee to refresh themselves, but does this really work? Studies have shown that drinking a lot of coffee will accelerate the consumption of B vitamins, and people who lack B vitamins are more likely to get tired. In addition, caffeine has a diuretic effect. After drinking coffee, you will frequently go to the toilet, which will not only interrupt your work, but also cause a lack of water in the human body, which will also lead to fatigue and drowsiness.
