Staying up late for coffee will make you more sleepy.

When you need to stay up late, the first thing that comes to mind is to refresh yourself with a cup of coffee, but does it really work? The caffeine in coffee does have a refreshing effect, but it varies from person to person and is only temporary. Drinking a large amount of coffee will speed up the metabolism in the body and increase the consumption of B vitamins related to nerve and muscle coordination, while people who lack B vitamins are more likely to get tired and may form a vicious circle in the long run. The demand for coffee is increasing, but the refreshing effect is getting worse and worse. 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, which will also lead to fatigue and drowsiness. If you know you want to stay up late, you can drink a bowl of porridge instead of part of the staple food at dinner. It not only provides B vitamins, but also provides rich carbohydrates and a strong sense of satiety.
