Introduction: When you need to stay up late, many people's first thought is to drink a cup of coffee to stay awake, but is this really effective?
The caffeine in coffee does have a refreshing effect, but this effect varies from person to person and is only temporary. Drinking large amounts of coffee can speed up the body's metabolism, increasing the consumption of B vitamins, which are related to nerve and muscle coordination. People who lack B vitamins are more prone to fatigue. Over the long term, this can create a vicious cycle where the need for coffee increases, but the refreshing effect diminishes.
In addition, caffeine has a diuretic effect. After drinking coffee, you will need to urinate frequently, which not only interrupts your work but also leads to dehydration in the body. Dehydration can also cause fatigue and drowsiness.
If you know you have to stay up late, you can have a bowl of multigrain porridge for dinner instead of some staple food. While providing B vitamins, it can also supply abundant carbohydrates and a strong sense of fullness.
