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. Consuming 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: the body's demand for coffee increases, yet its refreshing effect diminishes. Furthermore, caffeine has a diuretic effect, so drinking coffee can lead to frequent urination. This not only interrupts your work but also causes the body to become dehydrated, and dehydration can also lead to fatigue and drowsiness.
If you know you'll be staying up late, you can have a bowl of multigrain porridge for dinner instead of part of your staple food. While providing B vitamins, it also offers a rich source of carbohydrates and a strong sense of fullness.
