It's hot, and people are always groggy all day. How to cheer up? Thank you, everyone.

It's too hot, so my brain is always sleepy. How to solve the problem of sleepiness in summer, such as taking a bath, mung bean soup, watermelon and turning on the air conditioner? 1, making full use of functional drinks, a little sleepy. Most people will choose coffee or tea to refresh themselves at this time, but this is only a moment, because this method of refreshing with caffeine can not fundamentally solve the problem of sleepiness. At this time, what the human body lacks is bezoar amine, so it is better to drink some functional drinks containing bezoar amine, such as red bull and pulse. Caffeine prevents us from falling asleep by forcing nerves to get excited, so we can't sleep after drinking coffee. If you drink red bull, you can lie down for a while, and the effect is better. If it's your first time, don't drink too much. One or two glasses is usually enough. 2, listen to music to relax, while watching something to understand, while listening to some relaxed concerts without lyrics to help us remember. (there must be no lyrics, so it's easy to get distracted. 3. Exercise, go out for a walk or jog for half an hour every day, and activate our brain cells through certain aerobic exercise, thus improving our memory and relaxing the tension before the exam. 4. Drink milk before going to bed. Milk can help us sleep. Only with good sleep can we work hard for a warm day. 5. Nuts, as Wu Shuang said, eating some walnuts will help us improve our memory, but I don't like the taste of walnuts very much. In fact, eating any nut has this effect.
