Eating too much rice and flour makes you sleepy in the afternoon.

At present, carbohydrates account for about 2/3 of the total calorie intake of Chinese food, mainly refined white flour, white steamed bread and white rice. These foods look pure and white, but they lack nutrition. The glycemic index is above 80, which is as high as sugar. In other words,100g of refined rice flour is equivalent to 80g of glucose or100g of sugar.

For the arrangement of three meals, China people pay attention to "good breakfast, full lunch and little dinner". "Eating more, high carbohydrate ratio and high glycemic index are the three characteristics of China lunch." Dr. Ximu believes that this lunch structure makes the total blood sugar load increase and decrease sharply, and the change is like a roller coaster: within 30-45 minutes, the blood sugar in the body rises rapidly, stimulating a large amount of insulin secretion, and then the blood sugar drops rapidly, reaching a trough in about 2-3 hours. What makes people weak and sleepy is the sharp drop in blood sugar.

Sleepiness in the afternoon is caused by biological rhythm. After a hard morning's work, the body naturally needs to rest and replenish its strength after lunch, so people's spirit in the afternoon is not as energetic as that in the morning, especially around 4 pm, when they are in the most trance, which is inefficient and prone to mistakes.

You ask everyone how to solve the problem of being sleepy in class, which shows that you are a person who loves learning. Here are two ways for you to learn:

First, try to keep enough sleep time every day, eat more foods rich in vitamins for breakfast and lunch, and don't be too full for lunch. Eat 80% and bring some snacks after three o'clock.

Second, put a bottle of essential balm in your pocket. When you are sleepy in class, put it between the temple nostril and the upper lip, so that you can wake up and have no side effects. This is a way for my children to solve their drowsiness when reviewing for the college entrance examination, especially in summer. I hope I can help you.
