1, no breakfast
After a night's sleep, the food in the body has been consumed and the blood sugar is low. Breakfast can keep blood sugar stable. However, if the breakfast is not good, the blood sugar in the morning will be low as a whole, and the mental state will be bad. You will definitely eat a lot at noon, which will lead to excessive gastrointestinal burden and easily lead to gastritis and indigestion. For teenagers, due to the lack of nutrition and energy, the brain can easily fail to develop and operate normally, which will hinder the development of memory and intelligence over time.
2. Too little sleep
Sleep is a very important way for people to recover their physical strength. Everyone should have it, or they will be listless. It is most suitable for normal people to sleep for about eight hours. However, nowadays people often stay up late for work or entertainment at night, and have study and work tasks the next day, so the sleep time will naturally decrease, but the reduction of sleep time will make their state decline and their grades are not good. Moreover, long-term lack of sleep will lead to decreased immunity and easy to get various diseases.
3, excessive exercise
Proper exercise can improve the body's ability to cope with changes in the external environment, but excessive exercise can damage the health of the body. In daily life, we can achieve the effect of exercise by choosing aerobic exercise. You can choose running, swimming, table tennis, etc., and you can also do some team sports and simple dances to keep slim, strong and energetic.
In addition to the above three habits, there are many other habits that have the same effect, but due to space constraints, I won't explain them here. Want to know more about health knowledge, please ask questions.
