A discussion on the effects of coffee drinking on the health and IQ of junior high school students

Abstract: Recently, there has been a discussion on the effects of coffee drinking on the health and IQ of junior high school students. Studies have shown that drinking coffee in moderation can improve concentration and alertness, which is helpful for students who study for a long time. However, excessive drinking may lead to adverse effects such as insomnia and palpitations. For junior high school students who are in the growth and development stage, excessive caffeine intake may affect physical health and intellectual development. Drink in moderation and maintain a healthy lifestyle.

As the pace of modern life accelerates, coffee, as a refreshing drink, has gradually become a daily choice for students, especially for junior high school students. Facing the pressure of the high school entrance examination, many parents and students believe that coffee can refresh the mind and improve learning efficiency. But is coffee really suitable for junior high school students? Does it have any effect on the body and IQ?

1. Effects of coffee on the body

Let's understand the impact of coffee on the body. Coffee contains caffeine and other bioactive substances, which can stimulate the central nervous system to a certain extent, improve people's attention and short-term memory. However, for junior high school students who are growing and developing, long-term and excessive drinking of coffee may have some negative effects.

1. Impact on sleep : The stimulating effect of caffeine may interfere with students' normal sleep, resulting in decreased sleep quality, which in turn affects their mental state the next day.

2. Digestive system problems : Excessive coffee consumption may cause stomach discomfort and even cause diseases such as gastritis and gastric ulcer.

3. Bone development : Caffeine may affect the absorption of calcium, thereby affecting the normal development of bones.

2. The impact of coffee on IQ

As to whether coffee affects IQ, there is no clear scientific evidence yet, but we can speculate from several aspects.

1. Short-term improvement : The stimulating effect of caffeine can indeed improve people's attention and thinking ability in a short period of time, but this is not a long-term solution. Long-term reliance on coffee to improve learning efficiency may cause students to lose the ability to adjust and improve themselves.

2. Long-term effects are unknown : Although there is no direct evidence that coffee affects IQ, long-term and excessive coffee consumption may have a certain impact on students' nervous system, which requires further attention and research.

3. How do junior high school students treat coffee?

How should junior high school students treat coffee?

1. Drink in moderation : When you feel tired occasionally, you can drink coffee in moderation, but be sure to control the amount and not drink too much.

2. Pay attention to time : Try to avoid drinking coffee at night or before going to bed to avoid affecting your sleep.

3. Individual differences : Different students have different sensitivities to coffee, so they should drink coffee according to their own physical conditions.

4. Dependence psychology : To overcome the dependence on coffee, learn to improve learning efficiency by arranging time reasonably, adjusting learning methods, etc.

4. Concerns from parents and schools

Faced with the pressure of the high school entrance examination, parents and schools should pay attention to students' learning status and guide them to correctly view the role of coffee. They should not exaggerate the role of coffee, nor should they completely prohibit students from drinking coffee. Instead, they should educate students on how to use coffee scientifically and reasonably, cultivate their self-adjustment ability, and improve their ability to withstand stress.

The impact of coffee on the physical and IQ of junior high school students is a complex issue that requires our attention and discussion from multiple angles. As students and parents, we should look at the role of coffee rationally, drink it in moderation, and use it scientifically. Schools and society should also strengthen relevant education to guide students to grow up healthily.
