1. Increase the burden on the heart. Red bull contains high potassium and sodium ions, and also contains components that promote adrenaline secretion. After drinking, the heart rate often increases and blood pressure increases. If the heart function is poor, it is not recommended to drink it, so as not to cause diseases.

2. Causing hypokalemia. Red Bull is a functional drink, which is mainly aimed at athletes and can replenish a lot of potassium and sodium ions lost due to exercise. Normal people often have high potassium and sodium ions in their bodies without a lot of exercise, and it is easy to have hyperkalemia after drinking this drink for a long time.

3. Accumulate preservatives in the body. Such drinks need to be preserved for a long time, so preservatives are indispensable. Long-term drinking will lead to the fact that preservatives in the body cannot be decomposed and excreted in time, and accumulation in the body will harm health.

4, damage to vision. A large intake of caffeine will lead to optic nerve swelling, which will lead to decreased vision and increase the risk of glaucoma.

5, causing insomnia. A large intake of caffeine can stimulate nerves, resist fatigue and refresh the mind, but it also has disadvantages. Drinking it at night will cause insomnia.
