1. Make trouble when you are nervous
Caffeine improves alertness, sensitivity, memory and concentration. But drinking more coffee than you are used to drinking will produce a similar dose of stimulants, which can cause nervousness. For people prone to anxiety disorders, caffeine can worsen symptoms such as palmar sweating, palpitations, and tinnitus.
2. Aggravating hypertension
Because of its analgesic effect, caffeine is often compounded with other simple painkillers. However, if you take a large amount of caffeine for a long time, if you already have high blood pressure, using a large amount of caffeine will only make your situation worse.

A study has shown that after drinking a cup of coffee, blood pressure can rise for up to 12 hours.

These conditions, together with a large amount of caffeine, may pose a threat to bone. If you can enjoy it in a reasonable amount, you can still stop eating because of choking.
