Can you drink coffee if you have anxiety disorder?

As mentioned before, drinks containing caffeine should be avoided as much as possible. But this does not mean that you cannot drink coffee and tea if you have anxiety. We can even use coffee to help us take a controllable lunch break.

The principle of coffee refreshing

After people exercise, their cells metabolize a substance called adenosine. One side effect of adenosine is that it can accumulate in the brain and induce drowsiness in the brain. Caffeine prevents adenosine from functioning, which is equivalent to deceiving the brain as if adenosine is not present, thus eliminating drowsiness. When caffeine is metabolized by the body, since adenosine is always present, drowsiness will reappear.

Get a feel for the half-life of caffeine

Caffeine concentration in the human body decreases by half every 4-6 hours. Medically, it is recommended that each person drink no more than 400mg of caffeine per day (24-hour cycle). Of course, those who are heavier can drink more.

Here’s a little taste of it: Extra Large Cup of Starbucks American – 300mg Caffeine； Extra large Starbucks latte - 150mg caffeine ； Grande Starbucks American – 225mg caffeine ； 10 cans of Coke - 400mg.

So, you only need to drink enough when you wake up in the morning, drink half at noon, and don’t drink at night. In fact, it will be fine. If you're worried about getting too excited but still crave coffee, drink less or opt for decaf.

The magical use of coffee to control your lunch break

If you don't get enough sleep at night, but want to supplement your sleep with a nap, it is recommended to limit your nap to 30 minutes. You can drink a glass of Americano before going to bed. Be sure to control it below 200mg and let it take effect after 30 minutes, just when you have finished your rest. Mixed coffee (latte, cappuccino) is absorbed faster than American coffee, so try not to use it in this scenario.
