How to drink coffee most effectively to refresh yourself? When to drink without affecting sleep?

A question related to drinking coffee is: “How to drink coffee most effectively? When to drink it without affecting sleep?”

Choose the right time to control positive benefits and reduce negative impacts

The refreshing effect of a cup of strong coffee makes people flock to the world, but how to invigorate the spirit and reduce the negative impact on physical health, “drinking time” is the most important determinant.

Under normal sleep conditions, the concentration of cortisol in the body is the highest when you just get up. At this time, the refreshing effect of coffee is not obvious, so you must drink it 2-3 hours after getting up or 2-3 hours after lunch.

Plus, since the caffeine doesn’t kick in until 20-30 minutes after you’ve finished drinking it, you can enjoy a cup of black coffee before heading out and hitch a ride to the office just after a busy day at work.

If you have the habit of taking a lunch break, you can take a nap immediately after drinking coffee, and wake up just to play a boosting effect.

Finally, the half-life of caffeine in the human body is about 4-6 hours. If you don’t want to be disturbed by caffeine, you can drink coffee earlier. For example, bedtime is 10 pm, so you should not drink coffee within 7 hours before going to bed at the latest, which means that you will not drink coffee after 3 pm.
