The Best Time for Coffee: When It Energizes and When It Harms — Scientists' Opinion

Many people can't imagine their morning without a cup of strong coffee. But it turns out that not only the amount of caffeine, but also the time of its consumption plays a key role. Scientists have explained at what hours the drink really helps the body, and when it can be harmful.

Not immediately after waking up

The first and main myth is to drink coffee right after you wake up. In fact, from 6:00 to 9:00, the body actively produces cortisol - the hormone of vigor. If you add caffeine during this period, it can cause excessive stress on the nervous system and increase anxiety.

The ideal time for the first cup: from 9:30 to 11:30. By this time, cortisol levels decrease, and coffee really begins to work as a stimulant.

The second wave of energy

If you feel an energy decline after lunch, the optimal time for a second portion of coffee is from 1:00 PM to 3:00 PM. Caffeine will help cope with drowsiness without disrupting your evening sleep pattern.

Coffee after 4:00 PM - forbidden

Even if you don't feel the "impact" of coffee, its effect on sleep quality persists. Caffeine can block adenosine - a substance responsible for the feeling of fatigue. As a result, you take longer to fall asleep and sleep less deeply.
