Do you like to have a cup of coffee in the morning to wake up sleepers and double your productivity? But American neuroscientists say it's more important to drink caffeine at the right time if you want it to have the most refreshing effect.

When you get up from 8 to 9 o'clock every day, the body has high levels of cortisol (Cortisol). These hormones play a role in keeping the body awake. When the concentration of cortisol is high, the body does not feel the refreshing effect of caffeine. Instead, it increases the body's tolerance to caffeine, so the next time you want to stay awake, you need to drink more caffeine.

According to the Telegraph, a research report by American psychiatrist Steven Miller pointed out that an hour after people wake up, cortisol begins to drop and the body begins to feel tired, so between 9:30 and 11:30 every morning on average, the caffeine in coffee can stimulate the nerve center and boost energy, while 10:30 is the "prime time"!

Cortisol will also rise again around noon, so you can have another cup of coffee an hour and a half after eating.
