No coffee between 8 and 9

No coffee between 8 and 9

Hardly fallen out of bed in the morning, you like to have the first coffee to wake up.

However, this is counterproductive!

Our biological clock (Circadian rhythm), for example, regulates the release of the stress hormone cortisol. The higher the cortisol concentration in the blood, the more awake we are. Between 8 and 9 o’clock in the morning, the cortisol reaches a peak, or in the first hour after waking up. Canadian scientists have found that the high cortisol value can counteract the effect of caffeine. At the very least, caffeine does not enhance the effect of cortisol. The same is true also between 12 and 13 o’clock, as well as between 17:30 and 18:30.

Still a very few hours a day for drinking coffee 🙂
