Yes, there really is a good time to drink coffee. A recent video released by AsapSCIENCE revealed that drinking a cup of coffee right when you wake up does little to maximize our alertness and energy levels. Cortisol, also known as the stress hormone, regulates our internal clock or our circadian rhythm. This hormone is what causes us to feel more awake. Between 8 and 9 a.m., cortisol levels peak, which is why we naturally wake up at this time. Drinking caffeinated drinks during this peak actually hinders your alertness in the long run. This is due to the fact that your body becomes used to these high levels making your
caffeine buzz less effective. Therefore, when your cortisol decreases, it is followed by a severe lack of energy. Drinking your coffee after your cortisol peak at 9:00 a.m. will prove to be more beneficial. Cortisol also peaks between 12 and 1 p.m. and between 5:30 and 6:30 p.m. so it is best to drink between these times. For those who have to rise very early, scientists say to wait at least an hour before grabbing the joe in order to experience its full effect.
