According to a British media report, neuroscientists at the University of Health Sciences Unified Service in Maryland in the United States have calculated that the best time to drink coffee every day is at 9: 00 am, 30: 11, 11: 30. This is because the interaction between caffeine and an important hormone in the body (cortisol, also known as hydrocortisone) is optimal during this period of time. Cortisol helps the body regulate its own biological clock and improve alertness. Cortisol levels peak shortly after people wake up, and the peak lasts for up to an hour, averaging between 8: 00 and 9: 00 in the morning. The researchers believe that drinking coffee after this peak is better because it boosts the production of cortisol when it decreases.

In addition, drinking coffee at the highest levels of corticosteroids in the body produces a tolerance to caffeine, so that only drinking more coffee can have a refreshing effect. There is a similar view in pharmacology that drugs are taken when they are most needed, otherwise the body will develop drug resistance. In other words, the refreshing effect of drinking coffee at breakfast is not significant.

Although cortisol levels peak between 8 a.m. and 9 a.m., cortisol levels peak again between 12:00 and 1 p.m. and at 5 p.m., the researchers said. In addition, the content of cortisol in the human body will also be related to people's physique and schedule, so people who get up late should drink coffee later.
