Drink your coffee when you wake up? A false good idea, according to scientists

The morning coffee has become a real ritual for some people. Even a necessity. It wakes us up, stimulates us and we love its taste. Some like it short, some like it ultra long . Psychologically, it's the only drink that manages to get us out of bed and the fog that we often experience in the morning. Between its slimming properties and its effectiveness against migraines, there is more than one good reason to consume it. Finally, you still have todrink your coffee at the right time of the day . Between breakfast, the coffee break at 10 a.m., or the one after the meal, not all have the same effects. Steven L. Miller , an American doctoral student in neuroscience, gives us the mistake not to make with your coffee in the morning.

What time to drink your coffee?

To know when it is better to drink your coffee, you have to look at the level of cortisol present in our blood. Depending on the level of this hormone , the effects of caffeine are delivered differently. Caffeine is useless when cortisol spikes . It is when its rate is low that the magic of coffee works. The ideal times to drink coffee are when the "stress hormone" is at its lowest. We therefore prefer coffee breaks between 9:30 a.m. and 11:30 a.m. and between 1:30 p.m. and 5 p.m. . Conversely, we avoid breakfast (between 8 a.m. and 9 a.m.), lunch (between 11:30 a.m. and 1:30 p.m.) and the end of the day (between 5:30 p.m. and 6:30 p.m.).

The impact of cortisol on our coffee break

Known as the "stress hormone" , it is a chemical substance that provides all the energy necessary for our body. It produces more during physical exertion, a moment of stress or upon waking . So you don't need an extra dose of caffeine at these times. Moreover, drinking coffee at these times would only develop a habituation and therefore lessen the long-term effects.
