According to a researcher in neuroscience, the ideal time to take a morning coffee is between 9:30 to 11:30. It is between these two hours that caffeine has the maximum effect. For many people, coffee is the essential drink for breakfast. The solution of choice to give yourself a little boost from the moment you get up. Still, drinking a cup of coffee immediately after waking up would not be the perfect time to benefit from the effects of caffeine. 

According to the neuroscience researcher, waiting a few hours would be a much better idea. The ideal moment would be between 9.30am and 11.30am. To explain this, you need to know about a particular concept called chronopharmacology, which is based on the principle that a drug will not have the same effect depending on the time it is given. This is because of the different biological rhythms that our body knows. Coffee and more particularly caffeine do not escape this phenomenon. 

Once absorbed, this substance interacts with a key hormone called cortisol, which stimulates the awakening and in particular the release of energy from the reserves of the body. The rate of this hormone produced by the adrenal glands is naturally high soon after waking and peaks around eight to nine hours depending on the time of the sunrise. However, two hours later, between 9:30 and 11:30, this rate decreases. So it is at this time that we should drink coffee. 

Caffeine would then have the effect of stimulating the production of cortisol and thereby its effects. Therefore, a very early morning coffee is less effective. If you drink coffee at a time when the concentration of cortisol in the blood is at its peak, you probably should not drink it. It is because the production of cortisol is closely related to the level of alertness. The peak of cortisol occurs on average between 8 and 9 am in the morning. 

Also, you drink a coffee just when you are already approaching your maximum level of natural vivacity. A coffee drunk as soon as you wake up would not really have any effect. But more than that, it could be counterproductive. One of the key principles of pharmacology is to use a drug when it's needed, otherwise we can develop tolerance to the substance at the same dose. Drinking coffee on awakening could therefore reduce the effects of coffee in the longer term.
