It turns out that this drink is not recommended to be consumed between 08:00 and 09:00.
Why you shouldn't drink coffee between 8 and 9 in the morning
The reason is that during this time frame, cortisol levels peak. A person feels a surge of energy, starts to feel alert, and is ready to work.
Consuming coffee in this state is essentially pointless.
Moreover, caffeine might even interfere: for instance, it could significantly raise blood pressure.
When to drink coffee
So, we conclude that consuming the popular energizing drink between 08:00 and 09:00 is not advisable.
However, it is perfectly fine to do so between 09:30 and 11:30. This is when the concentration of cortisol begins to decline.
Coffee consumed during this time will be extremely beneficial.
As a result, productivity will return, and a person will feel less fatigued.
