An espresso after dinner supports digestion, but supplies the body with caffeine that wakes you up.

You can read here whether you should therefore do without it.

Each person metabolizes nutrients differently. Example of body weight: Where some quickly store fat, others stay slim even if they eat all day. There are also huge differences when it comes to caffeine. Some drink three cups of espresso and don't feel anything, and others are already shaky and excited after just one cup.

So if you are one of those who break down caffeine quickly, you can also drink coffee in the evening*?

According to the knowledge portal GEO, the answer is "yes".

Even heavy drinkers would have no problems falling asleep with a late cup of coffee, it is said.

But an American-British study comes to different conclusions.

Stop drinking coffee six hours before bedtime

Cell biologist John O'Neill from the British State Laboratory for Molecular Biology in Cambridge and a team of eight British and US researchers concluded from their study results that coffee later throws the biological clock out of sync. In a study, they examined how caffeine intake in the evening affects the human body. Three hours before bedtime, volunteers were given caffeine capsules equivalent to two cups of espresso (promotional link). The comparison group received placebo. After measuring the melatonin content in the saliva of the study participants, it became clear that the drowsy sleep hormone was released later in the first group. "

” Deutschlandfunk quotes Kenneth Wright, director of the Laboratory for Sleep and Chronobiology at the University of Colorado in the US, where the experiments were conducted.

Neuroscientist Wright therefore advises not to drink caffeinated beverages such as coffee at least six hours before you plan to go to bed

.

According to him, this prevents the internal biological clock from lengthening the daytime phase, which can lead to sleep disorders.
