A few glasses of beer make you sleepy, but this is not only due to the alcohol. While many types of alcohol can have a stimulating effect, a beer in the evening has a calming effect and promotes sleep.

The beer gets its bitter taste from the bitter substances and essential oils of the hops (cumulus lucullus). In the 19th century, it was discovered that hops have a calming effect on the organism and the nerves.

So far, the medicinal effect of hops has not been sufficiently clarified, which is why the petals of the hop umbel are only included in sleep-inducing medicines in combination with other calming herbs such as valerian or lemon balm.
