Chemicals called neurotransmitters send messages to different nerve cells in the brain. Nerve cells in the brainstem release neurotransmitters. These include norepinephrine, histamine, and serotonin. Neurotransmitters act on parts of the brain to keep it alert and working well while you are awake.
Other nerve cells stop the messages that tell you to stay awake. This causes you to feel sleepy. One chemical involved in that process is called adenosine. Caffeine promotes wakefulness by blocking the receptors to adenosine. Adenosine seems to work by slowly building up in your blood when you are awake.
This makes you drowsy. While you sleep, the chemical slowly dissipates. The role of serotonin beyond the central nervous system during embryogenesis. Front Cell Neurosci. Indigenous bacteria from the gut microbiota regulate host serotonin biosynthesis.

Updated February 1, B enzodiazepines are a family of molecules, some of which are used as sleep-inducing medications, while others are used as tranquillizers. Thus benzodiazepines promote sleep by augmenting this natural process.
The same GABAergic receptor also has binding sites that can be used both by barbiturates a class of drugs once commonly used as sleep aids but now almost never used for that purpose and by anaesthetics, whose purpose is to put surgical patients to sleep. Getting high-quality sleep is essential to wellness.
