Serotonin is a neurotransmitter that plays a role in regulating mood, sleep, attention, and learning. It is involved in promoting feelings of well-being and happiness, as well as in sleep-wake cycles and cognitive functions such as attention and memory. Imbalances in serotonin levels have been linked to various mood disorders and sleep disturbances.
a neurotransmitter, derived from tryptophan, that is involved in sleep, depression, memory, and other neurological processes.

No. It is a neurotransmitter, derived from the amino acid tryptophan.
The median raphe nucleus is associated with the synthesis and release of serotonin, which is a neurotransmitter involved in mood regulation, sleep-wake cycles, and various physiological functions.
Some chemicals that can induce sleep include melatonin, a hormone produced by the pineal gland; gamma-aminobutyric acid (GABA), an inhibitory neurotransmitter; and adenosine, a byproduct of energy consumption in the brain. These chemicals help promote relaxation and regulate the sleep-wake cycle.
gamma-amino butyric acid
The pineal gland in the brain produces serotonin, a neurotransmitter that is involved in regulating mood, behavior, and sleep.
Serotonin (5-hydroxytryptamine, or 5-HT) is the neurotransmitter associated with reducing anxiety, reducing aggression, reducing appetite, increasing somnolence (sedation and quality of sleep), and reducing depression. A deficiency of this neurotransmitter, or receptor mutations leading to decreased binding affinity of one's own neurotransmitter levels can lead to any of inverse symptoms listed above (depression, anxiety, aggression, increased hunger or overeating, sleep disorders, etc.).
The neurotransmitter known as the "mood molecule" is serotonin. It plays a key role in regulating mood, emotions, and sleep. Imbalances in serotonin levels have been linked to conditions such as depression and anxiety.
Yes. When a person is sleep-deprived or has consistently inadequate sleep, their body begins to secrete the stress hormone cortisol, which increases blood pressure and puts a strain on the cardiovascular system. Over time, this puts a person at a greater risk of heart attack and stroke. However, getting enough sleep keeps cortisol levels down, and can reverse this situation.
A word beginning with R for sleep is rest.
