Do serotonin levels drop when you sleep?

Sleep deprivation produced a gradual decline in extracellular serotonin levels, both in the hippocampus and in the frontal cortex. In order to investigate whether the reduction in serotonin was due to other factors than sleep deprivation, i.e. time of day effect, another experiment was performed.

Do serotonin levels fluctuate during the day?

Circulating serotonin levels do seem to oscillate throughout the day [77], but whether they oscillate in the mammalian gut has not yet been determined. Though some bacteria present in the gut can produce serotonin in culture [78], the relative contribution of this to a host's overall serotonin levels are unclear.

What hormone is released when sleeping?

Melatonin, released by the pineal gland , controls your sleep patterns. Levels increase at night time, making you feel sleepy.
