What time of day does serotonin peak?
The serotonin levels were measured by ELISA every hour at night (20:00-08:00 h) and every 4 h during the daytime (08:00-20:00 h). Ours results show that the maximum levels of serotonin in plasma were obtained at 09:00 and 22:00 and a minor peak at 01:00 h.

Does dopamine drop at night?
When dopamine then interacts with its receptors, it inhibits the effects of norepinephrine -- which means a decrease in the production and release of melatonin.
