Acute total sleep deprivation (24 hours) significantly increases plasma levels of serotonin, tryptophan, and taurine compared to normal sleep, potentially explaining the antidepressant effects of sleep loss.
One night of staying awake all night significantly raises levels of serotonin, tryptophan, and taurine in your blood. This chemical shift is linked to why sleep deprivation can sometimes temporarily lift mood (antidepressant effect), but it also disrupts normal metabolic rhythms. Prioritizing regular sleep helps maintain stable neurotransmitter levels and metabolic health.
During sleep deprivation, 27 metabolites (tryptophan, serotonin, taurine, 8 acylcarnitines, 13 glycerophospholipids, and 3 sphingolipids) exhibited significantly increased levels compared with during sleep. The increased levels of serotonin, tryptophan, and taurine may explain the antidepressive effect of acute sleep deprivation and deserve further study.

- Acute sleep deprivation increases plasma levels of specific acylcarnitines (medium- and long-chain saturated), suggesting altered fatty acid oxidation and potential links to fatigue or sleep signaling.Good
- 24 hours of wakefulness reduces the amplitude of daily metabolic rhythms (cosinor amplitude) for the majority of metabolites, particularly those that peak during the day.Good
