According to a study published in the August 1st issue of the journal SLEEP, researchers have found that people who work rotating shifts have lower levels of serotonin, a hormone and neurotransmitter in the central nervous system thought to play a big part in regulating a person's sleep.
Levels of serotonin were found to differ greatly between day workers and rotating shift workers, with day workers having significantly higher levels of serotonin.
