Night Shift Work: How to Sleep Well and Stay Healthy While Working at Night

People who work night shifts and need to rest during the day sleep less and worse. Furthermore, the hormones melatonin and cortisol, as well as salivary inflammatory cytokines, experience dysregulation in their production, which can be an indicator of various diseases.

Humans were not designed to work at night. Our physiology is programmed so that we sleep when it's dark and wake up when it's light. Whenever we try to reverse this pattern, we end up going against the nature of our circadian rhythms.

Due to exposure to light at night, the bodies of those who work night shifts secrete less of the hormone melatonin, which is involved in controlling biological rhythms, including the one that regulates sleep.

In other words, the change in the amount of melatonin in the body also alters the "clock" by which the body tells it's time to sleep. The darker and quieter an environment, the more melatonin tends to be secreted and the sleepier the person becomes. Cortisol secretion in these workers, in turn, has lost its natural rhythm.

This doesn't mean you shouldn't work at night; here you'll learn how night workers can better take care of their health.
