Night shift work and rapid time-zone changes disrupt circadian rhythms, leading to increased morbidity, mortality, and cognitive impairment.
If you work night shifts, use bright light exposure during your shift and wear blue-light-blocking glasses on your commute home. Prioritize a dark, quiet sleeping environment during the day. Be aware that long-term night work increases health risks, so monitor your health closely.

In general, night shift work of any kind and duration increases morbidity and mortality, negatively impacting both physiological and psychological health.
Why this rating
Supported by multiple studies on shift workers, including nurses and military personnel.
