Night shifts and mental health — an Indian worker's guide

BPO employees, healthcare workers, security staff, factory workers and startup teams often treat night shifts as a lifestyle adjustment. The body treats them as a biological negotiation, and sometimes a costly one.

The mental-health effects include insomnia, irritability, low mood, anxiety, brain fog, social isolation and increased reliance on caffeine or alcohol. Rotating shifts are usually harder than stable nights because the circadian system never gets a predictable anchor.

If possible, keep sleep and wake times stable even on off-days. Use bright light during the work night and dark glasses on the commute home. Make the bedroom cold, dark and quiet. Move caffeine to the first half of the shift only. Protect one social ritual weekly so night work does not become social disappearance.

If you cannot sleep more than four to five hours, mood drops for more than two weeks, or you are using substances to force sleep, involve a clinician. Sometimes the correct clinical recommendation is a shift change; health is not infinitely negotiable.
