Spring is in the air, the clocks have sprung forward, and each day has slightly more sunshiny hours than the last... but you are on a string of nights, trying to avoid the siren’s call of a verdant spring day and get some much needed rest. Sleep plays a key role in your mental, physical, and emotional wellbeing and allows you to perform at your clinical best. One landmark study demonstrated that after only 17-19 hours without sleep, subjects’ performance was equivalent or worse than those with a BAC of 0.05% and after 28 hours performance was similar to a BAC of 0.1%.
Whether you are working days, nights, or somewhere in between, getting adequate restful sleep can be challenging. However, even if your schedule doesn’t permit increasing your hours of sleep per night, by incorporating some of the basic sleep hygiene principles below you may be able to significantly improve your sleep quality.
Tips for Sleeping during Shift Work:
- Beds are for sleeping, not working
- Keep your bedroom quiet, dark, and cool
- Avoid using/looking at electronic devices near bedtime[2,3] (or at least limit you exposure to blue light with iPhone night shift or f.lux)
- Decrease or even avoid evening alcohol consumption
- Try sleep focused meditation
- Get some daily exercise (but not right before bed)
- Expose yourself to bright light when waking up, and avoid before bed
- Shift switching? Take a late afternoon nap for at least 2 hours
- Can’t sleep after 30 min, get up and do something else (see tip 5)
