Sleep is the number one cure for crushing fatigue in shift-work environments. Poor sleep dramatically affects hunger hormones — one night of inadequate sleep reduces leptin by 18% and increases ghrelin by 28%, leading to 24% increased hunger and cravings for salty and sweet foods.
Improving Sleep Through Naps
- 20-minute nap: Light sleep boost — try box breathing (4-second inhale, 2-second hold, 4-second exhale)
- 20-minute "Nap-puchino": Drink 8-12 oz coffee or tea before your nap — caffeine kicks in just as you wake up
- 90-minute nap: Aligns with a full sleep cycle to minimize grogginess
Optimizing Your Sleep Environment
- Install blackout shades or curtains
- Cover alarm clocks and lights
- Use earplugs for noise reduction
- Enable night shift or eye comfort shield on devices to reduce blue light
- Establish a consistent pre-bedtime routine: reading, stretching, yoga, or warm showers
What to Avoid Before Bed
- Alcohol (3-4 hours before bed): Impairs sleep quality despite helping you fall asleep faster
- Caffeine (4-6 hours before bed): Disrupts sleep quality even if you can still fall asleep
- Nicotine (3-4 hours before bed): Lengthens sleep onset, increases night waking, reduces deep sleep
Foods That Improve Sleep
- Tart cherry juice (4-16 oz, 1 hour before bed): Improves melatonin availability
- Kiwis (2 pieces, 1 hour before bed): Speeds sleep onset and improves sleep quality
- Fatty fish (6 oz, three times weekly): Enhances sleep quality and daytime productivity
Consider a Sleep Study
A Harvard study of 7,000+ firefighters found that 37% experience sleep disorders — and 80% are unaware they have one. If you regularly sleep under 6 hours, a sleep study is worth considering. These are typically covered by insurance and can often be done at home.
