Nightshift on a FIFO site is a different animal from nightshift in a city hospital or a 7-Eleven. You're running 12-hour shifts in 45-degree heat, then sleeping in a donga next door to someone else also trying to sleep, in a camp with construction noise, crows, and a dinner bell that goes off at 6pm sharp.
Here's what works when the sun is the enemy.
Why Nightshift Feels Different on Site
Two words: light exposure. At home you can black out a bedroom. On site, dongas have thin curtains, dawn cracks at 4:30am, and every noise echoes through fibro walls. Your body is being told "it's day" by every sensory input while you're trying to convince it it's night.
The second killer is social rhythm. Nightshift eats dinner alone. You miss the pub conversation. You eat crib at 3am in a silent room. Isolation is baked in.
The Sleep Rules That Actually Work
1. Blackout the donga on day one
Bring a roll of gaffer tape and a bin bag. Seal the window. Sounds extreme. Isn't. The 20 minutes you spend the day you arrive saves you three hours of rolling around on day four.
2. Eye mask and ear plugs, non-negotiable
Not the chemist plastic ones. Get the Mack's silicone putty plugs — they actually block the dorm-door slams. Eye mask with a dip over the nose so you can breathe.
3. One caffeine cutoff
Last coffee 6 hours before end of shift. Yes, six. The caffeine half-life is longer than the internet tells you. If shift ends at 6am, last coffee at midnight.
4. Anchor sleep immediately
Don't "wind down" with Netflix for an hour after shift. Eat, shower, lights out. Every 15 minutes you delay is 45 minutes of sleep lost to daytime light creeping in.
5. The nap split
If you can't get 7 hours in one block (you usually can't), split it: 4 hours straight after shift, then a 90-minute nap at 4pm before you start again. Two 4.5-hour blocks beats one ragged 6-hour one.
Eating at Stupid Hours
Your gut hates nightshift more than your brain does. Heavy red meat at 3am sits like a brick and wrecks digestion for days. Switch to lighter crib options: rice, chicken, eggs, fruit. Save the meat for the first meal after shift.
Hydrate constantly — the aircon in most crib rooms runs dry and you'll wake up dehydrated every time.
The Personality Change Is Real
After 10+ nightshifts in a row, something changes. You're slower. Words don't come. Jokes that would've landed two weeks ago now fall flat. You snap at things. You laugh at nothing. People who've only ever done day shift think you're being dramatic — people who've done nights know it's chemical.
This isn't in your head. Chronic sleep debt from rotating shift work is one of the most-studied occupational stressors going. WHO lists it as a probable carcinogen, and the mental health research is damning. If you feel like a different person on nights, it's because, physiologically, you are one.
The Exit Signs
Take a break off nights if you notice: micro-sleeps driving to site, nodding off mid-conversation in crib, rage-responses to small things, or "I just can't get warm." Those are your body waving a white flag. Site medics can usually swap you to day rotation for a swing if you ask early enough.
If you've ever been told "you've changed" after six months of nights, we get it. The Nightshift Is a Personality Now Tee is for anyone whose graveyards have become a personality trait.
