It’s 5 am and you feel like death. Eight hours down and you’ve still got four more to go. With a mind like sludge, a phone rings and you need to sound attentive and informed. This isn’t going to be easy.
Me – I hate night shifts. Hours of dark, unrewarding loneliness accompanied with the odd things your digestive system does at four in the morning. Finishing means collapsing into bed utterly exhausted as the rest of the world enjoys their Cheerios. It is strange experience. Even stranger, is that so many people actually love working at night.
Some people must be better at it than others. Researchers from Bergen, Norway – a country known for very long, dark winters – compiled over 30 years of research to find out what makes a true ‘night worker’. Could this be you? Read on, to see if you are built to work the night shift…
Night working and Health
It is generally thought that working at night is bad for you. Some sleep experts have said that it is as bad as smoking 20 cigarettes a day. Other evidence casts doubt on these headline-grabbing claims. It is more likely is that people who work nights have a tendency to lead less healthy lifestyles and smoke more – rather than the other way around.
So how can you find out whether you are likely to make it through night duty – without resorting to alcohol and nicotine? These are the four factors that the Scandinavian researchers discovered:
- Younger adults tolerate night working best
- Men tend to fare better than women
- Early morning-haters prefer night shifts – People who have a low ‘morningness’(!) score.
- There is some evidence that good night workers possess genetic differences (they have the so-called “healthy shift worker gene”)
Can I really tell if I am suited to night shifts?
This new research effectively works out who the best shift workers are on average (it is a ‘meta-study’) So generalisations are inevitable – I’ve certainly met many a person who enjoyed night shifts that didn’t fit these criteria. As a general guide though, it’s an interesting and useful check-list.
The one way to find out whether you are a true night-worker would be to give it a try. I certainly don’t ever look forward to night shifts in the future.
One question remains: What’s my excuse for struggling so much despite being a fairly young guy, who doesn’t particularly love mornings?
I think I’ll blame it on the genes…
