I knew a man that was nocturnal.

I arrived in LA, at our Hollywood Grandma's house and her new roommate, Ginger Rogers comeback partner (oh, the stories they both could tell) was fast asleep and hadn't got up yet. It was 4pm, and no, he wasnt jetlagged like me. 'Where's Jim' I say, 'Oh he hasn't got up yet, you see he's nocturnal, hes spent so much of his life in show business his body clock is diffetent to ours'.

Thanks to Jodie Salt for this article title nudge!

I don't know if theres science behind it, or even if theres any articles but being in theatre, or just teaching dance afterschool definitely appears to change your body clock.

Before I had kids, (and they do actually sleep, but toddler tired is a whole new level of tired) I was not someone who woke up early, the complete opposite to Sam, whos happily up at 4.45am. I used to work late into the night, I found I was productive at 11pm. My mum, also an ex professional dancer also never used to go to bed early either!

Now from observation this is the reason I think that our bodies as dancers or dance teachers change timezones.

• Performing (and teaching is a sort of performing) releases adrenaline. This stimulates the brain, making you feel more awake and mentally active when you should be winding down.

• Eating Schedules are all over the place. Usually eat dinner at 7pm? Oh nope you cant do that its the opening number/grade 5 modern. So therefore if you eat after the show or teaching both exercise and digestion generate heat. Since your body needs to cool down slightly to fall asleep, eating soon after intense exercise can delay this natural drop in temperature.

• Inside dance studios or theatres is dark, this can mess up your circadian rhythm which alters your body clocks.

The body adapts best when:

• Sleep and wake times are consistent.

• Meal times are regular.

• Light exposure is managed.

Now, you tell me, if being a performer or a dance teacher allows for any of them?

But does it matter? If youre motivated at 4pm and not 9am - cool. If you prefer to work from 9pm-11pm - cool. Plan ahead with your meals. Remember, a regular wake-up time is often more important for regulating your body clock than a perfectly regular bedtime. And get outside for some daylight whenever you can.

Oh and be more Jim. (Jim Taylor for reference, http://www.dancehistoryproject.org/index-of-artists/jim-taylor/)
