Absurdly Driven looks at the world of business with a skeptical eye and a firmly rooted tongue in cheek. 

I have no idea how they do it.

I've just finished a pleasant dinner with, perhaps, a decent glass of pinot noir thrown in, and I'm walking home.

Suddenly, I hear raucous music. 

I turn and see a plethora of bodies being tortured on bikes, ropes, and various other contraptions of pain in a gym with a blessedly large glass window.

How do people work out late at night? It seems so fundamentally inhuman.

Do they eat afterwards? Do they sleep? How does this affect their ability to work?

Won't they wake up so tired, every muscle aching, that they won't be able to concentrate?

I know that some people like to work late at night. I'm one of them. I wouldn't, though, even consider going to the gym at 9 p.m. and then put in an extra hour or two of writing.

Yet there are those who feel they don't have any other time to keep their bodies alive.

For the longest time, many suspected that these night-exercise types must have trouble getting to sleep after working their bodies into a late-night frenzy.

Now, a new study suggests there really is nothing wrong with late-night gym sessions.

Researchers at Charles Sturt University in Australia wanted to learn whether intense exercise messes with the quality of sleep, thereby wrecking the mind's ability to focus the next day on, well, vital moneymaking activities.

The result of their work is engrossingly entitled: "Evening High‐Intensity Interval Exercise Does Not Disrupt Sleep or Alter Energy Intake Despite Changes in Acylated Ghrelin in Middle‐Aged Men."

The researchers got the same 11 men to exercise at different times of the day. 

What they found were no significant differences in their quality of sleep. 

This seems to contradict the American Academy of Sleep Medicine's advice, which is a touch less certain: 

Typically it is recommended that you should avoid exercising before bed. This is based on the idea that exercise raises your core body temperature, which in theory should make it harder to fall asleep. But research results have been inconsistent.

Still, as the research paper's title suggests, evening exercise did show a decrease in acylated ghrelin -- a hormone that influences appetite and energy levels.

Actually, while we're talking about energy levels, lead researcher Penny Larsen offered another interesting observation

Power output during the sprint efforts was higher for the afternoon and evening trials compared to the morning trial, indicating that participants were able to perform better during latter parts of the day.

Many people listen to their bodies and fall into habits from which it's hard to break.

Perhaps, though, it's worth exploring whether changing your routine might give you the kick you need to think better.

We all need to find ways to think better, don't we?
