The Only 9-5 To Consider

We’ll leave the discussion on why you should quit your day job and get out of the 9am – 5pm rat race for another day.  For now, we’ll look at new research that strengthens the case for embracing a 9pm – 5am sleep schedule.

Other than total sleep duration, research has suggested that your bed-time is more important than your wake-up time for health and body composition.  The old adage, ‘every hour before midnight equals two hours’ may have no scientific support, and ‘nothing good happens after 10pm’ is obviously not true, but it’s pretty clear that hitting the sack early makes a difference.

As far as wake-up times go, there’s been no correlation with body composition, although researchers have identified a greater positive affect in earlier risers.  From strictly a productivity and lifestyle perspective, the early morning provides a quiet uninterrupted atmosphere.  This not only shortens the to-do list and potentially checks off the MITs (Most Important Tasks), but it promotes healthier relationships as a clear mind is less distracted and impatient, and more likely to live in the ‘now.’

The reason for this post was a recent study in the journal PLos ONE that found a lower BMI (Body Mass Index) in those exposed to bright light earlier in the day.  The Senior Author in the study writes:

“The message is that you should get more bright light between 8a.m. and noon.”

We know that evening light (especially from electronics) can lead to poor sleep and fat accumulation, but perhaps we should be increasing our light in the morning as much as we’re decreasing it in the evening? 

It definitely makes a case for doing your 30min walk as soon as the sun comes up!
