Chris McCullough  asked the Naked Scientists:
   
I am a policeman and often work night shifts finishing up at 6am. I never feel sleepy behind the wheel but on Sunday morning, driving home, there was a blizzard with snow seeming to fly towards the windscreen of my car.

The effect of the snow was to make me really tired to the point where I was finding my eyes heavy and needed to pull over for 5 minutes.

Could the visual impact of the snow have been making me more sleepy than usual?

Thanks,
Chris

P.S Love the show, keep up the good work!
What do you think?

It is a long time since I last drove in a blizzard but I can confirm the effect is real
