Are bodyclocks may not just respond to light...

This artical I found on the net says theres evidence that are body clocks respond to temperture as well but I find it disturbing that it says "temperature was more effective than light in triggering the clock rhythms."

Now this could be the reason why, I respond to light better in the summer, I need less light in the summer then I do in the winter. Even though there is plenty of it in the summer but on some summer weeks if the weathers been dreadfull 30 minties if light does the job but in the winter I need it indeffinantly.

My body temperature seems to be a bit odd- or at least according to my hubby it is.

I generate huge amounts of heat when I'm asleep- to the point where the mr has put his hand on the radiator to check whether it's on... it's not it's just me! But I feel the cold a lot in winter. I'm usually the one wearing my scarf from September to April and I leave it on a work as well.

It might just be a comfort blanket effect!

Mind you if light / sun are the axis of the whole SAD problem then it wouldn't surprise me if temperature was a contributing factor as well. sunlight = warmth (in theory).
If you're conserving energy because of a lack of food (historical context of SAD) then heat would certainly be a trigger as well... being cold, or keeping warm when it is cold uses a lot of energy unless you just curl up and sleep through the cold times.

I think I must be the odd one out.
I'm still walking around in t-shirts while everyone else
has there winter woollies on :?

Or it may be due to the amount of thyroxine I'm on.
I was constantly cold before I started taking it.

Hmm, I'm always frozen, especially hands, feet and bum! Very low blood pressure though all year round. Julie
