[stylist] off-topic, circadian cycles

[Homme, James]

Hi,
I can definitely tell you that I feel much more cheerful when I go outside immediately. I work in an area that is away from windows. I have light perception. I can feel a difference in my mood. This happens especially in the winter.

Jim

But I think one's system can just be off just because that's the way one was
made.  I understand what you're saying and it does seem to hold true.  I
know since I lost what little vision I had, I seem tired all the time
because I don't see the sun to make me feel alert.
But some people just seem to be off.  I'm a bit like Bridget in that I'd
love to be able to stay up later and get up later because I've always found
night time such an enchanting time for thinking and writing.

Hi Barbara,

The compound melatonin controls the human circadian sleep cycle. It is
produced in the pinneal gland in the brain, and it's production is triggered
through the reception of light in the eyes during the normal course of
day/night. Many totally blind people have irregular or no melatonin
production, depending on their eye condition and whether or not the rods and
cones in the retina are picking up any light, and hence suffer insomnia or
irregular sleep patterns. A lack of melatonin is also associated with mild
depression.

A few years after I lost my sight a friend, who happens to be a
psychiatrist, told me about this phenomena. I've been taking a melatonin
supplement ever since and my sleep patterns, while not perfect, are much
better than they were.
