This is a weird thought I had at 5am this morning when I couldn’t get back to sleep. I found myself early this morning lying in bed engaged in, rather than sleeping soundly, thinking, thinking, and more thinking. I thought about work, art, artists, philosophy, food, coffee, chocolate, my children, my week to come, parents’ evening (what I was going to attend this evening), Zumba (another activity of today), the cat, science, religion and the sea.

After an hour of constant thinking I gave up and made myself a coffee and an egg buttie so I could think and eat at the same time, and read my book (a book about philosophy).

I’ve been plagued sporadically with insomnia all my life. Even as a child and a teenager I can remember lying in bed thinking and not sleeping. Luckily, I am generally only plagued by sleeplessness about once a month, but when the plague hits me, it hits me hard.

So my weird thought is: do people who think a lot sleep badly? Do we all spend the same amount of time thinking? Do I think as much as the man stood next to me in the Post Office queue, as David Cameron, as the milkman, as my eldest child? Is thinking a constant for everyone? I suspect not. I think people who think too much can’t sleep.

Interestingly, if you google ‘high IQ and insomnia’ you get some interesting results that claims that on average, people who suffer from insomnia may have a higher IQ. However, my theory is not based on intelligence. It is based on thinking. I don’t think you need to have a high IQ in order to be a thinker. I’m sure there are some very chilled people with a very high IQ who sleep like babies – I’m married to such a person. Equally, I think there are some very clever people who don’t bother their brain with thinking too much.

This article claims that night owls are likely to be more intelligent than morning larks. Poppy cock I reckon. But then I would say that, I’m a morning lark. This article thinks that ‘creative geniuses’ are plagued with sleep issues. Of course that must be true, I say.

However, whether sleeplessness is related to cognitive ability I couldn’t possibly say, but I do believe that those who suffer from excessive thinking are more likely to be lying awake at 2am.
