Does hair matter?

I’ve had several people ask whether it would be better to fit or shave off their hair so that the transcranial light device can penetrate further into the brain tissue.

I am a great fan of head hair. It looks lovely, feels nice and most importantly, it keeps your head warm. The has a lot of blood vessels close the to surface of the skin and being bald means that a lot of heat can be lost through the head. Hair serves a useful biological function as well as being of aesthetic value.

I would not recommend removing your hair, unless you have so little hair that the removal of the last strands will make no difference. If this is the case, then why bother! Keep those gorgeous strands.

Some people find that their head hair starts to regrow. Where there had been a shiny, bald pate, fuzz has started to appear. A comb may be required. Those remaining gorgeous strands might just proliferate. Don’t argue!

If you have a lot of hair, then flaunt it and enjoy it. Don’t cut it off or shave it off. You will still get red and near infrared light onto your brain cells. Remember that photobiomodulation works by the indirect effect as well as the direct effect.

Sleep

Matthew Walker’s book Why We Sleep is a very good read. He writes beautifully and with well-argued clarity.

Prof Walker gives very compelling evidence that sleep is not an optional human behaviour – that if we want to live well and live long, then ensuring a good night’s sleep (every night and without drugs) will make that more possible.

Interest in Apathy – at last!

The more I observe people with Parkinson’s disease using photobiomodulation, the more astonishing and wonderful it is to see the positive effect of daily lights on the significant and debilitating symptom of apathy.

Covid-19 and Parkinsonism

If things weren’t already frightening enough thanks to the pandemic, with the number of new cases climbing, and even more people dying, along comes a journal article that is rather disconcerting.

It is called Parkinsonism as a Third Wave of the COVID-19 Pandemic? I didn’t put the question mark at the end of the article title – this was placed there by the Melbourne-based authors. It is a question, a realistic and one that has to be faced and planned for.

Mental clarity vs brain fog

The term brain fog is not an official medical term, but we all know what it means, and we have all experienced it. Serious and creative thinking is hard enough to do at the best of times, but when brain fog descends, it is even more difficult. Unfortunately brain foggery seems to happen more often as we get older which is even more frustrating…
