Phototherapy, Light and Health – All Posts

Increasingly the health benefits of light are being appreciated and verified in the scientific literature. Whilst many people know that ultraviolet produces vitamin D in the skin, few realise that for much of the day and most of the year the sunlight contains too little UVB to make vitamin D. Recent research shows that ultraviolet light also releases nitric oxide and reduces blood pressure. The harmful effects of ultraviolet light are mitigated by certain foods that protect the skin. Finally, visible light, and especially red light is proving to have remarkable healing effects on the skin, hair, muscles, brain and eyes.

Neanderthal Herbal Medicine

Our closest, extinct, cousins the Neanderthals are often thought of as thuggish and unsophisticated, but evidence over the last decade has began to challenge this picture, indicating that they had a broad range of skills, knowledge and, yes, sensitivity.

There is a lot of evidence from bone assemblages that Neanderthals often behaved as top predators, hunting a wide range of animals including deer, rhinoceroses, bisons and even brown bear. In this pursuit they were highly skilled and more successful than hyenas with whom they competed, indicating a high level of strategic intelligence and cooperation.

Skeletons excavated in the 1950’s from Shanidar cave in northern Iraq indicate that Neanderthals buried their dead with flowers.
