Renowned evolutionary biologist Theodosius Dobzhansky said “nothing in biology makes sense except in the light of evolution.” Throughout our evolution, we have lived in daily cycles of light and dark. These cycles have led to the development of natural circadian rhythms that impact many aspects of our health and vitality.
Circadian rhythms are triggered by the bright light stimulus in the morning and darkness in the evening. The hypothalamus area of the brain – specifically the suprachiasmatic nucleus (SCN) – is the master regulator, synchronising the body’s circadian clock based on information it receives from photoreceptors in the eyes in response to light . The impacts of circadian rhythm are wide-reaching:Read More
