About this episode

The episode discusses the impact of light on sleep, mood, energy, and aging, featuring insights from Dr Nichola.

We’re shining a light on light itself: how natural daylight, vitamin D, and different light spectrums affect your sleep, your mood, your energy, and yes, how quickly you age. Dr Nichola explains the science behind why your body is designed to run on a cycle, how the sun impacts your internal clock, and what happens when artificial light, shift work, and screens throw that rhythm off balance. She also explores the evidence behind light lamps and red light therapy, plus suggests some simple steps you can take to support your biology from the inside out.
