[355] - Blue light does not inhibit you going to sleep, there I said it...

Text me what you thought of the show 😊

I challenge the biggest blue light belief and explain why the real danger is not whether you nod off, but what light does to melatonin and your circadian rhythm. I break down how your eyes feed the brain’s master clock and why managing light is one of the most powerful health tools a shift worker has.
• the two separate eye systems for vision and biology
• how IPRGC cells send light information to the suprachiasmatic nucleus
• why morning daylight anchors cortisol, alertness, temperature and metabolism
• what melatonin really does beyond sleepiness, including repair signalling
• melatonin as an antioxidant and what that means for cellular stress
• circadian disruption and higher cancer risk research in shift workers
• why artificial light at night creates social jet lag and metabolic harm
• practical light rules: sky before screen, warmer evenings, complete darkness for sleep
• why scrolling in bed can shift your body clock and leave you waking tired
