About this episode

Liz Earle and Rowan Jacobsen discuss the health benefits of sunlight and its impact on aging.

For years we've been told to stay out of the sun to keep us safe, but have we got it all wrong? Award-winning science journalist Rowan Jacobsen joins Liz to discuss how each hour we spend outdoors could actually lower our risk of age-related diseases – and how sunlight deficiency is bad for our health. Liz and Rowan talk about the impact of light exposure on everything from mood and sleep to metabolism and energy, and how our bodies are not designed to live indoors. Rowan also shares surprising data about skin cancer and explains the difference between vitamin D supplements and the vitamin D our bodies produce from sunlight.     In this episode: ·     How healthy sun exposure reduces age-related diseases ·     Why melanoma rates are higher in office workers ·     The importance of sunlight when you’re over 60 ·     The impact of sunlight on your skin microbiome ·     Why a little sun every day is better than two weeks on a beach ·     Can supplements replace sun-derived vitamin D?   Links mentioned in this episode…
