Sunlight is more than a mood boost; it’s a biological signal your body depends on. In this episode of Pause Here, we unpack the science of sunlight and explore what it means to become light-literate: someone who understands how different types of light shape sleep, mood, hormones, cognition, and your overall health.
From UVB-driven vitamin D to the circadian power of morning light to the calming warmth of infrared, sunlight is constantly shaping your biology - whether you realise it or not. We explore how geography and seasons change the way light works on your body, how architecture and design can actually improve healing through daylight, and what happens when we don’t get enough light (hello, winter blues).
Step into the science of sunlight and learn how to let light lead the way to better sleep, steadier moods, and a more balanced day.
