Since the dawn of time, humans have worshipped the sun. And with good reason. Our biology is set up to work in partnership with it. From our sleep cycles to our immune systems and our mental health, access to daylight is crucial for living a happy and fulfilling life. Our bodies and our brains are designed to function during the day and rest at night. But as more of us move into light-polluted cities, spending our days in dim offices and our evenings watching brightly lit screens, we are in danger of losing something vital: our connection to the star that gave us life. It’s a loss that could have far-reaching consequences for our health.
Listen to Dr. Rangan Chatterjee chat to award-winning journalist, Linda Geddes discussing just what those health implications are.
