This is a YouTube video titled "How to get better sleep." It features Alicia Mackey Huber providing advice on morning light exposure and its effects on sleep quality and eye health, recorded in November 2024.
It's what you do when you first wake up that affects your sleep at night. So when you first wake up, go outside if you can and get just a few minutes of bright sunlight. Sunglasses, regular glasses or contacts stop it from working. And there's a few newer biohackers, like even Andrew Huberman is saying, well, it doesn't matter if you have. No, it does matter, because ultraviolet light is a signal for your eyes. People who get some ultraviolet light, you don't want to cook your eyes in the sun all day long. But some ultraviolet light is associated with having less nearsightedness, so you don't need glasses.
