Back at a biohacking retreat I attended a few years ago, I picked up an interesting trick that has had a remarkable impact on my sleep quality. By turning my iPhone screen red, I’ve been able to minimize my exposure to harmful blue light before bedtime. This simple adjustment has resulted in significant improvements in my deep sleep, as measured by my Oura ring.

Recently, several people have inquired about the red hue on my iPhone screen, prompting me to share this valuable information with my wider network. I found a detailed article on a website called Block Blue Light that explains precisely how to enable the red screen feature on an iPhone. If you’re interested in trying out this technique for yourself, I highly recommend reading the article: https://www.blockbluelight.com/blogs/news/how-to-turn-your-iphone-screen-red. It provides step-by-step instructions and offers a wealth of information on the benefits of reducing blue light exposure before bedtime.
