Why Biohack Your iPhone?
With our lives dominated by screens, our exposure to blue light, especially at night, can wreak havoc on our sleep patterns. The blue light emitted by our devices unfortunately suppresses the production of melatonin, the hormone responsible for regulating the sleep-wake cycle, and tricks our brains to think it’s still daytime. This can cause difficulty falling asleep, restless sleep and poor sleep quality. , Red light on the other hand is the color on the opposite side of the color spectrum and has a minimal impact on the body's production of melatonin. By biohacking your iPhone, and creating a shortcut that helps turn your screen red, you can minimize this disruption and promote better sleep naturally.
How to Make Your iPhone Red?

- Adjust Color Tint: Tap on "Color Tint" and adjust the intensity to your preference, typically maximizing it to 100%.
