OIO Bulb helps your body stay on a healthy “sleep-wake” schedule. During the day, it gives off bright blue wavelengths – just like sunlight – to help you feel awake and alert. But at night, it removes those colors because they tell your brain it’s still daytime. Regular lights and screens use the same kind of light your body uses to wake up, which can make it hard to fall asleep. OIO Bulb purposefully removes those colors at night so your body knows it’s time to wind down, rest, and repair. Just like nature intended.
