The video explores how blue light from screens can disrupt sleep by affecting the body's circadian rhythm. It explains that ganglion cells in the eyes are sensitive to blue light, which can delay sleep by tricking the body into thinking it's still daylight. While studies suggest a link between blue light exposure and sleep issues, they are mostly observational and not conclusive. Despite this, reducing screen time before bed is recommended. Solutions like blue light filtering software and glasses exist, but their effectiveness is not well-proven. More research is needed to understand and address the impact of blue light on health.
