Light from devices can be harmful to children—but natural light can offset that. Here’s more about why sunlight matters, and how you can maximize the benefits of fun in the sun
Wednesdays were getting tough for Zenovia Stephens’ family. Her five-year-old son was coming home from school cranky, not wanting to play with his little brother and struggling with the transition. So she ditched her car and began walking him home from school, leaving lots of time for play as they made their way back.
Not all light is created equal. Parents have heard again and again to avoid blue light, and it’s true that exposure to artificial blue light from devices at night can do a number on a child’s daily rhythms. But sunlight is also packed with this much-discussed wavelength, and both types of light have major impacts on a child’s circadian clock.
LeBourgeois explains that the more daytime blue light a person gets, the better defense they have against the harms of evening blue light from screens. She adds that packing the day with sunshine creates a blue-light build-up that helps counteract the consequences of that artificial light at night. In other words, the more sunlight exposure a child gets during the day, the better their brain can build a wall against the harms of artificial blue light later.
