When Michael Chapp, COO at Oura, travels, he notices light’s negative impact on his sleep quality. To regulate people’s circadian rhythm, keeping light out when sleeping and getting light first thing in the morning is essential. Chapp began using the Somo Sleep Fitness Mask a couple of years back to block out light when needed and says it’s a game changer. “It’s really comfortable and designed with a dome shape to promote airflow and minimize disturbances,” Chapp says. “For those looking to get better sleep—especially when traveling—I couldn’t recommend it more.”
