A smartphone’s camera and flash could help people measure blood oxygen levels at home

Conditions like asthma or COVID-19 make it harder for bodies to absorb oxygen from the lungs. In a proof-of-principle study, University of Washington and University of California San Diego researchers have shown that smartphones are capable of detecting blood oxygen saturation levels down to 70%. This is the lowest value that pulse oximeters should be able to measure, as recommended by the U.S. Food and Drug Administration.

Smartphone Use Associated with Unhealthy Eating and Overweight in Teens

Even moderate smartphone use may influence teens’ diet and weight, according to a new study of more than 53,000 Korean adolescents. Teens who used a smartphone for more than 2 hours per day were significantly more likely to eat more junk food and fewer fruits and vegetables than those spending less time on their phone. Teens spending more than 3 hours per day on a smartphone were significantly more likely to be overweight or obese.

Chula Turns Old Smartphones into 2,500 Microscopes for Schools
