Why are you tired?
Blame your smartphone. Not because the blue light it emits is keeping you awake… it’s because it makes you breathe less deeply! Scientists found that people who used their phones for more than 4 hours a day had lung function that was over 30% lower than those who used their phones less. And just so you know, the average teenager is on their phone 6 hours a day, so 4 hours isn't a crazy amount!So why would phone use lead to poor lung function? Because we hunch our shoulders and bend our necks when using our phones. So our airway is restricted and we’re not fully expanding our lungs. As a result, we breathe more shallowly.
