From bad sleep, wrinkles and irritable kids - the weird complications of air pollution exposure
We all know that the thick clouds of smog which have been hovering above the northeast of America can cause an itchy throat, coughing and stinging eyes but some may also be suffering from the lesser-known symptoms.
Dr Gregory Wu, a critical care doctor at Albany Medical Center in New York, has revealed the weird warning signs that air pollution is damaging your health.
He said that when the smog gets into the lungs and causes inflammation, it can lead to anything from trouble sleeping to wrinkles and even irritable children.
About 50 million Americans are still under air pollution warnings across the US as wildfires in Canada cause swaths of smog to fill the air.
Dr Wu told NBC News: 'Even if you are healthy, you may feel some effects.
'We do encourage folks, if they are having chest pain or chest tightness, that they should be seeking care.
'And similarly, if folks are having headaches or dizziness, that's another good reason to seek care or at least get indoors.'
One of the top effects of smog that Dr Wu mentioned was its ability to throw off your sleep.
