Can I go out for exercise on hazy days?

Hello, exercise in hazy days is very harmful to the human body. Running is an aerobic exercise, and hazy days will increase the amount of harmful substances inhaled. Moreover, the particles in the haze are sedimentary particles and cannot be eliminated from the body. Therefore, it is recommended that you use a treadmill at home or use a treadmill in the gym to maintain endurance. You can also use ZRA to purify the air.
