You can communicate with them more. Can roommates be in the same dormitory? There is no need to quarrel about these trifles. Chatting more can solve it. The only way to prevent the harm of passive smoking is isolation. In fact, I have encountered many such problems and smoked a lot of second-hand smoke. I don't think it is possible to escape from the same studio, but opening the big window for ventilation is an effective way!

Vitamin C supplementation not only helps smokers quit smoking, but also helps the harm caused by passive smoking. Because vitamin C, as a powerful antioxidant, can neutralize oxygen free radicals that cause cell damage in the human body, people who smoke passively will reduce vitamin C, so vitamin C supplementation is a good way to eat more fruits and vegetables. Of course, if you think passive smoking is a lot, there is nothing wrong with buying vitamin C tablets and AD capsules!

The suggestions are: first, escape. Second, ventilation. Third, supplement vitamin C.
