Healthcare workers and nurses who deal with the elderly on a daily basis try to improve the air quality,especially in nursing homes.One of these methods is reducing indoor air quality to help people breathe better.But one respiratory problem persists amongst many elderly.Bronchitis,a common respiratory problem,often occurs in those with sensitive nasal passages and those who smoke.Bronchitis is a virus or bacteria that irritates or inflames the inside of the nose.Elderly people often get bronchitis right after they have had the cold or flu.By reducing exposure to air with many foreign particles and bad habits like smoking,many elderly people can enjoy a healthy life.
