If someone in your family is getting frequent nosebleeds, it could be due to poor indoor air quality in your home—specifically low humidity.
According to the Mayo Clinic, the two main causes of nosebleeds are dry air and nose picking. Most nosebleeds are minor, but you should seek medical care if bleeding lasts more than 30 minutes or interferes with breathing.
Nosebleeds tend to occur more in the winter in dry, cold climates. Heating your home dries out the air, which dries out your nasal membranes and makes you more susceptible to bleeding and infections. Low humidity also makes you more likely to get the viruses and infections that repeatedly irritate your nasal passage and cause frequent nosebleeds.
"Low humidity can make you more susceptible to catching cold or flu viruses. Air that is too dry dries out your nasal membranes and makes the lining of your nose more susceptible to bleeding and infections. Also, low levels of humidity have been linked to the speedier progression and transmission of viruses in the air." -Department of Microbiology, Mount Sinai School of Medicine article, “Influenza Virus Transmission Is Dependent on Relative Humidity and Temperature,” 2007
Adding moisture to the air with an Aprilaire Whole-Home Humidifier can keep your nose from drying out and prevent bloody noses. It can also make you less likely to get the viruses and infections that cause repeated irritation and ultimately, nosebleeds.
"Humidity reduces the incidence of respiratory infections and speeds recovery from the common cold." -William J. Hitschler, MD, Archives of Otolaryngology.
