As a kid, I dealt with bloody noses on a regular basis. Any time the weather shifted, temperatures changed on a large scale, or the atmosphere was super dry, I bled. It was just a thing. It happened almost daily in some cases. There was never any time for it; it would even happen in the middle of the evening. However, they were worse in the colder weeks. With the outside being so cold, the air was dry. Inside, it was warm, but again dry. I would have complications a lot in the winter. We knew it was because of the dry air. Finally, we obtained a humidifier- which help to add moisture to the air- to help out the air issue. The humidifier came on many times a afternoon (it was on a timer and would get shut off before bed each evening) and worked in tandem with the oil furnace to prevent the air from drying out too badly. It helped prevent our complications; I started to have bloody noses less and less. It also kept most people from having dry throats, which was another typical issue at that time of year. Not because we were sick, but because of the dry air. The humidifier was also a blessing during the summer. Even though it was war outside, the beach house still would get dry from the a/c. My nose problem would peak again in summer time due to the temperatures, so the humidifier was a blessing in that. I thoroughly suggest a humidifier to prevent dryness- no matter what climate you are in.
