As a kid, I dealt with bloody noses on a regular basis. Any time the weather shifted, hot as well as cold temperatures changed on a sizable scale, or the atmosphere was super dry, I bled. It was just a thing. It happened almost bi weekly in some cases. There was never any time for it; it would even happen in the middle of the night. However, they were worse in the colder weeks. With the outside being so cold, the air was dry. Inside, it was warm, however again dry. I would have troubles a lot in the winter. All of us knew it was because of the dry air. Finally, the two of us bought a humidifier- which help to add moisture to the air- to help out the air issue. The humidifier came on various times a morning (it was on a timer as well as would get shut off before bed each night) as well as worked in tandem with the gas furnace to prevent the air from drying out too badly. It helped prevent my troubles; I started to have bloody noses less as well as less. It also kept most people from having dry throats, which was another regular issue at that time of year. Not because the two of us were sick, however because of the dry air. The humidifier was also a blessing while in the summer. Even though it was war outside, the home still would get dry from the air conditioner. My nose concern would peak again in summer time due to the hot as well as cold temperatures, so the humidifier was a blessing in that. I thoroughly request a humidifier to prevent dryness- no matter what temperature you are in.
