I can't even remember the last time I had a nosebleed... I'm quite squeamish, especially with my own blood, so, I take extra care. Even when a Doctor had to take a blood sample from my finger and it started bleeding, I just feel sick as a dog.
Yes due to a wound inside my nasal area I've been suffering nasty nose bleeds whenever I blow out some air too quickly or get a punch around the wound, which makes blood just come gushing out and make me dizzy whilst slowing down the healing process.. :/
I got a few every now and then when I was younger, but not anymore. There was never any specific type of situation, temperature or climate, it just started to bleed all of a sudden for no apparent reason.
I've actually never gotten a nosebleed. My sister gets nosebleeds every time the season changes. She'll also get them if her nose is hit in any sort of way, even if it's not that hard. I guess my blood vessels are... strong or something? I guess the only way I'd ever get a nosebleed is if I get in a fistfight, which is highly unlikely.
I get a pretty good amount during the Winter. One year it was so bad, I had to get a humidifier, and ever since, really has helped me. I turn it on when I'm sleeping, and even helps with nose congestion.
I used to get nosebleeds a lot, one of my brothers does too.
They used to be pretty bad in elementary school, but after a few times, the school nurse taught me how to stop them pretty quickly.
I still get them maybe once every couple months or so.
