Dear Suneel Singhji,
Nosebleeds are common during the winter and should not be a cause fort concern.
Cold winter air can be drying and irritating to the nose and so can forms of indoor heat, like forced air and fireplaces. Blood flow from the nose can range from a few drops to a real gusher.
Older individuals are more susceptible to nosebleeds in winter because their mucous membranes are not as lush and the dry air causes the thinning blood vessels in the nose to break.
Older women and people taking blood-thinning drugs face an even greater risk. Women who are postmenopausal are especially vulnerable to nosebleeds because of decrease in estrogen that increases bodily fluids. Anyone who is taking blood thinners like aspirin or Coumadin also is prone to nosebleeds.
If you get a nosebleed, don't panic. Tilt your head back and apply firm pressure to nostrils for about five minutes.
Apply ice. The cold causes blood vessels to constrict, which limits and slows down the blood flow. Put petroleum jelly on cotton pads and insert them into your nostrils. Go to the doctor if bleeding is profuse and does not stop. Bleeding vessel will likely be cauterized, meaning that heat would have been applied to the wound to staunch the flow.
There are few things you can do to prevent winter nosebleeds, too.
Get a humidifier and run it, especially in bedrooms, with door closed, a few hours before going to bed. You will be spending eight hours or so sleeping and your nose needs a soothing rest just like you do.
A dab of petroleum jelly on either side of septum, two times per day, will aid moisture. Saline sprays and specialized gels also are readily available in medical stores.
