Overview

Chilblains, also known as pernio, are small patches of inflamed skin. They develop after exposure to air that’s cold or damp (but not freezing). Usually, chilblains form on your fingers or toes.

Chilblains are typically red, bluish or purplish. They may feel itchy, tender or painful.

Anyone can get chilblains, but people with a low body mass index (BMI) have a higher risk of developing them.

Babies can get chilblains as well if they’re not wearing proper clothing in damp or cold weather.

It can be frustrating to get tender, inflamed patches of skin when the temperature drops — especially on visible places like your hands. But know that there are steps you can take to try to prevent them. Your healthcare provider can offer medications, as well.

Complications

Blood clots are a dangerous complication of atrial fibrillation (AFib). Blood clots can lead to stroke.
The risk of stroke from AFib increases as you grow older. Other health conditions also may increase the risk of a stroke due to AFib. These conditions include:
  • High blood pressure.
  • Diabetes.
  • Heart failure.
  • Some types of heart valve disease.
Blood thinners are commonly prescribed to prevent blood clots and strokes in people with atrial fibrillation.

Prevention

Healthy lifestyle choices can reduce the risk of heart disease and may prevent atrial fibrillation (AFib). Here are some basic heart-healthy tips:
  • Control high blood pressure, high cholesterol and diabetes.
  • Don't smoke or use tobacco.
  • Eat a diet that's low in salt and saturated fat.
  • Exercise at least 30 minutes a day on most days of the week unless your health care team says not to.
  • Get good sleep. Adults should aim for 7 to 9 hours daily.
  • Maintain a healthy weight.
  • Reduce and manage stress.
