Lockport Union-Sun & Journal — Winter is here and we have just experienced a severe winter storm. Sudden changes, such as the cold weather we endured last week, as well as the ups and downs in temperature, can have a significant impact on individuals who are elderly or have heart disease.
When the weather is extremely cold, especially if there are high winds, the best bet is to stay indoors. If you do need to go out, make your trip as brief as possible. Exposure to cold temperatures can cause serious or life-threatening health problems, including cardiac complications.
The body’s response to the cold is to increase heart rate and blood pressure, and that in turn increases the oxygen demand of the heart. When there is increased work or stress on the heart, sometimes that vigorous activity can lead to a plaque rupture if there is hardening of the arteries. The cold weather constricts the small arteries and your heart must work harder to pump blood through the narrowed arteries, therefore reducing the supply of oxygen-containing blood to your heart muscle.
A classic example is associated with the first heavy snowfall of the year. Individuals who shovel may be unaccustomed to this exertion. Some may experience attacks of chest pain called “angina” or may collapse with a heart attack because of this exertion, combined with the increased heart rate and blood pressure from the cold.
The Cardiac Services department at Eastern Niagara Hospital recommends the following:
• Dress warmly and stay dry: To protect health and safety in the cold,
consistently wear a hat or other head covering, use a scarf or knit mask to cover face and mouth, wear sleeves that are snug at the wrist, wear mittens (they’re warmer than gloves), wear several layers of loose-fitting clothing, wear water-resistant coat and shoes, stay dry — wet clothing chills the body rapidly.
