Deaths from heart disease rise rapidly during holiday season. Heed these tips from The American Heart Association to stay healthy this winter.
The American Heart Association's Operation Winter Weather Warnings launched today with an educational campaign targeted to individuals with existing heart disease or stroke, and those who may be at high risk. This includes people with a strong family history, high blood pressure, high cholesterol, smokers, those who are overweight, and the sedentary. For these individuals, the stresses of the season may pose extra concern, and the association is urging individuals to exercise due caution to avoid sudden cardiac death.
Deaths from coronary artery disease tend to rise rapidly right after Thanksgiving, continuing through Christmas, and peaking around New Year's Day. Several factors may influence this unfortunate trend, from an increase in respiratory infections during the winter, to increased workload on the heart from activities such as shoveling heavy snow.
The American Heart Association recommends the following tips to help respond to and prevent sudden cardiac arrest:
Avoid sudden cold weather exertion
Snowstorms present particular challenges for everyone, primarily because getting rid of the snow usually means sudden exertion in cold weather. Snow shoveling can be healthy exercise, but not if you are normally sedentary, are in poor physical condition, or have risk factors that make snow shoveling inadvisable for your health. Everyone who must be outdoors in cold weather should avoid sudden exertion, like lifting a heavy shovel full of snow. Even walking through heavy, wet snow or snowdrifts can strain a person's heart.
Recognize the symptoms of hypothermia
Hypothermia occurs when your body can't produce enough energy to keep the internal body temperature warm enough, causing it to fall below normal. It can kill you. Heart failure causes most deaths in hypothermia. Symptoms include lack of coordination, mental confusion, slowed reactions, shivering, and sleepiness.
Children, the elderly, and those with heart disease are at special risk. As people age, their ability to maintain a normal internal body temperature often decreases. Because elderly people seem to be relatively insensitive to moderately cold conditions, they can suffer hypothermia without knowing they're in danger.
People with coronary heart disease often suffer chest pain or discomfort called angina pectoris when they're in cold weather. In addition to cold temperatures, high winds, snow, and rain also can steal body heat. Wind is especially dangerous, because it removes the layer of heated air from around your body. Similarly, dampness causes the body to lose heat faster than it would at the same temperature in drier conditions.
To keep warm, wear layers of clothing. This traps air between layers, forming a protective insulation. Also, wear a hat or headscarf. Much of your body's heat can be lost through your head, and ears are especially prone to frostbite. Keep your hands and feet warm, too, as they tend to lose heat rapidly.
Avoid alcohol before heading outdoors
Alcohol gives an initial feeling of warmth, but this is caused by expanding blood vessels in the skin. Heat is then drawn away from the body's vital organs. Alcohol consumption and physical activity in harsh winter weather conditions can increase the likelihood of hypothermia.
Learn CPR and/or Hands-Only CPR
About 80 percent of all out-of-hospital cardiac arrests occur in private residential settings, so being trained to perform cardiopulmonary resuscitation (CPR) can mean the difference between life and death for a loved one. Effective bystander CPR, provided immediately after cardiac arrest, can double a victim's chance of survival.
