Summer Temps & Heart Health: Keeping You Cool as August Heats Up!<\/span><\/h3>\n<\/div><\/section>\n

Tipping into the \u201cdog days of summer\u201d for much of the country means temps are getting hotter \u2013 which can be uncomfortable for everyone. But for people concerned about their heart health, hot, humid days can actually be dangerous.<\/p>\n

Here\u2019s why: If your temperature rises too much, your body works to shed the extra heat in two ways, both of which stress the heart.<\/p>\n

    \n
  1. Radiation<\/strong>: Like water flowing downhill, heat moves from warm areas to cooler ones. When the air around you is cooler than your body, you radiate heat to the air. But this transfer stops when the air temperature approaches body temperature. Radiation requires rerouting blood flow so more of it goes to the skin, which makes the heart beat faster and pump harder. On a hot day, it may circulate two to four times as much blood each minute as it does on a cool day.<\/li>\n
  2. Evaporation<\/strong>: Every molecule of sweat that evaporates from your skin whisks away heat \u2013 but it also strains the cardiovascular system. Sweat pulls much more than heat from the body; it also pulls out sodium, potassium, and other minerals needed for muscle contractions, nerve transmissions and water balance.<\/li>\n<\/ol>\n<\/div>\n<\/div>\n<\/div>\n

    SUMMER PRECAUTIONS<\/strong><\/span><\/h3>\n<\/div><\/section><\/div>

    \u201cIf you\u2019re a heart patient, older than 50 or overweight, you might need to take special precautions in the heat,\u201d said Gerald Fletcher, M.D., professor of medicine at the Mayo Clinic, in Jacksonville, Fla.<\/p>\n

    Here are a few tips from the\u00a0American Heart Association<\/a>\u00a0to help you brave the heat:<\/p>\n<\/div><\/section><\/div>

    Watch the Clock<\/strong><\/h3>\n

    It\u2019s best to avoid the outdoors in the early afternoon (about noon to 3 p.m.) because the sun is usually at its strongest, putting you at higher risk for heat-related illnesses.<\/p>\n<\/div><\/section><\/div>

    Buddy Up<\/h3>\n

    If you can, exercise with a friend, because it\u2019s safer \u2014 and more fun \u2014 to have someone at your side.<\/p>\n<\/div><\/section><\/div>

    Get Off on the Right Foot\u00a0<\/strong><\/h3>\n

    You probably sweat the most in your shoes, so choose well-ventilated shoes and look for socks that repel perspiration. Foot powders and antiperspirants can also help with sweat.<\/p>\n<\/div><\/section><\/div>

    Dress for the Heat\u00a0<\/strong><\/h3>\n

    Wear lightweight, light-colored clothing in breathable fabrics such as cotton, or a synthetic fabric that repels sweat. Add a hat and\/or sunglasses.<\/p>\n<\/div><\/section><\/div>

    Drink Up\u00a0<\/strong><\/h3>\n

    Stay hydrated by drinking a few cups of water before, during and after your exercise. Avoid caffeinated or alcoholic beverages.<\/p>\n<\/div><\/section><\/div>

    Take Regular Breaks<\/strong><\/h3>\n

    Find some shade or a cool place, stop for a few minutes, hydrate and start again.<\/p>\n<\/div><\/section><\/div>

    Implementing just a few preventative measures can help your heart stay healthy all summer long \u2013 even on its hottest days!<\/p>\n<\/div><\/section><\/div>
