Rising temperatures increased the strain on hearts, according to cardiologist Dr. Carlos Albrecht. While hot weather causes discomfort, it can be particularly dangerous for individuals with high blood pressure or heart conditions, as even healthy hearts may struggle when the body works overtime to stay cool.
Dr. Carlos Albrecht, an Intermountain Health cardiologist at St. James Hospital in Butte, Montana, provided several tips for summer safety.
Maintaining hydration was identified as a priority because the heart must work harder during dehydration. Drinking water helps blood circulate more easily and allows the body to cool via sweat, whereas excessive caffeine and alcohol can increase fluid loss. To avoid heat stress, it was recommended to avoid the midday sun between 10 a.m. and 4 p.m., planning outdoor activities for the early morning or late evening instead.
Clothing choices also played a role in temperature regulation. Using loose-fitting, light-colored, and breathable fabrics like cotton or moisture-wicking athletic wear helped the body cool itself. Additionally, wearing wide-brimmed hats and sunglasses helped reduce sun exposure.
The importance of monitoring physical limits and medications was emphasized. Overexertion in hot weather increased the risk of heat exhaustion or heart attack. If symptoms such as dizziness, fatigue, or shortness of breath occurred, it was advised to stop activity, rest in a cool area, and drink water.
Certain medications, including beta-blockers, diuretics, and specific blood pressure pills, could increase fluid loss or sensitivity to heat. Individuals were encouraged to consult doctors or pharmacists regarding how their medications might affect heat tolerance.
Finally, recognizing the signs of heat stroke was critical, as it is a medical emergency. Symptoms requiring an immediate 911 call included a body temperature over 103 degrees Fahrenheit, rapid pulse, confusion, dizziness, fainting, or hot, dry skin and profuse sweating.
