Extreme Heat Events Jeopardize Cardiovascular Health, Say Experts.

Factory worker man working in hot weather and he look tired from work.Due to concerns about climate change, the Canadian Journal of Cardiology has examined how extreme heat can affect heart health. Due to global warming, a greater frequency and intensity of extreme heat events have been predicted to take place across the globe.

Extreme heat has been associated with a greater risk of adverse cardiovascular incidents, particularly for adults with pre-existing cardiovascular diseases. It has previously been shown to pose a threat to health by increasing the risk of morbidity and mortality.


Researchers have referred to the 70,000 deaths attributed to the European heatwave in 2003 and 55,000 deaths attributed to the 2010 Russian heatwave. Risk factors that were noted for heat-related hospitalization included age, chronic illness, medications, social isolation, and lack of access to air conditioning. Poor heart health is often identified as a risk factor among chronic conditions from heat-related hospitalization and death.

The authors of the study noted a consistent association between extreme heat and a greater risk of adverse cardiovascular health outcomes. Through examinations of systematic reviews and meta-analyses, they considered the effect of extreme heat and adverse cardiovascular outcomes. They concluded the heat waves significantly increase the risk of death from ischemic heart disease, heart failure, and stroke.

Events Occur Without Heatstroke

Dr. Gagnon, lead author of the study, explained, “Although the effects of extreme heat on adverse cardiovascular events have been explained in the context of heatstroke, many events occur without heatstroke, and the mechanisms of these events in the absence of heatstroke remained unclear. It is likely that heat exposure increases myocardial oxygen needs.”

After the conclusion of the study, the authors proposed some healthy heart tips and heatwave safety precautions. These precautions include paying attention to early heat warnings, identifying the signs of heat stress, ensuring people drink adequate amounts of cold fluid, and seeking an air-conditioned environment.

Author Bio

Sarah began her interest in nutritional healing at an early age. After going through health problems and becoming frustrated with the conventional ways doctors wanted to treat her illness (which were not working), she took it upon herself to find alternative treatments. This led her to revolutionize her own diet to help her get healthier and tackle her health problems. She began treating her illness by living a more balanced lifestyle through healthy food choices, exercise and other alternative medicine such as meditation. This total positive lifestyle change led her to earn a diploma in Nutritional Therapy from Health Sciences Academy in London, England. Today, Sarah enjoys helping others by teaching healthy lifestyle changes through her personal consultations and with her regular contributions to the Doctors Health Press. Also, passionate about following her dreams in life, Sarah moved to France and lived in Paris for over 5 years where she earned a certification in beadwork and embroidery from Lesage (an atelier owned by Chanel). She then went on to be a familiar face sitting front row and reporting from Paris Fashion Week. Sarah continues to practice some of the cultural ways of life she learned while in Europe. They enjoy their food, and take the time to relax and enjoy many of life’s little moments. These are life lessons she is glad to have brought back home with her.
