Global Warming May Threaten Heart Health

Global Warming May Threaten Heart Health


As temperatures rise due to global warming, scientists are worried about how extreme heat may impact heart health. Research published in the Journal of Applied Physiology warns that air temperatures as low as 93° F may lead to a steady increase in heart rate under humid conditions. This increase, referred to as cardiovascular heart strain, can occur even before a person’s internal temperature starts to rise.

The study involved healthy participants engaging in light physical activity inside an environmental chamber. As the chamber got hotter, participants’ heart rates increased and then plateaued. However, when the chamber continued to heat up, heart rates began to rise again and continued to rise even after the experiment. This rapidly increased heart rate indicates cardiovascular strain.

A related study published in Physiological Reports reported that even at rest, heat can affect the heart. Researchers found that at 50 percent humidity, the heart rate of participants at rest was, on average, 64 percent higher at 122° F than at 82° F. These findings are concerning, as extreme heat events are becoming more common around the world and could be lethal for vulnerable and older populations.

5 Top Tips to Finding Your Next Doctor

1 Keep an Open Mind! Healthcare has come a long way. Today, you have access to practitioners that branch outside of traditional medicine and aim to identify the root causes of conditions while using alternative treatments that may help you get the relief you need. Just because it’s not a pill, doesn’t make it pseudoscience.

2 Build Your Health Care Team. There is no one doctor that can be the be-all-end-all for your health needs. Be sure to have a team of practitioners with different “lenses” and areas of expertise who will treat the root cause and not just the symptom(s).

3   Environment Influences Healing. Health is multi-factorial. Your mental and emotional environment plays a pivotal role in your healing potential. Your doctors and their staff should create an office atmosphere filled with positivity so you can get the most out of your care.

4 Your Story Matters.  Before you begin any treatment, be sure to have a comprehensive consultation to discuss your health concerns. Find practitioners who welcome questions and will take the time to listen and treat you with respect.

5 Report of Findings. When it comes to our health, we often make decisions without understanding the risk versus benefits. Knowledge is an important part of the healing process and is essential to make conscious, informed health decisions. Find practitioners who take the time to explain their exam findings and the recommendations for treatment in ways that make sense to you.
