Greetings, as a survivor of a heart attack and six-bypass open heart surgery, I personally am health cautious about being in temperatures below 70 degrees and above 80 degrees F. I also mind my physical activities when the humidity is not favorable.
Advice given in an article excerpt “Extreme Weather and Your Heart: What You Need to Know When It Gets Really HOT!” by SCAI SecondsCount. http://secondscount.org/heart-condition-centers/info-detail-2/extreme-weather-your-heart-what-you-need-to-know-w#.YKv-caEpDIU
“When the temperature reaches 70 degrees Fahrenheit (21 degrees Celsius) and the humidity is 70 percent or higher, your heart has to begin to work harder just to cool your body. When the outdoor temperature climbs into the 80s (Fahrenheit) or high 20s (Celsius) or beyond and there is high humidity, the risk to your health also rises. If you have heart disease, it is especially critical that you avoid exercising when the temperature and the humidity are both high. Consider delaying any intense exercise until the temperature has dropped and the humidity has reduced, or consider doing your doctor-approved exercise where the weather won’t be a problem, such as in air conditioning or in a swimming pool. “
