Today’s older adults are more active than ever before, and warm summer months are the perfect time to garden, swim, or have a picnic. However, physical changes that occur as people age can make summer heat more dangerous. Older adults may be at a higher risk for heat stroke and heat exhaustion because they are less likely to realize when they are too hot, even when temperatures outside are high. They are also less likely to realize when they are thirsty, and may have trouble cooling down as quickly as they did when they were younger. If spending extended time outdoors, older adults should make sure to drink plenty of cool water, spend time in the shade, and alternate time spent outside with time spent inside with air conditioning.
