Holiday Tips for Supporting Elderly Loved Ones at Home
While the holidays are synonymous with togetherness, many elderly individuals experience increased isolation and loneliness during this time. Physical limitations,…
According to the Centers for Disease Control, we can expect high temperatures to kill nearly 700 people each year in this country alone, most of them over 70 years of age. The vast majority will not die of heat stroke, heat exhaustion, or dehydration. They will die of heart-related problems, including heart attacks and heart failure.
The reason, says Penn State physiologist Larry Kenney, is that we cool ourselves largely by pumping more blood to the skin, where the heat it carries can be lost to the environment. During hot weather, the increase in blood flow to the skin is huge, up to 20 times as much as in cooler weather. Even at rest, if we’re very hot, we may be pumping nearly two gallons of blood to our skin every minute.
Older adults, the very young, and people with mental illness and chronic diseases are at highest risk. Heat has no boundaries; even young and healthy people are often affected if taking part in strenuous physical activities during hot weather.
Normal aging brings about changes that can affect how some older adults sense and react to warm weather, meaning that they might not get the hydration their bodies need, said an expert at the Huffington Center on Aging at Baylor College of Medicine.
“Thermoregulation, or the body’s ability to maintain a steady temperature, is affected as we age and can lead to hyperthermia, or overheating of the body, in older adults,” said Dr. Robert Roush, associate professor of medicine – geriatrics at BCM.
Changes in the body’s ability to cope with hot weather can result in dehydration in older adults because they lose their sense of thirst or do not sweat as much. Due to thinning of the skin, they also overdress because they feel cold, said Roush.
Hydrate, hydrate, hydrate!
Water is one of the most important things we can give ourselves to cool our bodies.
So how much water do you need to stay safe? It is recommended we drink six to eight glasses of water a day – but this increases dramatically in hot weather.
During heavy exercise in a hot environment, drink two to four glasses of cool fluids each hour.
The Arizona Department of Health Services – experts in treating people in extreme heat waves – warns people outdoors in dangerous heat can need one to two liters per hour.
Drink for your health!
