It’s That Time of Year Again

Summer Means High Temperatures and High Humidity–even in Minnesota

We know it’s hot when it’s in the 90’s, but when the dew point is higher than 57, the effect of the temperature is greater than the numbers.  For instance, on June 23 in the Twin Cities, we were told to expect temperatures of 96 0r 97 degrees.  With the dew point around 70, it felt like around 108 degrees–a very dangerous temperature that resulted in heat warnings for Hennepin and Ramsey counties (Minneapolis and St. Paul and suburbs.)

As we age, we are less able to respond to heat and cold.  During hot and humid weather, a buildup in body heat can cause heat stroke or heat exhaustion.  This is especially true for people with heart and circulatory disease, stroke or diabetes.

Heat Stroke is a medical emergency requiring immediate attention and treatment by a doctor.  Among the symptoms are:  faintness, dizziness, headache, nausea, loss of consciousness, body temperature of 104 degrees F. or higher, rapid pulse, and flushed skin.

Heat Exhaustion takes longer to develop than other heat-related illnesses.  It results from a loss of body water and salt.  Symptoms include:  weakness, heavy sweating, nausea, and giddiness.  Heat exhaustion is treated by resting in bed away from the heat and drinking cool liquids.

Protective Measures include remaining indoors in an air-conditioned room.  If the home is not air-conditioned, you might take your loved one to a cool public place (library, movie theater or store) during the hottest hours.

Other ways to cool off include taking cool baths or showers, placing ice bags or wet towels on the body and using electric fans (being careful to avoid an electrical shock.)

Remember that persons with memory loss and the other cognitive impairments that go along with dementias like Alzheimer’s disease often lack good judgement.  You may need to make sure that those you care for wear appropriate hat, sunglasses and sun screen.
