It seems that the heat is on, folks.

The University of Maine’s Climate Analyzer reported this week that worldwide temperatures on several recent days were the hottest on record.

Not every agency agrees with that. The National Oceanic and Atmospheric Administration, for instance, distanced itself from the declaration that this has been the hottest week since record-keeping began 44 years ago.

I am certainly not qualified to say whether the climate analyzer, which uses satellite data and computer simulations to measure conditions, is accurate or whether its conclusions are meaningful. But I can tell you that it has been hot and humid here in Eastern Ohio.

Early last week, as our nation celebrated the anniversary of its independence, conditions were so muggy they were exhausting. Even minimal exertion could leave one dripping in sweat.

Such heat and humidity can make it difficult to complete outdoor tasks or to enjoy picnics and holiday celebrations.

So, what can we do to protect ourselves during these dog days of summer?

According to Ready.gov, there are several steps we can take to guard against heat-related illness.

First, be prepared for extreme heat. If you don’t have air conditioning in your home, identify places where you and your family can go to get cool. These might include shelters or destination as common as a library or shopping mall.

To help keep your home cool, cover windows with drapes or shades to block out the blazing sun. Use weather strips to insulate doors and windows against the heat outside.

You can also use window reflectors, attic ventilator fans or window air conditioning units to help cool your home. You can also take cool baths or showers on hot days.

Outside of your house or apartment, make sure to keep yourself and others safe. Never leave a pet or a person in a hot car on a sweltering day.

Wear loose, light-colored clothing that is lightweight and comfortable.

If you must be outside, find shady spots where you can spend your time. Wear a wide-brimmed hat to protect your face.

Drink plenty of fluids — not alcohol, which dehydrates the body.

Avoid strenuous, high-energy activities that can cause your body to heat up. This is especially important at mid-day, when temperatures will reach their high points.

You should also learn the signs of heat-related illnesses. Signs of heat stroke include: extremely high body temperature, reaching 103 degrees Fahrenheit or more; a rapid, strong pulse; dizziness, confusion or unconsciousness.

Heat cramps can result in muscle pains or spasms, especially in the stomach, arms or legs.

Heat exhaustion can lead to heavy sweating, paleness, muscle cramps, tiredness, fast or weak pulse, dizziness, headache, fainting, nausea and even vomiting.

If you experience mild symptoms of these medical conditions, move to a cool location, remove excess clothing and sip on water or a sports drink. If your symptoms worsen or are serious, get medical attention immediately.

In an effort to head off any of these problems, keep a close eye on children and pets, particularly when they are playing outdoors. Older adults or those with chronic health conditions can also be more vulnerable to the heat.

And, be a good neighbor and remember to check on friends, relatives and neighbors.
