While the National Weather Service has not yet issued a heat advisory for Middlesex County, Melrose may experience its first heat wave — three days or more of 90-degree weather — of the season this week. Beginning on Tuesday and continuing into Friday, temperatures in our area could consistently reach 90 degrees or higher.

The City’s Emergency Management and Health & Human Services departments have collaborated with the Mayor’s Office to share tips and community resources to help the community cope with extreme heat.

Here is some advice for what to do — and what not to do — during periods of extreme heat and humidity, from mass.gov: 

-Never leave children or pets alone in a closed vehicle. Even with the windows cracked open, interior temperatures can rise almost 20°F within 10 minutes. 

-Slow down and avoid strenuous activity. 

-Wear lightweight, loose-fitting, light-colored clothing. Light colors reflect heat and sunlight and help maintain normal body temperature. 

-Drink plenty of water — even if you are not thirsty. Avoid alcoholic beverages and liquids high in sugar or caffeine. If your doctor generally limits the amount of fluid you drink, ask how much you should drink during hot weather. 

-Eat well-balanced, light, regular meals. 

-Stay indoors as much as possible and limit exposure to the sun.  

-Do not leave pets outside for extended periods of time. 

-If you must be outdoors, limit your outdoor activity to the morning and evening hours.

-Try to rest often in shady areas so your body temperature will have a chance to recover.  

-Use sunscreen with a high SPF and wear a wide-brimmed hat. 

-If you do not have air conditioning, stay on your lowest floor, out of the sun. Use fans to stay cool and avoid using your stove and oven. 

-Know the symptoms of and watch out for heat-related illnesses. Call 9-1-1 to report emergencies. 

-Be a good neighbor. Check on family, friends, and neighbors, especially the elderly, those who live alone, those with medical conditions, those who may need additional assistance, and those who may not have air conditioning.
