A level-one heat warning was issued by Environment Canada for parts of central and northern New Brunswick on Wednesday.

“There are three levels of the heat alert response system, so today is a level one alert,” says NB Acting Chief Medical, Dr. Jennifer Russell. “It’s more directed towards people who would have predisposing conditions that would make them more vulnerable to the heat.”

According to Environment Canada, the warning means humidex values could be reaching near 40 by Thursday afternoon. It warns with the rise in humidity, comes an increase of health risks for older adults, young children, people with chronicle illnesses and those who spend long hours outdoors.

After the alert was issued, some starting making adjustments to their day – including a children’s day camp.

“We are doing some water games, and we have a lot of water to keep hydrated,” saysRebecca Larsen, a day camp leader for Odell Park. “Sunscreen and hats, and staying out of direct heat.”

Although level-one heat alerts are typically geared towards children and seniors, Dr. Russell says everyone needs to be aware. She says as the temperatures rise, everyone, no matter what age, should be cautious.

“If you have activities that you can avoid, again on a day like today when we’re on heat level one, and if you’re a healthy person and don’t have any preconceived risks for developing heat illness or heat strokes, still use your common sense,” says Dr. Russell. “Hydrate yourself really well.”

Some events around Fredericton were altered today. The changing of guard at Officers’ Square took place at 11 a.m., but was cancelled in the afternoon.

Construction sites were busy, but the city of Fredericton was warning those working outside in the sun.

“Watch your employees, make sure they stay hydrated,” says Wayne Knorr of Fredericton. “You may need frequent breaks when the heat is really hot, like it is right now. Enjoy some shade if you can.”

Many people have different ways to cool off.

“I drink water to stay cool, stay in the shade, walk only in the morning, and we take our walk always early in the morning,” says resident Bridget Domno.

Taking small steps to ensure summer safety is also important when it comes to pets. Dr. Russell says pet owners should make sure their animals have plenty of water and food, and aren’t left outside for too long.
