LA CROSSE, Wis. -

On extremely hot and humid days like the ones we're experiencing this week, health experts say you need to be constantly drinking water throughout the day, not just when you get thirsty.

If you become dehydrated, it will increase the risk of heat stroke and other heat-related illnesses.

Experts say it's especially important for young children and the elderly to take care of themselves on scorching summer days. That includes staying in cool places and wearing cooler clothing. "Older people tend to bundle up because they always feel cold, because of medications or other chronic health conditions. Small children we tend to bundle them up too because we're so worried about them losing their heat, but we never think about in the summer, oh, maybe they're actually too hot," said Gundersen Health System R.N. Sarah Holthe.

It's the same story for pets too. They need a cool source of water and a place to get away from all of the heat. But you don't have to give up everything with them.

"If you are an avid walker with your dog, you can still do things on days like today, taking shorter walks and goign on walks really early in the morning or later in the evening when it tends to be a little cooler," said Liz Meil with the Coulee Region Humane Society.

If your pet seems to be struggling, panting, or drooling excessively, you might want to take them to the vet to be safe.
