Without stating the obvious:
Summer heat can be dangerous – even deadly – if you don’t take the proper precautions. 
Everyone should follow these basic heat safety tips in order to avoid the dangers of heat exposure. Keep these suggestions in mind:

Dress lightly, and when sleeping, use lightweight, breathable covers.

Drink plenty of water and other fluids. According to the Heat

It’s important to drink at least a gallon of liquid per day, preferably water. Those who are overweight and in humid conditions needing even more.

Avoid drinking alcohol and beverages that are carbonated or contain caffeine when temperatures are high, as they can lead to dehydration.

Keep blinds and curtains closed from morning until the late afternoon to block extra direct heat from sunlight.

Move your exercise routine to early morning or later in the evening.

Never ever leave a person or a pet in the car in hot conditions while you run to do a quick errand. People and animals can succumb to heat exposure and death very quickly in a hot car. Cars can become overheated quickly and when overheated become like ovens.

It’s never safe.
Properly supervise children during outdoor play, water and near pools, being sure to monitor them constantly.

Seek medical care right away if you become nauseous, start vomiting or experience cramps.

Stay on the lowest level of your home.

Use a fan.

Don’t place the fan directly in front of a window because it may push hot air in. Try placing the fan so that it blows in the room and out the window instead.

Use small appliances like slow cookers and tabletop grills rather than your traditional oven or stove to keep kitchen heat to a minimum.

Verify that seat belts and car seat restraints are not too hot before buckling yourself or anyone else into a car.
