Reducing Summer Heat

 
Trees and built shade can provide a cooling effect by lowering the temperature of the ground surface and the surrounding air.

The urban heat island effect occurs when natural vegetation is replaced by surfaces that absorb heat.  CLICK HERE for more information on the urban heat island effect.
 

In addition, green roofs or using light coloured roofing materials can also decrease heat sinks and temperature in urban areas.

Heat Related Illness
 

In the summer, the combination of heat and humidity puts certain individuals at risk for heat related illnesses such as heat stroke and heat exhaustion.

Heat exhaustion can develop after several days of exposure to high temperatures without adequate fluid replacement.

Heat Stroke occurs when the body is unable to regulate its temperature. The body’s temperature rises rapidly, the sweating mechanism fails and the body is unable to cool itself.

Heat stroke can cause death or permanent disability if emergency treatment is not provided.

Be aware of the signs of heat exhaustion and heat stroke and take action to reduce your risk. Heat the heat and enjoy the summer weather!
