With a heat wave in full swing, the Middlesex-London Health Unit is asking London residents to check on family, friends and neighbours and help them get relief from the heat.

Humidex values were in the mid-40s on Wednesday, and the health unit says it’s the hottest, most humid and stifling weather in the region in seven years.

A heat alert remains in effect for a third day, and officials are asking that people keep an eye out for anyone in distress.

Middlesex EMS have responded to numerous calls likely related to the heat since Monday including:

  • 15 for shortness of breath
  • 13 for seizures
  • 12 for chest pains
  • 60 for feeling generally unwell

EMS recommends calling 911 when symptoms of heat illness can’t be easily dealt with by moving to a cooler place or taking a cool shower or bath.

Jay Loosley, superintendant of education with Middlesex EMS said in a statement, symptoms to watch out for include “nausea, vomiting, disorientation, fainting and rapid breathing.”

Chris Mackie, medical officer of health for the Middlesex-London Health Unit, said in a statement “This is not just normal summer heat. This is when vulnerable people can start to die…That’s why it’s important to check in on family members, loved ones, neighbours and seniors to see how they’re doing and assist them to get to places they can cool off.”
