FORT WORTH (CBSDFW.COM) – When it comes to heat related calls, the summer of 2013 has been a quiet one compared to 2012.

Last year, MedStar responded to 344 heat-related calls from May to September.

With another two months to go, MedStar has responded to 200 fewer calls so far in 2013.

For the most part, temperatures have been cooler in 2013, which has led to fewer-heat related emergencies.

But as August begins, that could change.  On the first day of the month, MedStar responded to five heat related calls.

“Each day that its above 100, it makes it worse for all the people out there,” says MedStar paramedic Marshall Sharp.

At the Dallas Mayor’s Back To School Fair, Dallas Fire and Rescue treated eight people for heat-related problems.

EMS crews warn not to take the heat for granted and remind everyone to stay hydrated before going outside.

“It takes time for the fluids to get into your body where they need to be to effectively hydrate,” says Jason Evans from Dallas Fire and Rescue.

MedStar provided the following reminders for heat related emergencies:

Never Leave Children, Disabled Adults or Pets in Parked Vehicles
Each year, dozens of children and untold numbers of pets left in parked vehicles die from hyperthermia. Hyperthermia is an acute condition that occurs when the body absorbs more heat than it can handle. Hyperthermia can occur even on a mild day. Studies have shown that the temperature inside a parked vehicle can rapidly rise to a dangerous level for children, pets and even adults.  Leaving the windows slightly open does not significantly decrease the heating rate. The effects can be more severe on children because their bodies warm at a faster rate than adults.
