Triple digit heat sizzles Southland

A late summer heat wave has hit the southland and there's no relief in sight.

Triple digit temperatures sizzled much of the San Fernando Valley on Thursday, dropping to only a balmy 89 degrees in the evening.

Earlier in the day, people were seen at parks in Sherman Oaks and Van Nuys in the early morning trying to remain active despite the heat.

"That's why I come at 4:30 a.m. because it just gets too warm," said Van Nuys resident Jean Henry. "Particularly when it was muggy like yesterday, the air was so heavy."

Health experts always advise playing sports indoors or early in the morning before the outside temperatures peak.

The scorching sun and sweltering heat can pose a danger to anyone who is out in it. In these conditions, the body even at rest can lose a quart of fluid an hour. For every degree that a persons' core temperature rises, the heart goes 15 beats faster per minute and that can cause serious cardiac stress.

The first warning sign is when you stop sweating in this extreme heat. The others are headaches, dizziness and nausea.

Pets also need extra care; make sure they have access to shade and are hydrated throughout the day.
