 It was also monitoring the situation and in contact with local EMS agencies in turn. State officials meant to discuss the rising temperatures, reminiscent of the severe California heat wave of 2006, when a two-week stretch of well above average temperatures cost more than 130 people their lives and more than 25,000 cattle were lost due to heat-related illnesses. Here are the things you need to keep in mind to prevent a heat-related illness. First, keep plenty of drinkable water on hand at all times and keep yourself hydrated. Avoid strenuous activities during the peak heat of the day, which is in the mid to late afternoon hours. Try to do your outdoor work during the morning hours when it's coolest. And of course, never leave a child or a pet unattended in a car. This rule applies year-round.
