Some commonsense tips for staying safe in extreme heat

As temperatures begin to warm up throughout the state, California Department of Public Health (CDPH) Director Dr. Karen Smith advises California residents to prepare themselves for what could be a very hot, dry summer.

“Because this hot spell has come on rather suddenly, many people may be caught off guard by the warm up,” Smith said. “It is important that all Californians take precautions to prevent heat-related illness and stay hydrated.”

In areas where air quality is impacted, people with heart disease, asthma or other respiratory diseases should minimize outdoor activities. Summer schools and programs with children who have sensitive conditions, including heart disease, asthma and other respiratory diseases should not participate in outdoor physical activity and should stay indoors as much as possible.

Extreme heat poses a substantial health risk, especially in vulnerable populations including young children, the elderly, people with chronic diseases, pregnant women, people with disabilities, and people who are socially isolated. Heat-related illnesses include cramps, heat exhaustion and, most seriously, heat stroke and death. Warning signs of heat-related illnesses vary, but may include heavy sweating, muscle cramps, weakness, headache, nausea or vomiting, paleness, tiredness or dizziness.

Those lacking air conditioning should go to a cooling center, library, or public place such as a shopping mall to cool off for a few hours each day. Mountain Area cooling centers are:

* Coarsegold Community Center, 35540 Highway 41, Coarsegold, (559) 683-7953, open Monday - Friday, 10 a.m. - 1 p.m.

* Yosemite Lakes Park Clubhouse, 30250 Yosemite Springs Parkway, Coarsegold, (559) 658-7466, open daily 8 a.m. - 8 p.m., water available Monday - Friday; clubhouse office hours, 8 a.m. - 5 p.m.

* Sierra Senior Center, 49111 Cinder Lane, Oakhurst, (559) 658-2200, open Monday - Friday, 9 a.m. – 2 p.m.

* Grace Community Church, 56442 Road 200, North Fork, (559) 877-2346, open Monday - Friday, 10 a.m. - 1 p.m.

Here are some tips to stay safe in extreme heat:

* Avoid physical exertion/exercise outdoors during the hottest parts of the day to avoid overheating. Reduce exposure to the sun from 10 a.m. to 4 p.m. when UVrays are strongest, and keep physical activities to a minimum during that time. When working outside, drink plenty of water or juice even if you are not thirsty ... and drink more than you think you need. Your body needs water for many crucial functions, and dehydration can lead to serious health effects. Also, take rest breaks in the shade.

* Check on elderly who live alone every 24 hours; many may be on medications which increase likelihood of dehydration.

* Don’t rely on electric fans during a heat wave, When the temperature is in the 90s or above, a fan will not prevent heat-related illness. To prevent overheating, use cool compresses, misting, showers and baths. Get medical attention if you experience a rapid, strong pulse, feel delirious, or have a body temperature above 102 degrees.

* Never, EVER leave infants, children, frail elderly, or pets unattended in a parked car, even for a moment – it can take as little as 10 minutes for the temperature inside a car to rise to dangerous, life-threatening levels.

* Wear a wide-brimmed hat to cover the face and neck, and wear loose-fitting clothing to keep cool and to protect your skin from the sun and mosquitoes.

* Wear sunglasses that provide 100 percent UVA and UVB protection. Chronic exposure to the sun can cause cataracts, which left untreated, can lead to blindness.

* Liberally apply sunscreen (at least SPF 15) 15 minutes before venturing outdoors and re-apply at least every two hours – sunscreen may reduce the risk of skin cancer, the number one cancer affecting Californians. Sunscreen may also prevent premature aging.
