Oklahoma gardeners are feeling the heat now that the temperatures are nearing the triple-digit mark. Couple soaring temperatures with high humidity, and gardeners may need to look for respite in the shade.
As the summer heat intensifies, gardeners must be aware of the dangers of heat exhaustion and heat stroke. Both can be dangerous and require medical attention, said David Hillock, Oklahoma State University Extension consumer horticulturist.
"Gardeners put in much work to make their gardens look so good, and as summer peaks, the weather will continue to stay warm," he said. "As gardeners spend more time with garden upkeep, there are things they can do to help protect themselves from the sun."
Getting gardening work done early in the day or later in the evening will help gardeners avoid excessive exposure to the sun. Wearing a wide-brimmed hat helps gardeners cut down on direct sun exposure to the face and neck.
Also, wearing light-colored, light-weight, loose-fitting clothing will help reduce sun exposure.
"It may sound counterproductive, but long pants and sleeves will keep the sun from hitting your arms and legs directly," Hillock said. "Gardeners will feel cooler than they would in a T-shirt and shorts. Add a pair of UV-blocking sunglasses to protect your eyes."
Dr. Stacy Chronister, an internal medicine specialist at the OSU Center for Health Sciences, said gardeners are often exposed to extreme heat and humidity.
"When we're in the heat, our bodies lose much more water quickly. As we sweat, the heat dries the liquid off our bodies and helps us cool off," she said. "But, the humidity creates a feeling of stickiness, and our bodies don't dry off. The longer that water stays on us, the harder our body has to work to cool down."
Heat exhaustion and heat stroke are common among those who work outdoors. Stomach cramps, headache or lightheadedness are symptoms of heat exhaustion. Heat stroke symptoms include throbbing headache, nausea, vomiting, racing heartbeat and elevated body temperature. Seek medical attention immediately, especially if the person loses consciousness.
"If you know you're going to be outside, start drinking water two or more hours in advance - ideally about 4 cups," Chronister said. "Consume 1 cup of water for every 15 to 20 minutes you're outside. Staying hydrated is critical when working in the heat and humidity."
She said the body will lose electrolytes after about an hour in the sun. At that point, it's a good idea to consume electrolyte-replacement drinks.
In addition, Chronister advises gardeners to wear sunscreen with at least a 30 SPF. Be sure to apply sunscreen to areas often overlooked, such as the tops of ears or the scalp.
Hillock stressed the importance of taking frequent breaks if gardening and landscaping tasks take several hours.
"There are many benefits of gardening, and it's important for gardeners to protect themselves from the summer heat," he said.
