Whether your job requires outside work or you're just trying to get your lawn chores done on the weekend, the CDC recommends scheduling the most strenuous labor for the early morning and late afternoon, when the sun's rays are less powerful. But during a heat wave, even those times of day can be sweltering. Always wear a sun-protective hat and broad-spectrum sunblock to avoid burning. For further protection, wear dark colors and tight-knit fabrics, which block more of the sun's harmful UVA and UVB rays. And don't forget that your eyes are sun-sensitive: your corneas can get sunburned in a painful, though temporary, condition called photokeratitis, which can lead to vision loss. And long-term sun exposure can contribute to cataract risk. As always, make sure you're drinking enough fluids, even before you feel thirsty. Dehydration comes quickly in high temperatures, and physical exertion brings it on even more quickly — whether you're laying bricks or simply pushing the lawn mower.
