In the summer, farmers are go, go, go. But before you walk out the door, put on that sunscreen and the wide-brimmed hat. Skin cancer is no joke with one in five Americans experiencing a form of skin cancer. And if you think taking a break in the shade is time wasted... imagine the time spent at the hospital if you do develop cancer or have a heat stroke. Monitor your body -- strange moles, blurred vision, etc. -- these could be signs of a problem. Melissa Ploeckelman at the National Farm Medicine Center recommends drinking eight, 8oz cups of water every hour when working in the sun -- if you sip it slowly, you won't have to take constant bathroom breaks.
