With weekend temperatures expected to reach the upper 90s, residents are advised to take precautions when going outside. Washington County Public Health Administrator Edie Nebel says high temperatures combined with low hydration can result in some serious health problems. Nebel says the two most frequent problems encountered are heat exhaustion and heat stroke. She says exhaustion is characterized by a rapid pulse and stomach or headaches, while stroke can even result in death if ignored. Nebel says its important to get inside and cool off and drink liquids if you begin to feel too hot.
