Weather Related Risks • Risks associated with both hot and cold weather • Weather can also play a role in safety as well…slippery roads, lightning • If weather is too extreme stay inside.
Hot-Weather Risks • Dehydration- excessive loss of water • May cause dizziness, nausea, confusion • Overexertion- overworking the body • Heat exhaustion-overheating of the body • May result in cold skin, symptoms of shock, dizziness, headache • If any of these symptoms occur go to a cool place and lie down with feet elevated and sip water, if vomiting occurs, get help
Hot-Weather Risks (cont) • Heat Cramps- muscle spasm that results from loss of large amounts of salt and water through sweat • Muscle tightens and is painful! • Heat Stroke- body loses ability to rid itself of excessive heat • Sudden increase in body temp, life-threatening • Symptoms- difficulty breathing, collapses, • Immediately call 9-1-1
