1) Heatstroke – This can sneak up on the active person in the heat of the day. The first signs are thirst and fatigue, which are expected in most cases. But after being in the sun for a while, mere water can’t replace all of the electrolytes lost through sweating and are a vital part of regulating body temperature. That means the symptoms of heat-related issues may progress, and eventually, delirium and hallucinations may set in, leading to organ failure in the most extreme cases. Keep a mix of water and Gatorade on hand. The latter has potassium and sodium, key ingredients that will help rebalance the body’s electrolyte system, much as they did for the Florida Gators football team when the drink was first invented. As for fluid ingestion, try to ingest about a liter bottle of water for each hour spent engaged in vigorous activity while in the sun.
2) Plant Problems - Some plants have natural defense systems that will cause allergic reactions in the skin with just a mere touch. Poison ivy, poison oak and a few other plants will secrete fluids to repel potential threats. Those fluids can cause moderate to severe rashes for anyone foolish enough to handle them. Encountering poison ivy or oak usually means you’re off the trail -- the plants typically are found in the bushes and near shrubs. The best defense against them is to wear proper hiking clothing that covers exposed areas of the body – hiking boots, thick socks, long pants and long-sleeved shirts. Just keep in mind that oils from the plants can get on clothing. If that happens, hikers can touch the oils while taking off clothing. The best treatment for poison ivy or poison oak contact is calamine lotion, which is an anti-itching ointment generally found in most drug stores. Severe cases of poison ivy or poison oak may require steroid treatments from a doctor to clear the skin infections.
