It’s prognosis is far better, unless circulatory failure is prolonged. Treatment is aimed at restoring normal blood volumes and improving brain perfusion, thus the person should be placed flat or with their head slightly down. As soon as the person starts responding, a small amount of sugar water should be given. Heat exhaustion should also be treated with fluids and rest. Left untreated, it can progress to heat stroke, which can be deadly.  In heatstroke or sunstroke, an abrupt onset is sometimes preceded by headache, dizziness, and fatigue. Sweating is usually, but not always, decreased and the skin is hot, flushed and dry (usually). The pulse rate increases rapidly and may reach 160; respirations usually increase, but the blood pressure is seldom affected. Disorientation may briefly precede unconsciousness or convulsions. The body temperature can rapidly climb to 106 degrees or higher and the person feels as if he or she burning up. Circulatory collapse may precede death. After hours of extremely high fever, survivors are likely to have permanent brain damage. Treatment measures must be instituted immediately. If distant from a hospital, the person should be wrapped in wet clothing or fabric, or immersed in a lake or stream. The temperature should be taken every ten minutes, not allowing it to become too low. The person should be taken to a hospital as soon as possible after the emergency methods have been initiated. No fluids by mouth should be attempted. Bed rest is desirable for a few days after severe heatstroke, and body temperature fluctuations may be expected for weeks.  Protect your health during hot weather. Take a look at the following tips to prevent heat illness: Drink plenty of fluids. Regardless of your activity level, increase the amount of fluids you drink. Replace salt and minerals. Heavy sweating removes salt and beverages you have consumed from the body. Wear appropriate clothing and sunscreen. Choose lightweight, light colored, loose fitting clothing. In the hot sun, use sunscreen and don a wide-brimmed hat to provide shade and keep the head cool. Pace yourself. If you are unaccustomed to working or exercising in a hot environment, start slowly and pick up the pace gradually. Your body needs time to acclimate. Stay cool indoors. Air-conditioning is one of the best ways to stay cool. If you do not have an air conditioner or evaporative cooling unit, head for a shopping mall or public library for a few hours, or sit in front of a fan (with a wet towel draped around you, if necessary). Bathing is an effective way to cool off. Schedule outdoor activities carefully. Plan outdoor activities for the early morning or in the evening. While outdoors, rest frequently in a shady area. Use a buddy system. When working in the heat, monitor the condition of your co-workers and have someone do the same for you. Heat-induced illness can cause a person to become confused or to lose consciousness. Although Florida has a mild winter, the summers are extremely hot. With the temperatures already increasing, we are heading into the warmest time or the year. Enjoy what Florida has to offer, safely!
