Heat Stroke is a medical emergency which occurs when the body's internal mechanism fails to regulate core temperature. Sweating stops. The body can no longer rid itself of excess heat. Signs include: a distinct absence of sweating; hot red or flushed dry skin; rapid pulse; difficulty breathing; constricted pupils severe dizzines, headache, nausea, vomiting, or confusion; bizarre behavior; and high blood pressure. Advance symptoms may be seizure or convulsions, collapse, loss of consciousness, and a core temperature of 106 degrees Farenheit or higher.
Heat Syncope (fainting) can result when the brain does not receive enough oxygen due to blood poolng in the extremities. This reaction does not affect the body's heat balance. Acclimatizing and avoiding standing motionless for long periods can reduce the likelihood of fainting.
Heat Exhaustion results when fluid or salt is lost through sweating without being replaced. A person with heat exhaustion may experience headache, heavy seating, intense thirst, dizzines, fatigue, loss of coordination, nausea, impaired judgement, loss of appetite, hyperventilation, tingling in hands or feet, anxiety, cool moist skin, or a weak, rapid pulse. The body still produces sweat and the body temperature is normal or slightly higher than normal.
Heat Cramps are painful muscle spasms, usually affecting the arms, legs, or stmach. Heavy sweating can cause heat cramps, especially when drinking water to replace fluids. Remember to avoid liquids that contain salt or potassium. Cramps can occur during work, but they typically take place after the work shift has ended. Eating bananas and taking sufficient salt - without overding it - can help prevent heat cramps.
Heat rash can break out where sweat is not effectively removed from the skin through evaporation. A heat rash that is extensive or complicated by an infection can inhibit sleep, impede performance, or even result in temporary total disability. Heat rashes can usually be prevented by making sure the skin is allowed to dry during rest breaks.
