Understanding the Risks of Working in Extreme Heat
Working in extreme heat poses health risks, including dehydration, heat exhaustion, and heatstroke. Such knowledge of the risks of working in extreme heat waves enables people to take the necessary precautions to protect their health.
Heat exhaustion: It results from excessive water and sodium loss from the body due to extreme sweating. Symptoms may include excessive sweating, weakness, lightheadedness, headache, vomiting, and muscle cramps. If not controlled within the shortest possible time, it may escalate into heat stroke.
Heat stroke: Heat stroke is a fatal condition that occurs after prolonged exposure to very high temperatures. It may be characterized by symptoms such as extremely high body temperature, mental disturbance, quickened heart rate, parched skin, and unconsciousness.
Dehydration: Working in intense heat can cause individuals to lose fluids through sweating, leading to dehydration. Symptoms of dehydration may include thirst, dry lips, tiredness, dark-colored urine, and lightheadedness. Severe dehydration can affect physical strength, concentration and overall health.
Reduced physical performance: Very hot conditions can impair an individual's physical capabilities. Workers can feel weak, slow down their movements, have low energy, and be unable to concentrate properly. The result could be lower efficiency and an increased risk of errors.
Increased risk of workplace injuries: When it is too hot, people may suffer from exhaustion, vertigo, and reduced concentration, leading to workplace accidents and injuries. People may slip, trip, or fall, or sustain injuries due to sweaty palms, blurred vision from fogged-up safety goggles, and poor awareness. Outside workers are more prone to work injuries.
Vulnerable groups at higher risk: Some individuals are at increased risk of heat-related disorders. This group may consist of older adults, pregnant women, children, and individuals suffering from pre-existing conditions. The newly hired individuals exposed to very high temperatures and involved in strenuous activities may also belong to such a group.
Importance of preventive measures: Preventive measures play an important role in protecting people against heat illness. Staying hydrated, taking frequent breaks, dressing appropriately, and avoiding the sun will keep you safe. Employers should ensure their employees have a place to relax out of the sun. Employers should also provide shaded rest areas and educate workers about heat-related symptoms.
Heat illness is defined as the onset of symptoms due to exposure to very extreme heat waves that exceed the body's capability to maintain its temperature. Heat illness may include minor problems such as heat cramps or more serious problems, such as heat stroke, especially during summer.
Heat exhaustion
The condition is associated with dehydration from excessive sweating in hot conditions. The signs of heat exhaustion include excessive sweating, dizziness, fatigue, headaches, nausea, and muscle spasm.
Heat stroke
It refers to an urgent health condition resulting from overheating in which the body fails to control its temperature. Signs of heat stroke include very high body temperature, dizziness, confusion, rapid heart rate, lack of sweating, dry skin, and even unconsciousness, all requiring prompt management.
Heat cramps
Cramps caused by heat are very painful muscle spasms that usually happen in one’s legs, arms, or stomach after exercising in very hot conditions. Heat cramps occur when one loses body fluids and electrolytes through sweating.
Heat rash
Heat rash, also called prickly heat, is a common skin problem. The rash occurs when sweat ducts are blocked by sweat, preventing them from excreting excess body fluid in very hot, humid conditions. It appears as small red bumps and causes an itching sensation, especially in skin folds.
Dehydration
Dehydration occurs when the amount of fluid lost exceeds the amount of fluid intake. Common symptoms of dehydration include increased thirst, dry mouth, dark-coloured urine, dizziness, and fatigue.
Sunburn
Sunburn is the skin reaction to excessive exposure to the sun's harmful UV rays. The symptoms include redness, pain, inflammation, and skin peeling. Sunburn also increases the likelihood of developing skin cancer.
Heat syncope(fainting)
Fainting results from an abrupt sensation of lightheadedness or fainting due to prolonged standing or quick rising on a hot day. The condition arises when the body's blood supply to the brain becomes insufficient.
Warning Signs of Heat Exhaustion and Heat Stroke
Heat exhaustion and heat stroke are serious forms of heat illnesses that occur when people are in extremely hot temperatures and do not drink enough water. It is crucial to recognize symptoms of these medical problems at an early stage to avoid serious consequences.
Signs of heat exhaustion
- Heavy sweating - Sweating too much is the body’s response to cooling itself down in very hot conditions. It can result in the loss of water and electrolytes, leading to dehydration.
- Dizziness or fainting - Low blood circulation and dehydration will make people feel dizzy and faint. Fainting is most likely to happen when one has been standing for a prolonged period under the sun.
- Weakness or fatigue - Individuals feel weak because they work hard to maintain normal body temperature. Even light exercise can become very tiring in the heat.
- Headaches - Excessive exposure to heat can cause either throbbing or lingering headaches. This can be made worse by the individual staying in a heated atmosphere.
- Nausea or vomiting - It can result from high temperature, leading to greater water loss through vomiting.
- Muscle cramps - Severe muscle pain due to the loss of salt and fluid through sweating is common. It normally affects the muscles of the body, such as the legs, arms, or abdominal muscles, during strenuous activity.
- Cool, clammy skin - In such a warm setting, the skin may be cool, pale, and damp due to heat exhaustion. This is an important warning sign that immediate cooling is needed.
Signs of heat stroke
- Very high body temperature - Any temperature above 104°F (40°C) is a sign of heat stroke and needs immediate medical attention.
- Hot, red, or dry skin- Skin may feel hot to the touch and appear reddened, with little or no sweating despite exposure to extremely hot conditions.
- Confusion or altered mental state - Heat stroke may affect brain function, leading to confusion, irritability, disorientation, or unusual behavior.
- Rapid pulse - The heartbeat speeds up in an attempt by the body to regulate temperature and maintain the flow of blood.
- Difficulty breathing - Shortness of breath occurs due to high body temperature and physical strain.
- Loss of consciousness - The victim may experience unconsciousness or even fainting because of severe heat stroke.
- Seizures - In extreme cases, overheating can disrupt brain function and trigger seizures or convulsions.
Importance of Hydration and Rest Breaks
Water and proper rest are essential for people who work in hot conditions and also for those who take part in vigorous exercises, as they play a major role in preventing people from being dehydrated and heat-induced illnesses, thus helping save energy and keep workers both productive and safe:
