A heat wave is a prolonged period of excessively hot weather, which can last for several days or even weeks. Heat waves typically occur when a high-pressure system causes hot air to be trapped under a layer of cool air, preventing it from dissipating.
During a heat wave, temperatures can rise well above the seasonal average, and the air can feel heavy and humid. This can lead to a range of health risks, particularly for vulnerable populations, such as the elderly, young children, and people with pre-existing health conditions.
The health risks of heat waves include dehydration, heat exhaustion, heatstroke, and other heat-related illnesses. The high temperatures can also worsen existing health conditions, such as asthma and cardiovascular disease. Heat waves can also lead to power outages, as demand for electricity for cooling increases.
To protect against the risks of heat waves, it is important to stay cool and hydrated, avoid prolonged exposure to the sun, and take breaks in air-conditioned or shaded spaces. It is also important to check on vulnerable individuals, such as elderly relatives or neighbors, to ensure that they are staying cool and hydrated. In addition, measures such as providing cooling centers and public education campaigns can help to reduce the health risks of heat waves.
