“Global warming is bringing more frequent and severe heat waves, and the result will be serious for vulnerable populations,” said Dr. Amanda Staudt, National Wildlife Federation climate scientist.
According to the National Disaster Management Authority, a weather condition is declared heat wave when the temperature crosses 40° C for plains & 30° C for hills. The worst heat wave hit Russia in 2010 killing over 50000 people. India’s worst yet was witnessed in 2003, with a toll of at least 1,900.
Heat exhaustion is a relatively common reaction to severe heat and can include symptoms such as dizziness, headache and fainting. The systems in the human body that enable it to adapt to heat become overwhelmed. When a person is exposed to heat for a very long time, the first thing that shuts down is the ability to sweat. When perspiration is dried by the air there is a cooling effect on the body. Once a person stops perspiring, in very short order a person can move from heat exhaustion to heat stroke.
Heat wave can severely impact your health, its effects manifesting as ederna (swelling) and syncope (fainting) generally accompanied by fever below 102 degrees Fahrenheit, fatigue, dizziness, headache, nausea, vomiting, muscle cramps. In extreme cases, one could even be have heat stroke, whose symptoms include delirium, seizures or coma. This is a potentially fatal condition.
With proper precautions and awareness, you can easily survive the heat waves.
