Heat-wave of record temperature in the UK, first-ever red heat warning came into effect
The UK’s first ever red warning for exceptional heat came into force at midnight on 18th July 2022, with temperatures expected to rise up to 41C (105.8F) over the next two days, breaking the country’s all previous heat records.
Passengers were urged not to travel by train from Monday as a record-breaking heatwave hits the UK, while the officials said schools should not be closed and people should be careful enough to “enjoy the sunshine”. Transport services were expected to be disrupted on both Monday and Tuesday, asking people not to travel unless absolutely necessary while some train tracks were painted white to prevent from buckling with heat.
The UK’s first red extreme heat warning was issued across a large part of England for Monday and Tuesday. Firefighters of London also faced one of their hard time ever on Tuesday 19th July as several fires and record-breaking temperatures stretched their resources to the limit. Temperatures in the UK exceeded 40 degrees Celsius (104 degrees Fahrenheit) for the first time on the 19th of July Tuesday, making it the country's hottest day ever recorded.
It was a dry year in most parts of England. As the sun shines on the ground, then dry soils cannot release their energy through the evaporation of moisture, which caused more of the sun’s energy to go into heating the air, further amplifying the temperatures in the UK," this is called the soil moisture feedback by the climate scientists.
Heat waves caused by climate change and how to prepare for it
We should not make our communities much congested as heat waves due to climate change impacts are already in progress. Many communities are already working on climate-sensitive health issues. When it comes to managing the health threats associated with extreme heat, there are approaches that we know work: Heatwave early warning systems can protect people by communicating heat wave risks and suggesting protective actions. Warning systems are much cheaper in cost than treatment expanses of heat illnesses. Heat alert systems help alarm and inform to take preventive action, like making cool areas where the public can gather in emergency for relief from the heat. Air conditioning is the top protective factor against heat waves, and it is also an essential health resource for populations. Staying hydrated and avoiding outdoor exercise can protect us from the adverse effects of heat waves. Providing easy access to drinking water in the public area, swimming pools, and sprays can help keep people cool during periods of heat waves while improving the building’s ability to protect against heat. Green roofs (roofs with plant cover) and trees help reduce temperatures and improve energy efficiency. Urban forests, including street trees and wooded areas, also help reduce air temperature.
What is heat wave?
Actually, the heat wave is the name of a condition in which air temperature becomes lethal to the human body when exposed. If we explain it quantitatively, it is defined on the base of the temperature thresholds over a region’s actual temperature or we can say its departure from normal. In some countries, it is explained in terms of the heat index based on temperature and humidity or based on the extreme percentile of the temperatures.
Health Impacts of Heat Waves?
The health conditions due to Heat Waves usually consist of dehydration, heat cramps, heat exhaustion, and heat stroke. Given below the symptoms and signs of heat stroke:
- Heat Cramps: swelling and Fainting generally accompanied by fever below 39 degrees Centigrade (102 degrees Fahrenheit.
- Heat Exhaustion: Fatigue, weakness, dizziness, headache, nausea, vomiting, muscle cramps, and sweating.
- Heat Stroke: Body temperatures of 40*C i.e. 104*F or more along with delirium, seizures, or coma. This is a potentially fatal condition.
The measures everyone should take to minimize the impact of the heat wave
- Be careful and avoid as much as you can going outside in the sun, especially in noon 12.00 to 3.00 p.m.
- If you have to go outside take a continuous mist spray water bottle filled with fresh water with you and frequently spray your face and open body parts with it to keep your skin well moisturized, also spray your pets and birds with it. These advanced spray bottles are widely used nowadays.
- Drink adequate water if possible, even if you are not thirsty
- Wear lightweight, bright-color, loose cotton clothes. Use sunglasses, an umbrella or hat, shoes, or chappals while going out in sun.
- Avoid hard activities and work outside when the temperature is high from noon 12:00 to 03:00 pm.
- While traveling, carry water with you.
- Avoid consuming alcohol, tea, coffee, or carbonated drinks, which causes to dehydrate the human body.
- High-protein food should not be consumed.
- If working outside, use a cap or hat and also use a damp cloth on the head, neck, face, and all open parts.
- Do not leave children or pets in parked vehicles
- If you feel faint or ill, see a doctor immediately.
- Keep your pets, birds, and cattle in shade and provide plenty of water for them to drink.
- Keep your home cool by using curtains, sunshades, and open windows at night for ventilation.
- Use fans, and damp clothing and take bath in cold water frequently.
