Protect Yourself From Searing Heat

In recent weeks, Kathmandu has become hotter than before, reaching its peak during the summer season. In the past three years, the Kathmandu Valley has experienced temperatures as high as 35 degrees Celsius, and this trend can be observed in other parts of the country as well. 

The "urban heat island effect" could be the reason for Kathmandu's higher temperatures. This happens when cities get hotter than nearby countryside due to human activities like building, transport, and energy use including the city’s high population, density, heavy traffic and lack of green spaces. Additionally, climate change, a global phenomenon, is causing temperatures to rise worldwide. Kathmandu may be experiencing the effects of this trend for year, resulting in hotter temperatures compared to previous years.

With the increasing heat, it is important to be aware of the health risks associated with excessive heat like exhaustion, cramps, and stroke. These conditions can be especially risky for older adults, children, and individuals with certain medical conditions. Exhaustion leads to heavy sweating, weakness, dizziness, and nausea. Heat also causes painful muscle cramps while heat-induced stroke generates symptoms of confusion, seizures, and loss of consciousness. 

Similarly, mosquito-borne diseases such as dengue fever and malaria can also be a concern during summer months. The diseases are transmitted by mosquitoes that are common in the region, particularly during the rainy season.  It's essential to protect yourself from mosquito bites, such as wearing long sleeves and pants, using mosquito repellent, and sleeping under a mosquito net. Additionally, it's important to remove puddles around your home, as this can be a breeding ground for mosquitoes.

Heat rash, a common skin condition in summer, is caused by excessive heat and sweating. It appears as small red bumps and can be itchy. The rash occurs when sweat glands get clogged, trapping sweat under the skin. It commonly occurs in areas where skin rubs together. To prevent heat rash, it's important to stay cool and dry by wearing loose, breathable clothing and avoiding excessive sweating.

Staying hydrated during the summer is crucial for maintaining good health and well-being. We must drink an adequate amount of water throughout the day, even if you don't feel thirsty. People must ensure to use sunscreen with a high sun protection factor (SPF) to protect your skin from damaging UV radiation.

Similarly, it is also necessary to stay away from food that are oily and heavy in fat. Salads made with fresh produce, such cucumber, watermelon, and mint, are excellent choices. People should wear comfortable, light-coloured, loose-fitting garments made of cotton or linen or other breathable materials during these summer days, which promotes airflow and aids in controlling body temperature.

It's crucial to be aware of climate change's impact and promote sustainable practices as greenhouse emissions have also contributed to rise in global temperature. The people must follow the advice of health experts so as to avoid the effects of heat risks.
