The world is ever evolving and with this evolution comes problems like increasing pollution and a changing climate, environmental aspects are becoming really significant. It is obvious how these environmental changes are influencing public health, even beyond the immediate concerns about the state of the air and water. Learning how environmental changes contribute to the rising incidence of skin cancer is very important for the development of successful prevention measures and medical techniques.
The Sun
UV Rays are being blocked by the stratosphere. Climate change increases the greenhouse gas emissions and the changes in air circulation may contribute to ozone depletion indirectly by increasing the quantity of UV radiation that reaches the Earth. UV radiation levels may be negatively impacted by changes in cloud cover patterns brought on by climate change. While additional clouds can filter UV rays, some cloud forms can also scatter UV rays intensifying them at the ground. Because of greater numbers of wildfires, dust storms, and industrial pollutants, climate change may deteriorate the quality of the air. Although these pollutants have the ability to filter UV light, they may also react with it to produce harmful effects.
Climate Change
People naturally tend toward activities that give relaxation from the heat as global temperatures rise such as spending time outside and engaging in sun-seeking activities like swimming, tanning, and going to outdoor events. A feedback loop is produced because more people spending time outside may contribute to heat trapping through a variety of ways. Weather patterns are changing due to global warming. With certain areas seeing longer and hotter summers, this encourages people to seek out the sun even more. In addition to providing an instant break from the heat, some studies show that individuals actively seek out sunshine for its ability to improve mood and produce vitamin D. Regardless of the weather, more people may choose to engage in outdoor activities if they see sunshine is helpful.
Pollution
Fine Particulate Matter or PM can cause many kinds of health issues since they are tiny enough to enter the circulation and lungs. They can also harm the skin, raising the risk of skin cancer and causing early ageing. Skin cancer can be significantly influenced by chemical contaminants such as heavy metals and polycyclic aromatic hydrocarbons (PAHs). Skin cells’ DNA can be directly harmed by PAHs which are created when organic materials (such cigarette smoke and exhaust from cars) burn incompletely. This harm may result in mutations that fuel cancer’s unchecked cell proliferation. Free radicals are unstable chemicals that harm DNA and healthy cells. Both heavy metals and PAHs may produce these molecules. This process known as oxidative stress, can hasten the ageing process of the skin and increase inflammation which may stimulate the growth of cancer. The skin’s immune system may be weakened by exposure to particular pollutants which may reduce its capacity to detect and eliminate abnormal cells that have the potential to develop into cancer. There appears to be a relationship between rising pollution levels and the number of skin cancer cases in cities that are growing and becoming more urbanised. As previously mentioned, fine particulate matter, nitrogen oxides and PAHs constitute major causes of air pollution in cities. There are often fewer parks, trees, and other green spaces in urban settings which decreases access to natural shade and increases UV exposure. Poorer results and delayed diagnosis can often be the result of lower-income groups in cities having restricted access to healthcare, preventative measures and knowledge about skin cancer.
Public Health Initiatives and Mitigation Strategies
Sun-Safe Urban Design
Due to changes in the global environment such as rising temperatures, changing weather patterns, and increased exposure to UV radiation, sun-safe urban planning is now necessary. We can develop surroundings that both promote general health and well-being and lessen the influence of climate change on skin cancer rates by implementing strategic design features into our communities.
Enhance Environmental Infrastructure
Shade is provided by urban parks, community gardens, and street trees which lowers UV exposure for outdoor activities and pedestrians. And trees contribute to the cooling of urban heat islands, reducing outside temperatures and improving outdoor living.
Vibrant, Shaded, and Friendly Streets
Protected bike lanes, walking routes designated specifically for walking and wider sidewalks can promote physical activity as well as lower air pollution and greenhouse gas emissions by encouraging walking and cycling. By carefully positioning awnings, canopies and pergolas, people may find shade along sidewalks and in public spaces particularly during the warmest times of the day.
Environment-friendly Building Designs
It is possible to considerably minimise heat gain and UV penetration indoors by promoting buildings with south-facing facades that have overhangs, louvres, or other sun-shading elements. This will result in cooler and cosier places to live and work areas. Promoting the use of reflective materials on the outside of buildings could help in heat deflection from the sun making cities even colder.
Education and Community Participation
Campaigns for public awareness may teach the public about the dangers of UV radiation and encourage sun safety precautions like using sunscreen, covering up, and wearing protective clothes. Community gardening and urban farming projects may promote outside activities, raise knowledge of sun protection and make fresh fruit more accessible. Children and adults may learn about sun protection through educational programs in schools and community centres which will also provide them the power to make health-related decisions.
It is important to acknowledge that sun-safe urban design is just a single piece in reducing the adverse effects of climate change on the incidence of skin cancer. Long-term solutions need addressing the core cause, human climate change, emissions reduction and the switch to renewable energy.
