Global Warming and Seasonal Allergies
Climate change is a global phenomenon characterized by changes in the planet that are universally considered usual. The changes can be mild or extreme regarding temperature, precipitation, and wind. Over the years, human activity has contributed to the survival and advancement of societies; however, climate and the planet's ecosystems have been under threat. Consequently, public health is also impacted especially respiratory health for people with asthma and allergies. This blog analyses the link between human health and climate change while measuring the severity of impact.
Environmental determinants of health are directly influenced by climate change. The human body reacts differently to temperatures, extreme weather events, and rising sea levels. Also, food, water, and air are compromised by changes in the climate of an environment. The severity of the public health risks depends on the age, gender, economic stats, adaptation, and behavioral patterns of a group. Any research on climate change needs to look at the sensitivity of the population, level of exposure, and the ability of the people to adapt.
Climate change impacts public health positively and negatively, with the majority of effects being adverse. Some of the positive effects are the decrease in winter deaths in extreme temperature climates. Also, there has been an increase in food production in some regions; therefore, some societies have access to new food sources. However, the majority of health impacts are harmful, with the extreme being death. For instance, excessive heat is the main characteristic of climate change. Death occurs when cardiovascular and respiratory functions are compromised by higher temperatures, especially among older people. The summer of 2002 heatwave is a real-life occurrence responsible for more than 70 000 deaths CITATION Wor18 \l 1033 (Organization, 2018). High temperatures contribute to the alteration of the ozone layer exposing individuals to other pollutants.
Also, rising temperatures contribute to changes in the allergenic pollen biology, for instance, in the Northern Hemisphere (Lewis H Ziska, 2019). The anthropogenic climate change can alter the pollen concentration in the atmosphere or extend the pollen seasons. Consequently, individuals are prone to seasonal allergies, commonly known as hay fever. Hay fever is allergic rhinitis whose symptoms are prevalent at different times of the year. The climate of an environment influences the ability of molds to release spores, while trees and flowers release tiny pollen grains. To some individuals, the immune system considers the particles like allergens, consequently releasing chemicals such as histamine into the bloodstream to defend against them.
Shifting phenological patterns becomes one of the most apparent and widely documented responses to climate change. In a warm, semi-arid ecosystem, many plant species tend to flower multiple times throughout the year. However, in temperature-limited ecosystems, there is a more defined seasonality to most phenological events. The plants tend to become dormant during winter's freezing temperatures and come out ...
