How to maintain your health in a drought

What constitutes a drought? A drought is an extended period of dry weather lacking rainfall. In recent decades, there has been a global increase in the frequency of drought occurrences. With the onset of climate change, elevated temperatures are exacerbating aridity, not only within the United States but also worldwide. Recognizing the detrimental effects of drought where you reside and taking appropriate measures to safeguard your well-being is crucial.

How do droughts impact our global ecosystem? The ramifications of droughts on both the environment and human health are multifaceted. For instance, water scarcity resulting from droughts can adversely affect agricultural output, livestock, and aquatic ecosystems. This scarcity disrupts food supplies, leading to price hikes and exacerbating issues of food insecurity and malnutrition. Additionally, the depletion of trees during severe droughts not only diminishes their role in providing shade and combating climate change, but also renders certain regions uninhabitable, promoting climate-induced migration.

In what ways do droughts pose health risks? The adverse effects of drier conditions on health are manifold, ranging from subtle to significant.

Droughts contribute to the proliferation of diseases:

- Reduced water flow during droughts can lead to the accumulation of harmful water contaminants in water bodies, elevating health risks for individuals reliant on these sources.

- The formation of harmful algal blooms due to stagnant water can result in skin irritations and gastrointestinal issues.

- Stagnant water also serves as breeding grounds for disease-carrying mosquitoes, heightening the risk of vector-borne illnesses.

Furthermore, dwindling water levels coupled with increased temperatures facilitate the proliferation of pathogens, including viruses and bacteria, in drinking water sources, posing a particular concern for those relying on private wells.

Moreover, farmers may resort to recycled water for irrigation during droughts, potentially introducing infectious agents like E. Coli or Salmonella to crops.

Droughts contribute to air pollution:

- Dry conditions during droughts contribute to the outbreak of wildfires, endangering local communities and dispersing harmful smoke over vast areas, depending on wind patterns.

- Dust storms, another consequence of drought, transport allergens and microorganisms, exacerbating respiratory illnesses such as asthma and COPD, and increasing the risk of infections like Valley fever.

Additionally, diminished availability of renewable hydropower energy during dry spells may compel utilities to resort to more-polluting fossil fuel sources, intensifying greenhouse gas emissions and exacerbating climate change.

Taking proactive steps to mitigate the impact of droughts:

- Implementing measures to conserve groundwater resources, such as treating wastewater for reuse and exploring desalination technologies.

- Establishing initiatives like the National Integrated Drought Information System (NIDIS) in the United States to coordinate drought research, monitoring, and early warning systems.

To safeguard health during droughts:

Ensure adequate hydration and monitor the quality of drinking water, particularly for those reliant on well water.

Stay informed about harmful algal blooms and air quality advisories.

Exercise caution during recreational water activities and adhere to wildfire prevention guidelines.

Adopt water conservation practices recommended by the Environmental Protection Agency (EPA) while maintaining essential hygiene practices. To safeguard health during droughts:
