Preventing cold-related morbidity and mortality in a changing climate

Area of Science:

• Environmental Health
• Public Health
• Climate Change Adaptation

Background:

• Increasing global temperatures lead to more variable winter weather patterns.
• Cold weather periods are associated with excess morbidity and mortality.
• Understanding vulnerability to cold weather is crucial for public health.

Purpose of the Study:

• To review evidence on temperature variability, health outcomes, and cold weather adaptation strategies.
• To identify individual and contextual risk factors for cold weather vulnerability.
• To present actionable adaptation strategies for vulnerable populations.

Main Methods:

• Critical review of existing epidemiologic and adaptation literature.
• Assessment of individual and contextual risk factors for cold weather vulnerability.
• Identification of populations most susceptible to cold weather variations.

Main Results:

• Populations most vulnerable include the elderly, rural residents, and those in moderate winter climates.
• Cold-related morbidity and mortality are preventable through adaptation.
• A range of adaptation strategies exist at individual, building, and neighborhood levels.

Conclusions:

• Vulnerable populations require targeted outreach and education on cold weather protective adaptations.
• Future research should integrate building energy/thermal comfort models with epidemiological data.
• Quantifying adaptation strategy impacts is essential for effective climate change adaptation planning.
