Extreme heat is becoming more frequent in the Netherlands due to climate change, posing serious health risks, particularly for older adults. Older people are more vulnerable because their bodies regulate temperature less effectively, they are more likely to have chronic health conditions, and they may face barriers such as limited mobility, low income, or social isolation. Yet, studies show that older adults often do not take enough protective action during heat events, a pattern sometimes called the “vulnerability paradox.”
This project investigates how Dutch adults aged 50 and older perceive heat risk, what symptoms they experience during extreme heat, and which protective measures they adopt. By examining the psychological factors that drive or hinder action, we aim to identify leverage points for motivating effective heat adaptation among those most at risk. This study can inform and strengthen public health strategies (i.e., Nationaal Hitteplan), as empirical data in the Dutch context is currently scarce.
