OBJECTIVE To examine the impact of weather and seasonality, as consequences of climate change, on mental health.
METHOD The main hypothesis is that both weather and seasonality have significant effects on mental health. To investigate this hypothesis, the study employed a quantitative analysis using a questionnaire. The study investigated the impact of cold and hot weather on mental health in Greece through a quantitative survey. A sample of 120 citizens completed a questionnaire focusing on their mental health once during high temperatures and once during low temperatures.
RESULTS During periods of high temperatures, respondents were more likely to report feeling unmotivated, while levels of stress, depression, and anxiety remained low. Additionally, they were more likely to agree that they had achieved the important things they wanted in life and that their life satisfaction was above average. Finally, the study found that participants exhibited statistically significant differences in stress, anxiety, and life satisfaction levels between the two temperature conditions. Specifically, they reported higher levels of stress and anxiety during high temperatures and higher levels of life satisfaction during low temperatures.
CONCLUSIONS This study emphasized the urgent need for global leaders to accelerate action to reduce greenhouse gas emissions to avoid these unjust burdens on society while supporting communities to adapt.
Key words: Anxiety, Climate change, Depression, Mental health, Seasonality, Stress, Weather conditions.
