Book excerpt: Do you feel happier on a sunny day? Are you afraid of thunderstorms? Are you dreaming of a White Christmas? The Psychology of Weather explores our relationship with the weather, and how it can affect our mood, behaviour, and lifestyle. The book sheds light on our preoccupation with this natural phenomenon, providing insights into how the weather on the day we were born can directly affect our intelligence and personality, and explore such surprising findings that suicide rates peak in the spring and summer. When the weather affects everything from our buying behaviour, to the jobs we do, The Psychology of Weather shows us that understanding and appreciating the weather can improve our well-being and contribute to human survival.
