Head in The Clouds: How the Weather Affects Our Minds and Mental Health
'Fun, fascinating and original – a gust of fresh air!' TRISTAN GOOLEY, author of THE SECRET WORLD OF WEATHER
My brand new book looks at how weather changes how we think, sleep, feel, behave, and our mood. It affects our mental health. We can use the weather to improve our mood and make us happier, more relaxed, healthier people.
Ever wondered why:
Storms terrify so many people?
Rainy weather makes us feel hungry?
We get the winter blues?
Some people become very depressed in summer?
Heat increases aggression and violent crime?
A rainbow or aurora can affect us profouncly and change our lives for the better?
How temperature changes the way we speak?
Why children misbehave when it's windy?
... and much else.
