Sleep is vital to the way we learn, remember and forget, to how we feel about family and partners, our wellbeing, and our mental and physical health. It is essential for life itself. In Nodding Off, renowned sleep researcher Alice Gregory explores every aspect of sleep, from the different stages of sleep and how our sleeping patterns change throughout our lives, to what happens when things go wrong and getting some shut-eye becomes more of a trial than a pleasure.Using cutting-edge findings in the field, Gregory tackles the big questions, such as:- How do things that happen before we are even born affect our sleep?- What sleep problems should raise a red flag in children?- How do genes influence the way we sleep?- What are the consequences of sleep problems in the elderly?- Why are scientists turning to sleep disorders such as sleep paralysis to try to understand paranormal experiences?Most of us spend a large portion of our lives asleep without ever thinking about why we do this.
