Less than six hours of nightly sleep can lead to obesity and even death, but sleep plays an equally important role in regulating our emotions. In The Twenty-Four Hour Mind psychologist Rosalind Cartwright gives an engaging account of the history of sleep research. She skillfully weaves in her 50 years' worth of work in the field, delving into her own theories about the purpose of dreams and highlighting the importance of sleep to maintain our physical and mental well-being.
