It’s not always compatible with our modern lives, but remains an essential function, vital for our health, well-being and daytime functioning. In this groundbreaking new book, Dr Merijn van de Laar investigates the origins of sleep based on archaeological findings and anthropological studies in contemporary hunter-gatherers, looking at the major discrepancies between our primordial bodily needs and our current sleep-inhibiting behaviour.Cave dwellers lived in balance with the forces of nature. They had adapted perfectly to environmental influences such as light, temperature and seasonal variations. The way they ate and moved during the day must have had a positive effect on sleep quality. We need to look to their example, and adjust our eating, exercise, light, temperature and, last but not least: our expectations towards sleep. By taking on board the ancient wisdom of our ancestors, we will improve the quality of our sleep, the way our bodies were designed to do it.Dr. Merijn van de Laar's How to Sleep Like a Caveman is a best-in-class exploration of the intersection of psychology, medicine, and evolutionary science. This non-fiction book offers practical self-help strategies for stress and fitness management, all aimed at improving sleep quality.For fans of Dr. Guy Meadows (The Sleep Book), Rolf Dobelli (The Art of Thinking Clearly), Bill Gates (Source Code), and Daniel J.
