Why We Sleep – By Matthew Walker

Why We Sleep – By Matthew Walker

This book will change your perspective and approach towards sleep. The saying- “There is plenty of time to sleep when we die” will no more be upheld after reading this book. The author gives an excellent description of the factors affecting sleep, the circadian rhythm, and other biological processes involved in sleep. The book’s most attractive element is written in straightforward language that everyone can easily understand. There are no complicated technical words, and even those who do not have the slightest idea of human physiology can quickly grab the contents. I have taken some of the topics, which I felt to be essential, and mentioned below.

  • What is circadian rhythm, and how it helps in sleep?
  • The role of our biological clock in controlling sleep and how it functions.
  • Sleep requirement for different species and why is it so
  • The effect of metabolism in sleep.
  • What is melatonin, and how does it function.
  • Jet lag, its cause, and implications.
  • Role of caffeine in awakening and its complications.
  • Different stages of sleep, importance, and the duration of each of them.
  • Why do we dream, and when do we dream.
  • Sleep deprivation and recovery nights.
  • The changes in sleep patterns as we grow from a baby to adulthood and old-age.
  • Do we require less sleep as we grow old?
  • Relation of proper sleep and performance of athletes.
  • Effects of sleep deprivation in mood swings and emotions
  • Sleep and the ability to remember and recall events and learnings.
  • How does even the slightest sleep deprivation affect the overall performance of a person?
  • Long-term effects of sleep deprivation.
  • Sleep deprivation and sleep-related disorders.
  • Psychiatric illness and lack of good sleep.
  • The relationship between sleep and diseases like cancer, stroke, diabetes, and cardiovascular ailments.
  • Adverse effects of insufficient sleep in children and its long-term complications.
  • Sleeping pills- Does it aid in sleep.
  • Adverse effects of sleeping pills.
  • The financial loss incurred due to insufficient sleep.
  • Effects of improper sleep, in society, at the workplace, and in life span.
  • Methods to be adopted to get proper sleep.

The above are some of the points that I felt to highlight. However, the entire book is a storehouse of information and eye-opening facts about sleep, most of which are neglected. After reading the book, we will have a better sleep approach and will no more ignore this life-saving function.
