Blake O'Sullivan

Straight away O'Sullivan does not want you to think he is a licensed medical professional. He was an athlete looking to improve his performance and had an ah-ha moment about sleep. His advice is mostly common sense: stay away from caffeine and your phone before bed; expose yourself to light as soon as you wake up; take cold showers in the mornings and warm showers in the evening; remove all light sources from your bedroom and so on. O'Sullivan uses a lot of analogies to get his point across. show more He also repeats himself. Towards the end there was a lot of redundancy surrounding the checklists for each week.
I have always heard the advice about how to get a good night's sleep, but thanks to 4 Weeks to Sleep Mastery, I have a better handle on the science behind the advice. I also appreciated O'Sullivan's breakdown of information into two categories: simplified and advanced.
4 Weeks to Sleep Mastery is short, under 200 pages. O'Sullivan could have added more depth to his book by including advice for the outliers. What about the people who are at work before the sun makes its appearance? What about seasonal changes when the sun doesn't always rise before you do? I would have liked to see more information regarding diet and special circumstances, like traveling or having a chaotic life event (new baby, job loss, foster puppies) that keep you up at night. show less

A young cricket player from New Zealand is wondering how he can improve his performance by getting the best possible sleep.
The result of his analysis provides concise yet in-depth, practical guidance on how to better align one’s circadian rhythm with the “natural flow of things.”
Since reading it, I now stand on my balcony every morning and watch the sun rise. Well done! Greetings from Austria!
