The power of sleep in learning is discussed.
Sleep is important for mental health, but what do the numbers say? Many people have not unlocked their potential.
Sleeping well can boost your learning by 20% to 40%. The book says so.
One hour of less sleep every day is a reality for many people and students. It is hard for people who have been sleep deprived for a long time to know they are not getting enough sleep. According to the book, just 1 hour of less sleep for 10 nights is enough to make you perform like a drunk. Driving, learning, reaction time, and so on are included.
The mechanics of sleep are related to learning. How does sleep affect learning?
During sleep, the memories can either be transferred from the hippocampus to the neocortex or they can be removed. As we learn new stuff, they are mostly stored in the hippocampus. The brain region has a relatively small amount of space to store memories.
A lack of sleep results in your hippocampus not being completely emptied and your memories being strengthened. This makes it harder to remember and learn new things. For more information on memory consolidation, see: Memory consolidation
If you had to choose between earning $80,000 a year while working normal hours and getting good sleep or $140,000 while working insane hours and only sleep 6 hours a day, what would you choose? Productivity and sleep.
What is the reason? When you have slept well, you are more creative because you make less errors. The majority of people would choose the latter. The book teaches that you can make $140,000 in the long-term if you sleep well and work hard.
Quality should not be sacrificed for quantity. This is important for studying and learning.
Bill Gates wrote a review on the same book with tips to improve sleep.
