All About Sleep – Why We Sleep

“Why We Sleep” written by Matthew Walker, PhD was one of my top 20 books I read in 2022. Matthew Walker, PhD is a professor of neuroscience and psychology at UC Berkeley and director of its Sleep and Imaging Lab. He has published more than a hundred scientific studies. This book was PACKED with information, and I will share some of the research I found most fascinating.

Contrary to what most people believe, you cannot “catch up” on sleep by sleeping in on the weekends. It takes much longer, and consistent sleep is vital. Getting too little sleep across the adult life span significantly increases your risk of developing Alzheimer’s disease and increases the risk of cancer development. Also, the less you sleep, the more you are likely to eat, and you increase your probability of gaining weight and developing Type 2 diabetes.

Poor sleep quality increases the risk of cancer development, and, if cancer is established, provides a virulent fertilizer for its rapid and more rampant growth.

Dolphins, whales, and some birds can sleep with half a brain at a time and remain alert with the other half! In flocks of birds, with the exception of the birds at the end of the line, the rest of the group will allow both halves of the brain to indulge in sleep, while the end of the line has 1/2 brain sleeping and 1/2 alert for threat detection! Wow!

We use the term “half-life” when discussing a drug’s efficacy (length of time it takes for the body to remove 50% of a drug’s concentration). Caffeine has an average half-life of 5-7 hours, so any caffeine after noon will impact your sleep!

Decaffeinated does NOT mean uncaffeinated. One cup of decaf usually contains 15-30% of the dose of a regular cup of coffee!

The different sleep stages play different roles in information processing. The wake state is focused on reception – experiencing and constantly learning the world around you. The NREM sleep state is focused on reflection – storing and strengthening those raw ingredients of new facts and skills. The REM state is focused on integration – interconnecting these raw ingredients with each other and with past experiences, resulting in innovative insights and problem-solving abilities.

Some signs of insufficient sleep include not being able to get up on time without an alarm, having to read and reread sentences at your computer, and having standard ADHD symptoms of irritableness, moodiness, being more distractable and unfocused during the day, and having mental health instability.

Vehicle accidents caused by drowsy driving exceed those caused by alcohol and drugs combined! Driving drowsy is worse than driving drunk in that being drunk results in late response times in braking and maneuvering, whereas falling asleep results in not reacting altogether.

5 key factors have powerfully changed how much and how well we sleep: constant electric light/LED light, regularized temperature, caffeine, alcohol, and a legacy of punching time cards. This book mentioned that Edina, MN schools were one of the first to experiment with shifting the start time and reported much higher scores on SATs. Other schools have reported better GPAs.

This book also briefly discussed some sleep disorders such as insomnia and narcolepsy. Fatal familial insomnia is a rare sleep disorder caused by a mutation on chromosome 20, which makes the protein insoluble. When it converts, the protein causes plaque to form in the thalamus, which is the region responsible for the regulation of sleep. Fatal familial insomnia has no treatments or cures! I did find it interesting that Prazosin, a medication used to treat high blood pressure, is used in the treatment of repetitive trauma nightmares.

Tips for better sleep:

  1. Stick to a sleep schedule. Wake up and go to bed at the same time each day, including weekends.
  2. Try to exercise at least 30 minutes on most days but not later than 2 or 3 hours before your bedtime.
  3. Avoid caffeine in the afternoons/evenings and avoid nicotine.
  4. Avoid alcoholic drinks before bed. Heavy alcohol ingestion robs you of REM sleep and disrupts your breathing at night.
  5. Avoid large meals and beverages late at night.
  6. If possible, avoid medications that delay or disrupt your sleep. Some commonly prescribed heart, blood pressure, and asthma medications, as well as some over-the-counter and herbal remedies for coughs, colds, and allergies can disrupt sleep patterns. Talk to your doctor or pharmacist if you are having trouble sleeping to see if any of your medications may be contributing.
  7. Don’t take naps after 3 p.m.
  8. Relax and unwind before bed. A relaxing routine, such as reading or listening to music, should be part of your nightly routine.
  9. Take a hot bath before bed. The drop in body temperature after getting out of the bath may help you feel sleepy.
  10. Your bedroom should be dark, cool, and gadget-free.
  11. Get sunlight exposure during the day. Daylight is key to regulating daily sleep patterns.
  12. Don’t lie in bed awake. If you can’t fall asleep after 20 minutes, get up and do a relaxing activity until you feel sleepy. The anxiety of not being able to sleep can make it harder to fall asleep.

I learned SO much from this book, and I am just covering the tip of the iceberg. I definitely don’t currently practice all of the tips mentioned in this book, but I look forward to implementing some of them for better sleep and more energy!

I look forward to reading, learning, and sharing more with you soon!
