Experts of every kind are queuing up to warn us that lack of sleep, or the wrong kind, will bring down a bewildering array of dire consequences.

Heather Darwall-Smith's message in this book is simple: don't panic!

Humans are biologically programmed to sleep, and by interrogating all the factors - sociological, physiological, neurological, and psychological - that might be impeding this innate instinct, each of us can work out the changes we can make in our own lifestyles to allow ourselves to sleep naturally again.

This book demystifies the bewildering data around sleep by combining science with natural self-help techniques.


Inside the pages of this illustrated guide to sleep, you'll discover:

- A visual approach to understanding the science of why and how we sleep through info-graphics, graphs and diagrams that unpick the data and present the facts in an easy-to-follow format
- Proven techniques and strategies for better sleep from the author - based on extensive clinical practice and drawing on the most up-to-date evidence from scientists around the world
- The latest research and evidence to debunk the myths and misconceptions around sleep


Heather Darwall-Smith has combined her research findings, clinical expertise, and curated techniques to create a uniquely visual approach to explaining the interrelated factors that make up our sleep habits. She also provides natural techniques to deal with these underlying causes. Humans are biologically programmed to sleep, Heather encourages each of us to work out the changes we can make to our lifestyles to nourish our body clocks for us to sleep naturally again.

The Science of Sleep provides in-depth answers to questions about sleep challenges and exposes myths and fads using science that is accessible to all. Armed with facts, this book equips readers to take control of their choices, understand and transform their sleep habits one night at a time.

My dogs favorite toy so far in two years
Color: C) 4" 2-Pack (Bacon)
I use this with my medium sized dog. These are large for him but that's what I want so I don't ever have to think about them being too small or a swallow hazard. He has been through A LOT OF TOYS in the last couple years, but nothing, NOTHING has he loved as much as these. His favorite used to be squeaker balls. Then his favorite was crackle balls. But he will gladly ignore both for this one. I don't know if it's the bacon flavor or what, but he go nuts for it.

Durable Rubber Bone Toy for Aggressive Chewers
I got this rubber bone chew toy in purple (size large) for my dog, and it's been a solid addition to his toy rotation. What I Liked: The bacon flavor is a huge hit. My dog was immediately interested in this toy and goes back to it regularly, which speaks to how appealing the scent is to him. The natural rubber material is tough and has held up well to his aggressive chewing - it's designed for heavy chewers and delivers on that promise. The textured surface is great for dental health. I can see how it helps clean his teeth as he chews, and the grooves are deep enough that you could add dog toothpaste for extra cleaning power. It's a functional toy that serves multiple purposes beyond just entertainment. The rubber material is softer than hard nylon toys, which gives me peace of mind that it won't damage his teeth during extended chewing sessions. It's still plenty durable but has some give to it that makes it safer. This toy genuinely keeps him busy and engaged. It helps redirect his chewing instincts away from furniture and other household items, and it seems to help with anxiety when I need to leave him alone for a bit. At $8.99 (down from $15.99), this is an excellent value for a durable, functional chew toy. What Could Be Improved: While it's marketed for all sizes from small to large breeds, I think it works best for medium to large dogs. Small dogs might find the large size a bit cumbersome. The bacon scent is strong initially, but it will fade over time with use and cleaning. Also, we all know it's a little... interesting looking haha. Overall: This is a high-quality, durable chew toy perfect for aggressive chewers. The bacon flavor, dental benefits, and tough construction make it a winner. It keeps dogs engaged, helps maintain dental hygiene, and redirects destructive chewing behaviors. At under $9 (well, it is right now, at least), it's a great value and makes an excellent gift for any dog owner dealing with a heavy chewer. Highly recommended.

The Purple Power Chew My Dog Thinks Is His Life’s Mission
I bought this purple rubber bone hoping it would survive longer than the usual 10 minutes my dog needs to destroy a “durable” toy. Shockingly, this one is still alive and thriving. Honestly, I think it might outlive me. The material is tough enough for aggressive chewers, but still bouncy and fun, which means my dog is entertained AND my furniture gets a break. It’s the perfect size for medium to large dogs, and it keeps mine busy like he’s working an important full-time job. He tosses it, chases it, gnaws on it with total devotion… and somehow it barely shows a scratch. The purple color is a bonus, easy to spot in the yard, and it makes him look very fashionable in his ferocious-chewer era. If your dog believes every toy is a challenge to conquer, this chew toy just might be the worthy opponent they’ve been waiting for. 💜🐶

Not my husky's favorite
Size: Large
No bounce, it's too hard and heavy. My husky only uses it once in a while, it is not his favorite thing to chew on.

Better Than Most, But Still No Match for My Super Chewer
This is a decent chew. It’s made of a softer rubber material and has little to no odor, which I appreciate. It’s been about a week, and while it’s still technically in one piece, it’s starting to show some cracks and tiny puncture holes. Now, keep in mind, my 100-lb pit mix Scooby Doo is a full on chew and destroy hound. If it can be chewed, he’ll find a way to shred it to bits. This toy held up longer than a lot of others but still didn’t make the “indestructible” cut in our house. He likes it, but it’s not his top pick, probably why it’s still alive. Overall, it’s a good toy for the price. Probably not for extreme power chewers like Scoob, but it’ll hold up fine for most dogs and give you a little peace and quiet for a while. Do give it a try, Scooby Doo is a chewer in a class of his own, the fact that this has held up past a one 15 minute session is amazing in itself.
