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.

Great for chewing but very sharp and mangled in a few days
Color: Blue Gator, Size: 1 Count, Color: Blue Gator, Size: 1 Count
I thought this was a fantastic idea having baking soda added for fresh clean teeth while enjoying a new toy. I wanted to review 2 main things about this. First, if my dog enjoyed this toy. That answer would be yes absolutely! She is chewing it as I’m writing this right now. She can spend a good amount of time chewing away on this and it keeps her busy without having to use a rawhide treat which we only try to use if we re going to be gone for longer then 4 hours. The kids love playing fetch with her and she stays engaged the whole time. It is very heavy and when being thrown can become a weapon so I always supervise! Last, the durability of the toy. So it is durable but not completely. As you can see the toy got very sharp where she has been chewing it and I’ve even noticed a little blood on it which means it’s cutting her gums. It wasn’t a large enough amount for me to take it away. It is still almost the exact same size but maybe after a month I will re edit this for more accurate on durability since it’s only been about a week that she has gotten it. Overall, I would recommend this toy it’s a great price and keeps her attention a lot more then other toys I spent twice the amount of money on!

Too Hard
Color: Blue T-Bone, Size: 1 Count
I have a pit puppy, 20 lbs, who loves to chew. She's huge for her age, and I wanted to get her a new toy. I bought two different toys, hoping she would like one. The other toy was a hit, they both jumped at it and were excited about it, probably because it had rawhide rings that went with it. This one was immediately thrown to the side, even though my pit loves to chew on non edible toys. I think this one was just too hard, because both her, and my Chihuahua-Jack Russell, weren't interested. It didn't have any smell to attract them, which is why I bought it, because they love peanut butter stuff. I'm not going to go as far as to lick it and taste it... I'm pretty sure it won't taste like peanut butter, either. I feel so bad for my little pittie, she's just sitting here with a sad look on her face because my other dog stole the fun chew toy. I've immediately ordered another of one of those so they both have one, but I've just money wasted on this one. It's probably better they don't like it, I'd be worried about them breaking their teeth. I know it's supposed to be for power chewers, but it has no give whatsoever, just extremely hard, shiny plastic. It's useless, unless you're planning on filing it into a point and making a prison shank. Maybe you can leave it in front of the fridge for your SO to step on in the middle of the night when he goes to steal your almond milk. I'll figure out some way to use it. I did dip it into my boyfriend's peanut butter jar to let my puppy lick it, but I can do that with a spoon. I wanted her to feel like she got something, maybe my other dog will let her have a turn with the fun toy after awhile. That's the only reason I gave it 3 stars. You can dip it in peanut butter and I was being generous.

Can become brittle with sharp edges with use.
Color: Blue T-Bone, Size: 1 Count
Our little dog loved chewing this, however after chewing the toy became jagged and brittle with sharp edges that cut into her upper lip which took about 2 weeks to heal. Unfortunately the return window had closed.

Busy bone
Color: Blue T-Bone, Size: 1 Count, Color: Blue T-Bone, Size: 1 Count
My dog loves these!! Great busy bone! And they can hold it with her paws really well. It does kill your foot if you step on it barefoot in the middle of the night. This is a picture of the bone after 7months.
