A super fun pop science book about our 32(yes 32) senses.
Typically we are taught the 5 main senses, but in reality our bodies are collecting sensory data on 32 fronts. This book has it all; depth in terms of scientific knowledge, personal stories of sensory savants, interesting facts about how our senses developed and examples of how we can improve our own sensory experience.
A huge takeaway for me from this book is the range of experience that everyone has in terms of the sensory experience that hits their brain. This can lead to more empathy and desire for understanding. If one person demands the room is too cold, and the other is unbothered - there is no need to discover who is right- both people are experiencing the same temperature of the room differently. This can go for so many senses such as noise levels, tastes, sense of direction etc. It reiterates the need for acceptance of others - not conformity.
The main categories of these senses are:
-Sight
-Hearing
-Smell
-Taste
-Touch
-Pain
-Temperature
-Proprioception (body mapping - knowing where our bodies are in space, limb location)
-Orientation ( Vertical motion, horizontal movement etc)
-Interoception (innersensing - heart beat, blood pressure, Blood O2, Blood CO2 etc)
-Gut Feelings ( how much water we have, stomach fullness, etc)
Below I have listed some fun ways from the book to improve our own senses, experiments to see how our perceptions of our senses can change how we view ourselves, and some incredible stories or facts about our senses. Writing them out helps me remember them, but feel free to take a peak yourself, or better yet, grab the book and read it for yourself.
Sonar Vision - blind man rides a bicycle
Using clicks from his tongue Daniel Kish gets feedback from his environment, much like a bat, in order to sense his surroundings. This allows him to walk and even ride a bicycle.
*smelling fishy* is a metaphor used for something not convincing in over 20 languages.
Something tasting 'hot' is due to the fact that peppers have capsaicin which activate the same receptors that tell us that the temperature is warm. It is tricking us to thing that the temperature has increased - and our body responds accordingly.
Magic Shoes - what we hear can influence our perception of ourselves
Wear shoes with a microphone which is played into your ears so you hear your footsteps. Filter the noise so that we are only hearing higher frequencies. This makes the wearer feel physically lighter, people wearing these shoes report increased happiness.
Mapping which way is North.
When you go new places try to guess which way is north from where you are. Then check. Over time you will start to pick up clues from your surroundings and be more aware of your sense of direction.
Sensing your own heart beat.
Set timer for a minute. try to sense and count your heart beats internally (not using your hand) Then try again with using your hand to sense it. Over a long duration, having a better sense of your own heart rate can help lower anxiety.
These are just some fun things I learned and took away from a really cool book!
