COPING WITH THE COLD
The snowshoe hare has its own built-in snowshoes i.e. enlarged hind feet, which helps when crossing soft snow. Its smaller ears prevent heat loss.
Polar bears keep warm with their specialised coats – hollow hairs, which traps and warms air, and a thick undercoat that keeps it warm. The top coat can even keep them dry when swimming.
Some insects enter a state called torpor. They find a good hiding spot and chemicals are released into their body fluids to prevent them from freezing, similar to anti-freeze in the radiator of a car.
In humans fat is important to keep you warm!
There are two types of fat in the human body:
- White fat used for energy metabolism, heat insulation and mechanical cushioning.
- Brown fat is found mostly in new-born babies, between the shoulders, and is important for thermogenesis (making heat).
Fat cells do not generate after puberty – the number of fats cells remains the same but get bigger, the same applies when loosing weight
(you only get more cells if you gain a large amount quickly).
…YOUR HIP BONE’S CONNECTED TO YOUR BACK BONE…
- We actually do have joints that can’t move, called fixed joints. The joints in our skull are fixed joints.
- We have more than 230 flexible and semi-flexible joints in our body.
- Cartilage protects the bone surface in joints and have a shiny, cloudy-white appearance.
- Early in development, cartilage makes up most of our skeletons.
- Cartilage is a tough but flexible tissue that has two components: water and matrix.
- Cartilage is up to 8 times more slippery than ice and with the ability to soak up and push out water as easily as a sponge, it’s perfect for joints.
Cartilage does 2 jobs in the joint: (1) provides ideal shock-absorbing capacity and (2) lubricates the joint to give the joint seamless motion.
TASTE – IT IS A SCIENCE…!
Did you know…
- There are thousands of tiny taste buds on your tongue and the roof of your mouth.
- Every person’s taste differs – and it changes as you get older.
- Sensitivity of the taste buds decreases as you get older.
- Taste disorders can occur with for example smoking, use of certain medication and with certain diseases.
- Taste buds are sensory organs and flavours are created when a substance in the mouth reacts chemically with the receptors in your mouth – taste buds.
- Different regions of the tongue is more sensitive towards different tastes than other (See picture).
Taste is a perception – one person may perceive a taste as pleasant while other may experience the same taste as an aversion…
MATTERS OF THE HEART
- In your lifetime your heart will beat 2.5 billion times.
- Your system of blood vessels is over 96 500 km long and would stretch around the world more than twice!
- The pressure created in the heart during a heartbeat is enough to squirt blood a distance of almost a meter.
- Your heart’s pumping action allows your blood to circulate through your entire body in about 20 seconds.
Take good care of it! The risk of heart disease for inactive people is double that of people who get regular exercise. So get at least 30min of moderate exercise on most days of the week and eat a heart healthy diet.
To give your heart even more love and care, you can take a supplement like Nativa Cardio Complex.
