4. Missing Glacier National Park Hiker
I went to Glacier this past year, and it’s still near and dear to my heart. I’ve been tracking this missing hiker news since yesterday.
Sad stuff. You just can’t safely hike alone out there.
Glacier is Pretty. And Scary as Fuck.
5. What is ‘knuckle cracking’
I’ve wondered about this my whole life. If you’re curious:
Joints are the meeting points of two separate bones, held together and in place by connective tissues and ligaments. All of the joints in our bodies are surrounded by synovial fluid, a thick, clear liquid. When you stretch or bend your finger to pop the knuckle, you’re causing the bones of the joint to pull apart. As they do, the connective tissue capsule that surrounds the joint is stretched. By stretching this capsule, you increase its volume. And as we know from chemistry class, with an increase in volume comes a decrease in pressure. So as the pressure of the synovial fluid drops, gases dissolved in the fluid become less soluble, forming bubbles through a process called cavitation. When the joint is stretched far enough, the pressure in the capsule drops so low that these bubbles burst, producing the pop that we associate with knuckle cracking.
It takes about 25 to 30 minutes for the gas to redissolve into the joint fluid. During this period of time, your knuckles won’t crack. Once the gas is redissolved, cavitation is once again possible, and you can start popping your knuckles again.
6. Why do legs fall asleep?
While I’m solving the world’s mysteries…
When you apply this pressure for a prolonged period of time, you actually cut off communication from your brain to parts of your body. The pressure squeezes nerve pathways so that the nerves can’t transmit electrochemical impulses properly. Nerve impulses carry sensation information from nerve endings in the body to the brain, as well as instructions from the brain to the parts of the body. When you interfere with this transfer by squeezing the nerve pathways, you don’t have full feeling in that body part, and your brain has trouble telling the body part what to do.
This pressure can also squeeze arteries, stopping them from carrying nutrients to body cells. Without these nutrients, the nerve cells may behave abnormally, which can further interfere with communicating bodily sensations.
Due to both these factors, the information transmitted from the body part becomes somewhat jumbled, and the brain receives strange messages. Some nerve cells don’t transmit any information and others start sending impulses erratically. This causes you to feel a strange tingling sensation, which actually serves an important function. Your foot falling asleep for 10 minutes doesn’t pose any health threat, but if you were to cut off circulation for an extended period of time — several hours — you could suffer serious nerve damage. The initial tingling sensation tells you that you might want to readjust your position.
