As we get older, we get used to hearing a lot of unusual sounds from our bodies.
They pop, click, and gurgle whenever we have to move around, which can be a little embarrassing and annoying.
But with so many noises, it can be hard to sort out the dangerous ones from the simply annoying.
Here are 12 of the most common noises, and what to do if you hear them.
1. Popping joints
If it sounds like you're making popcorn when you stand up, there's nothing to worry about - you're just getting old. As long as your popping joint doesn't hurt, it's perfectly healthy.
Our joints are full of a cushioning liquid called Synovial fluid. When we move, air bubbles in the fluid pop.
The noise is especially common in the neck or shoulder, because of our bone structure.
The noise is also the same one you hear when you "crack" your knuckles. And yes, that habit is harmless too.
2. A Rumbling Stomach
We always say this means that you're hungry, but that's only half right.
The growling noise is caused when air and fluids are pushed out your digestive tract. The same movement just triggers when we're feeling hungry.
3. "Windy" Ears
When you lay your head down on a pillow, you can probably hear a "whooshing" sound. This is the sound of blood pumping through the veins and arteries of your ear.
Now, if you notice the same sound when you're sitting or standing, you may have a problem. It could be a sign of an ear infection, or allergies, so see a doctor.
4. Snorting And Gasping In Your Sleep
Like snoring, these noisy outbursts could be caused by sleep apnea, or when your airway collapses as you're lying down.
If you feel tired on days after your partner complains about the noise, it might be time to see a sleep specialist.
