The body is a complex system that functions smoothly in unison, so we don’t usually take the time to consider what is happening behind the scenes. Until we start noticing something out of the ordinary about it. Then it becomes hard to remain calm, and we begin to seek information or reassurance from others that the strange things we’re experiencing have a perfectly normal explanation. 
The people in this thread did exactly that. They shared the weird quirks their body has that they don’t fully understand, in hopes they find others like them or even ways to explain them. To read them for yourself, all you have to do is scroll down!

Apparently I'm developing Musical Ear Syndrome, or musical tinnitus. When its quiet and I'm trying to sleep I'll hear what sounds like a radio playing quietly in another room. It seems to be a form of tinnitus that instead of hearing a ringing or buzzing, your brain generates musical sounds as the interpretation instead. It freaks me out sometimes.

moon_buzz:

I can't express how happy I was to read this, thought I was insane. Alone at night I can totally hear rhythmic music in the silence, if i lift my head to get a better listen then it goes away. head back on pillow it goes again. I first thought it was neighbors having a party but it happens too often, and typically is the same beat.

Sometimes I just shiver for a split second for no reason even when it’s piping hot outside.

mostly_elbows:

I really thought this happened to everyone because I've always done it, and growing up we just said, "I got a chill." It was as normal as sneezing. In adulthood, people look at me crazy anytime it happens. I think they're crazy for having NEVER experienced it. Like how?

Require me to RUN RIGHT NOW to the toilet as soon as I get somewhere near my house. Listen, Bladder, I get it, you're full. I'm on my way. Just take a chill for a few more seconds for f**k's sake! You wouldn't even be pulling these shenanigans if the eyeballs hadn't told you where you are!

theseedbeader:

Oh the misery of Latchkey Incontinence. I get this a lot. I usually make sure I empty my bladder right before I head home from work or running errands. If I have a full bladder when I get to my door, it’s an instant emergency and my body suddenly stops obeying me.

Everyone experiences unusual bodily functions to some extent, and many of them are completely normal. It’s simply how our bodies function, which means that we don’t have much control over it. Medical experts online have been discussing and helping people understand more about them, so they know that experiencing strange symptoms is very common and that, for the most part, they’re nothing to worry about. 

Something that many are concerned about is hair loss. However, shedding is an ordinary part of having hair on our heads. “Most of us lose up to 100 hairs from our scalp every day, which is normal,” says family physician Jennifer Caudle. “About 80 million men and women in the United States have hereditary hair loss.

“But, it’s possible to lose hair if you have certain medical conditions or take certain medicines,” she noted. Excessive hair loss can also be caused by stress or malnutrition, weight changes, hormonal imbalances, menopause, thyroid issues, or iron deficiency. So if you start noticing extreme hair loss, you might want to see your doctor.

The sudden jerk you feel when falling asleep is also very common and has a totally sensible explanation. It’s called a ‘hypnic jerk’ or ‘sleep start,’ which can be accompanied by the feeling of falling. Up to 70% of people sometimes have this symptom. Even though scientists can’t really explain why they happen, they reassure us that they’re nothing to worry about, as they’re likely caused by our body releasing tension. 

“We often hold tension in our muscles from stress during the day,” sleep expert Dr. Richard Shane says. “When we begin to relax on the way to sleep, sometimes that tension releases as a jerk.”

I get itchy when I exercise. its unbearable and apparently I'm not the only one. I manage.

Another strange body behavior that is totally normal is goosebumps—the tiny bumps that appear on our skin around the hair follicles.

“Goosebumps happen involuntarily and are caused when a small muscle at the bottom of each hair follicle contracts, causing the hair to stand up. In animals this may actually form a layer of insulation,” Dr. Caudle says.

“They can occur due to cold air or also happen when we experience strong emotions such as shock, fear, anxiety, or even being inspired.”

I can hear electricity. Like clearly. I’ll know if something is plugged in or running - like if I get into bed in the dark and don’t hear ringing - I know my charger isn’t plugged in.

Just now for eg, I heard an annoying ringing sound and realised I left my in slab heating on downstairs because I can somehow hear power being sent to whatever it is that runs it lol.

I produce a truly astonishing amount of ear wax. Have to clean them out several times a day. Sometimes when I get hot I can feel it dripping slowly and it drives me insane.

thatcliquekandy:

I sort of have the same issue. My ears get stopped up so often now that I physically have to get them cleaned professionally! I like had to go to the hospital bc I couldn’t hear! Once nothing helped and my ear started bleeding. Found out my husband ruptured my ear drum when cleaning my ear… AND I had an ear infection too on top of that at the time. I. Was. Miserable. Thank weeks later I had a seizure. My body clearly hates me.

Lastly, the intrusive thoughts that some people have, like shouting in a silent room or swerving a car, are also generally considered to be normal, even though they appear very strange.

“Intrusive thoughts are unwanted thoughts or images that seem to pop into our minds against our wishes and often focus on the thing that would be most inappropriate in a setting or the thing that we most fear,” says Dr. Hannah Reese, an assistant professor of psychology at Bowdoin College. “For this reason, they are usually upsetting or distressing to the person having the thought.”

“When we experience an intrusive thought, it is best to recognize it for what it is, not take it seriously, and let it fade away on its own,” Dr. Reese says. Because the moment you try not to think about it, they can start appearing more frequently.

The veins in my fingers randomly explode. All of a sudden I’ll feel a super sharp pain in one finger (like it’s just been hit with a hammer or something) and there will be a dark blue spot under the skin where the blood is starting to pool out. If I can grab an ice cube immediately it usually won’t swell too bad. If I don’t have access to ice then the whole finger swells up a bit before it stops

It must be genetic because my mom has the same thing. We found on the Internet that there is a name for it, Achenbach syndrome, but no one knows what causes it or how to prevent it.

I have a milk duct thingy above my collarbone. Never knew about it until it popped up during my first pregnancy, and then my doctor checked it out and it turned out to be a tiny extra pocket for milk almost in my neck.

I leak from my ears when I cry.

I mentioned it to an ENT once, and he thought that maybe there was some odd connection from my tear ducts or sinuses that was causing it and that it might explain why I had chronic sinus/ear infections as a kid.

FluffySquiddy:

There is a connections between nose and ears, it's called the eustachian tune. I don't think it is tears passing through your ears, but rather nose mucus. As a kid I had chronic otitis and my doctor would warn me against sniffing.

Depending on where I touch or scratch on my arms and hands, I can feel the sensation in other parts of my body. Oh, and my nervous system just likes to go haywire and keep me on my toes every once in a while. Like, "Oh, hey. I heard that you have to make a phone call, or do some other normally mundane task you've done a thousand times....but now it's scary! I hope you like that feeling where you're about to fall backwards in a chair, for hours on end!".
