When we run too fast or laugh too hard, how come we sometimes get stitches?

i dont know all the sciency stuff but basically the "stitch" is the build up of lactic acid when your cells cant get enough oxygen to them quick enough

It's because the muscles around your chest contract and tense when you're hurt emotionmally cos you're body thinks it's a physical threat and is getting ready to either fight or run

It is not funny that the person got hurt it is funny how they got hurt. Many people's first reaction to accidents is to laugh it is not that it is funny but it is that laughter can sometimes make something serious a little lighter. Don't you laugh when you fall down or make a fool of yourself.

I won't pretend to know the biological and/or psychological mechanisms taking place that is conducive to this. It's just a spontaneous (laugh) reaction that most humans have in response to the stimulus of hearing something funny. We have just marvelously been created and "wired" up that way.\nA word of caution --- what you may interpret as "hearing something funny" is purely subjective. What you may hear and interpret as being funny may not always be perceived the same way to other individuals --- hence, beware that hearing a "funny" joke/experience could potentially become an embarassing situation ... 'nough said.

pulls generally knot up while tears tend to knot up and bleed under the skin,  turning into a very nasty and obvioud bruise. It takes a tear much longer to heal and more stretching to loosen it up before strenuous exercise.

when you exercise you kind of like ripping your muscles. when they get repaired on their own they become bigger and stronger. i didnt give you an answer from medical point of view, but you ask any doctor and they tell you this, but in a better description. thanks to you.

thats a really good question. i was curious myself. i couldn't find too many "actual" answers. no one really knows why. i did find the following article that explained it (sort of).\n\nif you don't feel like reading it. in summary...laughing is a built-in reflex when tickled and we dont' laugh when we tickle ourselves because we know its coming. Our brain needs tension and surprise for us to really be tickled. A part of the brain says to the other part of the brain "It's just you. Don't get excited"\n\nhope that helps

it happens when a joke contestes your mind about a belief you have and when you think about it, you notice it is silly and than laugh at it.\n\nthe sound comes from when you breath and happen to do it really fast (mind you, other countries may say other expressions when their laughing. saying hahaha is purely a western things)

Laughing is good.  My partner of 10 years constantly has me in stitches.  It's the BEST.  If you laugh together, it can only be good!

Maybe blood clots. Or something just as serious. Maybe just working out too much or over use? See your doc if it keeps up.

let your body heal, don't do any exercise until your doctor gives you the okay.  If you work out and rip a suture you can put yourself in a world of pain and trouble.  Open wounds get infected real fast, they can lead to infection and depending on what was operated on you could permanently damage muscle.

use your thumb and the rest of you fingers and squeeze moderately where your kidney should be, and then push upward a little bid. Stitches are usually caused when the ligaments holding your liver which are connected to the bottom of your lungs in place are stretched out too much becuase of your breathing with your lungs going up and down and downward force everytime you put your foot down, so you squeeze that part to relieve the stress on that ligament, and it would be best to stop and take big slow breaths.

sounds like you've pulled or strained a muscle

It wasnt too funny when it happened to me.  I had just had my hysterectomy and THOUGHT I had to pass gas.  WRONG!  Went right on myself.  I was still in the hospital at the time doing my laps and ran as best I could all the way back to my room passing bathrooms all along the way for some unknown reason.  Its funny now that I look back at it but it sure wasnt when it was happening.

It happens when you are asking more to your body than what it is used to give.  You gain resistance little by little.  For example if your tops is running 1 mile, if you go to the track next time and you force yourself to run two, you will probably get sick and throw up. You need to raise your "bar" little by little, so your muscles and respiration have time to adapt and respond with less stress.

if you are having chest problems, you are probably doing too much too fast.
