it’s a rainy day
rainy days are so dreary. more so for some than others but i think most people would agree that rainy days are not fun. i hate them mostly because i don’t like getting wet in clothes. there’s just something about having the formerly loose material sucked skin tight to my body, restricting movement, and making me heavier.
but it also makes people sleepy. i think that most people would agree that when it rains, they want to be lazy and just take naps or veg all day. i have a theory as to why this is so. the most common reason given to this phenomenon is the sound of the rain. when you are in a building and it is raining outside, most of the time you can hear the rain pounding on the roof. this sound just seems to make people not get out of bed because it instantly drugs them into sleep again. well i would remind you about pavlov’s dogs.
in case you’re not familiar with the experiment, this guy named pavlov decided to do an experiment with some of his dogs (hence the name). what he believed was that animals’ (which includes us) brains are triggered by environmental stimuli. to test this, he put some dogs in a room and would only feed them a certain way. before feeding them he would ring a bell. and that’s all of the important stuff. over time though, the dogs began to associate the ringing of the bell to them getting to eat. it got to the point that when he rang the bell, the dogs would begin to salivate even there was no food in the room at all.
we’ll get back to that in a second. my theory about us getting sleepy when it rains has to do with the pressure of the atmosphere. i might need to give you a little background on atmospheric pressure though. air has weight. it is minimal but when you have an atmosphere full of it, the numbers begin to add up. and think about it, above you is about 50 miles of air. gravity affects all things with mass and since air is made up of lots of tiny particles and each of those have mass, the air above you has mass and is being pulled down by earth’s gravitational pull. this amounts to atmospheric pressure. the farther you get away from earth, the less air there is because the majority of the air is being pulled down towards the surface.
another quick thing. air will fill up a space it is in but it is easily compressed as well. think of a balloon. the reason it keeps a uniform shape is that the air you are putting inside of it is trying to space itself out prefectly and is putting uniform pressure on the lining of the balloon. also, think of a room. if you put a little bit of air in there, you will have difficulty breathing because the air will be spread out and you will not be getting the oxygen you need. by puttin gmore air in (which will also increase the pressure in the room) you will be able to get the oxygen you need to breathe. this is because the oxygen is more condensed to to the hightened pressure.
so back to the rainy day. since it is caused by a low pressure front, i conclude that we get sleepy because there is less oxygen per cubic foot around us than we are used to. not getting the oxygen you need causes your body to get “sleepy”.
and pavlov’s dogs. i think that we have been conditionally trained that when we hear the sound of rain, our brains automatically associate it with being sleepy.
i think i think too much. i’m goingto kill some brain cells with a video game.
