Thank you for all of your hard work Aunt Scripty <3 My characters are part of a city that has lived underground for security reasons for a 100 years or so. My question is, if a group of 20 or so of them head out into the sunlight for the first time, what range of impacts could it have on their health? They have a physician among them taking notes and comparing it to their condition back underground
Hey there nonny! This is an interesting question, and while it’s an unusual one for me, I’m going to give it a go.
First, I don’t think it’s possible for them to have survived completely underground without sunlight of any kind unless all they’re eating is fish. You didn’t mention whether this is future, present, or past, so I’m going with present and I apologize if I got the time frame wrong.
What Are They Like Underground?
Here’s what the what: remember that these humans need to eat, and mostly what they’ll be eating is plants, and plants need so much sunlight to grow, which means either a) they have at least one area where they get and use sunlight – I’m thinking a big hole in the roof of one area (I’m imagining caves, sorry if this is wrong) and arable soil underneath, b) they only eat what they brought down there with them, bunker style, or c) they are relying on fish from an underground river, which may or may not work and may or may not be enough to sustain your population. Humans can survive almost entirely on fish, but it’s not exactly a pleasant survival to eat the same thing over and over and over again – but I’m sure all of this is stuff that you’ve thought through and already solved.
One of the big questions is Vitamin D. The body uses sunlight to produce Vitamin D from its base components. It’s not found in the human diet so much except in products that we’ve fortified, such as milk, and vitD deficiency is common even in our above-ground world for those of us (like me!) who work indoors.
One thing to look at is therefore a disease called Rickets, in which the bones fail to mineralize properly due to VitD deficiency, and the bones are soft, easy to break, and often deformed. Asthma is another health problem associated with VitD deficiency, especially in children, and VitD deficiency has been implicated in hypertension, heart disease, high cholesterol, and cancer.
Fish does contain a certain amount of vitamin D, but not an enormous quantity, as do egg yolks, so if your characters are eating eggs and fish they might have lesser forms of the disease.
Also, remember that these people will have paler skin regardless of their skin color; that is, even those with heavily pigmented skin won’t tan in the caves because they won’t have sunlight, so they’ll default to only what their genes have given them. Once outside they’ll start to tan – even those with dark skin – and get a bit darker.
Let’s not forget scurvy as another form of malnutrition. Scurvy is Vitamin C deficiency taken to an extreme, which causes weakness, lethargy, sore limbs, bleeding gums, and a general tendency towards bleeding and difficulty stopping bleeding. Scurvy is a big problem that is fairly easily solved; citrus fruits are a natural source, and ascorbic acid, a common preservative, is just another name for Vitamin C. If your characters are eating large amounts of preserved food, and that food is preserved with ascorbic acid, it’s likely that they won’t have horrendous vitamin C deficiencies, especially if they’re eating canned citrus on the regular.
In short, your characters might be fairly sick from living the lifestyle that they’re living, depending on what they’re eating and how much.
Here Comes the Sun (doo-do-doo-do!)
And I say, it’s alright…
There are a lot of impacts seeing the sun for the first time could have on their physical welfare, and it’s worth taking a look at all of them.
For one, their eyes are going to have to take some time adjusting to the brightness. I don’t think there would be any actual damage per se, but headaches and vision troubles could be a problem in the first few days.
Myopia might be A Thing, since, having never been outside, these characters may never have had to use their distance vision; they may be near-sighted. They may have trouble focusing on things at a distance.
For another, VitD deficiency is going to get a lot better because, well, humans make Vitamin D in the presence of sunlight.
A whole mess of them are going to get sunburns, including those with dark skin, and depending on the time of year and the latitude at which the characters’s underground home was made, they might wind up with blisters or sun poisoning. Heat exhaustion during the summer is going to be A Thing.
If it’s winter, there’s actually a different problem, which is – the temperature underground tends to be remarkably resistant to changes in temperature above the surface, so their cave / bunker might be a very consistent temperature, and they might not be prepared for winter up above. Frostbite, frostnip, hypothermia might all be common, since temperatures underground tend to be in the 50s-60s(F), where temperatures above can be…. extremely cold, by comparison.
Next question: what do they eat when they’re Above? Are they eating the flora? is the flora safe to eat? Consider what they might decide to eat, and look at the health consequences of that. Blueberries might be fine, and if they hunt, hunting animals might be fine, but if they went underground to escape, say, radioactivity, and they start eating radioactive plants, they miiiiight wind up with radiation poisoning. Also, those with genetic allergies might discover those allergies Up Above that might not have bothered them in the cave, though most allergies will take time to develop.
Lastly, where are they getting their water? Is their water safe to drink? If they’re downstream of a place with poor sanitation, cholera could definitely become a problem, as could various forms of worms; if they’re smart they’ll have some form of purification system (iodine tablets, UV purifiers, boiling) but if not, they may get sick from the water.
In short, the sunlight itself isn’t really that big of an issue beyond sunburns (which no one will know how to prevent), but there are a lot of nutritional issues that you might want to consider when building your story and your world.
I hope this has been useful and I’ll gladly see you later. Bye bye!
Today I remembered I have a Tarnma fairy au and I decided to add a lot to that
Shockwave’s a huge deer fairy thing that grows dangerous and rare plants out in the middle of a HUGE forest. He researches and tries to cross breed them
Blurr’s a tiny speedy flower fairy that ends up getting caught up in Shockwave’s gardening experiments (and Shockwave too lmfao)((he decorates Shockwave’s antlers with flowers when he’s bored))
Bumblebee’s an easy going flower fairy that lives in a big sunflower field by himself that he planted with a bunch of friends/family a long while back, but since then they’ve all moved on (or died) and he’s the only one left tending to the field
Starscream is a bird shifter that got kicked out of Megatron’s clan for being an Ass so he tries to form his own out of spite and p much gets stuck with Bumblebee due to his reputation scaring away most fairies and Starscream’s own stubbornness and pettiness (not that he minds in the end)
Not shown but still important:
- Megatron falling for Optimus, a human that’s excessively kind to plants
- Soundwave’s a fairy that rides on the back of a large cat always followed by 2 birds that sings to lure humans into the forest (Rumble and Frenzy are 2 lil shits that just break into houses to steal tiny things tho, no class compared to their dad)
Hello, hope you started well the weekend. Here it’s raining non stop since 2 days, temperature dropped to 10 degrees / 50 F, not surprised because it snowed on the Säntis mountain, when there it’s cold, we feel it.
I prepared the newspapers for the recycling, Ginger was standing and looking what I was doing, then he saw the cord, he jumped and grabbed it, lol.
Have a lovely weekend. Thanks for the comments, flying hearts, reblogs.
Check out this cool beetle I found hiding under a Virginia creeper leaf! It’s a leaf beetle, Calligrapha californica to be exact. It was the one bright spot in an otherwise dreary, dreary day. Cannot wait for temperatures to heat up next week, this bleak 50′F grayness is not good for insect activity…
It's currently over 97 F here and 50% humidity where I'm at right now. Could I request a fic with the RFA members dealing with the heat? I'm partial to beach visits myself when I can, but sometimes you've just got to dump a bucket of ice into the bathtub and wait it out ¯\_(ツ)_/¯
To those that have sent in or want to send in fic prompt requests, don’t worry, I haven’t quit doing them! I’m going to keep my posts even so it isn’t all headcanons or all fics!
The biggest baby you’ve ever seen
Has to pee every fifteen minutes because all he does is DRINK GALLONS AND GALLONS OF WATER
Has every single fan in the house on
Won’t eat or drink anything hot even if you try and shove it down his throat
Lots of “uuugggghhhhs” and “this sucks” every two seconds because for some reason he thinks that someone’s gonna hear his desperate pleas and turn South Korea’s heat down just for lil ol Kim Yoosung
The Beach Guy
It’s also an excuse to keep his shirt off in public
Zen can never tan for some reason??? He just can’t, it never works
Drinks shit tons of water like Yoosung except he spaces it out properly so his bladder isn’t ready to burst
Really cranky at rehearsals because sometimes it’s hotter inside than it is outside and it gives..him..the worst…headaches..
He hates people being really close to him during the heat *it’s usually fans that run up to him* because he feels all disgusting and sweaty and ohgod girls and guys please let me g o
It’s nice and cool in the office, so she likes that
If it’s that hot outside, then she avoids going outside as much as she can
Avoidance is the solution to all problems
Usually she has hot coffee buuuuut now she’ll switch to iced coffee
Hates complainers because IT MAKES HER MORE CRANKY ABOUT THE HEAT “WE ALL HATE IT OKAY, DO YOUR WORK WE’RE ALL SAD HERE”
She is easily worn out in the heat but more importantly her biggest summer enemy is underboob sweat, okay, it makes her wanna carry baby wipes with her everywhere she goes, she despises it
Doesn’t get what all the complaining is about??? Just turn the AC on???
Jumin isn’t necessarily a fan of the heat, but he doesn’t see a need to be so…bothered by it
The only thing that annoys him is that he can get sort of itchy; his skin gets irritated depending on how hot it is
It also makes it harder for him to think
But he’s not outside a lot and the building is air conditioned??? So Mr. Han is hardly even fazed
more complain-y than Yoosung with this yet I can’t help but relate
That ice bath?? He’s done it.
He likes to stand in front of the fridge with it’s door wide open and it pisses Vanderwood off to the point of no return
“You’re WASTING ELECTRICITY!!!!”
Seven does not care because he cannot and will not stand the heat, he will have the AC on as well as every single fan, whether it be the little handheld fans, ceiling fans, plug-in fans, it doesn’t matter
So Vanderwood wanders around the house in a jacket or two because he’s freezing his secret agent balls off
