Even when I worked in an office, I got out during the day and had some sun. That was only minutes but it mattered a lot for my soul. I need sunlight. My energy and mood drastically dropped without sunlight for some days and my energy never was high anyway. It changed on carnivore-ish (well I stray all the time, it surely will be better when I will be able to stick to it), my energy is still low but I don’t feel utterly miserable on a gloomy day even if it’s the 3rd in raw. Rain is better but when it’s just gloomy without rain and the house is darkish all day due to it… That’s not nice.
And there is the weekend too, I used to go out a lot. Except in summer, of course but summer is so very very sunny that even then, I still got some sunlight.
Be careful. My mom had very white skin. When she went to the beach after working inside all the time, she got burnt. When she retired and started to work a lot in the garden, she got used to it and got a strong tan during summer without any burns. She should have use some protection, though, I suppose… But she didn’t.
Use strong sun milk(?) too (I am not knowledgeable, I just know I have that and I should use but I forget so I never use anything. sometimes I remember it when I go for a 40km long bicycle tour in summer, fortunately. I easily burn too when I swap to sleeveless shirts in summer and my white shoulders suddenly get a brutal sunlight exposure. a short summer walk is fine).
I didn’t mention but I typically use sleeveless shirts in summer as my usual short sleeve t-shirts are too warm. Some of them is better, they have shorter sleeves. My normal t-shirts cover my whole upper arms.
I think I hinted that I actually expose part of my arms in winter if the weather is nice (it’s not so rare. I don’t need a high temperature when walking in the sunshine. I choose the frequent sunny times for my winter walks if possible as I love sunshine expecially if it’s not summer).
I am definitely glad I don’t live in less sunny parts of the world. It would be better to have warmer winters and colder summers, higher mountains and sea but we can’t have everything. It’s not that bad here. Lots of sun, frequent rain. I lived in a place where summer meant 2 months without rain. And we had a big vegetable garden with some very needy plants… The soil was great though and there was very much sunlight so they were okay when we watered them 2-3 hours every day… And did all the other garden work. It wasn’t worth it IMO but it wasn’t my decision.
Oh and I didn’t mention sometimes I am on the terrace outside, reading, playing with the cats, sweeping or whatever. I get some sun there too. But I actually prefer 1-2 hours walks, I just don’t always do them and part of it is in shadow. A bigger part in summer but I don’t worry about my sun exposure in summer, I may avoid the sunlight as much as it’s comfortably possible and I still get much enough. It’s summer, after all, almost always sunny during the day 
Did I say I never take supplements (except if I get cramps but I don’t do that anywhere close to carnivore with enough meat, I take one magnesium pill and forget about it for weeks)? I have no idea if I have deficiency of anything (my magnesium is surely low as a bit wrong diet for a little while and I get my magnesium-related cramps), one day I will go and figure it out.
