Ever since my living room double-pane window got foggy, I've noticed that I feel very uncomfortable/sick when it is a very sunny day (similar to the way I feel when I've been out for too long in the sun on a super hot summer day).
If I close my blackout curtains (which aren't the highest quality) I still feel pretty sick. They don't seem to be of much help.
If I move to another room (that faces the opposite direction of where the sun is shining) I feel better after a few minutes. For example, if this were my house, my movement would be from the Bed1 to the Lounge (in my house Bed1 is my living room and Lounge is my kitchen).
After the sun is set or is fairly low, or when it is on the other side of the house in the morning, the room is comfortable and I have no issues there.
Additionally, this problem used to only happen in the summer, but since my backyard neighbour cut a tree on his side (which used to partially block the sun coming in my window) it has been happening in the fall too. Even with the temperatures going down right now (fall), I am still feeling sick when the afternoon sun is at its strongest against the window.
The wall right in front of the window and the one parallel to it are mainly blank white walls (we haven't had the time or $ to decorate yet), which I think could be part of the problem.
The window is quite big, about 3 ft X 4 ft. And I would say 75% of it is now constantly (24/7 year-round) foggy or filled with water drops (we've asked the landlord to replace the window, but they are taking their sweet time).
I work from home, so I spend practically the whole day in this room. I don't feel uncomfortable immediately after the sun appears on the west side of the house (in the afternoon), but after a couple of hours (around 3 PM, when it is more or less at its strongest against the window) it starts happening.
From the answers in this related question and this one, it seems possible that the UV rays might be getting amplified by the water drops + the double panel + the white walls. Am I correct in making these assumptions? Or am I just going crazy?
Additionally, is there a way for me to objectively measure the UV index inside a room? (preferably using a free app on my phone, or some other free/cheap method)
Any help or ideas are appreciated!
