Am I overthinking? I did not have ironing board in my doorm so I used my bed as an ironing board. I didn't realize that the bed sheet was made of a synthetic fibre. The sheet was burnt and the burnt sheet made a nasty smell... doesn't seem like a good smell.... I ended up breathing in a lot of that nasty gas. I changed my bed sheet but parts of my bed is slightly browned and had light odour of the burnt sysnthetic fibre. Should I change the mattress? Would my bed become a health hazard 😓
