I have heater very close to me and it feels like my skin is burning and my skin goes dry. is it dangerous if have done this for around 5 months but regularly throughout day. is it only small risk for skin cancer?

Exposure to prolonged heat can cause reticulated, erythematous or hyper pigmented dermatosis called erythema ab igne. Chronic and low level of infrared radiation causes it, later on squamous cells and Merckle cell carcinoma can develop. Low. Level light therapy LLLT or PBM helps in rapid healing of wounds and for intrainflammatory purposes. In short, if changes of erythema ab igne, avoid heat.

Doubt any relationship to cancer Still the best approach is to keep the room/home comfortable as you need A warm clothing or a blanket may be a better choice
