Based on your symptoms (fever of 38 degrees, headache, sore throat, chills) and the context of a very warm indoor environment followed by exposure to cold, it sounds like you may have caught a common cold or possibly the flu. The rapid temperature change could have weakened your immune system.

Since I'm not a medical professional, I can't give a diagnosis. It would be best to consult with a doctor or other qualified healthcare provider for an accurate assessment and advice on treatment. They can properly evaluate your condition and recommend the best course of action.
