Yes, being under a blanket can raise your body temperature. Blankets trap the heat naturally radiated by your body, creating an insulating microclimate. This external warming can increase your skin temperature, cause sweating, and even temporarily raise your core temperature by 1 to 3 ∘C ( 1.8 to 5.4 ∘F).
