Despite temperatures in the province dropping to as low as 10 degree Celsius at night-time, Noppakhun Saenyod, 52, had been sleeping wearing only shorts, a white singlet and without any blanket to cover him.
As there were no signs of a struggle and no wounds on his body, police suspect that he died of heart failure.
Reports said that the temperature in Chiang Rai dropped to 13.1 degrees this morning. However, the temperature can fall even lower during the night, especially in mountainous areas.
