If you cover the blanket at this time, the heat dissipation will be reduced even more, but the increase in body temperature will be more obvious and will aggravate the symptoms of fever. This is why you should not cover the blanket with fever. At this time, you should unpack your clothes and try to wear thin clothes, or drink more water to promote the excretion of urine and take away excess heat from your body.
