Earth and Environmental Science (Decline in health comfort with masks)
“…The experimental results show that wearing a mask significantly reduces the person's thermal comfort level and air quality perception, leads to a decline in health comfort level. As can be seen from figure 3, the voting value of the thermal and wet sensation increases after wearing the mask. This is mainly because of the space behind the mask is blocked, and nasal airflow will become hot on the sides of the cheek, and makes people feel more hot and humid.”
