That is because the lower the temperature the less humidity is necessary to actually feel it and for it to bother you. 75% at 10c is not that bothersome since it is not that high of an air humidity, while 75% at 30c can even damage your health due to heat.
Explanation:
Humidity is outlined because of the quantity of wet in the air. If you're standing within the restroom once a hot shower and may see the steam hanging within the air, or if you're outside once an important rain, then you're in a part of high humidness. If you're standing within the middle of a desert that has not seen rain for 2 months, or if you're respiratory air out of a breathing machine tank, then you're experiencing low humidness.
