How much indoor humidity is normal?

Generally, it is normal to control the indoor humidity between 30% and 80%.

In winter, the temperature is 18 to 25℃ and the relative humidity is 30% to 80%. In summer, the temperature is 23 to 28℃ and the relative humidity is 30% to 60%. More than 95% people feel comfortable in this range. In an air-conditioned room, people will feel most comfortable when the temperature is 19 to 24℃ and the humidity is 40% to 50%.

The indoor temperature should not be higher than 24 degrees in winter, and the environment with humidity index of 50~60 is the most comfortable. When the room temperature is too high in winter, the indoor humidity is usually only 10%~ 15%RH. If you stay in such a room for a long time, you will feel uncomfortable. Therefore, we must pay attention to indoor ventilation in winter, that is, we can keep the air fresh, keep the temperature not too high, and pay attention to increasing humidity.

Tips for improving indoor humidity:

1. Indoor basin: You can put a basin of clean water indoors, and the water will evaporate naturally, thus improving the indoor humidity.

2. Use a humidifier: You can add clean water to the humidifier, and then turn on the humidifier, which will quickly increase the indoor humidity.

3. Planting plants indoors: You can plant some aquatic plants or green plants indoors, which can absorb water and increase indoor humidity through leaf evaporation.

4. Use a towel or bath towel: You can hang a wet towel indoors, or you can put the bath towel on the radiator to dry, so that the water can evaporate and the indoor humidity can be increased.

5. Mop the floor frequently: Mopping the floor frequently can let moisture penetrate into the ground and increase indoor humidity through evaporation.
