9. User Tips for a Healthy Environment
Maintaining optimal temperature and humidity levels is crucial for comfort and health. Here are some guidelines:
9.1. Comfortable Parameters for Home Space
| Room Type | Summer Humidity | Winter Humidity | Summer Temperature | Winter Temperature |
|---|---|---|---|---|
| Baby room/Elderly room | 50%-70% | 45%-65% | 22°C-26°C | 18°C-24°C |
| Living room/Dining room/Bedroom | 50%-70% | 45%-65% | 18°C-25°C | 16°C-25°C |
| Study | 50%-70% | 45%-65% | 22°C-26°C | 18°C-22°C |
9.2. Health Tips about Temperature and Humidity
- Anti-mites/mold: It is recommended to control indoor humidity below 65%. An environment with a temperature of 20°C to 30°C and humidity of more than 70% is a breeding ground for mites/mold.
- Prevent flu: Influenza virus loses its infectivity in an environment with humidity above 55%. When the air humidity is lower than 40%, the infectivity of influenza virus will become more infectious.
- Prevent asthma: Dry air can exacerbate asthma. Try to maintain a comfortable humidity level, especially when the temperature drops by more than 5% compared to the previous day.
