Living in wrong temperature and humidity can cause illness.
Too Low Temperature: Cold air makes it difficult to maintain a healthy body temperature, especially for babies and seniors.
Too High Temperature: Prolonged exposure to high temperatures can cause a heat stroke.
Too Low Humidity: Dry air can cause itching joints, painful chapped lips, or even skin problems, including eczema and acne.
Too High Humidity: Moisture air leads to wood rot in poorly ventilated areas of your home.
Too High Temperature and Too High Humidity: The hotter it is, the more strain our bodies feel, and the more we need to sweat to cool down. But humid air has less capacity to hold additional moisture, so water evaporates more slowly and eventually causes overheating to your body. In this case, it is difficult for the fan to cool you unless the dehumidifier is used.
Having a thermometer and hygrometer at home, you can know the environment better and make smart decisions on when to use the air conditioner, heater, cooling fan, humidifier, or dehumidifier. Take appropriate actions in time to prevent you and your family members from being uncomfortable.
