1. What temperature should the air conditioner be set to while sleeping?
Many people have the habit of setting the air conditioner at a low temperature of around 22 – 24 degrees Celsius when sleeping. However, this may not be beneficial for health because at night, the outdoor temperature drops. Turning on the air conditioner at a low temperature can lead to various respiratory diseases such as nasal inflammation, bronchitis, sore throat, etc. Therefore, the recommended temperature to set the air conditioner when sleeping is around 27 – 28 degrees Celsius.
If you feel hot when the air conditioner is set at 27 – 28 degrees Celsius, you can use an electric fan to regulate the air and increase ventilation, making the space cooler.
In addition, experts recommend using the 3 modes of the air conditioner in the summer, namely: Cool mode, Fan Speed mode, and Timer mode. These are considered the ideal modes for sleep.
Cool mode: This mode cools quickly, creates moisture to limit dry skin conditions. Moreover, this mode operates quietly, without causing noise, ensuring quality sleep.

Fan Speed Mode (at Medium level): This mode controls the fan speed on the air conditioner. It's advisable to use the Fan Speed mode at a medium level to avoid direct cold air when sleeping.
Timer mode: This mode allows you to actively set the air conditioner to turn off at your convenience. Towards morning, the outdoor temperature drops, so you can schedule the air conditioner to turn off a couple of hours before waking up to ensure health benefits and save electricity.

2. What temperature should the air conditioner be set to when a baby is sleeping?
Setting the appropriate air conditioner temperature for young children is crucial, as neglecting it can easily lead to dry skin and respiratory diseases.
For infants and children under 3 years old, the ideal temperature is around 28 – 30 degrees Celsius. Additionally, to ensure air circulation in the room, you should use an electric fan at the lowest setting. Note that you should not leave the child in the air-conditioned room for more than 4 continuous hours and must provide water for the baby.

3. Some considerations when using an air conditioner that should not be overlooked

- Avoid setting the air conditioner temperature too low; the temperature difference between outdoor and indoor should be around 7 degrees Celsius.
- Do not let the cold air flow from the air conditioner blow directly onto people, especially young children, to prevent respiratory problems.
- When coming in from the hot outdoors, avoid sitting directly under the air conditioner; instead, use an electric fan to gradually cool down.
- Avoid abruptly entering an air-conditioned room after being exposed to the sun; use an electric fan beforehand to cool down more effectively and prevent heat shock.
- Do not use the air conditioner when intoxicated with alcohol or beer as impaired judgment may lead to inadequate body warmth protection, increasing the risk of heat shock and cold symptoms.
- Avoid using the air conditioner when having a fever or sweating heavily as it may cause cold transmission, worsening the condition.
- Consider using ventilation fans or electric fans when using the air conditioner to ensure proper air circulation and even cooling throughout the room.
- Before going to bed in the evening, set the temperature and timer to avoid waking up in the middle of the night feeling too cold.
