Question

Is sitting in AC harmful?

Answer 1

Sitting in air conditioning (AC) is not harmful **in general**, but there are a few things to keep in mind to stay healthy:

### ✅ When AC is **not harmful**:
- If the **temperature is comfortable** (around 22–25°C or 72–77°F), it helps you stay cool and fresh, especially in hot weather.
- AC can improve air quality **if it's clean and well-maintained**, by filtering out dust and allergens.

### ⚠️ When AC **can be harmful**:

1. **Too Cold Temperature**  
   Sitting for long in very cold AC (like below 20°C or 68°F) can cause:
   - Headaches
   - Muscle stiffness or pain (especially neck and back)
   - Cold or cough

2. **Dry Air**  
   AC removes humidity from the air. This can cause:
   - Dry skin
   - Dry eyes and throat
   - Irritated sinuses

3. **Poor Air Quality (Dirty AC filters)**  
   - Can spread dust, bacteria, or mold if not cleaned regularly
   - Can cause allergies, sneezing, or breathing problems

4. **Sitting too long in closed AC rooms**  
   - Low fresh air circulation can lead to tiredness or dizziness
   - May reduce oxygen levels slightly if room is sealed tightly

###  Tips to stay safe while using AC:
- Keep temperature **around 24°C (75°F)** — not too cold.
- **Clean the AC filters** regularly (every few weeks or as recommended).
- Use a **humidifier** or keep a bowl of water in the room to balance dryness.
- Open windows **once in a while** to let fresh air in.
- Don’t sit **directly in front** of the cold air.

In short: **AC is not harmful if used properly**. Just don’t overdo it or sit too long in freezing temperatures. Balance is key.
