The ideal temperature for air conditioning at night to promote restful sleep is between 18°C (64°F) and 22°C (72°F).
Why This Temperature Range?
- Optimal Sleep Comfort: As indicated by the reference, aiming for this temperature range helps create the "goldilocks zone" for sleep. This avoids the issues of being too cold or too warm, both of which can disrupt sleep.
- Avoiding Disrupted Sleep: Setting your AC too low can cause restlessness and a fragmented sleep cycle. A temperature within this range avoids these issues.
- Temperature Preferences: While this range is optimal for most, individual preferences may vary slightly. Some might find the lower end more comfortable, while others might prefer the higher end of the range.
Impact of Incorrect Temperatures
| Temperature Issue | Impact on Sleep |
|---|---|
| Too Cold (Below 18°C) | Can cause restlessness, disrupted sleep |
| Too Warm (Above 22°C) | Can cause sweating, discomfort, poor sleep |
Practical Tips for Achieving the Ideal Temperature
- Start in the Middle: Initially set your AC within the 20°C (68°F) range and adjust slightly based on how you feel.
- Monitor and Adjust: After a few nights, you may need to fine-tune the temperature to reach your personal comfort level.
- Consider Room Size: A smaller room might cool down faster than a larger room, influencing the temperature you need to set on your AC.
- Use a Thermostat: A programmable thermostat can be beneficial to maintain a constant temperature throughout the night.
