During the summer, especially in a coastal city like Torrevieja where nights can be warm and humid, many people ask the same question: Is it unhealthy to sleep with the air conditioning on?
At AC Torrevieja, specialists in air conditioning in Torrevieja and heating systems in Torrevieja, we explain the truth behind the most common myths and how to use your AC properly to improve sleep quality without affecting your health.
🌡 Is Sleeping with Air Conditioning Harmful?
The short answer is: no, if used correctly.
The issue is not the air conditioning system itself, but rather:
- Setting excessively low temperatures
- Poor airflow direction
- Lack of maintenance
- Incorrect humidity levels in the room
A properly installed and adjusted system can actually improve your sleep quality.
❌ Common Myths About Air Conditioning and Health
“Air conditioning causes colds”
False.
Colds are caused by viruses, not by cold air. However, sudden temperature changes can temporarily affect your mucous membranes and increase sensitivity.
“Sleeping with AC dries out the air”
It depends.
Air conditioning reduces humidity, but this is not necessarily negative. In Torrevieja, where humidity levels are often high, lowering humidity can actually improve respiratory comfort.
“It causes muscle pain”
Not directly.
Muscle stiffness usually happens when cold air blows directly onto your body for several hours.
💧 The Importance of Relative Humidity
One of the key factors for quality sleep is maintaining the right relative humidity level indoors.
- The ideal range is between 40% and 60%.
- In summer in Torrevieja, humidity levels can easily exceed 70%.
High humidity creates a heavy, uncomfortable feeling and makes it harder to sleep. A properly installed air conditioning system in Torrevieja helps by both cooling and dehumidifying the air.
Excessively dry air (below 30%) may cause:
- Dry throat
- Nasal irritation
- Dry eyes
That’s why proper temperature and system adjustment are essential.
🌙 Ideal Temperature for Sleeping in Summer
Experts recommend sleeping at a temperature between 24°C and 26°C (75–79°F) during summer.
Lowering the temperature to 19°C or 20°C (66–68°F) not only increases energy consumption but may also cause:
- Sudden temperature shocks
- Muscle tension
- Feeling cold during the early morning hours
In Torrevieja’s coastal climate, moderate cooling is usually more than enough for a comfortable night’s sleep.
🛠 Tips for Sleeping with Air Conditioning Safely
Based on our experience installing and maintaining air conditioning in Torrevieja, we recommend:
✔ Avoid directing airflow straight at the bed
Adjust the vents so the air flows toward the ceiling or wall.
✔ Use “sleep mode”
Many modern systems gradually adjust temperature overnight.
✔ Keep filters clean
Dirty filters can accumulate dust, allergens and bacteria. Regular maintenance is essential.
✔ Avoid extreme temperature differences
If it’s 30°C outside, don’t set your AC to 18°C.
✔ Ventilate the room before bedtime
Fresh air improves indoor air quality.
🏖 Air Conditioning in Torrevieja: Essential for Summer Comfort
Torrevieja’s climate combines heat and humidity, which can make summer nights uncomfortable. A well-designed and properly installed air conditioning system:

🔚 In Summary
Sleeping with the air conditioning on is not harmful if:
- The temperature is set appropriately
