Stop Setting Your Air Conditioner to 26°C? Experts Say Another Temperature May Save More Electricity and Feel Better for Your Health

During extremely hot weather, many families immediately lower the air conditioner temperature to 26°C or even colder to cool the room faster. However, energy and health experts say this popular habit may not always be the best choice.

Specialists explain that choosing the right air conditioner temperature not only affects electricity bills but may also impact sleep quality, respiratory comfort, and overall health.

Why Extremely Low Temperatures May Not Be Ideal

Many people believe colder air automatically means better comfort. But experts warn that setting the air conditioner too low may cause:

• Dry skin
• Sore throat
• Nasal irritation
• Muscle stiffness
• Temperature shock when moving outdoors

Large temperature differences between indoor and outdoor environments may also place stress on the body, especially during heat waves.

Experts Recommend a More Balanced Temperature

According to specialists, many households may feel comfortable and save more electricity by setting the air conditioner around:

• 27°C
• 28°C

especially when combined with:

• Electric fans
• Proper ventilation
• Curtains blocking sunlight
• Good room insulation

Experts say the body often adapts better to moderate cooling rather than extremely cold air.

Why Higher Settings May Save More Electricity

Air conditioners consume more electricity when forced to maintain very low temperatures continuously.

Energy experts explain that each degree lower may significantly increase power consumption, especially during long overnight use.

Moderate settings may help:

• Reduce electricity bills
• Extend air conditioner lifespan
• Lower energy waste

Sleeping in Very Cold Air May Affect the Body

Doctors say sleeping for many hours in very cold air may increase:

• Dry throat
• Muscle discomfort
• Nasal congestion
• Respiratory irritation

Young children, elderly people, and individuals with sinus or respiratory problems may be more sensitive to excessive cooling.

Additional Tips Experts Recommend

To improve comfort while saving energy, specialists suggest:

• Cleaning air conditioner filters regularly
• Using timer mode at night
• Combining AC with fans
• Keeping doors and windows sealed
• Avoiding sudden extreme temperature changes

Hydration is also important during hot weather because air conditioning may dry indoor air.

The Bottom Line

Experts say the “best” air conditioner temperature is not necessarily the coldest one. Moderate cooling around 27–28°C may help many households balance comfort, health, and electricity savings more effectively.

Choosing smarter cooling habits may improve sleep quality while also reducing energy costs during extreme heat.
