What is ideal temperature to set for your Room

​

We’ve all been there. One person in the house is wrapped in a blanket like it’s winter, and the other is sitting there in shorts saying, “It’s still too warm.” So what’s the actual right number to set your air conditioner to?

After looking at what energy experts and HVAC technicians actually recommend, the answer is pretty consistent: 24°C is your sweet spot when you’re at home and awake.

Let me explain why—and when you should break the rule.

Why 24°C Just Works

At 24°C, most people feel comfortable. Not too cold, not too warm. More importantly, it’s cool enough to pull humidity out of the air (that sticky, heavy feeling is usually the real problem, not the heat itself). And here’s the kicker: every degree you go below 24°C bumps up your electricity bill by roughly 8%. So dropping to 20°C feels nice for about ten minutes, then your wallet starts sweating.

For Sleeping: 23°C to 25°C

Your body naturally cools down when you sleep. If your room is too cold—say, below 22°C—you might wake up with a stiff neck or a dry throat. Too warm, and you’ll toss and turn. Most people sleep best somewhere between 23°C and 25°C. Try starting at 24°C and adjust by one degree from there.

When You’re Out: 28°C to 30°C

A lot of people turn the AC off completely when they leave. Don’t. The humidity will build up inside your home, and that’s how you end up with musty smells or even mold. Instead, set it to around 28–30°C. It won’t run much, but it’ll keep the dampness away and save you energy.

Who Might Need It Cooler?

· Older folks and babies don’t regulate heat as well. For them, 23°C is safer, especially during a heatwave.

· If you work from home and your PC or laptop turns your desk into a furnace, you might want 22–23°C just to stay functional.

When It’s Actually Too Cold

Look, setting your AC to 18°C feels amazing for the first three minutes after walking in from outside. But keeping it there? Not great. Cold air dries out your sinuses (hello, sore throat), can make your muscles feel tight, and honestly, your electricity bill will be painful. It’s just not worth it.

One Simple Trick Before You Turn It Down

If you’re sitting at 24°C and still feel warm, don’t touch the thermostat. Turn on a ceiling fan or a standing fan instead. The moving air makes you feel about 3–4°C cooler without changing the actual temperature. You stay comfortable, and your AC doesn’t have to work harder. That’s a win-win.

Bottom Line

· Home and awake: 24°C

· Sleeping: 24–25°C

· Out of the house: 28–30°C

Set it, forget it, and stop fighting over the remote. Your body and your electricity bill, will thank you.
