Why do people feel so differently about the same room temperature?

Body build, clothing, activity level and humidity tolerance all play a part, and so does your seat. Someone directly under a vent feels much colder than someone near a sunny window, even though the thermostat reads the same number.

What are the advantages of each setting?

A warmer setting like 26°C (78°F) generally uses less electricity and makes the jump between indoors and outdoors easier on the body. A cooler setting like 20°C (68°F) cools down fast, feels crisp and dry, and suits people who run hot or are coming in from heavy heat.

Do people in other countries set their AC differently?

Yes. Habits vary with climate, humidity, building type and energy costs. Some places encourage moderate settings to save power, while others keep indoor spaces noticeably chilly, so there is no single worldwide norm.

Every summer, offices, homes and cars become the scene of the same quiet standoff over the thermostat. One camp prefers a moderate 26°C (78°F), citing lower energy bills, a smaller shock when stepping outside, and fewer chills from sitting under a vent all day. The other camp wants 20°C (68°F) with the fan blasting, because nothing beats walking into a cold room after a sweaty commute. Since people differ in body type, clothing, activity level and where they sit, the same room can feel perfect to one person and miserable to another.
