Why two people feel different in the same room

Short answer: Two people in the same room can experience the temperature five degrees differently. Muscle mass, activity just before and what they have eaten explain most of it, and neither of them is wrong.

Same room, different experience

The thermometer shows the same for everyone in the room, but bodies do not experience it the same way. One sits in a t-shirt and feels fine, while the other has pulled a blanket over her legs. That is not because one is delicate, but because bodies produce different amounts of heat. The difference can be up to five degrees.

Muscle mass produces heat

Muscles give off heat even when you sit still. More muscle mass therefore means more heat from the body itself. That is one reason two people with different builds can experience the same room so differently. Whoever produces less heat has more need for a layer that holds on to it.

Activity just before matters

Someone who has just come in stays warmer for about half an hour. If you have cycled, walked fast or carried shopping up the stairs, the body has turned up the heat and does not turn it down straight away. Meanwhile, someone who has sat still for an hour has slowly cooled down.

Food and drink play a part

Digestion produces heat in the hours after a meal. If one person has just eaten and the other has not eaten for hours, it can be felt. Hot and cold drinks also affect the experience for a while. These are small differences on their own, but together with muscle mass and activity they explain why one feels cold.

The one who is cold can add a layer

It is easier to add a layer than to change the temperature for everyone in the room. Turn the heating up and one gets too warm, turn it down and the other is cold. An extra layer solves it for the person who needs it without affecting anyone else. It works at home and in most offices.

A thin layer close to the body

The layer that does the most is often the innermost. A thin layer close to the body holds the heat you produce yourself and is easy to wear under the clothes you already have on. It adds little bulk and can stay on all day. See bamboo t-shirts for women.

Cold feet are felt everywhere

If you are cold in a room where others feel fine, the feet are often part of the reason. The floor is usually the coldest place in the room, and cold feet can make the rest of the body feel cold. A pair of warm socks is a small step that often makes a noticeable difference. See socks for women.

Neither of you is wrong

It is easy to think one person is exaggerating. But both experiences are real. The bodies simply produce different amounts of heat at the same room temperature. Once you know that, it is easier to find a solution where both feel comfortable, instead of arguing about the thermostat.

Frequently asked questions

Why is one person cold and not the other

Because muscle mass, activity just before and what you have eaten all affect how much heat the body produces. The same room can therefore feel very different to two people.

Can you do anything about it

Yes, the one who is cold can add a layer. That is easier than changing the temperature for everyone in the room and does not affect those who already feel fine.

Is one of them wrong

No. Both experiences are real. The bodies simply produce different amounts of heat at the same room temperature, and that is completely normal.
