What is the appropriate indoor temperature in winter?

The temperature is 12 ~ 14℃ for young people and 16 ~ 18℃ for old people.

Room temperature varies from person to person: young people have strong metabolic ability and relatively sound self-regulation ability. When stimulated by cold, skin blood vessels can contract to a greater extent to reduce the loss of body heat. So it is more appropriate to lower the temperature.

The elderly have decreased physiological function, aging skin, poor vascular elasticity and low metabolic level, which is more suitable for high temperature. Infants and young children are immature and have low thermoregulation ability, so they should pay attention to keeping warm, but their metabolism is strong and should not be overheated. Therefore, from the comfort point of view, the temperature of 12 ~ 14℃ is enough for young people, and 16 ~ 18℃ is more suitable for the elderly.

The room temperature should be adjusted according to the weather conditions:

The heating temperature in winter should not be too high: when the indoor temperature is above 22℃, the air will be extremely dry, and the hot environment will hurt people's body fluids and body fluids, making people feel hot and dry, and the eyes, ears, mouth, nose, throat and skin will be dry and uncomfortable. If the indoor temperature is too high for a long time, it will affect people's body temperature regulation function and cause body temperature to rise.

The heating temperature in winter should not be too low: when the temperature is lower than 12℃, 80% people sitting will feel cold, and 20% people who are active will feel cold, so hygiene takes 12℃ as the lower limit of building thermal environment. If the indoor temperature is too low, it will reduce the metabolic function of the human body.
