Comfort is a French term accepted by the dictionary of the Royal Spanish Academy (RAE) that comes from the English comfort. It is about what provides comforts and generates well-being to the user.
Comfort can be given by some physical object (an armchair, a mattress, a car) or by some environmental or abstract circumstance (the appropriate temperature, silence, the feeling of security).
According to abbreviationfinder.org, the human being tends to seek comfort at all times. In a work environment, such as an office, comfort is usually obtained from the use of a comfortable seat, which avoids back pain. An air conditioning system in summer and a heating system in winter also contribute to comfort at work, as do transport facilities to get to the place of employment or the availability of a dining room in the building.
At home, each person can seek their own comfort according to their interests and needs. Some associate comfort with the enjoyment of free time in their own homes, for which there is a wide range of products such as cinema systems, pool tables, swimming pools and hydromassage equipment, among many other offers for those who want to make their homes a complete relaxation center.
Beyond the possibilities of each one, the common moment for the search for comfort is on vacation, when everyone wants to relax and enjoy the absence of work obligations. In this case, some rent hotel rooms with all services paid, to minimize their domestic activities, while others find enough peace in a natural landscape.
Generally abbreviated as CH, the concept of hygrothermal comfort refers to well-being at a thermal level; in other words, it is the state in which the intervention of our thermoregulatory system is not necessary for the body to feel comfortable in a room. This phenomenon can be recorded to avoid exceeding the recommended rates and causing effects such as sweating.
Our organism has the necessary tools to act in the face of climate changes; However, this entails an expenditure of metabolic energy that can be avoided if a microclimate is generated, an environment that causes comfort. In normal situations, the body operates at an average temperature of 37 ° C, and is highly sensitive to increases in internal temperature: 6 degrees more are enough to produce serious consequences, including death.
The temperatures below normal are even more difficult to tolerate for our body when it reaches 35 ° C, which is considered hypothermia appears feeling drowsy and may go into a deep slumber.
A person who performs moderate physical activity, while sitting in a room, wearing light clothing, can achieve thermal comfort with an average temperature of 23 ° C. Another factor taken into account when defining hygrothermal comfort is relative humidity, which is usually taken as the source of discomfort, although our body tolerates it significantly, supporting levels of up to 75%.
It is also necessary to consider radiation, since the body perceives its changes with great precision; This can be seen in situations with a temperature lower than recommended but with sunlight entering through a window, which results in an increase in hygrothermal comfort. Radiant slab and radiator technologies are based on this same principle.
In short, the human body generates heat and exchanges it with its environment; all the thermal phenomena of which it participates must be studied when conditioning a room.
