Heating is the key to combating the low temperatures in winter. However, it is important to note that, just as they can provide comfort, it can also be hazardous to health depending on the heating system and the temperature at which it is used.
Therefore, the Argentinean Association for Respiratory Medicine shares information about the care that must be taken into consideration in order to heat with caution.
Ideally, the temperature at which an environment is heated is not above 21-223 ° and the humidity is between 50 and 70%. Excessive heat increases the temperature contrast between inner and outer, which can reduce the body's defensive mechanisms.
The supply of heating systems is quite wide, but we cannot say that any of these units meet the ideal conditions.
The units that work with combustion consume oxygen and release harmful gases, among which carbon monoxide exists.
Some devices derived from gases that are hazardous to health are:
Fireplaces or heaters for kerosene.
Gas or wood stoves.
The defective combustion of the material used to produce heat or insufficient ventilation system can cause the accumulation of dangerous levels of these harmful gases.
It is important to know that carbon monoxide is an imperceptible gas because it is colorless, odorless and because it does not irritate the mucous membranes, but it accommodates oxygen in the blood, preventing it from reaching the various organs and tissues.
The poisoning of this gas can culminate in cardiorespiratory arrest and death. In the case of poisoning to a lesser extent, there may be headaches, nausea, weakness, dizziness etc.
Another dangerous gas is nitrogen dioxide, which is released when cooking ovens, gas ovens and paraffin stoves do not work properly. This gas cannot be closed or seen, but it is irritating to mucous membranes and can cause respiratory distress, especially in asthmatic patients, with COPD or other chronic respiratory diseases.
There are other products derived from poor combustion, especially on coal and wood ovens or fireplaces, which are particles of such small size that they can be deposited in deep locations in the bronchial tree, in order to promote the appearance of chronic respiratory diseases (such as COPD) or tumors .
Hot air heating systems, such as hot / cold air conditioning, tend to dry out the environment, which also causes the airways to lose moisture. Respiratory resection reduces its defense mechanisms that promote infections and can generate nasal overload or cough, especially in allergic patients, or it may favor asthmatic exacerbations in those suffering from this pathology.
It is important to remember that the hot air circulation draws dust particles containing allergens, substances that promote the triggering of allergic symptoms.
The most recommended heating systems, especially for those suffering from chronic respiratory diseases, are certain types of ovens, for example:
Heater having a closed combustion chamber system with external evacuation of the gases generated as a result of combustion.
Despite the above-mentioned disadvantages of the different heating systems, it may be more harmful to health not to heat in cold times of the year. It is recommended that the surroundings are warm, well ventilated and sunny as the sun decreases dust mites and maintains the temperature.
5 recommendations for heating with caution
Make sure all heat sources work properly: Follow all manufacturer's instructions carefully to start and use the devices.
Exhausts outside: When using some heat sources, it is necessary to take into account that they have sufficient outside output, and if not, be careful about opening a window so often to vent the cab where it is located.
Turn off the heat at night: It is also recommended to ventilate the house before it lights up in the morning.
Regularly clean the air conditioning filter: This unit is one of the most drying environment and mucous membranes, in addition to collecting various substances in the filters that it is important to clean regularly.
Avoid waste sources that generate waste: such as cigarette smoke, incense, incense etc.
