Air conditioning has become an essential resource in our daily life, especially in summer. On a hot August day we could not last 5 minutes in the car, in the office, in a restaurant or in the cinema without the freshness that it provides.
While it is a faithful ally against heat, air conditioning can also harm your health and your pocket if not used correctly.
Air conditioning and your health
The Spanish Pneumology Society states that 20% of colds and half of sick leave due to colds are in the summer. Although not solely responsible, the temperature of the air conditioning is largely to blame.
The problems begin when a dry environment (below 30% relative humidity) is combined with a temperature difference of more than 10ºC from that on the street. This is when your throat and your entire respiratory system begin to suffer.
A badly used air conditioner is more than enough to turn your home into a cold, dry place. Pharyngitis, laryngitis, sinusitis, otitis... the list of afflictions is long and it includes muscular problems (cramp) and migraines if the cold air is directed at a person's head or back.
