Air conditioning is our best friend in summer. However, just as we are not glued to our best friends 24/7, neither should we be glued to the air conditioning. While a friend may run out of gossip to share, over-dependence on air conditioning can pose serious health risks and strain your budget.
Understanding Thermoregulation
Thermoregulator, what for? As explained in an article by Meteored, one of the biggest problems with overusing air conditioning is that our natural thermoregulation system becomes a little lazy. Human beings are homeothermic animals, maintaining a stable temperature around 36.5ºC, whether it’s 0ºC or 42ºC outside. Our bodies naturally adapt to temperature changes—sweating in heat, shivering in cold. But if we spend too long in a chilled environment at 19ºC, our body struggles to adapt when stepping outside.
This issue extends to sleep as well. Our body temperature drops gradually during the night, a process guided by circadian rhythms. If we artificially lower the temperature with air conditioning, it can disrupt our ability to rest.
Health Risks of Overusing Air Conditioning
Dry Mucous Membranes
Dry mucous membranes. Air conditioning does more than just lower the temperature; it also dries out the air. This can lead to that uncomfortable dry nose and throat sensation that many experience after prolonged exposure to cool air. This dryness is especially evident at night.
The real danger is that our mucous membranes serve as a barrier against respiratory pathogens. The moisture found in these membranes aids cilia movement to trap and expel viruses and bacteria. It’s essential to note that while the cold doesn’t cause colds—viruses do—reduced humidity can hinder our body’s defenses against these pathogens.
Muscle Pain
Muscle pain. Extended time in an air-conditioned environment can lead to muscle stiffness and pain. Cold air causes our muscles to constrict, making it common to experience discomfort.
Best Practices for Using Air Conditioning
Keep Temperature Differences Minimal
No more than 12 ºC difference. While air conditioning is invaluable, it should not be overused or set too cold. As noted by Dr. Sandra Dorado, coordinator of the Respiratory Diseases area of the Spanish Society of Pulmonology and Thoracic Surgery (SEPAR), transitions between environments should not exceed 12ºC. Gradual acclimatization is key to avoiding health issues.
Cleaning is Crucial
Additionally, keeping air conditioning filters clean is essential. Dirty filters can lead to respiratory issues and poor air quality. Thus, enjoy your air conditioning, but just as you would with a friend, give it a break from time to time and ensure you maintain it properly.
