Do they create a better breathing environment? The general consensus of experts is probably “Yes they do!” As noted above, they work great for filtering airborne asthma triggers. They are also great at reducing humidity. The hotter the air the more water it holds.
People who live in air-conditioned surroundings report greater rates of respiratory symptoms, such as wheezing and shortness of breath, according to a study published in the Journal of Environmental Health Research. The results of the study were ascribed to greater exposure to pollutants and allergens indoors.
Cold air may worsen asthmatic bronchoconstriction but can lessen breathlessness in normal individuals. Patients with COPD sometimes report improvement in their dyspnea in cold weather.
They cool and dehumidify the air but do not remove oxygen. However, in a completely sealed room, oxygen levels may gradually drop over time due to respiration. Yes, we still receive oxygen when the room is closed and the air conditioner (AC) is operating.
The cold air produced by the AC can irritate the respiratory tract, causing symptoms such as coughing, wheezing, chest tightness, and shortness of breath. Additionally, AC units can circulate allergens and airborne pollutants if not properly maintained, exacerbating respiratory symptoms for susceptible individuals.
WHAT SHOULD I SET MY AC TO AT NIGHT? According to the Cleveland Clinic, the recommended thermostat setting for nighttime is between 60°F and 67°F. 3 Setting your AC within this range can help maintain a comfortable sleeping environment.
Evaporative and refrigerated air conditioners can increase humidity levels, which may increase the risk of mould or house dust mites, which can be a trigger for asthma. Reverse cycle air conditioners may assist in lowering indoor humidity.
AC doesn't ventilate a room. It cools a room. The equipment may have a ventilate function also, but the primary function of AC is to create cool. If you turn the control to "ventilate” it will bring in some fresh air, and might even open a small damper to allow some stale air to be ejected.
Most research shows that VO2max is generally unaffected by cold exposure, however the majority of research suggests that sub-maximal O2 consumption increases for a given workload [1].
Sleeping with your bedroom door closed can help maintain your desired temperature, which is crucial for a restful night's sleep. In the summer, sleeping with your bedroom door closed can help keep the air conditioning in, while in the winter, it can help keep your bedroom warm and toasty.
“[We have] shown that increasing warmth leads to improvements in health for most respiratory diseases, and our recently completed Housing, Heating and Health Study found warmer temperatures improved the respiratory symptoms of children with asthma,” she says.
However, cold air can also be dangerous. While crisp weather can be healthier for many people, those with asthma need to be careful. Cold weather can sometimes cause them to have trouble breathing. Additionally, we all need to remember to bundle up when temperatures drop!
According to pulmonologist Dr. Michael Scharf, inhaling cold air may cause bronchial irritation and cough. If you have asthma or chronic obstructive pulmonary disease (COPD), the cold air “may induce bronchial tightening or constriction leading to cough, wheeze and shortness of breath.”
Before going to sleep, the air conditioning temperature must be regulated so that it varies between 24ºC - 26ºC in summer and between 15ºC - 17ºC in winter. The environment will be suitable, without exposing your body to sudden changes that may adversely affect it.
The findings of this study suggest that additional indoor cooling may improve COPD respiratory health during the warmer months and that consideration should be given when traveling outdoors in warmer weather.
Shortness of breath does not always indicate that you are hypoxic. In other words, your level of dyspnea, or air hunger, does not always correlate with your oxygen saturation. This means that you can be short of breath, even extremely short of breath, even in the presence of normal oxygen saturation.
Cold air can trigger your lungs to produce histamine, which can cause an asthma flare in the winter. Stay warm all season to reduce your risk of an asthma attack: Bundle up in a warm coat and gloves. Cover your mouth and nose with a mask or a scarf.
What is known is that hotter air has the capacity to absorb and carry more water vapor than colder air. In other words, the hotter the air, the higher the humidity tends to be. That said, hot and humid air is thicker and heavier, and, therefore, harder to inhale.
Air conditioning can be good for asthma as it helps regulate temperature and humidity, but if not properly maintained, it can worsen IAQ and trigger asthma symptoms. Strategies to improve IAQ and mitigate these risks include regular maintenance, high-quality filters, and adequate ventilation.
How, then, to keep your IAQ A-OK? Prevailing wisdom is that at least 5 minutes—and ideally 15 to 20 minutes—a day of ventilation significantly improves indoor air quality. For a strong ventilation, open the front and back door, along with windows on the path in between, to get the baddies out.
Air conditioners are commonly used around the country during the warmer months. But if you are living with bronchiectasis, the colder air circulating from air conditioning could trigger worsening of symptoms such as cough or breathlessness. Triggers differ between individuals.
Ideal conditions for patients with COPD to minimize risk for exacerbation would be home humidity between 30% and 50% with indoor temperature of 21°C at least 9 hours per day in living areas (Osman, et al.
Therefore, mild temperatures and low humidity are recommended. According to a small study in the American Journal of Respiratory and Critical Care Medicine Trusted Source, a room temperature of 68 to 71°F (20 to 21.6°C) is ideal for people with asthma.
