Several factors could contribute to struggling with breathing while in your house. One common cause is poor indoor air quality, which can be influenced by various factors such as inadequate ventilation, dust, allergens, or contaminants like smoke or chemical irritants from cleaning products. Maintaining clean living spaces and ensuring proper ventilation may help alleviate respiratory discomfort caused by these triggers. Other possibilities might include hidden mold growth or high humidity levels within your house, both of which can aggravate existing respiratory conditions or induce new symptoms. If you consistently struggle to breathe indoors even after addressing potential triggers and maintaining good hygiene practices within your home environment, it is advisable to consult with a healthcare professional to identify any underlying health issues or allergies that may be contributing to the problem.
