Your bedroom could be the unhealthiest room in your home
Research indicates that bedrooms in energy-efficient, airtight homes often suffer from poor air quality due to high carbon dioxide levels accumulated overnight. While occupants often perceive the air as fresh, studies show that CO2 concentrations frequently exceed recommended health thresholds, potentially impacting sleep quality and cognitive function.
Why it matters
As homes become more energy-efficient and airtight, indoor air quality management is becoming a critical public health concern.
Close the door, shut the windows and turn up the heating, and you have all the ingredients for a sick bedroom in your home – and you spend about eight hours in there every night. <b>By Lala Rukh for The Conversation</b> Kitchens and bathrooms usually take the blame for stale air and damp. But researchers spent a winter monitoring airtight, naturally ventilated homes across Scotland. In more than four out of five homes the carbon dioxide (CO₂) in the air remained above the level considered a safe threshold for the entire night. Despite this, more than nine in 10 of the occupants thought the air in their bedroom was good. The reason is not the room. It is you. Awake in the living room, you are a thermostat with hands. When the air turns stuffy, you crack a window. When you feel cold, you close it.
