How many minutes should seniors vent their homes in winter?

✓ Accepted answer

During winter, seniors should ventilate their homes for just 5 to 10 minutes per room to maintain air quality without excessive heat loss.

• Follow the 20-minute rule: Experts advise opening windows fully for 20 minutes or less to refresh air; for older adults prone to chills, splitting this into two 10-minute sessions is safer and more effective.
• Use cross-ventilation: Open windows on opposite sides of the house to create a draft that quickly exchanges stale air with fresh oxygen, improving lung function for those with respiratory sensitivities.
• Target high-moisture areas: Prioritize venting the kitchen and bathroom for 5 minutes after showering or cooking to prevent mold and mildew, which can worsen chronic health conditions.
• Maintain a set temperature: Keep the thermostat at 20 degrees Celsius, but briefly lower the heat during the 10-minute ventilation window to prevent overheating the walls and reducing condensation risk.
• Consider mechanical aids: For those unable to manage drafts, a small energy-efficient extract fan can provide continuous background ventilation, ensuring consistent air exchange without the cold shock of opening windows.
• Monitor carbon monoxide: Ensure detectors are functional, as sealed homes with supplemental ventilation require regular safety checks to prevent gas accumulation during longer closed periods.
