Internal doors can expand in winter due to increased humidity levels, causing the wood to absorb moisture and swell. To mitigate this, use a dehumidifier to reduce indoor humidity. Additionally, ensure proper insulation around doors and avoid placing them in areas with significant temperature fluctuations. If a door becomes difficult to close, lightly sand the edges but be cautious not to overdo it, as the door may shrink back in summer.
