- Good ventilation ensures fresh air circulation, promoting better health and comfort for room occupants.
- Natural ventilation utilizes doors, windows, chimneys, and ventilation bricks, while artificial ventilation relies on fans and air conditioners.
- Effective ventilation helps cool the body by facilitating heat and perspiration evaporation.
- Overcrowding impedes air circulation, leading to poor ventilation and increased risk of disease transmission.
- Overcrowded spaces can cause discomfort, restlessness, and health issues such as headaches and sleeplessness.
