Ventilation requirements of classrooms and dormitories in cold weather

Ventilation requirements for classrooms and dormitories in cold weather are as follows:

Regularly open windows for ventilation: Before and between classes, windows in classrooms and corridors should be used for ventilation at least twice a day for at least 20 minutes each time. This can ensure indoor air circulation and reduce the possibility of bacterial growth. Keep the indoor air fresh: pay attention to the ventilation of the room to reduce and inhibit the reproduction of germs and viruses. But at the same time, we should also pay attention to keep warm to avoid the indoor temperature dropping too fast due to too long ventilation time.

Improve the relative humidity of indoor air: You can use a humidifier or put a basin indoors to improve the humidity of indoor air and prevent discomfort caused by excessive dryness. Pay attention to personal hygiene: maintaining good personal hygiene habits, such as washing hands frequently and wearing masks, can help prevent the spread of respiratory diseases. Avoid contact with the source of the disease: try to avoid contact with people or animals that have been infected with respiratory diseases to reduce the risk of infection.

Ventilation can prevent viruses and bacteria from breeding: when indoor air is not ventilated, viruses and bacteria are easy to breed and increase the risk of infection. Ventilation can effectively reduce the number of viruses and bacteria and reduce the risk of infection. Allergen reduction: Ventilation can reduce the number of indoor allergens, such as pollen and dust, thus reducing the occurrence of allergic reactions.

Increase oxygen content: Ventilation can increase indoor oxygen content, making people breathe more smoothly and have more energy. Eliminating odor: Ventilation can eliminate indoor odor, such as smoke and mildew, and improve indoor air quality. Prevent humidity: When the weather is cold, the temperature difference between indoor and outdoor is large, which easily leads to indoor humidity. Ventilation can effectively prevent moisture and avoid problems such as moldy walls and damp furniture.

Importance of ventilation

Ventilation is very important in our life, which not only affects our health, but also affects our mood and quality of life. Ventilation improves indoor air quality: ventilation can effectively improve indoor air quality, expel indoor dirty air and introduce fresh air. This helps to reduce the content of harmful substances such as bacteria and viruses indoors and reduce the risk of infection.

Promote metabolism: Ventilation can help us breathe more oxygen and promote human metabolism. This helps to improve our body immunity, relieve fatigue and stress, and improve our body function. Relieve psychological stress: Long-term closed environment can easily lead to psychological stress. Ventilation can relieve this pressure and make people feel more comfortable and relaxed.
