Ventilating homes and offices reduces airborne virus concentration, expert says

Cardiology professor Khaled Al-Nemer has advised people to ensure proper ventilation in their homes.

Writing on the X platform, Al-Nemer said that ventilating homes and offices daily for a few minutes, even in cold weather, significantly reduces the concentration of viruses lingering in indoor air.

He added that keeping windows completely closed throughout the season increases the risk of infection.
