A wise scientist has urged people to ventilate their homes this winter to reduce the risk of Covid-19.
Professor Shaun Fitzgerald, who is a member of the Sage environmental working group, said opening a window at home is almost as important as social distancing and hand washing.
The Cambridge University scientist told the story the times that it is especially important when people are visiting.
But he warns that one has to be careful – as if it got too cold inside, it carries its own health risks.
“The greater the temperature difference between inside and outside, the more air flow there is,” said Professor Fitzgerald.
“So you can actually get away with not that much opening area in winter.”
But he added, “A little extra air has an advantage, but it lowers the ROI. When you freeze people, you run into other health problems.”
He also said air purifiers could help – but ventilating with fresh air is better where possible.
“It’s much better to ventilate a room with fresh air when you can,” said Professor Fitzgerald.
“But if you can’t, then these are worth a look. I wouldn’t turn there first, but I’m not saying I won’t turn there at all.”
His words about opening the window are endorsed by the Health and Safety Executive.

“Good ventilation can help reduce the risk of the coronavirus spreading, so focus on improving general ventilation, preferably through fresh air or mechanical systems.
“If possible, think about how you can maintain and improve the supply of fresh air, for example by opening windows and doors (except for fire doors).
“Also consider whether you can improve the outside air circulation and prevent stagnant air bubbles in occupied rooms. You can do this with ceiling fans or table fans, for example, as long as there is good ventilation.
“The risk of transmission from ceiling and table fans is extremely low, provided there is good ventilation in the area in which it is used, preferably fresh air.
According to The sunStudies of other infectious diseases like sars and influenza have found a reduction in the spread of the virus in buildings with better ventilation and air movement.
The Centers for Disease Control and Prevention, the leading American health agency, also says good indoor ventilation can help reduce the risk of the virus spreading.
It is said that homes, workplaces, schools and restaurants should “improve ventilation by opening windows or adjusting the air conditioning” to combat Covid.

It is said that poorly ventilated buildings can increase the risk of disease transmission.
The British Government ‘Hands. Face. Space campaign urges the public to continue washing their hands, covering their face, and making space to control infection rates and avoid a second peak.
Speaking of the government’s campaign, Chief Medical Officer Professor Chris Whitty said, “As winter approaches and we inevitably spend more time indoors, the public must follow this important advice to control the spread of the virus.
Hands. Face. Space highlights key elements of the guide that everyone should remember: wash your hands regularly, use face covering when social distancing is not an option, and try to keep your distance from those who don’t are in your household.
“Following these simple steps could make a significant difference in reducing the transmission of COVID-19 and help keep you and your friends, colleagues and family safe from the virus.”
Joseph Minott, executive director of the Clean Air Council, a Philadelphia-based environmental nonprofit, spoke about the virus outbreak. Opening a window is very important to get pollutants out of the house.
“What I always suggest in an unprofessional way is open the window and get some fresh air,” he said. “It’s something my mom swore by, and it’s something I do too – to get the stale indoor air out and the fresh air in.”
