HHU – and action!
Fact check: How do you catch a cold?

As an energy-saving measure, the thermostats at Heinrich Heine University (HHU) have been turned down to max. one line before level 3 to achieve the stipulated room temperature of 19 °C. How healthy is this limit? Can you become ill more quickly when temperatures are lower? Düsseldorf-based Professor Dr Ortwin Adams from the Institute of Virology provides answers:

Room temperature is irrelevant when it comes to infections. Appropriate clothing, sport/exercise and a balanced diet all boost the immune system.

Many rooms on campus are now somewhat cooler and some HHU employees are understandably concerned that they could catch a cold more quickly as a result. However, this is not backed up by studies: “Lower temperatures do not cause more colds. Colds are caused by viruses – i.e. if your office colleague is sneezing and coughing, you could also become infected,” says Professor Adams. In overcrowded rooms, there is also a higher risk that someone in the room is infected.

In addition to droplet infections from people sneezing and coughing, there is also the possibility of smear infections: Some germs can survive for days on smooth surfaces such as door handles or light switches, meaning that they can be passed on via these surfaces. “You can protect yourself by washing your hands thoroughly – a measure we are all familiar with – and doing everything you can to boost your immune system: eating a balanced diet, taking regular exercise, maintaining a normal weight,” says the virologist, who is planning to avoid full rooms and large-scale events as far as possible in the coming weeks.

Another tip from the medical expert: Air rooms properly and regularly. “Studies have shown that higher humidity in rooms is harmful to many viruses, so it is sensible in winter to ensure that rooms are not too dry and that you air rooms properly for a short period at regular intervals.”

Practical tip: Layers are in!
What is the best look for the office on winter days? It’s not always easy to decide first thing in the morning. We recommend lots of layers and scarves/shawls that you can put on when it gets colder.
