Example 1: The test person sits on a chair and exhales through their noseįigure 1 of the title picture shows the typical dispersion of aerosols. Typical everyday situations were taken into account, such as those often found in schools, daycare centers, offices, and on public transport. The mask was tested under realistic and real-life conditions, says the scientist. The researchers tested a transparent shield made by a Southern German manufacturer, which is very common and is increasingly being used in schools and daycare centers. He is a Professor of Medical Technology and Medical Informatics at the Faculty of Applied Natural Sciences and Mechatronics at the University of Applied Sciences in Munich and the science director of this pilot study. “We can measure exactly how the spread of aerosols is influenced by masks of this type with our test set-up,” says Prof. These transparent masks have now been tested for their effectiveness at the Munich University of Applied Sciences (HM). But do they also serve their purpose? Do they catch exhaled aerosols? Many experts are critical of this design. You can see someone’s facial expressions – in contrast to the traditional mouth-nose protection, which covers the face from the chin to almost the eyes – and they are more convenient to wear and more comfortable. The advantages of these types of masks are also obvious. Nevertheless, according to the current infection control regulations in the German state of Bavaria, they are officially considered to be mouth and nose coverings. Even if they do not really cover the mouth and nose … because there’s a gap of one to several centimeters between the face and the lower side of these shields. They are enjoying increasing popularity as an alternative to conventional mouth-nose coverings.

In a 2002 study from the University of Oxford, researchers found that people who engaged in “imagery distraction” fell asleep faster than those who had general distraction or no instructions. Some say that visualizing something can make it real, and it’s possible this works with sleep, too. If counting activates your mind too much, try engaging your imagination. If you often find yourself stressed out about trying to sleep, this method may be more effective than traditional, intentional breathing practices. Research has found that people who practiced paradoxical intention fell asleep faster than those who didn’t. Try these techniques! Tell yourself to stay awakeĪlso called paradoxical intention, telling yourself to stay awake may be a good way to fall asleep faster.įor people - especially those with insomnia - trying to sleep can increase performance anxiety.

If the previous methods still didn’t work, there might be an underlying blockage you need to get out.
