There are many different ways for you to get sick -- here are some of them: Mechanical damage - If you break a bone or tear a ligament you will be "sick" (your body will not be able to perform at its full potential). The cause of the problem is something that is easy to ...

That's smaller than pollen grains (5–10 microns) or red blood cells (10–30 microns), roughly the same size as "typical" bacteria (1–5 microns is a good rule of thumb), but still bigger than most viruses (which tend to be smaller than 0.5 microns). Since microfibers can't ...
Since microplastics are commonly found in indoor dust, one way to reduce exposure is to invest in filters that target small particulates. HEPA filters, for example, are designed to remove “99.97% of dust, pollen, mold, bacteria, and any airborne particles with a size of 0.3 microns.” (36...
Alternatively, these layers are also comparable to the oscillatory zoning found in many minerals, where it is believed that a kinetic feedback mechanism results in periodic oscillations of crystal growth and impurity occlusion independent of biological activity42. Further analysis of the composition and...
The COVID-19 pandemic has revived a decades-old debate about how respiratory diseases travel—which affects the safety practices experts recommend.
The causes of indoor air pollution are plentiful. Some are readily recognized due to their smell, but many others go undetected. Tobacco smoke The smoke from cigarettes, cigars, and pipes is one of the most common—and most dangerous—indoor air pollutants.Tobaccosmoke contains more than 7,000...
Many cultures around the world do this to prevent outside grime from entering their tidy homes via the bottom of someone's shoe. Such a policy may help reduce the number of allergens entering the home (grass pollens, in particular), not to mention pesticide residues from the lawn, mold ...
microns size or more. To give you some context, human hair is 17-181 microns thick. HEPA filters are great at removing dust, pollen, mold spores, mildew, pet dander, dust mites, soot, and many airborne pathogens. They are also helpful in filtering cigarette and wildfire smoke, but they ...
Between the capillaries and the alveolus is a thin wall (about 0.5 microns thick) through which various gases (oxygen, carbon dioxide and nitrogen) pass. When you inhale, the alveoli expand and take in oxygen. Because the oxygen concentration is high in the alveoli and low in the blood ...
