Studies have been performed on the use of shortwave radiation for cancer therapy and promoting wound healing, with some success. However, at a sufficiently high energy level, shortwave energy can be harmful to human health, potentially causing damage to biological tissues, for example by overheating or inducing electrical currents.

Health policy and health systems can have impacts on deaths and thereby may also be a factor of deaths, also including for example education policy (e.g. health illiteracy), climate policy (e.g. future water scarcity impacts) and transportation policy (e.g. motor vehicle accidents, pollution and physical activity), [citation needed] as well as ...
Recognized effects of higher acute radiation doses are described in more detail in the article on radiation poisoning.Although the International System of Units (SI) defines the sievert (Sv) as the unit of radiation dose equivalent, chronic radiation levels and standards are still often given in units of millirems (mrem), where 1 mrem equals 1/1,000 of a rem and 1 rem equals 0.01 Sv.
Blue light has a significant impact on numerous physiological processes in human health. [3] The widespread use of blue light in modern technology brings up a concern about the potential consequences of excessive blue light exposure. [4] Such exposure has been associated with disruptions in ocular health, sleep patterns, and well-being. [4] [5]
Aldehydes may cause harmful health effects; though, in the majority of cases, the amounts inhaled are less than with traditional cigarettes. [225] A 2016 study found that e-liquids without flavoring generated no aldehydes, which indicated that the flavors were causing the creation of aldehydes, according to a 2018 PHE report. [249]
The U.S. Food and Drug Administration (FDA) now classifies eggs as a “healthy, nutrient-dense" food, according to a new proposed rule. Registered dietitians react to the change.
Growing evidence suggests marijuana may be linked to certain heart problems. What's not clear is whether the heart risks are from smoking or if it’s the THC in weed that could be harmful.
But, in a section of the study on “Health and Exposure Concerns,” the researchers said that amount “would approach” the established safe exposure limit set by the EPA (also known as a ...
