The following is a list of the causes of human deaths worldwide for different years arranged by their associated mortality rates. In 2002, there were about 57 million deaths. In 2005, according to the World Health Organization (WHO) using the International Classification of Diseases (ICD), about 58 million people died. [1]
Diathermy is produced by two techniques: short-wave radio frequencies in the range 1–100 MHz (shortwave diathermy) or microwaves typically in the 915 MHz or 2.45 GHz bands (microwave diathermy), the methods differing mainly in their penetration capability. [4] [5] [6] It exerts physical effects and elicits a spectrum of physiological responses.
Microwave and other radio frequencies cause heating, and this can cause burns or eye damage if delivered in high intensity, [38] or hyperthermia as with any powerful heat source. Microwave ovens use this form of radiation, and have shielding to prevent it from leaking out and unintentionally heating nearby objects or people.
Diathermy equipment typically operates in the short-wave radio frequency (range 1–100 MHz) or microwave energy (range 434–915 MHz). [citation needed] Pulsed electromagnetic field therapy (PEMF) is a medical treatment that purportedly helps to heal bone tissue reported in a recent NASA study. This method usually employs electromagnetic ...
Microwave is a form of electromagnetic radiation with wavelengths shorter than other radio waves but longer than infrared waves. Its wavelength ranges from about one meter to one millimeter, corresponding to frequencies between 300 MHz and 300 GHz, broadly construed.
For instance, children who experience extreme weather-related trauma may struggle with ongoing emotional difficulties, including nightmares, regression in behavior, and difficulty concentrating.
More research is needed to understand this discrepancy and how the countries' well-being protocols and initiatives may, intentionally or not, mitigate the mental health risks of living in a winter ...
Unstable mental health, depression, suicidal thoughts and addiction to drugs and alcohol affect people of every age, every ethnicity, and every demographic group in every country in the world. However, data show that in recent years these problems are on the rise, especially among the US White non-Hispanic men and women in midlife.
