Infrared (IR) is an electromagnetic wave with a frequency between microwave and visible light, and a wavelength between 760nm (nanometers) and 1mm (millimeters). It is invisible light with a lower frequency than red light.
Ultraviolet (UV) is a general term for radiation with wavelengths ranging from 400nm to 10nm in the electromagnetic spectrum, which cannot cause visual impairment. It is an invisible light with a frequency higher than blue violet light.
The difference between infrared and ultraviolet radiation
(1) Different wavelengths
1. Infrared is an electromagnetic wave with a wavelength between microwave and visible light, ranging from 760 nanometers (nm) to 1mm (mm), and is a longer non visible light than red light.
2. Ultraviolet radiation refers to the general term for radiation with wavelengths ranging from 10nm to 400nm in the electromagnetic spectrum, which cannot cause visual impairment.
(2) Different functions
Infrared radiation is also widely used in daily life, such as high-temperature sterilization, monitoring equipment, infrared interfaces for mobile phones, hotel door cards, TV remote controls, etc., all of which have the shadow of infrared radiation. In addition, infrared radiation can improve blood circulation, increase cell phagocytic function, eliminate swelling, promote inflammation dissipation, and treat chronic inflammation.
2. Ultraviolet radiation has sterilization and health benefits, and can also promote the production of vitamins, decompose oil fumes, and break down organic matter in the human body. Short wave ultraviolet radiation has extremely strong destructive power on microorganisms. When the ultraviolet radiation in this wavelength band irradiates the bacterial body, the nuclear protein and deoxyribonucleic acid (DNA) of the cell strongly absorb the energy in this wavelength band, and the chains between them are opened and broken, causing the bacteria to die.
(3) Excessive intake poses different risks to the human body
Infrared radiation is a type of thermal radiation that can cause high temperature damage to the human body. Strong infrared radiation can cause skin damage, similar to burns, initially resulting in burning pain and then causing burns.
When ultraviolet radiation strongly acts on the skin, photodermatitis can occur, resulting in redness, itching, blisters, edema, eye pain, tearing, and other symptoms on the skin; Severe cases can also cause skin cancer. Ultraviolet radiation acts on the central nervous system and can cause headaches, dizziness, and elevated body temperature. you can consult 365nm and 395nm UV light on http://www.benweilight.com
