    The infrared rays in sunlight have a different damaging effect on ** than ultraviolet rays. Ultraviolet light mainly causes photochemical and photoimmunological reactions, while infrared irradiation produces reactions due to molecular vibrations and increased temperatures. Infrared-induced thermal radiation penetrates more than ultraviolet rays.

    25% to 65% of the radiation reaches the epidermis and dermis, and 8% to 17% reaches the subcutaneous tissue. Through its thermal radiation effect, infrared rays directly cause adverse effects on ** temperature increase, telangiectasia, congestion, increase epidermal water evaporation, etc. It is characterized by red papules, premature aging, and pigment disorders.

    **Temperature increases, telangiectasia and congestion, and increases epidermal water evaporation, etc., directly cause adverse effects. Infrared rays can also enhance the damaging effect of ultraviolet rays on the aging process. SPF (Sun Protection Factor) measured outdoors in natural sunlight is significantly lower than in laboratory artificial light sources using the same sunscreen and UV intensity of the same energy, due to the dual effects of UV and infrared rays in natural sunlight.

    The essence of light is actually electromagnetic waves, including infrared, visible light and ultraviolet light, but the frequency is much higher than that of radio waves used in mobile communications. Infrared and visible light are harmless to the human body, and an appropriate amount of ultraviolet light can also kill the human body, but too much irradiation will be harmful to the human body, such as carcinogenic. Sunlight contains ultraviolet rays.

    X-rays, Y-rays, cosmic rays, etc., which are higher than the frequency of light, among them, X-rays, which are commonly used in hospital chest X-ray equipment, are definitely harmful to the human body if they irradiate the human body for a long time. There have been examples of long-term exposure to X-rays causing cancer. I hope the above is helpful to you, and I wish you a happy day!

    Is infrared harmful to people?This is a very common question. Before we get there, we need to know some basics.

    Infrared is an electromagnetic wave with a wavelength range of microns. Infrared rays in this range are divided into three categories: near-infrared, mid-infrared, and far-infrared. Among them, the near-infrared wavelength is the shortest, and the far-infrared wavelength is the longest.

    Are these infrared rays harmful to the human body? In fact, infrared radiation is also emitted from inside our bodies. As for the infrared radiation received from the outside world, as long as the energy received does not exceed the limit that the body can bear, it will not cause direct harm to the human body.

    Therefore, low-intensity infrared rays generated by ordinary electrical appliances and heaters that are exposed to in daily life do not cause obvious health hazards.

    In some specific cases, high-intensity infrared rays can be harmful to the human body. For example, if you work in a hot environment or are exposed to direct sunlight for a long time, you may be "burned", causing rashes, blisters, and other reactions. The eyes can also be damaged, causing symptoms such as redness, swelling, pain, etc.

    How can we prevent these hazards?Minimize the time spent working in a high-temperature environment. If you must work in a hot environment, be sure to wear appropriate protective gear.

    Pay attention to sun protection when exposed to the sun for long periods of time, and you can choose protective measures such as wearing sunglasses. It is also important to be safe when using electrical appliances at home, choose products with reliable brands, and follow the correct way to use them.

    Low-intensity infrared rays exposed to in daily life do not cause significant harm to the human body. However, in some specific cases, high-intensity infrared rays may be harmful to the human body. Therefore, it is necessary to pay attention to safety and take corresponding protective measures when using electrical appliances and working in a high-temperature environment.

    Infrared rays do not directly harm the human body, but if you come into contact with the infrared rays emitted by high-temperature objects for a long time, it will cause burns and sunburns. If exposed to strong sunlight for too long, it can also cause damage to **.

    In addition to the effects on **, prolonged exposure to infrared light emitted by hot objects can also lead to dehydration and heat stroke. Excessive loss of water in the human body can cause discomfort such as lower blood pressure and rapid heartbeat, and even endanger life and health.

    High-energy infrared radiation sources used in some industrial sites or laboratories can cause eye damage. If you look at these radiation sources for long periods of time without protection, it can lead to blurred vision, eye strain, and even blindness.

    Although infrared rays cannot directly cause harm to the human body, we still need to pay attention to avoid prolonged exposure to infrared rays emitted by hot objects, and take protective measures if necessary to protect our health.

Far infrared rays are among all the sunlight, he can penetrate the best and subcutaneous tissues, promote blood circulation, keep the body at a certain temperature, far infrared rays are also a kind of electromagnetic waves, can be quickly absorbed by the human body, and the far infrared rays that penetrate into the human body will cause the vibration of atoms and molecules, and then absorb through resonance, forming a thermal reaction, promoting the temperature of the deep subcutaneous layer, the dilatation of fine blood vessels to promote blood circulation, and remove all the obstacles that hinder metabolism such as blood congestion, resurrect the tissues, and promote the growth of enzymes. The old waste and harmful substances that were originally retained in the body will be excreted from the body by the sweat glands with metabolism, and the cosmetic residues existing in the pores can be directly excreted from the body without passing through the kidneys, which can avoid increasing the burden on the kidneys. The far-infrared photoheat released by the self-heating floor of the polar sun is between 5-15 microns, which is consistent with the 9 micron wavelength of the human body, and the warming effect of the far-infrared rays can accelerate blood circulation, improve the microcirculation of brain tissue, make brain cells get sufficient oxygen and nutrients, strengthen metabolism, change the imbalance of the cerebral cortex, deepen the inhibition process, and play a calming and sleeping role.

1.Cataracts caused by short-wave infrared rays.

Infrared rays are easy to penetrate into the transparent medium and reach the eye, the refractive interstitium is vascular, the heat dissipation performance is poor, and the adjacent uvea can absorb a large amount of radiation, so it is susceptible to damage and form cataracts. If infrared rays are concentrated in the macula, macular damage can occur. >>>More
