Infrared radiation has certain effects on pregnant women, specifically in the following areas: First, it can interfere with the immune system of pregnant women, because infrared radiation is an electromagnetic wave that can destroy lymphocytes and plasma cells in the immune system of pregnant women, and can also interfere with lymphoid organs, such as the thymus gland and bone marrow, thus causing adverse effects on the immune function of pregnant women. Second, it can affect the digestive system of pregnant women, because infrared rays can penetrate the human skin and enter the gastrointestinal tract of pregnant women, thus destroying the normal digestive function and secretion function of the gastrointestinal tract, which may lead to indigestion, nausea and anorexia. Third, it will interfere with the nervous system of pregnant women, because the infrared ray is relatively strong, can destroy the nerve cells of women, which leads to memory loss, drowsiness, coma and other neurological symptoms.
