Baby exposure to blue light has no effect on the human body. Blue light is a natural light, its spectrum is a little different from the usual exposure to daylight, but there is no stimulation to the human body. In case of drowsiness, it is recommended to take the child’s temperature or observe if there are other symptoms that may be caused by other reasons. You can also stop the blue light exposure to see if it improves. During this period, you should also pay attention to the baby’s diet and bowel movements, if there is anorexia or loose stools, it is likely that the abnormalities in the stomach and intestines are the cause, so you can use digestive drugs to relieve. If the fever is confirmed, the fever should be reduced in a timely manner, and the drowsiness should be relieved when the physical symptoms are improved.
