With the recent temperature difference, babies are prone to colds and fevers, what should parents do if their babies have a fever? A baby’s basal body temperature is 36.9℃ to 37.5℃. Generally, the axillary temperature of 37.5℃- 38℃ is called hypothermia. For most babies over 3 months of age and adults, fever itself is not dangerous and does not burn the head. Therefore, if a baby with an axillary temperature of 38.5°C or less is in good spirits and is not affected by activities such as playing, there is no need to use medication to treat the fever. You can try physical cooling first. There are three methods of physical cooling 1. Take a warm bath to achieve the purpose of whole body heat dissipation by way of bathing. When taking a bath, the recommended water temperature is 35℃ to 37℃. Also pay attention to adjust the temperature of the bathroom and other rooms, do not make too much difference between the two. If the temperature of other rooms is much lower than the bathroom temperature, after the shower, to dry and then out of the bathroom. 2, use a warm wet towel to wipe the body. The temperature of the towel is best controlled at about 37 ℃. Use a warm wet towel to wipe the forehead, neck, armpits and extremities and other parts. Towel wipe the body cooling principle is to let the skin vascular expansion, so that the heat generated in his body in a timely manner, and wipe the body with a warm wet towel, the water stained on the body evaporates, will also take away part of the heat. 3, less wear less cover less wrap. Remember not to dress your baby too much to cover too tightly. 4, more than 6 months old baby fever should remember to drink more water. The process of water excretion can accelerate the discharge of heat from the body. But be sure to drink a small number of times, do not drink too much at once, otherwise it will increase the burden on the kidneys. Some babies may not like to drink plain water, which may be related to the usual habits given by parents. At this point, parents have to think of ways. For small babies, parents can use a medicinal dropper, like feeding medicine to feed water, insert the dropper into the baby’s mouth, squeeze water into it, feed a small amount of times, although parents work harder, but can ensure that the water is fed to the baby in a timely manner. Encourage older babies to drink more water, you can play games with them while drinking water, or play the game of Cheers with him, or play the game of whoever drinks more with him wins. Babies are very receptive to your suggestions in a fun game. Fever-reducing medication is recommended for patients with axillary temperatures above 38.5°C. The main purpose is to relieve the discomfort caused by the fever to the baby so that he can eat and sleep normally, get enough energy to fight the disease and maintain his strength. The safe and affordable fever reducers that are widely used worldwide and recommended by the World Health Organization are two oral medications: acetaminophen and ibuprofen.
