Can bacteria die from exposure to the sun?

Bacteria are everywhere in our daily lives. There are many ways to kill bacteria. For example, the sun can kill bacteria. This is because the sun contains ultraviolet rays, which are very good at killing bacteria. We can usually buy ultraviolet lamps, which can kill some bacteria in the air and indoors. They also have a good killing effect on bacteria on clothes.

Sunlight contains ultraviolet rays, so it can kill bacteria on the surface of clothes to a certain extent. However, it should be noted that due to the high frequency of ultraviolet rays, their penetration is very poor, so thicker clothes should be sterilized using high temperature methods.

How to prevent children from getting skin diseases

1. To prevent prickly heat, do not apply "Ten Drops of Water" directly

According to dermatologists, in summer, the outside temperature rises and the humidity is high. The baby's head, face, chest, back, armpits and other places are prone to small blisters and papules due to poor sweating. The itchiness makes the baby very uncomfortable. This is the most common prickly heat in summer.

To reduce the risk of prickly heat in babies, first choose a cool, ventilated place for them to play to avoid excessive sweating. If you sweat a lot, it is best to wipe it off with a soft towel as soon as possible to allow the sweat to evaporate better. Dress your baby in loose, breathable, water-absorbent cotton and linen clothes, and change wet clothes in time. Turn your baby over more often while he's asleep. Avoid washing with very hot water and soap. Some parents think that Shi Di Shui can clear away heat and detoxify, so they apply it on their baby's skin. However, Shi Di Shui is not a medicine for external use. It contains ingredients such as chili pepper, and external use may irritate the baby's delicate skin.

There are many kinds of mosquitoes in the summer. Adults may only have a little redness and swelling after being bitten, but babies' skin tolerance is not that good, so the rash reaction after being bitten is larger than that of adults, especially in exposed areas of the head, face and limbs. Some may develop papules, erythema or even obvious edema and ecchymosis, which makes parents feel distressed.

The best way to prevent insect bite dermatitis is to equip your baby's bed and stroller with mosquito nets, gauze curtains or other things that can keep out mosquitoes. In addition, applying mosquito repellent to your baby's exposed skin when going out, and wearing loose long sleeves and trousers made of thin cotton can also reduce the chance of mosquito bites. If infection occurs at the site of the bite or the baby has a fever, it is best to go to the hospital immediately for a doctor's diagnosis.

Impetigo, also known as impetigo, is a skin disease that young children are very prone to in summer. It is a bacterial infection. If the baby has skin problems such as prickly heat and scratches it with dirty hands, these circles of epidermal ulcers will appear on the body. This type of sore is contagious and will grow more and more. Some parents panic when they see sores all over their baby's body and don't know what to do. Director Liu said that there is no need to worry too much about this skin disease, because it will get better after using some external anti-inflammatory drugs, and it will not leave scars in the future. However, it takes a longer time to heal than other skin diseases. Parents should be patient and not run to the hospital again and again, which not only wastes time but also increases the chance of the baby contracting other diseases.

To reduce the chance of contracting impetigo, in addition to not playing with sick children, you should also choose a good place to play outdoors. There are more mosquitoes in gardens, grassy areas or humid places, so you should try to avoid going there as much as possible. Babies should choose bright, dry and clean places to play, and these three conditions should also be met at home to prevent this skin disease from being contracted at home.
