The concept of keeping in good health in China's ancient medicine holds that "all diseases begin with cold, and cold begins with the soles of the feet. Nowadays, parents, especially the elderly, believe in this concept and will always take good care of their baby's feet and keep warm. Both the ancients and the present elders believe this view. That's because the ancients didn't know why feet felt cold most easily and their metabolism was slow, so they felt cold easily.
But for children, it is another matter. The hot weather in summer makes the baby's metabolism faster and makes them sweat. If you put socks on your baby, your baby's feet will always be covered, which will lead to breathing difficulties and even bacteria and infections. People regulate the temperature by sweating. If you still wear socks for your baby, it will be difficult for your baby to cool down. At that time, it was not "cold feet" but "sick fever", but premature babies had to wear socks.
Premature infants' thermoregulatory function is not well developed, their own heat is not enough, and their body temperature is easily lost. Wearing socks for the baby can keep warm at this time. The temperature around the baby should not be too low, or in hot summer, bring the baby into the air-conditioned room and put on a pair of socks, but the temperature of the air conditioner should not be too low. Socks are just tools to keep warm, not necessarily to keep warm. Wear socks when going out to play, but protect your baby's feet from small stones and bacteria.
In summer, you can choose loose and comfortable thin socks for protection. Not too tight, so as not to interfere with your blood circulation.
