Is it good for children to sleep with socks on at night?

Generally speaking, it is not advisable for children to sleep with socks on. Here's a detailed explanation:

Wearing socks that are too tight may affect blood circulation in the feet, leading to poor local circulation. Over time, this could negatively impact foot health and cause discomfort, thus affecting sleep quality. If the socks are made of non-breathable materials, they may also cause excessive sweating, leading to dry skin or other skin problems.

Children's feet contain numerous nerve endings. Going barefoot allows them to better sense external temperature and surface textures, which supports the development of tactile nerves. Wearing socks during sleep may limit this sensory stimulation, potentially hindering the child's sensory development. Therefore, it is generally not recommended for children to wear socks while sleeping.

In daily life, parents can use alternative methods to keep their child's feet warm, such as using a hot water bottle or dressing the child in appropriate pajamas and sleep sacks.
