Sleep is essential for survival, and children need more of it than adults to support their physical and mental development. Infants have five times more REM sleep than adults, which is necessary for processing the day's events and storing new memories. Babies' brains are constantly taking in new information and experiences, so they need more sleep to process and retain all of this new knowledge. Additionally, healthy sleep patterns help children maintain a healthy weight and reduce the risk of obesity and other health issues.

Infants have 5 times more REM sleep than adults, which helps them process new memories
Infants' brains are constantly taking in new and fascinating information, and they need more sleep to help them process it all. They also need more sleep to support their physical and mental development. Sleep allows the body to repair cells and release growth hormones that help regenerate bones, tissue, and muscles.
Additionally, healthy sleep patterns in children can help maintain a healthy weight and reduce the risk of obesity and other physical health issues. Sleep is necessary for survival, and a lack of quality sleep can lead to behavioural problems at school.

Sleep is necessary for physical and mental development in children
Babies have five times more REM sleep than adults (8 hours versus 1.5). This gives them enough time to sift through all the day’s chaotic happenings to figure out which new memories to file away and which to forget. Adults probably need much less REM sleep because our lives are pretty routine. Most of the things we encounter each day are either not new to us or just too trivial to remember. But for babies, everything is new and fascinating. Their brains quickly fill to the brim with all the cool things they want to remember. Unlike adults, who first enter restorative sleep before we move on to REM, young kids dive immediately into REM to process their inbox of memories.

Sleep helps children maintain a healthy weight and reduces the risk of obesity
Sleep plays a crucial role in helping children maintain a healthy weight and reducing their risk of obesity. Children need more sleep than adults because they are growing and developing both physically and mentally. Sleep is necessary for survival, as it allows the body to repair cells and regenerate bones, tissue, and muscles. During sleep, the body releases growth hormones that are essential for healthy development.
Infants have five times more REM sleep than adults. This is because they are processing and making sense of the many new experiences and memories they encounter each day. Their brains are rapidly taking in and trying to remember a vast array of new information.
Unlike adults, who first enter restorative sleep before reaching REM, young children dive immediately into REM sleep. This is why infants need to nap every few hours. A single adult sleep cycle lasts 90 minutes, while a child's sleep cycle is much shorter, zipping through light and deep sleep more rapidly.
The importance of sleep for children's health cannot be overstated. Adequate sleep helps children maintain a healthy weight and reduces the risk of obesity. Children who don't get enough quality sleep are also more likely to experience behavioural problems at school. Therefore, it is essential to prioritize healthy sleep patterns for children to ensure their overall well-being.
