‘Children grow taller while they sleep‘ – an US research study says.

In this study, sensors are put into the leg bones of baby lambs to test when growth happens. They continuously measured the bone length every 167 seconds for around three weeks. They observed at least 90% of the bone growth when they were asleep or resting.

They observed bone growth only when the animals were lying down. Also, almost no growth occurs when they are standing or moving around. The scientists believe that the same is true in humans. They say this is the reason why children get growing pains at night.

The growth in an animal normally is linked to growth plates – the bones involved with growth. When an animal is at rest, pressure on growth plates will be eased and it allows them to elongate.

Growth plates are like springs and during standing and walking they experience compression and tension. When the animal lies down or sleeps, these pains are eased and they resume growing.
