Do people shed their skin while they are sleeping?
People don't shed skin like snakes and lizards do, we lose skin cells a little all the time. When we're asleep some rubs off against the bedclothes, when we're awake some rubs off against our regular clothse.
They will shed a lot while they are growing. When they have reached full size, they will shed less, but expect them to shed their skin two or three times a year. When they are shedding, it is ok to remove skin that is already hanging off, but do not pull skin from a bearded dragon's body. It can damage the new skin underneath and cause infections.
