It's probably not new for most of you but
As a tibia lengthener 1.5 year post surgery I cant stress enough the importance of sleeping.

From my experience, having a good sleep, which is at least 7-8 hours straight, is a serious booster to healing and recovery.
Sadly I'm a very bad sleeper even prior to surgery. But when I do manage to sleep good, I can feel like something miraculous happened during the night, like a 2 months of healing was done. I can only speculate how faster my recovery had been if I could sleep good from the start.

Doing hard work at physiotherapy, walking, whatever it's all great, but during sleep some processes are going in that are probably work at a much much slower rate, if at any rate, during waking time.

So sleep tight
