Freezer burn

Freezer burn, as it is known throughout the UNSC and it's colonies, is an injury caused from cryopreservation in the Cryo-chambers of UNSC ships and locals. During the freezing and resuscitation process, cloth or other materials, bandages for example, next to or against the skin causes cellular damage. This results in large welts or rashes on the covered areas, described as a making the skin "blistered and raw". Most UNSC personnel are stored in cryo either naked to avoid freezer burn, or clothed and willing to endure the various injuries. Spartans, for example, can be stored in cryo-preservation fully clad in MJOLNIR armor without the effects dulling their combat performance. It is not known if this is because they simply ignore the injury, or if the advanced materials mean that they do not suffer from the effects. Though the latter is likely not the case, as the Master Chief was noted for not having freezer burn after being woken from cryo-sleep, suggesting that it is possible occurrence.
