But the pressurized gloves in a pressurized spacesuit make it very difficult, and often painful, for astronauts to grasp objects during an EVA, which can last up to eight hours each day. Not surprisingly, the most common type of injury reported by astronauts involved in EVA work is hand-related, including a condition known as fingernail delamination, in which the nail completely detaches from the nail bed.
