Which measure will NOT help relieve pain?

Keeping lights on in the room is not a measure that typically contributes to pain relief. In fact, bright or harsh lighting can lead to discomfort and may exacerbate feelings of anxiety or stress, which can, in turn, heighten the perception of pain.

In a healthcare setting, it is often beneficial to create a calming environment that promotes relaxation. This can be achieved through dim lighting, which is more soothing and conducive to comfort. On the other hand, providing blankets helps to maintain body warmth, soft music can promote relaxation and distraction from pain, and a back massage can stimulate blood flow and provide physical relief, making these measures effective in managing pain. Thus, bright lights would be counterproductive in a pain management context.
