What should a nurse advise a client to do to reduce pain at the onset of a migraine?

Advising a client to darken the lights is an effective strategy for reducing pain at the onset of a migraine. Migraines are often triggered or worsened by bright lights or glare, and many individuals experiencing a migraine find relief in a dark, quiet environment. Light sensitivity, known as photophobia, is a common symptom associated with migraines, and reducing light exposure can help alleviate the discomfort and intensity of the headache.

While other methods may offer some relief in different contexts or for different symptoms, they may not address the specific discomfort caused by light sensitivity that many migraine sufferers experience. For example, engaging in light physical activity could potentially exacerbate symptoms for some individuals. It's essential for clients to find what works best for them, but creating a dark and calm environment is a widely recommended approach for those facing migraines.
