Headaches after bathing or being in the cold are usually caused by sinus sensitivity or migraine triggers, not eye problems. Cold water or air can irritate the sinuses or set off migraines, leading to headaches. Since Sinarest helps her feel better, congestion or sensitivity to cold might be involved, but this does not confirm the exact cause. It is not always easy to say if it is only sinus or only migraine without a proper checkup. Pain around the forehead, cheeks, or nose with a heavy feeling may point to sinus issues. If the pain is on one side, throbbing, or comes with light sensitivity or nausea, it could be a migraine. A doctor can examine her and suggest treatment if needed. She can try to avoid cold triggers, use lukewarm water for bathing, and keep her head covered after a bath. Steam inhalation may help if her sinuses are involved. Keeping a regular sleep schedule, staying hydrated, and managing stress can also help prevent migraines. If her headaches happen often, are severe, or are getting worse, consulting a doctor can help find the cause and plan long-term care.
