February is National Self-Check Month, a reminder to pay attention to the small signals your body sends before they become big problems. Doctors encourage regular self-checks, starting with your skin. Take a close look for anything unusual; moles that have changed color or shape, spots that darken, or wounds that refuse to heal. Other warning signs worth noting include unexplained weight loss, blood in your urine, and changes in digestion or bowel habits. These clues don’t always mean something serious, but they’re worth discussing with a healthcare provider.
Self-awareness also extends to everyday habits we rarely question, like how we sleep. Most of us pile up pillows for comfort, but if you’re prone to glaucoma, that habit may be worth reconsidering. Research published in the British Journal of Ophthalmology suggests that stacked pillows can alter neck position and compress the jugular vein. This may increase eye pressure, potentially damaging the optic nerve and raising the risk of glaucoma.
And what about that classic bedtime tip - warm milk to help you drift off? While it may feel soothing, a study in Frontiers in Psychology found that dairy could actually contribute to nightmares, especially for people with lactose intolerance. The discomfort caused by poor digestion may interfere with sleep quality and dream patterns.
The takeaway this month: tune in. Small observations about your body—and your habits—can make a meaningful difference in protecting your health.
