Hot day? You may notice your fingers swelling. Depending on the temperature, pregnancy, a change in weight, or even bone growth, fingers can fluctuate in size. Whereas our bodies adapt to reflect our environments, a ring's diameter remains constant. As Lewis Nelson, MD explains to Health, "As the finger swells, the ring becomes a restrictive band," adding, "[the ring] can cut off blood supply to the finger." When your finger is cut off from blood for too long, a simple mishap can become dangerous.
Fortunately, there are plenty of at-home solutions for wedged rings. Start by finding a lubricant, like a hand lotion, Vaseline, or olive oil, and apply a small amount to your ring finger. Keep in mind that slathering on too much will make it hard to grip the ring with your free hand. Believe it or not, in these cases, Windex is the perfect solution (via Athletico). It will reduce friction between the skin and metal, but it won't make the surface of the ring too slippery. It may also help to raise your hand or run it under cold water, encouraging the swelling to go down before you start.
