Cold and Heat Therapy Are Free and Surprisingly Effective

Before reaching for pills, consider the two oldest remedies: cold and heat. A cold shower or ice pack reduces inflammation, eases acute pain, and can boost alertness. Heat — a warm bath, heating pad, or hot water bottle — relaxes muscles, improves circulation, and soothes chronic tension. The general rule: cold for fresh injuries and swelling, heat for stiffness and chronic aches. Neither costs anything, both are low-risk, and their effects are backed by solid evidence. They won't replace medical care for serious conditions, but for everyday discomfort, they're remarkably powerful.
