Friends coming to Harbin from southern China, are you always worried about your hands and feet freezing like ice blocks? Hand warmers are definitely a lifesaver, but using them incorrectly will waste their warmth. Today I’m sharing the practical tips I learned from my own mistakes—be sure to save this post!
Choose the Right Type of Hand Warmer to Avoid Pitfalls
First, you need to distinguish between two types of hand warmers: one is the common heating patch, which generates heat as soon as you tear the package, with a mild temperature that won’t burn your skin, suitable for sticking on clothes; the other is heating insoles, which are designed to be used with shoes and can generate heat continuously for 10-12 hours, a must-have for people with cold feet. All heating patches and insoles sold at Ice City Warm Sun are brand-new. When choosing, avoid overly cheap ones—they may get too hot and leave red marks. We recommend only the styles we’ve tested to be safe and non-burning, so you can use them with confidence.
Stick Them in the Right Spots for Maximum Effect
Many people stick them directly on their skin, which is a big mistake! They must be attached to the outside of close-fitting clothing, otherwise you risk burns. Where exactly to stick them? First, core warmth areas: lower back, abdomen, and upper back—warm these spots and your whole body will feel toasty. Second, easy-to-freeze areas: stick one on the inside of your down jacket’s hood to keep your ears warm; stick one in your gloves to prevent stiff fingers; tuck heating insoles into your snow boots to keep your soles warm, so you won’t feel cold even after a full day of walking. Never stick them on joints or areas with many blood vessels—this can cause low-temperature burns. I once stuck one on my knee and ended up with a small red patch that hurt for days.
Use Them for the Right Duration to Avoid Waste
Most heating patches generate heat for 6-8 hours, so it’s best to stick them 1 hour before you head out—they’ll warm up gradually and you’ll feel cozy as soon as you arrive in Harbin. For a full day of activities, 2 patches are enough; don’t use more, or you’ll feel overheated. If you have leftover patches when you return to the hotel at night, be sure to peel them off—don’t keep them on, as their temperature will drop significantly by the next day, making them less effective for future use. The 12-piece set from Ice City Warm Sun includes heating patches; if you’re worried about not having enough, you can also buy them separately—all are brand-new, so you don’t have to carry a big pack with you, saving luggage space.
By the way, small issues like exchanging hand warmers for the right size don’t have to be stressful.
