When do you need a body warmer?

People who feel cold rarely feel it everywhere. Usually it is one spot: the lower back after a long day sitting, the shoulders in a draught, the stomach during period pain. Gloves and thicker jackets do not help with that – a targeted heat source does.

All models come from The HEAT Company and use the same reaction as the hand warmers: iron powder, activated carbon, salt and water oxidise in air and give off heat. The body warmer averages 51 °C with peaks up to 63 °C – separated by clothing, considerably less reaches the skin.

Adhesive pad, belt or emergency kit?

Three ways to bring the same heat to your body. Which one suits you depends less on the spot than on how often you need it.

Body warmer, 12 hours – the self-adhesive single-use pad. Stick it on your underwear, right over the tense spot. Flat, discreet, ready immediately. The cheapest way in.
Back warmer, 18 hours – the large-surface version for the lower back or shoulder area. Six hours more run time, more coverage. Available as a pack of three. Adhesive pads for neck and shoulder are in the heat patches category.
Heat belt, 12 hours – the reusable solution. Instead of an adhesive pad, a belt holds the heat element in place. The belt stays, only the pad is replaced. If you deal with back trouble regularly, this works out cheaper over time – and you can position the heat precisely without adhesive pulling at your skin.
Emergency kit with survival blanket – heat pads combined with a survival blanket, for the first aid bag or rucksack. Not meant for everyday use, but for the case where someone is getting cold and needs warmth fast.

What to look out for

First, frequency. For the occasional strain the adhesive pad is enough: tear open, stick on, done. If you need it regularly over weeks, the heat belt pays off – after that you only buy pads.

Second, run time. Six hours separate 12 from 18. That decides whether you have to replace one in the evening or stick on once in the morning and get through to the night.

Third, the layer between pad and skin. All adhesive versions go on clothing, never directly on skin. With steady heat you get used to the temperature and stop noticing it as too hot – that is exactly how irritation happens.

Who are body warmers for?

✓ Office work – a tense back after long hours sitting
✓ Outdoor work – construction, forestry, events
✓ Hunting and stand time – sitting still for hours in the cold
✓ Winter sports – warmth under the ski jacket
✓ First aid and preparedness – heat for someone getting cold

Frequently asked questions – body warmers

How long does a body warmer last?

The small adhesive pad lasts 12 hours, the large back warmer 18 hours, the heat element in the belt 12 hours. All reach full temperature after 5 to 10 minutes and cool down gradually at the end rather than stopping abruptly.

Heat patch or heat belt – which is better?

It depends on how often you need it. For occasional use the adhesive pad is enough. If you deal with tension regularly, the heat belt is the better choice: you only replace the pad, the belt stays, and you can position the heat precisely without adhesive pulling at your skin.

How hot does a body warmer get?

The body warmer averages 51 °C with peaks up to 63 °C. Because it sits on clothing with a layer of fabric in between, considerably less reaches the skin. The temperature cannot be adjusted – to reduce it, take the pad off for a while.

Can I stick body warmers directly on my skin?

No. They go on clothing, ideally on a close-fitting undershirt. Directly on skin, steady heat can cause irritation, because you get used to the temperature and stop noticing it as too hot. For persistent complaints, see a doctor or physiotherapist.

What is the emergency kit with survival blanket for?

For the first aid bag or rucksack. It combines heat pads with a survival blanket – the blanket holds body heat in, the pads add warmth from outside. Meant for situations where someone is getting cold and help is still some way off.
