Overcome neck and shoulder tension or soothe painful cramps with this therapeutic heat pack made from eco-friendly, natural, sustainable materials which last.

Designed to particularly help with the sore neck and shoulders that come from stressful days or being hunched over whilst working-from-home, lum's adaptable heat pack can also be used to help ease aching muscles or cramps. Activate the heat pack by gently warming for up to 2 minutes in a microwave - it will stay warm for around an hour. If you prefer cold therapy, store in the freezer and use as a cold compress. You can choose to customise your heat pack with UK-grown lavender buds for an ultra-relaxing experience!

Heat the person (not the room)

Reducing our energy consumption is one of the key ways through which we can reduce our carbon footprint. With energy bills rising, it's never been more important to try and keep warm in a sustainable and efficient way. Your lum heat pack works like a traditional hot water bottle, helping you keep yourself warm without having to heat a whole flat or room with gas, electric or oil heating.

How to use

Relax and soothe your tense muscles by applying heat to boost circulation and blood flow to the affected area. Or reducce your heating bills by using a heat pack instead of central heating on chilly days!  Here are some instructions if using them for the first time: 

For heat therapy:
  1. Ensure the microwave turntable is clearn and rotating for even temperature distribution. Place a small mug of water in the microwave with the heat pack to help keep it moist.
  2. Microwave (800w) in 30-second increments for a maximum total of two minutes.
  3. Remove from the microwave and apply to the afflicted area. 
  4. Wait until completely cooled before re-heating. 
For cold therapy:
  1. Place heat-pack in a freezer-proof container or sealable bag. 
  2. Store in freezer for at least 30 minutes or until next desired use.
  3. Remove from the freezer container/bag and apply to the afflicted area.

Inspired by the Basking Shark

The basking shark is the second largest fish in the world, which can grow up to 12m in length. A gentle giant, they feed only on planktonic prey that they filter through their gaping jaw. Basking sharks are at a high risk of extinction due to historic overfishing, entanglement from nets and ropes, and rising sea temperatures (due to climate change) distrupting long-established mating patterns.
