With heat therapy and lavender flower aromatherapy, forget about painkillers and medications that have proven to be harmful to your long-term health, and switch to natural remedies that really work. Thousands of people are already benefiting from local heat and cold therapies for pain relief.

In heat

When heat is applied at a temperature of more than 40°C (104 °F), as is the case when the heat pack is heated in a microwave oven, heat receptors are activated, which in turn inhibit pain receptors - simple as that. It provides natural pain relief, anti-inflammation, muscle relaxation, general well-being, improved blood circulation and instant warmth.

In cold

Cold can be applied to injured areas to reduce swelling and prevent bruising. Oxygen is present in higher concentrations in cold environments. By applying the large heat pack, which has previously been chilled in the freezer, to the areas affected by the blows, the blood will circulate better and be enriched with more oxygen, allowing the muscle, joint or skin to recover faster and better.

F.A.Q: Frequently asked questions

How long does it need to be heated in the microwave or oven?

The classic hot water bottle in the shape of a bag filled with lavender seeds and flowers is one of the most popular models sold today, for those nostalgic for this model but with the added security of not burning yourself by spilling boiling water. To heat it in the microwave, place it on a clean plate and leave it at 800 W for about 2 minutes, shorter at 1000 W or higher. If you don't have a microwave at home, you can use an electric cooker, definitely not a gas cooker, to heat it at 125ºC (257ºF) for 10-15 minutes, but never leave the cooker out of sight for safety reasons.

How can I care for it to make it last longer and increase its lifespan?

As it is a handmade product made of 100% natural materials, it requires special care and maintenance. To extend its shelf life, it is advisable to warm the seed bag at least every 4-6 months when not in use so that the ingredients inside do not spoil over time and when not in use. A tip to ensure the seeds retain a higher calorific value is to microwave a glass of water with the pillow of seeds every 8-10 uses so that the seeds absorb the steam from the water as it heats up and rehydrates the seeds, ensuring a longer shelf life. Store in the box in a dry, dark place.

How long does the hot and cold microwave pad last?

This is undoubtedly the great advantage of this model, and if we want to sleep with the product, we have no danger because the heat gradually decreases during the night and is able to maintain its temperature through body heat, a pleasure to sleep warm and safe. When we apply it on our body at room temperature , the heat lasts about 25 to 40 minutes. In the cold, as soon as we take it out of the freezer, it stays cold for about 15-20 minutes, this also depends on the outside temperature. One point to consider is that you can use it without any kind of fabric on your skin, as it has a cotton cover and you don't run the risk of burning yourself in the cold.

Can the hot & cold pack be washed?

Of course you can wash it, but only the removable coloured fabric cover, because the white cover is responsible for the seeds and the lavender and if it gets wet we have to dispose of it. To keep it clean, always follow one simple tip: Don't wash it above 40 ºC (104 °F) and wash it separately the first time to avoid it staining other clothes.
