Advantages and benefits of the microwavable heat pack for legs

The heat pillow allows it to be placed on specific parts of the body, e.g. the lumbar area, the neck area, the feet, to safely warm beds or cots in winter without leaking electrical components or hot liquids, as can happen with electric blankets or water bottles.

With heat therapy and lavender flower aromatherapy, forget 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 more than 40°C (104 °F), as it is when the heat pack is heated in a microwave, heat receptors are activated, which in turn inhibit pain receptors - it's as 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. Applying the heating pad, which has previously been chilled in the freezer, to the areas affected by the blows will allow the blood to 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 take to heat in the microwave or oven?

This model can be heated for about 1.5 hours at 800 W, but the time is shorter at 1000 W and above. This depends very much on your microwave. We recommend that you choose a shorter time the first few times you use it and increase the time until you reach the desired temperature. If you don't have a microwave oven, this is a good alternative. Always use an electric oven and heat it at 125 ºC (257 °F) for 10-15 minutes, checking the oven constantly. Do not use a gas cooker.

How can I care for it to make it last longer and extend its shelf life?

The seed cushion is a purely natural product, we do not use any synthetic materials or ingredients, so it is necessary to take care of it. We recommend heating it up in the microwave every 2-3 months when not in use so that the seeds and lavender flowers do not spoil. It is advisable to rehydrate the seeds every 8-10 times by placing a container of water in the microwave or oven with the bag to create steam which moistens the seeds, thus extending their shelf life. You can store them in the box in a dry, dark place.

How long will the cushion filled with hot or cold seeds last?

Believe it or not, if you use it to warm up the bed, the heat can last almost all night, although usually when applied to any part of the body, the heat gradually wears off and lasts for about 25-30 minutes, which is more than enough to relieve any kind of pain. If it is cold, once it is taken out of the freezer it will stay cold for about 15-20 minutes, this depends on the outside temperature. A positive point is that you can use it directly on your skin as it has a cotton cover and there is no risk of cold burns.

Can the thermal seed pillow be washed?

Yes, of course it can. It should be noted that only the outer cover, which is printed and coloured, can be washed. As it is a 100% cotton fabric, it is very temperature resistant, but care should be taken not to wash it above 40°C (104 °F). It is also recommended to wash it separately from other garments, especially the first time, to avoid staining other garments.

What do I get when I buy the heat pack?

All our models come with instructions and a beautiful box, perfect for gifting. We often want to give a useful, beautiful and original gift. The knee and calf heating pads filled with lavender flowers is the best way to surprise your loved ones.
