  • Sciatica: To treat the pain, it is recommended to apply dry heat, for which heat packs are ideal. By applying heat directly to a specific area, blood circulation is improved, which helps to reduce inflammation and pain.
  • Lower back pain: Applying heat through the microwavable heating pad relaxes the muscle and more blood reaches the area, which helps to reduce inflammation and neutralise pain receptors, so it is also highly recommended and useful for lower back pain.
  • Joint pain: Due to osteoarthritis or arthritis, the joints become stiff and cause severe pain. The application of heat with seed heat pads relieves the pain and improves blood circulation to the area, thus avoiding certain medications.
  • Muscle contractures: Intense physical activity or a wrong movement can cause small muscle contractures that are very painful and uncomfortable. When you apply heat with the seed pack, the muscle relaxes and the pain is relieved. Always use the heat when the area is not inflamed.
  • Colic and flatulence in babies: Heat mainly inhibits pain receptors, but also promotes blood circulation, helping to displace air and relieve swelling and discomfort caused by colic and bloating, especially in babies.
  • Menstrual pain: applying heat to the ovarian or kidney area helps blood flow better and turns off pain receptors. Heat packs are a great way to relieve menstrual cramps and regulate body temperature.
  • Before the massage: Before a relaxing massage, it is very practical to warm up the area to be treated. Therefore, apply the semen heat pack at least 10 minutes before the massage to relax the muscles, warm them up and experience greater pleasure.
  • Natural anti-inflammatory: To relieve inflammation after a blow, bruise or due to muscle atrophy, seed pillows are an excellent option. You should apply them cold to the painful area for 15 minutes and you will find that the swelling goes down.

How to use microwavable heating pads for pain relief?

Heat therapy

  • 1: Heat our seed pillow in the microwave on maximum power between 1:30 and 2 minutes, depending on the size.
  • 2: Place the pack on the painful area for 15-20 minutes. You will feel your muscles relax and the pain disappear.
  • 3: The pain disappears and we automatically feel better, we can repeat the process as many times as we want.

Cold therapy

  • 1: We chill our seed pillows in the freezer for about 2 hours before the cold treatment.
  • 2: Place the seed pillow on the area to be treated for about 12-15 minutes, you will feel the area relax due to the cold therapy.
  • 3: Thanks to the effect of the cold therapy, our pain and inflammation disappear. Apply 3 to 4 times a day for better effectiveness.

Best seeds for filling microwave heat packs

  • Flaxseed: Undoubtedly the best option, as they are small and adapt perfectly to any part of the body. They are very resistant to high temperatures and have an excellent shelf life for long periods of time, which are beneficial for health.
  • Clay balls: A highly recommended option and also natural as clay has very interesting thermal properties and can withstand heat for some time, its size is variable and we can choose the one that best suits our body.
  • Wheat seeds: Almost on the same level as flax seeds, as they are a good size both in length and thickness, they adapt to any part of the body and support heat perfectly, although they are less recommended due to less good preservation.
  • Cherry pits: Being relatively large, they do not conform well to the body, especially in smaller areas such as joints, etc. They are also quite hard pits that can put too much pressure on the painful area and damage it further.
  • Olive pits: As with cherry pits, they are quite uncomfortable in the lumbar region or on the back as olive pits are quite hard.
  • Millet seeds: This type of seed has the advantage of being small and fits very well on the part of the body to be treated. The problem is that they lose their heat quickly and have to be heated several times to have an effect.
  • Rice: This type of seed is less used than the previous ones, although it is never a bad idea to mention it. When using rice as a filler, be aware that the bag has an unpleasant smell and that small insects will settle in the grains if they are not used regularly.

F.A.Q: Frequently asked questions

Can microwavable heating pads be washed?

Of course they can be washed, but only the outer sleeve. All our models have two covers, one inner and one outer, so you can easily wash the outer cover of the heat pack without fear of getting the seeds and flowers on the inner cover wet. By simply removing the outer cover, you always have it clean and ready for use

As it is a 100% cotton fabric, there is no great mystery about how to wash it, as it is a fibre that is easy to handle and very resistant to both hand and machine washing. You can wash the cover in warm or cold water, but if the temperature is too high (above 60ºC / 140 °F) it may lose its colour and shrink a little; we recommend temperatures of no more than 40ºC (104 °F).

Why is lavender beneficial for health?

The great thing about seed pillows is that they contain lavender, the queen of aromatherapy, whose flowers contain an essential oil that is calming and relaxing. As the essential oil is volatile, it can be easily inhaled and we can benefit from its aroma and active ingredients

Aromatherapy, especially lavender, has been proven to help improve mood and complete relaxation. Thanks to the care that goes into every detail of the manufacturing process of the aromatic flower warming bags, we get a product of the highest quality, handmade and durable, so that we can enjoy it for years to come.

What are the risks and dangers of using a microwavable heat packs?

Comparing the risks of a seed pillow to those of the alternatives above, the risk of burns with the seed pillow is very low as it does not contain any electrical components or high temperature liquids. If you can judge the right temperature with your sense of cold and heat, the risk of burns is practically zero

But, for example, if you think of a diabetic person who does not have much sensitivity in the feet and hands, you do not have to worry because if you follow the recommendations for use, such as the heating times defined in each product, you will not have to worry because the heat that the seeds will hold will be sufficient to provide the warmth and the analgesic effect, and this heat will gradually decrease to be at room temperature about 25-40 minutes.

Are there any contraindications to the use of seed pillows?

It is always interesting to know when it is not advisable to use heat, because while it is true that it is a useful natural therapy for many conditions, there are also times when its use is contraindicated. For example, heat should not be applied to open wounds in acute inflammatory processes, such as sprains or trauma, as in these cases cold is indicated to lower the blood pressure in the area and reduce inflammation

If the person applying the heat to the body suffers from impaired sensitivity, this can be counterproductive as they will not notice if the heat is too strong and risk burning themselves. To avoid this, it is best to follow the instructions for each product and apply the hot and cold therapies for about 20-25 minutes. Heat should also not be applied to the abdomen of pregnant women, but it is possible to apply heat to the lower back without disadvantages.

What are the alternatives to heat packs and which is the best option?

One of the reasons for using heat packs is thermotherapy, which is theuse of heat for therapeutic purposes, especially for pain relief. In order for heat to provide the relief and help we need, and for it to be considered an effective remedy, it must be applied at a temperature higher than the physiological or natural temperature of our body, which is around 36-37ºC (96,8-98,6 °F). In order to benefit from thermotherapy, the product we use to apply heat to our body must be at least 40ºC (104 °F) or higher.
