This Halfsize premium hot and cold pack  – Ideally use it cold from the freezer for pain, swelling, bruises or sprains.

Use heat for muscle pain or stiffness.

How does this hot and cold pack work?

Cold therapy is also known as cryotherapy. It works by reducing blood flow to a particular area, which can significantly reduce inflammation that causes pain, especially around a joint or a tendon. It can temporarily reduce nerve activity, and in the meantime relieve pain.

Hot therapy by adding heat to the area creates an opposite effect, opening the blood vessels up and increasing blood flow through injured tissue.

  • Often, heat therapy is most beneficial when used for a good amount of time, unlike cold therapy which needs to be limited.
  • Relaxes tight muscles, causing tissues to relax.
  • Decreases pain caused by muscle tension or spasms.
  • Causes vasodilatation of the blood vessels, which increases circulation to the area.

Increased circulation to your injured body part helps bring in nutrients, oxygen, and cells that promote healing. This increased circulation can also wash away metabolic waste materials that may be gathered around your injured body site.


Cold Therapy Benefits

  • Pain Relief – Cold packs are particularly effective at reducing swelling and numbing pain. An injury swells because fluid leaks from blood vessels; cold causes vessels to constrict, reducing them tendency to ooze. The less fluid that leaks from blood vessels, the less swelling results. Cold packs for pain and swelling caused by bumps, bruises and sprains. Icing by pack will reduce internal bleeding as well.
  • Ease muscle spasm – Aid muscle relaxation post-injury.
  • Cooling effect – Reduce fever or cool down on a hot day.
  • Cold also eases inflammation and muscle spasms.
  • The sooner you apply a cold pack to a sprain or strain, the sooner it can do its job reducing pain and swelling. For chronic problems. such as low back pain or muscle spasms, ice whenever the symptoms start up.

Applications for Use

  • Wipe all moisture from the pack before returning to store in freezer.
  • Lay the pack flat for storage in the freezer. Packs will stay soft, even at freezer temperature.
  • Store in freezer when not in use.
  • Packs are for external use only and are reusable.
  • Discard if punctured or leaking.


  • Do not sit, lie, or sleep on the pack as breakage/leakage may occur.
  • If you have cardiovascular, heart disease, diabetes, or blood vessel disorders such as vasculitis or Raynauds disease, consult your doctor before use.
  • Individuals with circulatory issues should consult a physician before use.
  • If contents are swallowed, drink several glasses of water and consul doctor immediately.
  • Constantly monitor application to avoid skin irritation. If you’re not careful, cold therapy applied for too long or too directly can result in damage skin, tissue, or nerve damage. So always prepare to wrap your cold pack in a towel or our terry covers  ( see our tery covers page)  in appropriate sizes. 
  • If cold therapy hasn’t helped an injury or swelling within 48 hours, call your doctor.


Hot Therapy Benefits

Heat can increase blood flow and circulation to your injured body that helps bring in nutrients, oxygen, and cells that promote healing. This increased circulation can also wash away metabolic waste materials that may be gathered around your injured body site.

Its help restore movement to injured tissue. Warmth can also reduce joint stiffness, pain, and muscle spasms. As with cold packs, heat packs have a role in easing pain from both acute and chronic injuries, such as sprains, strains, muscle spasms, whiplash, and arthritis. Doctors often suggest using cold packs for the first day or two, and then switching to heat if the symptoms persist or become more chronic.

  • Pain relief – applying heat can relieve discomfort in the area of pain. It causes vasodilatation of the blood vessels, which increases circulation to the area.
  • Ease joint stiffness – improve flexibility by adding heat to your limbs/joints.
  • Rapid recovery – increasing blood flow promotes healing of damaged tissue.
  • Relaxation – heat therapy soothes and can help alleviate daily stress/anxiety. Relaxes tight muscles, causing tissues to relax.
  • To relieve muscle aches, stiffness, tension, and cramps by heating the pack within minutes. Minor stiffness or tension can often be relieved with only about 20 minutes of heat therapy. Moderate to severe pain can benefit from longer sessions of heat therapy like warm bath, lasting between 30 minutes and two hours.

Applications for Use

  • Simply microwave the gel pack and apply to the affected area.
  • Heating time is based on 800W microwave or its equivalent, this will be 1.5 to 2 minutes in general. Adjust heating times accordingly to suit the power of your microwave.
  • Monitor the gel pack whilst heating. If you observe swelling of the pack, turn off microwave immediately and wait for swelling to subside.

Although you may feel tempted to apply the soothing warmth of a heat pack immediately following an injury, resist the urge. You should treat any new injury with cold for a couple of days before switching to heat. Heat actually may do more damage than good until most of the swelling is gone.


  • Heat therapy should utilize “warm” temperatures instead of “hot” ones. If you use heat that’s too hot, you can burn the skin. If you have an infection and use heat therapy, there is a chance that the heat therapy could increase the risk of the infection spreading.
  • Heat applied directly to a local area, like with heating packs, should not be used for more than 20 minutes at a time.
  • If you experience increased swelling, stop the treatment immediately.
  • Do not sit, lean against or lie on the gel pack as breakage/leakage may occur.
  • Always heat from room temperature – never from frozen.
  • Microwave the gel pack only, never the fabric cover/wrap.
  • If heat therapy hasn’t helped lessen any pain or discomfort after a week, or the pain increases within a few days,  consult doctor.
