Hot packs are a natural and relatively safe way to keep warm or relieve pain. You can buy a hot water pack at a drugstore or medical device store and it only takes a few minutes to prepare.
Steps
Pour water into the hot water bag

Choose a hot water pack. Regardless of the brand, hot water packs have the same design, consisting of a thick, flat bag, usually a rubber bag, and an outer sheath. Some have thicker covers in different materials, so choose the one that works best for you. Be sure to buy a pack with a cover, as you need some insulation between the pack and the skin.
- Before pouring hot water into the pack, you need to check that the pack is covered. The cover of the pack may get a little wet, but if you pour hot water into an unwrapped pack, the rubber may become too hot to handle.
Open the cover of the pack. Your ice pack is probably covered with a cover and has a stopper on top to prevent water from spilling out. Let’s start by opening the stopper to pour water into the bag.
- If there is still water in the bag, be sure to empty the old water. You need to make the most of the heat of the pack, so the cooled old water left in the bag will make the pack less effective.
Heat water. You can use hot water from the tap, but often the tap water isn’t hot enough to fill the pack. On the other hand, boiled water is too hot. You should try to use water with a temperature not exceeding 42 degrees Celsius.
- If using a kettle, you can bring the water to a boil and let it cool for a few minutes. That way, you’ll have hot water to use without getting hot enough to burn your skin.
- Water that is too hot can not only damage the skin, but also reduce the durability of the pack. The rubber material of the ice pack cannot withstand very hot water for a long time, so using hot water not exceeding 42 degrees Celsius will be the best way to increase the life of the pack.
- Each type of ice pack will have different temperature requirements, so you should read the product’s instructions carefully before using it.
Fill the pack about 2/3 full with hot water. This step requires careful handling; because of course you don’t want to get burned by hot water. If using a kettle, slowly pour water into the pack until it is about two-thirds full. If you’re using tap water, turn off the faucet when the water starts to get hot and catch the mouth of the pack in the faucet. Slowly turn the faucet back on so water doesn’t splash on your hands.

- Be sure to hold the ice pack around the neck of the bag to be sure. If you hold it by the body, the top of the pack can flip down before it’s full and cause hot water to spill out of the pack into your hand.
- You can wear gloves or other items to protect your hands, in case you accidentally spill water on your body. You can make it stand on its own by placing other objects around – so you can pour water into the pack without worrying about burning your hands.

Remove the pack from the faucet. When the pack is almost full (don’t fill the bag with water, as you need to leave a small space to push out the air, and the water-filled pack can easily overflow), turn off the faucet slowly. water, then carefully remove the pack, making sure not to let the water overflow.
- If using a kettle, you can put the kettle down while holding the pack upright with your other hand. Remember not to let the water in the bag overflow or tilt the pack.
Squeeze the air out of the pack. Place the ice pack upright with the bottom of the pack resting on a flat surface. Next, slowly squeeze the two sides of the pack to force the air out. Continue squeezing until you see the water rise to the top of the bag. [2] X Research Source
Screw the cap back on the pack. After you have pushed out all the air, you can re-screw the cap of the pack, making sure to tighten it tightly. Twist the cap of the pack until it can no longer be twisted, then try again by turning the pack upside down to see if any water comes out. [3] X Research Sources
Place the hot water pack on the area of skin that you want to apply. You can use an ice pack for pain relief or for warmth on a cold night. After you have poured hot water into the pack, put it on your bed or apply it to your skin for 20-30 minutes. It may take a few minutes for the pack to warm up, but as soon as you put the hot water in it has reached its highest temperature. [4] X Research Sources
- Make sure not to leave the compress on the skin for more than 30 minutes. Prolonged exposure to direct heat can harm you, so try to stay as safe as possible. If you apply heat to relieve pain but still have pain, stop applying it after 30 minutes, wait about 10 minutes, and then apply it again.
- If you put the pack in bed, leave it under the blanket for about 20-30 minutes before getting into bed. When you go to bed, you should take out the pack and pour out the hot water. If you leave an ice pack on your bed while you sleep, you run the risk of scalding or burning the bed sheets.
Empty the water after using the pack. Empty the water in the pack after it has cooled down and hang the pack upside down to dry, remembering to open the cap. Before using the pack again, you should check it for leaks or damage by filling it with cold water.
- Do not expose the pack to fluctuating temperatures (such as above the stove), under the sink, or in direct sunlight, as temperature changes can degrade the pack.

Soothes menstrual pain. Hot water packs are commonly used to ease menstrual cramps. Heat can block pain signals from reaching the brain by stimulating heat receptors in the painful area. These receptors block the recognition of pain-causing chemical signals in the body. If you have menstrual cramps, you can pour hot water into a pack and place it on your lower abdomen for about 30 minutes. [5] X Research Sources
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/9/96/Fill-a-Hot-Water-Bottle-Step-11-Version-2.jpg/v4-460px-Fill- a-Hot-Water-Bottle-Step-11-Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/9/96/Fill-a-Hot-Water- Bottle-Step-11-Version-2.jpg/v4-728px-Fill-a-Hot-Water-Bottle-Step-11-Version-2.jpg”,”smallWidth”:460,”smallHeight”:259,” bigWidth”:728,”bigHeight”:410,”licensing”:”<div class=”mw-parser-output”></div>”}
Relieve back pain and other forms of pain. If you have back pain, joint pain, or muscle pain, a hot water pack will often help relieve stress. Similar to menstrual cramps, heat on the painful area blocks pain signals from reaching the brain. It also helps stimulate blood circulation to transport nutrients to help the body heal to the painful area. [6] X Research Sources
- Many times, a combination of hot and cold treatments can also help relieve muscle pain. The contrast between hot and cold temperatures stimulates and produces strong sensations without much movement, and this has an analgesic effect. You can just use hot water or alternately apply cold for a few minutes, then apply heat to the painful area. [7] X Research Sources

Headache cure. Heat can help relieve pain and muscle tension that can cause headaches. You can place a hot water pack on your forehead, temples, or neck. Try a few places to see where the compress works best, then apply it there for 20-30 minutes or until the pain begins to subside. [8] X Research Sources

Warm the bed. On cold winter nights, a hot water pack can help keep your feet or body warm. Place an ice pack at the end of the bed near your feet or under a blanket near your bed to warm it up. Hot water packs are also helpful if you are sick and your body temperature changes frequently. [9] X Research Source
Warning
- When using a hot water pack, you should follow safety instructions to avoid injuring yourself or others.
- Do not put pressure on the pack while it is holding hot water. For example, do not sit or lie on the ice pack. If you need a compress on your back, try lying on your stomach or side. You can also place an ice pack on the painful area and wrap it around your body with a cloth to keep it in place.
- Avoid using ice packs on young children or infants, as they can be too hot for a child’s skin.
- If you have sensitive skin, be very careful when using hot water packs. Try starting with the lowest temperature, then gradually increase it if possible.
- Never use a hot water pack if you suspect a leak or damage. Always test with cold water first, and if in doubt don’t try. Buy a new ice pack if you feel something is wrong.
- Splashing tap water on an ice pack can damage the pack faster because of the chemicals in it. If you want to preserve the durability of the pack, try using purified water instead of tap water. [10] X Research Source
- Some hot water packs can be microwaved, but you should always check the packaging first. Many ice packs should not be heated in the microwave or on the stove.
