How To Choose The Best Microwave Heating Pad For Back?
How Large Should A Microwave Heating Pad Be To Reach A High Effect For Your Back Pain?
Microwavable heating pads range in sizes from small to extra-large models, but you should choose one based on your needs and requirements. For instance, if you want to put your heating pad over your back, a bigger size is a better consideration. A larger size works better for different uses and purposes.
Is The Flexibility Of A Heating Pad For Back Important? Yes. The back isn't an even surface, so a flexible heating pad can contour the target area to transfer heat to your back better, raising the heating pad's effect.
What Is The Best Filling For Your Back?
Lava Sand
This is a type of legal mined sand that can absorb and keep heat very well, especially it’s durable and comfortable with an affordable price.
Lava sand is pretty safe because it won't burn you even when your fingers touch the heating pad after taking it out of the microwave. But, this type of heating pad is still warm enough for you, even though it can keep a continual temperature longer than other materials.
While it's straightforward for other materials to build up mold, bugs and rot, the lava sand doesn't have this problem. The latter is a mineral that will never go bad and attract creepy crawlies.
This type of sand is pretty heavy, so it can provide people with menstrual cramping and other pains a certain amount of pressure to relieve. Plus, it is just heavy enough to contour around the parts of your body without being bumpy.
Flax Seed
Flax seed is a seed from a flax plant. Though it can't keep heat as long as corn, wheat, and barley, it won't burn you when touching the pad that is taken out of the microwave. In particular, this filling can maintain a consistent heat compared to other fillers.
Even when heating the flaxseed many times, it won't emit the burning smell. However, this type of seed will attract weevils and other cupboard pests.
Thanks to the small size of flax seeds, they can contour your body better. This seed is lightweight, so it can't provide you with a certain amount of pressure like the lava sand.
If you heat these seeds too many times, they will burn. Therefore, you need to replace them periodically.
Walnut Shells
Walnut shells are pulverized walnut shells.
Although after heating, it's hot to touch walnut shells, they won't burn your skin. You need to spend a short time cooling them enough before using. And its warming time can be maintained within 10 minutes. This is a kind of food, so there is no need to worry about rot and bug problems.
These pulverized walnut shells are small pieces, so they can perfectly contour to your body and offer pressure. Although it is heavier and denser than the flax seeds, it is not as heavy as lava sand.
There is a smell but it is an earthy odor like walnut smell. So, it's not bad. After heating, this smell won't increase.
Wheat Berries
Wheat berries are a type of unprocessed wheat. They just removed the outer hull to last longer. They can keep heat very well, but it is very hot after taking them out of the microwave. Thus, it's pretty hot to use immediately even if you wrap up in a blanket or a dish towel. If you want to use it, wait for at least 5 minutes. This filling material can maintain the heat for around 15 minutes.
Thanks to their dense and dark features, you can reheat them many times without burning much. Don't let them be exposed to moisture. If not, they can go bad and rot.
These things can't contour your body as effective as small grains, so its comfort level is not too high. But, they can offer you a certain amount of pressure.
This filling material comes with a faint earthy smell that won't rise unless they are overheated and burnt.
Pearl Barley
Pearl barley is barley grains with the outer hull and the removed barn.
Like the wheat berries, the pearly barley is also too hot to touch after taking it out of the microwave. Wait for 5 minutes before using it, but it can keep a comfortable temperature for over 25 minutes.
These things are small grains, so they can contour your body to heat perfectly.
Without being heated, it won't create any smell. However, it will smell when being burnt.
Steel-Cut Oats (Irish Oats)
They are cereal grains or hulled kernels which are chopped into small pieces.
After first removing irish oats from the microwave, it's still hot and uncomfortable to touch, but this filling material can retain pretty well (not good as wheat, pearly barley, and walnut shells).
These small pieces can contour your body more and offer adequate pressure to you. Its smell is the same as the traditional oatmeal.
Corn Kernels
They are dried corn, but not the same version of popcorn. You don't have to worry about burnt popcorn when heating the heating pads. They are used as animal feed, especially bird food.
Compared to other types, this filler performs poorer, even its heating time is also shorter. Besides, they have many signs of deformity, mold, and rot.
The corn pieces have an enormous size, so they can't contour your body well, especially it's more bumpy, and bulkier than others.
Before heating, the corn has a faint dusty corn smell on the cob. And this smell will be stronger when being heated longer.
Rice
Though rice is a popular food, it is not good to use as a filling for a heating pad.
Its heat retention is good and the heating time is pretty long, about 25 minutes. But, it's very hot when first removed from the microwave, requiring you to wait for 5-10 minutes before using.
Though the rice is smaller and heavier than the corn, it's pretty bulky.
After heating a few times, you can easily recognize a burning smell.
Cherry Pits
Cherry pits take up to 10 minutes to wait for cooling.
When heating, there is not any sign of burning. In particular, although they do not rot and mold, it's easy to break.
Because of the large round size and lightweight density, they don't perform well with zero pressure.
Clay Beads
Clay beads don't retain heat well since they are large and round, and lightweight and its heating time just lasts about 5 minutes.
Because of the clay, this filling doesn't mold, rot, and attract pests. Thanks to the low heat retention, even when you heat it many times, it won't burn.
