Moist vs. Dry Heating Pads:
When shopping for a heating pad, you'll notice moist heat and dry heat options. Moist heating refers to an insert that can absorb water. The unit then heats the insert. Moist heat penetrates deeper into your tissues, so it may help with pulled muscles, cramps and other soft tissue issues.
Dry heat tends to last longer and is more effective on the surface; many prefer this for painful joints and sore vertebrae. Some people find dry heat easier to apply.
For the most part, using moist heat versus dry heat is a matter of personal preference. You may also find that your sore muscles respond better to moist heat, but your achy shoulder does better with dry heat. Many people choose one of each type of heating pad to keep on hand for when they need heat therapy.
Using a Heating Pad:
Many people are worried about accidentally falling asleep while using a heating pad. But almost every new heating pad features auto shut-off. With this feature, the heating pad automatically shuts off after two hours.
Try to limit a session to no more than 20 minutes at a time since a typical moist heating pad will cool off after this duration. Give yourself a 90-minute break between sessions with any type of heating pad.
Benefits of Heating Pads:
Heating pads do not require a doctor's prescription. You can use them along with an over-the-counter or prescription pain relief medication or muscle relaxant. Many physical therapists recommend using heating pads after doing exercises.
Some even qualify for reimbursement under Flexible Spending Accounts (FSAs). If you have an FSA card, you may be able to pay for qualifying products with it.
Heating pads don't take up a lot of space, so you can bring them with you when you travel. There are few side effects to using a heating pad, although it's a good idea to check with your doctor before starting any type of self-treatment at home for your pain.
Common Conditions:
Heating pads help with many short-term and long-term pain conditions. Back pain (particularly lower back pain) is a common complaint, and it's one of the leading reasons why people go to the doctor, especially among people who lift, bend, reach or pull a lot.
If you have a spinal disorder—such as a slipped or herniated disc—heating pads may help. Shoulder pain is also common, and it may be caused by arthritis, tendonitis or a tear to a ligament or tendon.
Applying heat may also reduce the pain of menstrual cramps, which is caused by powerful muscle contractions of the uterus. The cramping and pain is often worse in women with polycystic ovarian syndrome (PCOS) or endometriosis.
No matter the condition, your muscles can greatly benefit from heat treatment. If you have sore joints or sore muscles after an intense workout or prolonged activity, using heat helps restore blood flow to the damaged tissues. Many people find heat therapy helpful beginning 48 hours after an injury or surgery.
