Understanding the Mechanism: How Deep Heat Works
Deep Heat is a topical pain reliever that creates a warming sensation on the skin to soothe underlying muscle and joint discomfort. Unlike passive heat from a heating pad, this effect is created by a chemical reaction involving counterirritants, such as methyl salicylate and menthol. These ingredients stimulate temperature-sensitive nerve endings in the skin, creating a cooling followed by a warming sensation that distracts the brain from the deeper pain signals. This process also causes vasodilation, which increases blood flow to the treated area. The rush of oxygenated blood and nutrients helps relax tight, sore muscles, and promotes the healing process.
Targeted Application for Common Ailments
Deep Heat products are designed for targeted, temporary relief. The specific application method depends on the product form you are using.
How to Apply Creams and Rubs
- Clean the Area: Ensure the skin is clean and dry before application.
- Dispense Sparingly: Apply a thin layer of cream or rub to the affected area. Start with a small amount to test skin sensitivity.
- Massage Gently: Massage the product gently into the skin until it is fully absorbed.
- Wash Your Hands: Wash your hands thoroughly immediately after application to prevent accidental contact with sensitive areas like the eyes or mouth.
Using Patches for Specific Areas
For back pain and joint stiffness, patches offer a convenient, long-lasting, and odourless option.
- Prep the Skin: Apply the patch to clean, dry skin.
- Affix the Patch: Remove the protective film and apply the patch directly over the painful area. For delicate or aging skin, it can be applied to clothing instead.
- Secure Properly: Ensure the patch is secure and avoid applying prolonged pressure against it.
Applying Deep Heat Spray
Sprays are ideal for hard-to-reach areas and quick application.
- Protect Your Face: Shield your face when spraying around the neck and shoulders.
- Spray from a Distance: Hold the can a safe distance away and spray directly onto the affected area.
- Wash Up: Remember to wash your hands after use.
Areas to Target for Relief
- Back: For lower and upper back pain, apply cream or use extra-large heat patches specifically designed to cover the lumbar area. For sciatica pain, apply heat to the lower back and pelvic area where the nerve roots originate.
- Neck and Shoulders: Gently massage a rub into the neck and shoulder complex or use specially designed patches for targeted relief.
- Knees: Apply a cream or use a patch directly to the knee joint to help with stiffness and arthritis pain.
- Thighs and Calves: For common leg muscle aches and strains, generously massage a heat rub into the quadriceps, hamstrings, and calf muscles.
Safety First: Where NOT to Apply Deep Heat
Following safety guidelines is critical to prevent skin irritation or burns.
- Broken or Irritated Skin: Never apply Deep Heat to cuts, scrapes, abrasions, or sunburned skin.
- Sensitive Areas: Avoid contact with eyes, nose, mouth, and genitals.
- Internal Use: Deep Heat is for external use only. If ingested, seek immediate medical attention.
- Children and Pregnant Women: Not suitable for children under 5 years old. Consult a doctor before use if you are pregnant, breastfeeding, or have certain health conditions like asthma.
- No Bandages: Do not cover the area with a tight bandage, as this can trap heat and increase the risk of side effects.
