Frequently Asked Questions (FAQ)

Here you will find answers to some of the questions we often hear.

Are there any side effects of laser therapy?

No, there are usually no side effects with laser therapy. It is very gentle and completely painless. However, you should protect your eyes, as the light is very strong. Protective glasses are included with all our lasers. We recommend that you wear them if you use the laser near your eyes.

Does laser therapy hurt?

Laser therapy is completely painless. You will typically feel a slight tingling in the skin and muscles, but there is no pain associated with laser therapy.

How does laser therapy work?

Laser therapy works by sending low-energy laser light into the body, which penetrates the skin, muscles, and joints, stimulating the cells to heal and function better – without damaging the tissue. Here's what happens in the body:

1. The cells receive more energy (ATP)
   • The light affects the mitochondria in the cells → they produce more ATP (the cell's "fuel")
   • More energy = faster repair and better function

2. Reduces inflammation and swelling
   • LLLT reduces the body's inflammatory response → less pain, swelling, and redness

3. Increases blood circulation
   • More blood = more oxygen and nutrients to the area → better healing and less muscle tension

4. Pain relief
   • The light can block certain pain signals in the nerves and release endorphins (the body's natural painkiller)

In short: laser therapy works by:

• Increasing cell energy
• Accelerating healing
• Reducing inflammation and pain
• Improving blood circulation
• Activating the body's own healing mechanisms

What can you use laser therapy for?

• Muscle pain and tension
• Joint problems and arthritis
• Sports injuries and strain
• Nerve irritation (e.g., carpal tunnel syndrome)
• Skin problems
• Wound healing and scars

How many laser treatments are needed?

It depends entirely on what needs to be treated. Many notice an improvement after just a few treatments. Sometimes, repeated sessions are necessary before the laser therapy helps.

How to use light therapy lamps

All of our light therapy lamps, including laser therapy and red light therapy pads and products, naturally come with a user manual so you know exactly how to use the products. Some of the products have a rechargeable built-in battery, while others (slightly larger units) must either be connected to a power outlet or a power bank can be used. If you are unsure about how to use Heat Sense products, you are always welcome to call or write to us - Contact us

What does infrared light do?

Infrared light is a type of light that is invisible to the naked eye but has a long wavelength, allowing it to penetrate deeply into muscles and joints, and offers a range of health benefits.

• Increases blood circulation
• Reduces inflammation
• Relieves pain
• Promotes muscle recovery and healing
• Improves skin health
• Enhances sleep quality
• Stimulates hair growth

What does infrared light help with?

Infrared light, which is in our red light therapy and laser therapy products, has a wide range of benefits – both for the body and the skin. It is a gentle and natural form of treatment that uses deep light energy to stimulate and help the body's own healing. Infrared light helps with:

1. Muscle and joint pain
   • Relieves chronic pain (e.g. back, neck, arthritis)
   • Increases blood flow → less stiffness and tension

2. Injuries and recovery
   • Helps with faster healing of:
     • Sprains
     • Muscle fiber tears
     • Overload
     • Sports injuries

3. Inflammation
   • Reduces swelling and inflammation in tissues and joints
   • Beneficial for arthritis, tenosynovitis, etc.

4. Nerve pain
   • Can relieve e.g. sciatica, carpal tunnel syndrome, neuropathy
   • Helps to calm irritated nerves

5. Skin and beauty
   • Increases collagen production → healthier and firmer skin
   • Reduces wrinkles, fine lines, scars and acne
   • Helps with rosacea and inflammation of the skin

6. Energy and well-being
   • Many experience better sleep, more energy and less fatigue
   • Stimulates cell metabolism and ATP production

What does laser therapy do for muscles?

When using our infrared lasers, which are LLLT (Low-Level Laser Therapy), the aim is to stimulate the body's own healing at the cellular level.

1. Increases cell energy (ATP production)
   • The laser light stimulates the mitochondria (the cell's “power plants”) to produce more ATP.
   • This gives the muscles more energy for repair and regeneration.

2. Increases blood circulation
   • Improved blood flow means more oxygen and nutrients to the muscles, and faster removal of waste products such as lactic acid.

3. Reduces inflammation
   • The laser light inhibits the release of inflammatory substances and helps to reduce swelling, heat, and pain.

4. Minimizes muscle tension
   • Especially for chronic tension in the neck, back, or shoulders – many experience muscular relief and relaxation after laser treatment.

5. Accelerates healing after injuries
   • For example, in the case of sprains, muscle fiber tears, muscle soreness, or strain.
   • Can significantly shorten recovery time.

Laser therapy helps muscles heal faster, reduces pain, and function better – all by stimulating the body's own mechanisms without causing harm.

What does laser therapy do?

Laser therapy is a form of therapy that uses low-intensity laser light to stimulate the body's cells, helping them to function better and heal faster. It helps with, among other things:

• Faster recovery
• Pain relief
• Faster healing after injuries, strain, wounds, etc.
• Reduced inflammation

What is laser therapy?

Laser therapy is a non-invasive treatment method that uses low-energy laser light to stimulate the body's cells, prompting them to heal faster, repair themselves, and relieve pain. The laser therapy light penetrates the skin and affects the cells' energy "factories," namely the mitochondria. This causes them to produce more ATP (the cell's energy), which initiates:

• Healing of tissue (muscles, tendons, nerves, skin)
• Reduced inflammation
• Reduced pain and stiffness
• Increased blood circulation and oxygen in the area

What is red light therapy?

Red Light Therapy (RLT) is a treatment method where red light combined with infrared light is used to stimulate the cells in the body. In Danish, it is called rød lys terapi. It is a non-invasive form of therapy that can help with:

• Relieve pain
• Minimized sore muscles
• Restore muscles after hard training/stress
• Faster healing after strain
• Minimize inflammation
• Heal wounds and scars
• Minimize hair loss (alopecia)
