How Lasers Work in Laser Hair Removal

Laser hair removal works by the process of selective targeting of a specific area of the body and using a specific wavelength to absorb light into that area. It does not work on a hair by hair basis, instead it focuses a wide beam of light that treats many hairs at one time. The wavelength of light absorbed has to be sufficient enough to damage the targeted tissue area while leaving the surrounding area basically untouched. The principle behind this process is called selective photothermolysis.

Lasers are intense beams of monochromatic and coherent light. These light beams are produced by laser devices that contain either minerals or gases. The four main types of lasers are solid state, semiconductor, gas and dye.

An electric current stimulates the gas or mineral properties which excites the atoms. The atoms then emit narrow, cohesive, parallel light beams which are all the same wavelength. The light beams are focused just for a fraction of a second on the dark hair pigment at the matrix of the dermal papilla, which is the small, cone shaped indentation at the base of the hair follicle that the hair bulb fits into. The light beam is absorbed and heats the pigment which vaporizes the dermal papilla. The more intense the light beam the hotter it makes the pigment. This results in the dermal papilla being severely damaged or destroyed.

Most people believe that laser hair removal works best on hair that is in its anagen phase. This means that the hair is actively growing and is attached to the dermal papilla. The theory behind this belief is that if the dark pigment in the hair shaft extends all the way down to the dermal papilla, it will be destroyed and vaporized by the coherent light beam that is focused upon the area. This happens because the light beam will follow the dark pigment all the way down to the derma papilla.

Visible light has wavelengths that range from 390 to 770 nm, or nanometers. Lasers operating in this range allows for successful laser hair removal without causing any damage to the dermal tissue. Lasers with a light source that operates between 700 to 1000 nm targets melanin in the hair shaft effectively. For example, the wavelength of an alexandrite laser is 755 nm, which is red in the visible range of the electromagnetic spectrum, making its target melanin. The stronger, or greater, the wavelength, the deeper it penetrates target selectively absorbing the wavelength.

Laser hair removal uses several varying wavelengths of laser energy. These wavelengths range from near infrared radiation to visible light. The three most commonly used lasers for hair removal are Alexandrite, Pulsed diode array, and NeoDymium Yttrium Aluminum Garnets, Also know as Nd:YAGs. The wavelengths of these lasers are 755nm, 810nm, and 1064nm respectively.

Laser hair removal utilizes a complex system of science and physics which are precisely balanced to work effectively and safely on the human body. As technology continues to advance in laser hair removal, this process continues to grow in popularity.

THE DEEP TISSUE MASSAGE

The deep tissue massage is a kind of massage therapy which centers its attention primarily on the ailing, the sore, the painful and the distressed deeper layers of muscles and connective tissues. Its therapeutic benefits are particularly beneficial for chronically tight and constricted areas such as in cases of stiff necks, tightness of lower backs and aching shoulders. The strokes of the Deep Tissue massage are not very different from those of any other types of massage therapies but they are slower and with more pressure applied to reach deeper while focusing on troubled areas.

The Deep Tissue massage is so important in certain painful contractions and spasms due to stress, strain or injury because that is the only way to get to the root of the problem as it is embedded deep under the surface where adhesions which are the causes of the pain and rigidity in muscles, tendons and ligaments are found. Left to their own wills, adhesions obstruct circulation in the affected areas to limit the blood flow which leads to the pain, the restricted movement and, ultimately, to the inflammation. By applying firm pressure and direct friction across the grain and fabric of the muscles, the Deep Tissue massage aims to break down those troublesome adhesions to restore proper blood circulation, reinstate full movement and heal the inflamed tissues. The therapists performing the Deep Tissue massage may use fingertips, knuckles, hands, elbows and forearms during the therapy session and alternate them during the various stages. Clients are frequently asked to take in deep breaths as the therapists dig deeply into a particularly tense area.

Because the Deep Tissue massage is somewhat intense, it should not be applied under the following conditions:

* Infectious skin disease, rashes, bruises, inflamed skin, tumors or open and unhealed wounds.
* Immediately or soon after surgery or recent fractures.
* Immediately or soon after chemotherapy or radiation treatments, unless approved by the clients physician.
* Osteoporosis patients, unless approved by the treating doctor.
* Clients who are prone to blood clots.
* Heart disease patients, unless recommended by their cardiologists.
* Pregnant women should get their massage treatments from professionals who are certified in pregnancy massage.
* Abdominal hernia.

The good news is that Deep Tissue massage really works and it usually works very fast. Often, clients will walk into a session with excruciating pain and walk out a couple of hours later with smiles of relief on their faces. The bad news is that, depending on their tolerance level to pain, most clients experience it to one degree or another at certain point during the session. In addition, there is usually some measure of soreness immediately after the treatment which can last up to an entire day. However, the pain of the Deep Tissue massage therapy and the lingering soreness afterwards is nothing compared to the pain before the treatment and it comes with the knowledge that it will all be over very shortly. The massage therapist may suggest applying an icepack to the sore area but it is rarely severe enough to warrant it.

When most massage therapies are aimed at relaxation of the body and mind and the massage is generally applied to the entire body, the Deep Tissue massage sets its sights on precise problematic areas such as those afflicted with:

* Chronic or acute pains
* Diminished mobility or limited range of motion.
* Healing areas after traumas or injuries caused by falls, sports injuries, whiplashes from car accidents and so on.
* Strains from repetitive motion such as the carpal tunnel syndrome.
* Pains due to incorrect posturing of the body.
* Pains from osteoarthritis. According to a study conducted and reported by the Consumer Reports magazine, over 34,000 people classified Deep Tissue massage therapy as being more effective in alleviating osteoarthritis pain than physical therapy, exercise, prescribed or over-the-counter drugs, glucosamine, diets, acupuncture or chiropractic treatments.
* Fibromyalgia. Statistics have shown that Deep Tissue massage is more successful in easing symptoms of Fibromyalgia than any other available curative remedy.
* Muscle tension, contractions or spasms.

To flush out metabolic waste from the massaged tissues, clients should drink plenty of water after the Deep Tissue massage therapy and enjoy the fact that they are as good as new again.

Body Detox Naturally Remove Unwanted Toxins

Toxicity is one of the greatest concerns in the 20th century. This is because there are several factors contributing in the development of toxins in the human body such as stronger chemicals, water and air pollution, nuclear power, and radiation. Many people are ingesting new chemicals, using all kinds of drugs, eating more sugar as well as refined foods, and abusing themselves with various sedatives and stimulants.

These toxins lead to an increased incidence of acquiring diseases as well. Some of the most dangerous are cardiovascular illnesses and cancer. Others include obesity, allergies, arthritis, and other skin problems. Moreover, it also displays symptoms including fatigue, headaches, pains, gastrointestinal problems, coughs, and other problems associated with weak immune system.

These chronic and acute illnesses can be alleviated through cleansing or detoxification program. This process naturally eliminates the harmful toxins from the body. It can either be a short-term or a long-term procedure. Those people who are addicted to some substances are well benefited by this program. They can temporarily avoid addictive agents and later on withdraw from their abusive habits.

Take note that toxicity can occur on two major levels. It can either be internal or external. External toxicity is acquired from the environment through breathing, ingesting or physical contacts. It also includes the chemical characteristics of foods which affects the health. Most food additives, drugs, and allergens create the bodys toxic elements. In fact, substances such as sodium, many nutrients, and even water have toxicity in particular circumstances.

On the other hand, internal toxins are internally produced by the body from its daily normal functions. Cellular, bodily, and biochemical activities are producing substances that should be eliminated. These free radicals known as biochemical toxins can cause inflammation or irritation of the tissues and cells which blocks the normal functioning of an organ, cells, or entire body level. All kinds of microbes, foreign bacteria, intestinal bacteria, parasites, and yeasts produce waste products that are metabolic. Emotions, thoughts, and stress also increase biochemical toxins.

Almost everybody needs to detoxify their bodies so that it can function well. Detox or cleansing is a trilogy portion of the nutritional action. Eating balance diets and avoiding excesses will need lesser intensive detoxification. Although the body has its elimination cycle carried out mostly at night and early morning, eating a congested diet with higher fats, refined foods, dairy products, and even intake of drugs can procure lots of body toxins. That is why body detox is needed because some individuals are having this kind of lifestyle.

Fasting is a detox therapy that is sometimes incorporated. It is considered as the oldest and complete natural treatment for humans. Detox processes can help clear dead cells, wastes, and revitalize the natural functions as well as the healing capacities of the body. Well, many people are claiming that cleansing programs have incredible and positive results on their body.

The proper way of eliminating these toxins is very important to the health of a person. Although the body can handle certain amount of toxins, it is always necessary to think of reduction or elimination in case of excess toxin production and food intake occurs. Of course, in the end you will be benefited with a well-working and stronger immune system to prevent diseases from attacking you. In this way, you will live a much better life.
