Experiments indicate that individuals who suffer from Seasonal Affective Disorder (S.A.D.) are affected by light, which plays a major role in the secretion of melatonin. Melatonin is a natural hormone made by your body's pineal gland. This is a pea-sized gland located just above the middle of the brain. During the day, melatonin levels are barely detectable in individuals who don't suffer from S.A.D.

Bright light therapy involves the regular (usually daily) exposure to a bright light source. Treatments typically involve an artificial light source of accepted therapeutic intensity and having peaks in specific wavelengths, with exposure duration of a set period and distance from the light source.

Intense Pulsed Light (IPL) therapy is an effective way to rejuvenate the skin, giving it a more youthful appearance. Light-based treatments use a less-intense, broader spectrum of light than lasers, but are effective in treating rejuvenation of the skin. Candela's Ellipse I2PL is the only light-based product that is built specifically to dual-filter light as it is absorbed, thereby generating more consistent results.

Bright light therapy has been extensively researched at leading institutions worldwide for over 25 years. Most people experience no side effects; however, some individuals may experience minor side effects (headaches, eye strain, and occasional nausea) that tend to disappear after the first few days of exposure. Bright light therapy has proven safe and highly effective when used under the supervision of a trained clinician or physician.

Exposure to bright light effects changes in a person's circadian rhythms. Thousands of people find relief through bright light therapy, though the physiological mechanism is still uncertain. Such exposures suppress the secretion of melatonin (which makes us sleepy), and increase the secretion of serotonin (which keeps us alert and full of energy), but which of these influences are the primary mechanism is not yet known.

No. Thousands worldwide avail of light therapy every year without any negative effect. There is no evidence that standard light therapy (properly administered to people with normal visual function) is harmful to the eyes. However if you have a history of visual difficulties apart from wearing glasses (e.g. cataracts, ulcerated cornea etc) then be sure to consult with a doctor before undertaking light therapy.

Very few people report side effects from receiving bright light administration. Some people may initially experience slight eye stress or a headache, which tends to dissipate the longer the exposure to the light. Re-Time® Jetlag Glasses™ emit light of about 1200 lux intensity into the eyes of the wearer. As a comparison, on a bright sunny day the brightness looking toward the horizon is about 100,000 lux.

Response to light therapy is usually very quick, and most people will notice a marked improvement within one week. Most people similarly experience a rapid recurrence of symptoms if they stop using their bright light system. Longer trials have also shown increasing response to light therapy after two weeks, with still more incremental improvements after three or four weeks.

This one has been beaten around a little. Some people claim looking at the Sun induces sneezing, others say it impedes a sneeze: Sneezing, Sun Sneezes, sneezing, and Sneezing and bright light

Bright light is the most effective way of re-timing our body clock to an earlier or later time. This is because our actual body clock (consisting of a cluster of cells that lie deep within the brain) receives information from the eyes about light (daytime) and dark (night). However, the timing and length of exposure to bright light is critical as to whether your body clock will be delayed (to a later time) or advanced (to an earlier time).

Light helps control your body clock (or circadian rhythm). There are 2 hormones that greatly affect your body clock: Serotonin and Melatonin. Serotonin tells your body that it is time for you to be awake, and Melatonin tells your body when to sleep. When your body clock gets off track, your body is releasing these hormones at the wrong times. This causes you to have abnormal sleep cycles, as well as mood and energy problems. Light is used to control when your body produces these two hormones.

The tissues in which interference fields are found can be shown to have abnormal cell membrane resting potential (abnormal electrical charges on the cell surfaces). This creates electrophysiological instability and abnormal afferent signals (nerve signals to the spinal cord and brain) which, in turn, trigger abnormal autonomic nervous system responses. Procaine has a membrane-stabilizing effect (much like lidocaine in treating cases of irregular heartbeat or cardiac arrhythmia).

Laser therapy is a safe, effective, and commonly used treatment, providing optimal results in areas such as the removal of unwanted hair skin rejuvenation, wrinkle reduction, leg veins, or tattoos; and the treatment of acne. Lasers work by delivering an intense beam of light that is absorbed by the skin. This light is converted to heat and is absorbed by the cells being targeted, while leaving the surrounding tissue unaffected.

The ChildTrauma Academy, a not-for-profit organization based in Houston, Texas is a unique collaborative of individuals and organizations working to improve the lives of high-risk children through direct service, research and education. Dedicated to clinical, research and legal approaches to solving problems of childhood trauma.

The optimum time for taking light therapy in the morning is best gauged by determining the onset of melatonin in the evening. In external clock time, this can differ by several hours between individuals, and using the light too early or too late will greatly reduce its benefit. Melatonin is a nighttime hormone. At a certain point in the evening, levels of melatonin begin to rise because the biological clock has told the pineal gland in the brain that produces melatonin, 'Now it's night.

Low level laser photons irradiate the entire scalp increasing micro-circulation of blood supplies to the hair follicles. Pure red, "soft" laser light stimulates the scalp, significantly increasing the number of red corpuscles that deliver life giving oxygen and nutrients to the hair bulb. Hair follicles, which are "dormant" but not dead, can often be rehabilitated as debris is flushed from the hair shaft, swelling the cortex and closing the cuticle.

LPL uses pulses of visible therapeutic light over many wavelengths that deliver energy to all layers of the skin. LPL treatments, which last about 20 minutes, work on the principal that light is absorbed by color and that light generates heat.

Omarian: Acu Light Color Therapy uses the eyes and large areas of the skin as entry for frequency, as well as focused points, on the skin's surface to transmit biophotons (particles of light) through the body's own photon grid system. Using gentle light impulses, it imparts healing information within the body, mind, psyche and emotions. Acu Light recognizes that a harmonious flow of energy through the body will support good health and optimum well-being.

The innovative Pulsed Light technology uses a specially filtered spectrum of intense light with wavelengths designed to kill the bacteria that causes acne. Other light energy is generated to reduce the inflammation associated with active acne in the treatment area.

Laser/light selectively targets the melanin in the hair so it is most effective on light, clean skin with dark follicles. After your initial preparation, your treatment provider will move a wand-like hand piece over your skin. The hand piece emits the light that disables the hair follicles. Most people perceive the light as a gentle "snapping" sensation. Once this is completed, the treatment provider will wipe away any loose hair from your skin, and you're ready to go.

Unlike most existing light therapy devices, which are large and clunky in design, The Litebook® is extremely compact, lightweight yet durable, portable, and aesthetically pleasing. The Litebook® also features several innovative elements: bright-white light-emitting diodes (LEDs), and optional DC power supply for use on airliners and motor vehicles.

Light therapy is the shining of bright light into your eyes, typically for a half hour each session. Mood & Sleep Disorder clinics recommend 10,000 lux light levels Since the 1980's, light therapy has become the first line treatment for Winter Blues and SAD. Bright light can also be used to shift your circadian (wake/sleep) cycle, so it is used to prevent jet lag, minimize work shift change fatigue, and help abnormal sleep phase insomnias.

Light Force Therapy uses light emitting diodes or LEDs to produce a unique combination of frequency and wavelength of safe low-level infrared light, which helps to elevate muscle tissue temperature and increase circulation. All of these factors are essential in relieving discomfort and relaxing muscles, making Light Force Therapy extraordinarily effective. Light Force Therapy is free from dangerous UV and laser rays.

Laser Therapy or "photobiomodulation", is the use of specific wavelengths of light (red and near infrared) to create therapeutic effects. These effects include improved healing time, pain reduction, increased circulation and decreased swelling. Laser therapy adds energy to living systems. While we are able to explain many of its molecular and biochemical effects, it also adds energy at atomic and subatomic levels.
