Light Therapy FAQ |
|
Light therapy has been used to treat certain conditions since 1984, when Dr. Norman Rosenthal of the National Institute of Health published a groundbreaking report into the positive effects of light therapy on seasonal affective disorder (SAD). Since then hundreds more research studies have been undertaken and many technological advancements have been made, meaning that light therapy is now an affordable and effective treatment for many different medical and sleep/energy-based conditions. Light therapy involves an individual sitting at a recommended distance from a fluorescent light box which produces a light intensity of between 2500 and 10000 lux (the Metric measurement of light quantity). Light therapy works by exposing the eyes to intense light. When the light hits the retina the light is transmitted by nerve impulses to the pineal gland which is responsible for melatonin secretion. This function can help moderate the body's internal clock, also known as the circadian rhythm. Light therapy is also able to reduce the daytime melatonin levels, while also enhancing the effectiveness of serotonin and other neuro-transmitters - which explains its ability to be able to effectively treat seasonal affective disorder, Alzheimer's and other mental disorders. Is Light Therapy Just For Those With Seasonal Affective Disorder (SAD)? While light therapy
is incredibly effective at relieving the symptoms of SAD,
it can be used for many more conditions and everyday situations. Light
therapy is now used to relieve the symptoms of jet lag, for
shift workers who need to alter their body clock, for those
who
have difficulty getting to sleep (or waking up!) and for
those who simply want more energy or a better night's sleep. For
more information on the uses of light therapy follow the
links below: Although light therapy is extremely effective to treat problems and disorders such as SAD, it is possible that there may be other influences that are causing the symptoms you may be experiencing. Seeking the guidance and support from a qualified medical practitioner is thoroughly recommended for both diagnosis and treatment. Do I Have to See a Specialist for Light Therapy? Thanks to the increase in technology and the advancements in our understanding from research, light therapy is now convenient and affordable for you to use at home, at work and on the go! Although it is always recommended to seek medical advice for any ongoing treatments, light therapy is one of the most effective and versatile treatments you can undertake in the comfort of your own home. How Long Does It Take Per Day? Intensity levels can be altered by moving closer or further away from the light box and each treatment session can range from between 15 minutes to three hours. A half an hour session at 10,000 lux or an hour session at 5,000 lux, once per day is about the average daily use. Can I Overdo Light Therapy? Yes, it is possible to over use light therapy and this may result in fatigue and irritability. Over use for a prolonged period of 28+ days can lead to these symptoms. Over use can also cause eye strain, however, when used correctly light therapy is an effective and natural treatment. How Often Do Lamps Need to Be Replaced? After approximately two to three years, the lamps in light therapy products can lose their intensity and may need replacing. |
