In comes the sunshine. That's how some people describe the benefits of therapy lights. Scientists think that simulated intense light has an effect on chemicals in your brain and your skin and that they can be used to help some conditions. There are lots of different types of therapy lights so I'm going to described just a few of them and the conditions that they can be used with: Light boxes (Phototherapy or bright light therapy) Many therapists have noticed that sitting near a simulated sunlight box can alleviate symptoms for some complaints. The strength of the light should be at least 2,500lux and daily exposure is required. Remember that a medical practitioner must prescribe the strength and type of light used as well as the duration of exposure. SAD Light Boxes Otherwise known as Seasonal Affective Disorder or its mildest form 'Winter Blues'. You don't have to be a genius to know that we all feel better during the long sunny days of summer. We seem to have more energy too. You lose some of that enthusiasm in the winter when there are not so many daylight hours. Some people get 'winter blues' which makes them feel lethargic and 'under the weather', with a tendency to overeat. For others this becomes severe enough it to disrupt their lives and cause a lot of upset. It can also affect the way we behave. The symptoms usually start at the beginning of the winter season and begin to get better when spring arrives in March and April. It may not be necessary to use light SAD therapy daily during the winter months and advice from a trained professional is advised. Jetlag and Sleeping Disorders Where the circadian rhythms or the brain's body clock has been affected by periods of sleep deprivation or extended night or day. If you fly over time zones it can have this effect. The light box can emulate the difference between waking hours and sleep or nighttime and can help you to re-adjust your body and brain into rhythm quickly. Alzheimer's and Dementia Sufferers There are lots of research papers written on Alzheimer's Disease and many of them deal with the damage that happens to the part of the brain that controls the circadian rhythms. Damaged nerve pathways together with poor eyesight as you get older can lead to indoor levels of light being insufficient to tell the difference between day and night. There have been experiments to find out how therapy lights and light boxes can be used and they have determined that they can help to maintain the rest and activity cycles of Alzheimer sufferers' for longer. UVB/UVA1 Light Box Therapy The same technology that is used for sunbeds in tanning shops can also help to ease stubborn patches of psoriasis, vitiligo, stretch marks and pale scars. The light must be focussed on the affected patch without unwanted exposure to normal skin. Coloured-light or Intense Pulsed Light Therapy With these types of therapy lights, floodlights have colored filters in order to bathe the skin in light of different wavelengths or colors. It has been shown that certain colored filters are better for different conditions: Blue: is used to destroy the bacteria that cause acne. Green: is used to treat pigment irregularities e.g. liver spots, age spots, Yellow: for vascular conditions such as thread veins and rosacea. Combination green and yellow: smoothes away fine lines and wrinkles. Red: has been found to be effective in the relief of headaches and, when concentrated in one area, for the relief of arthritic pain. Low-Level Laser (Ruby and KTP) Therapy Laser treatment has been developed to help shrink patches of discoloured skin like moles or birthmarks. The pigment (melanin) in the skin absorbs the laser light, which causes darker areas to break up and help it to look more normal. The two therapy light systems above can be combined and used to remove areas where there is too much hair. The information in this article is not advice. If you wish to try any of these treatments or equipments you should always first contact your medical practitioner.
