Light Therapy for the winter season
When the sky is gray and the days grow short our morale is unharmed. Everyone can be affected by the loss of light in the dead season. It's now or never to chase away the sadness of crossing or seasonal depression with the help of href = "http://solvital-lighttherapy.co.uk/index.asp?ID=881"> light therapy.
A quarter of people see their lives turned upside down by rhythm of the season, where as 2 or 3% of people suffer serious depression due to this time of year. It is only since the mid-80s that researchers began to seek the reasons for this state of depression. A person suffering from seasonal depression tend to see increased appetite, have a taste for sugar and have a need excessive sleep. Because the symptoms are different from regular depression, Dr. Marc Hébert researcher and professor at the University Laval Robert Giffard, thinks it is necessary treat patients differently. Instead of giving a Percription of antidepressants praises a healthy solution: Exposure to light.
The eye: window to the brain
"Contrary to what many think the eye is not an external body, but an extension of the brain" says Dr. Hebert. All games between the two ears, but because it is extremely difficult to study the organ in vivo, the study of the eye is composed of an interesting window.
If the brain seems to be affected by the lack of light, we do not know what makes certain people more vulnerable than others. It is through the analysis of the retina that multidisciplinary directed by Dr. Hébert, composed of researchers from neuroscience in psychologists and psychiatrists opthalmologyof resulting in learning more about the role of light in brain. "Many neuro sick thinking that the eye is the vision of the person is not affected, said (...) that we are capable of neurotransmitters appears to the eyes studyin and we can see the effects after four weeks of light therapy sessions. "
Serotonin and dopamine are the two most common neurotransmitters are directly related to humor. If there is a chemical imbalance of neurotransmitters can initiate a depression.
Light therapy
Light therapy treatment, the therapy consists in lux or photo of exposure to bright light at the same level of 5000-10 000 lux (units light), under controlled conditions. The comparison of holders of regular lighting that we have in the house or office of only 100 to 150 lux.
The advantage of this treatment is that you can do at home. The price of treatment with light of a lamp near $ 250. Some pharmacies also offer trial months. The cost deduct rental if you decide to buy the lamp. It is better to buy a lamp made especially for this purpose instead of making their own, says the specialist (s a danger to eyes and skin).
The use of a phototherapy lamp can be varied, since the user can remain active during the sessions. Dr. Hébert PERSONNALY use all the time at work lamp on your desktop. It also suggests that people put on the table while eating breakfast or are reading a newspaper. The person must keep his eyes open, but not to keep looking at the light. The person may have on your business, while exposure to light. You can match Exposure sessions and the intensity of light by its own power and needs, which may change each month of each year. After an hour a day, the benefits, show a week later. Sure it is first and foremost, consult a physician to decide whether the problem is affect the person is actually seasonal depression.
Skeptics
Despite its benefits, the light The therapy has yet scepitcs in the medical community. "There are psychologists and psychiatrists who do not believe in it, stresses Dr. Marc Hébert. They were surprised to discover that a number of patients who responded in the same manner the light therapy sessions. "Indeed, it seems that the treatment works for 70% of people who suffer of seasonal depression. One advantage of this treatment is the possibility offered to everyone, able to anticipate the blue before the arrival of autumn.
"We know that the treatment of light therapy works for people affected by winter depression, but do not know yet theraputic action mechanical says Dr. Marc Hébert, who specializes in the field since 1992. We note that the biological response to light therapy, which allows us to conclude that it is not a placebo effect, but a real effect. "
According to Kino Québec, a person is "more likely to be in a good mood and have the spirit, if your level of melotonin (sleep hormone) is not too high during the day "exposure to light helps increase the level of mealtonin. NGOs suggest that the practice of outdoor sports, even when off, and in the light of day will always be superior light found in the doors. While the Russian Academy of Medical Sciences showed that physical exercise also had positive results, such as light therapy for people suffering from affective disorder "target = "_self" Href = "http://solvital-lighttherapy.co.uk/index.asp?ID=916"> seasonal affective disorder.
If the idea of exposure to artificial light puts out, nothing prevents you from changing your habits and go enjoy the summer sun or winter. You should know that the sun produces 100 000 lux during the summer, but the light intensity is lower in winter, so that only 20 000 lux on average. The statistiques show that during the summer daily exposure during the day is 2 hours so during the winter which is just 30 minutes. Never forget that the sun's intensity is approximately 25 times more powerful than a phototherapy lamp.
