Hi guys,
I will like to talk about something that is so important to everyone however not readily available to many.
Let's talk about the importance of Light and light therapy?
Yes, you heard me right!
Light and Light therapy.
The truth is that living in a third world country like Nigeria, light, also known as electricity, is a luxury that many don't have. Mind you not that they can't afford it but the government refuse to supply enough to go around and most importantly, constant.
So haven't said this, I would like to talk about the importance of Light and why light therapy is needed in a country like mine.
Even the world was created to have both light and darkness. Light is energy and it is used for everything under the sun. For food processing, for chemical reactions both in plants and animals etc. If you ask how, then this blog isn't for you.
Anyway, light from the sun was the first light, then man discovered fire, and yet again discovered electricity.
If light was important to the existence of human, many years of innovation will not be needed.
What is light therapy?
Light therapy, also known as phototherapy, is a treatment in which you’re exposed to an artificial light source. The therapy primarily treats major depressive disorder with seasonal patterns (formerly known as seasonal affective disorder, or SAD). This is a type of depression that occurs during a certain time of year, usually winter. Light is also used to treat other conditions, including sleep disorders and other types of depression.
How it works
Typically, light therapy is meant to compensate for the lack of exposure to sunlight that is thought to be linked to major depressive disorder with seasonal patterns. You’ll sit near a light box, which emits strong light. The light usually mimics natural sunlight, but there can be variations. A unit of measure called a lux gauges the amount of light used in a treatment. The standard output of a light box is between 2,500 and 10,000 lux.
Treatments usually begin in the fall and continue until early spring. Sessions commonly last from 10 to 15 minutes. The length of the session depends on how well you handle the treatment and the strength of the light box. Someone new to the method may be given shorter initial treatments. The more powerful the light box, the shorter the treatment session can be.
Why light therapy is effective is still being studied. One theory is that light naturally triggers the production of serotonin in the brain. Serotonin is the “feel-good” brain chemical. Some experts believe that success with light therapy is due to a placebo effect.
Side effects
There are side effects to light therapy, including headache and sunburn. Usually, these are not serious. Most side effects can be dealt with by adjusting the duration and intensity of the sessions. Other treatments that can alleviate side effects include:
eye drops
nasal drops
sunscreen
If you’re considering this therapy, you should consult a physician if you have any of the following conditions:
sensitive skin
eye conditions
a history of skin cancer
Pros of light therapy
Light therapy has many positive aspects. The treatment can also be done at home using rented or purchased light boxes.
Light therapy is
noninvasive
safe
convenient
associated with few or mild side effects
The negative aspects of light therapy are the side effects and complications that can occur. These include:
headache
insomnia
sunburn
fatigue
dry eyes and nose
hypomania, an extended period of heightened mood
What the expert says
Dr. Carl Vincent, a psychologist in Moline, Illinois, suggests that light therapy be used with other treatments, such as psychotherapy or a drug regimen. “The idea is that it could be used as a supplemental therapy,” Vincent says. “In addition to treatment, people suffering from depression in the winter months should try to be more active. Winter is a time when people tend to be more sedentary, and getting more exercise can help improve mood.”
The takeaway
Light therapy is used to treat major depressive disorder with seasonal patterns, sleep disorders, and other types of depression. It is often effective, though doctors do not know exactly why. It can have a number of side effects, most of which can be effectively alleviated. Talk to your doctor if you feel light therapy might be useful for you.
