Light therapy is used to treat a variety of mood disorders and depression symptoms. It is believed that light affects the circadian rhythm of the body and reduces the levels of melatonin produced by the brain. This in turn reduces feelings of mental fatigue, sadness, melancholy, and postpartum depression.

The form of light used in light therapy mimics the spectrum of natural outdoor light. Essentially, it places the user in a simulated sunlight for a prescribed period of time each day, usually thirty to ninety minutes in the morning hours. Participants treated with light therapy usually report improvement in symptoms within a week of beginning treatment, and use of antidepressant medications is reduced in those patients.

Patients also generally report improvement in sleep patterns and less disruption in sleep schedules. This is likely due to the stabilization of melatonin production, allowing normal patterns to emerge wherein drowsiness occurs at night and not during daylight hours. Obviously, simply experiencing adequate sleep will in itself bring about improvement in symptoms of depression, as chronic fatigue usually adds to depression-inducing stress.

Light therapy is particularly helpful for those individuals who either cannot use chemical antidepressants, or those who simply choose not to. Patents residing in areas of the world where light is limited specifically benefit from the use of light therapy, as it simulates the natural pattern of light and darkness with which the human body most easily tunes itself. This simple and inexpensive therapy is an immensely helpful tool for depression sufferers.

Postpartum depression affects between 6% and 12% of new mothers in the United States, and is one of the leading depression diagnoses among adult women. Because definitive causes for PPD are still being researched and therapies sought that are safe for nursing mothers, alternative methods for dealing with depression following childbirth have emerged.

Light therapy has been used extensively for sufferers of seasonal affective disorder (SAD) with some success, and is now being recommended for mothers with mild to moderate postpartum depression as well. Clinicians recommend exposure to light in a light box for a duration of thirty to ninety minutes daily during the morning hours of the day. Eye protection is worn and the patient is instructed not to focus the eyes directly on the light but to keep the eyes open. Not only does the light therapy seem to have a positive effect on alleviating depression symptoms, but unlike some of the medications on the market for treating depression, it is safe for mothers who are breastfeeding their babies.

Mothers who reside in climates prone to extended periods of darkness, such as Alaska, experience higher rates of postpartum depression, leading researchers to believe in a link between reduced light and PPD specifically. Employing light therapy in such situations has proven highly effective in bringing relief to depression sufferers. Ongoing studies and practical application should fine tune this remedy for depression, widening the options for sufferers who cannot or who choose not to use chemical pharmaceutical treatments.

My first semester at college, I lived through my first real winter.  Growing up in southern California, I had grown accustomed to sunny, warm winters that allowed all sorts of outdoor activities.  My first real winter, with real snow and cold temperatures was nothing short of shocking.  I found myself feeling as gloomy as the weather and not wanting to be social.  I was not depressed and made it through without any serious winter wounds, but many suffer from even more serious symptoms.  Many, like me, find their moods going as low as the weather.  Unlike me, however, these people continue to spiral downward and feel additional symptoms of depression and lack of energy.  This is more than just the winter blues.  This is a medical condition known as Seasonal Affective Disorder, or SAD. 

SAD is very real and its symptoms are very real to those who suffer from it.  People suffering from Seasonal Affective Disorder feel depressed and feel the need to sleep often.  They lack energy and feel lethargic throughout the day, even the entire winter.  They have increased appetites and cravings for carbohydrates.  Their increased appetites lead to weight gain.  They also feel social withdrawals, and become increasingly anti-social and irritable. 

SAD is a serious condition that requires medical help.  Treatment can be found in the form of light therapy.  Lack of light causes SAD and light therapy can reverse its effects and have patients feeling sunny and happy. 

We’ve all been sad.  We are sad in a whole number of situations.  The store is out of our favorite candy, the movie is all sold out, our favorite team lost the big game, we failed a test, lost a promotion, broke up with a partner, hacked around on the golf course etc, etc.  Sadness can come at any time anywhere. There is another kind of sadness.  This sadness is depressive and occurs in the winter months and it comes with a lot of symptoms.  This sadness is simply not surprisingly, called ‘SAD.’ 

Seasonal Affective Disorder, or SAD for short, affects those who live in harsh winter climates that deal with long winter days, with little or no sunlight.  Lack of sunlight affects the body’s natural function, its internal clock.  When the clock is adjusted, a number of things can go wrong.  Symptoms for SAD often last throughout the winter, only going away when the sun finally comes back in the spring time.  If you have ever wondered if you are a victim of SADness, here are 3 main signs to determine if you have Seasonal Affective Disorder. 

First, Seasonal Affective Disorder is characterized by depression.  SAD patients feel down, depressed and anxious.  They often avoid others, even family and friends.  Second, SAD patients feel tired and lack energy often.  They sleep much more than normal.  Third, SAD affects patients’ appetites, especially increasing cravings for carbohydrates.  There’s the 3 main ways to determine if you are SAD.
