Bipolar light therapy can improve mood and daytime alertness. Light therapy is often used as an adjunctive treatment for patients who experience residual depressive effects while taking lithium or valproate as mood stabilizers. Light therapy can also be useful for those who need to minimize medications, such as pregnant women or the elderly. A study conducted at the at Northwestern …
How can something as simple as manipulating the time you sleep – chronotherapy – work so well to improve the quality of your sleep, your energy during the day and your mood? A young mother who has often complained of feeling tired with many problems with aches and pains came in with a big smile today… “I am feeling so …
Weak circadian rhythms, seasonal mood symptoms, and disrupted sleep and daytime fatigue are common problems for people with depression and bipolar, the Luminette light therapy glasses may be a key part of a practical strategy to counteract these problems. Light therapy (very bright light, usually in the morning) has been shown to improve seasonal and non-seasonal depression in people with …
The news that bipolar depression light therapy may be effective is good news and follows a series of studies this past year highlighting the importance of treatments that affect circadian rhythms by manipulating light and dark in treating mood disorders. Bipolar depression is one of the hardest conditions to treat effectively. Antidepressant medications may have significant side effects, including inducing …
Several of my patients reported odd changes in their sleep and their energy level this past week, as though there was an epidemic of fatigue going around. They noted that their sleep was a bit more disrupted and that they didn’t feel as rested in the morning and, for the first time in months, they began taking afternoon naps. Going …
Bright light is one of the most rapidly effective treatments for depression and may be helpful for depression even in people without a clear seasonal pattern (winter depression). A recent study suggests that it may also be true that darkness treats mania. The portion of the light spectrum that affects circadian rhythms the most strongly is blue light, which is …
Bright light may work for non-seasonal depression. This is the conclusion of a study published in the prestigious psychiatric journal JAMA Psychiatry. Researchers at the University of Toronto and the University of British Columbia in Canada conducted a randomized, double-blind, placebo- and sham-controlled, 8-week trial in adults (aged 19-60 years) with major depression of at least moderate severity. 122 patients were …
In February the National Sleep Foundation announced the publication of new guidelines for the amount of sleep that we should be getting based on a rigorous review of the literature. The guidelines suggested that adults should be getting between seven and nine hours of sleep. The results were widely distributed and commented on. It was noted that many people in our …
Chronotherapy for depression was recently shown to be effective in a fairly large and well designed study from New Zealand. What is chronotherapy? As discussed in the article, which appeared in Acta Scandanavica Psychiatrica, chronotherapy involves some combination of three separate sleep and wakefulness related interventions: Wake therapy. Wake therapy (previously known as “sleep deprivation” therapy, a harder sell to patients) …
I ran across a wonderful tool for circadian rhythm self assessment on the website of the Center for Environmental Therapeutics. The Center is devoted to providing the public and clinicians with high-quality information about natural interventions for people with stress, anxiety, and depression. I took the online test and it said I was definitely a morning person. Which is true now, …
Seasonal affective disorder affects many of us to some degree. Once again, it is nearing the Autumnal Equinox. This is the so-called “beginning of fall.” And for many people, it is around this time that they notice the shift from summer towards fall and winter and begin to experience a sense of fatigue or lethargy that can be the precursor …
What is the power of a morning walk? Even such a simple daily ritual can have profound effects on mood. After two years working with a young woman who is now heading off to graduate school and bright future, we were reflecting on lessons learned. “I can be a bit dense about cause and effect. I am surprised when something …
Those who experience depression regularly at certain times of the year (in San Francisco, a winter depression usually begins in late October or early November and, depending on where you live, there may be a summer depression linked to heavy fog in July and August) should definitely know about the importance of light exposure in treating depression. In fact, regular exposure …
Two recent articles that I reviewed highlight the accumulating evidence that something as simple as sunlight has profound impacts on brain biology. When I suggest to people that they pay attention to daily light exposure and, particularly, to getting bright light for 45 minutes every morning, I am often looked at with skepticism. “Sure doc,” I hear the other person …
Christmas vacation is ending, It has been wonderful to spend some relaxing time with family, getting up later in the day, lounging around and playing games, reading, or watching TV… and eating too much good food. Now the challenge is getting back to a more productive schedule. For many of us, our bodies are in a “hibernating” mode that makes …
As August winds itself up, it is time to start thinking about the fall and then winter coming up. A little bit like the squirrels, who are already putting away food for the winter, it may make sense to make sure that you have what you need to have a happy and energetic fall and winter. The first thing is …
As we slowly move from summer to fall, it may be timely that the issue of Biological Psychiatry that arrived in the mail today is devoted to how the brain’s clock affects mood. It points to growing evidence that part of what drives mood cycles are disruptions in the brain’s daily (circadian) rhythms. It appears that people who are vulnerable …
For those of us in the northern hemisphere this is a day well worth celebrating. Today marks the shortest day of the year. Or, to put it another way, from here until summer every day will be a little bit longer, there will be a little bit more light, and eventually the days will get warmer and we will have …
There has been considerable skepticism about the value of light therapy for people with seasonal depression, despite a very compelling research literature. Perhaps this might, in part, be because the way that light might affect mood has not been clear. In a recently published animal study, change in light exposure increases stress hormones, depresses mood, and impairs learning through changes light …
Traveling can be exciting, but it can also be very stressful. It is particularly important for people living with moods to do prepare for travel before they leave. A surprisingly high percentage of serious mood catastrophes, in our experience, happen during trips. And they are almost always preventable. First, if your traveling to some place without good medical care, it’s a …
