Using Light Therapy to Treat PTSD Sleep Disturbances

Friday, May 28th, 2010

There have been studies on the use of bright light therapy to improve sleep disturbances linked by combat-related post-traumatic stress disorder (PTSD).  Results are pointing to light therapy significantly improving sleep disturbances related to PTSD as well as moderate improvement in symptoms and depression associated with PTSD.

A lot of people who suffer from depression have problems with keeping a regular sleep cycle.  Those that use a light therapy box to regulate their sleep patterns, usually notice their symptoms for depression decrease.  Light therapy is an easy treatment that can be self-administered, and has few side effects.

There has been an ongoing study at the University of South Carolina that involves 16 soldiers who had been serving over seas.  The full article can be read from the following link:

The Circadian Rhythm and SAD

Thursday, May 27th, 2010

Circadian rhythm disorders are disruptions in a person’s circadian rhythm – a name given to the “internal body clock” that regulates the 24-hour cycle of biological processes in animals and plants.

The circadian rhythm is usually disturbed by pregnancy, time zone changes, medications, shift work, depression, or changes in your routine.

Depressives are notorious for being circadian out of sync – feeling sleepy or alert, warm or cold, hungry or without appetite, at the wrong times of day or night – as if they were jet lagged several hours.

Research suggests that for many depressives, the timing of bright light therapy is key, as if it were pushing or pulling their circadian clocks into sync. Indeed, for other conditions, tweaking the circadian clock is the express purpose of light therapy.

Seasonal Affective Disorder is also a symptom of a disrupted circadian rhythm.  Doctors fear that if a person’s biological clock is disrupted for too long, it could lead to cardiovascular disease, and a depreciation of melatonin could increase a patient’s risk of cancer.

Activities To Do While Using Your Light Box

Wednesday, May 26th, 2010

Many people that suffer from Seasonal Affective Disorder have been told to begin using a light box to help them recover from their winter depression.  Although many have problems with just sitting in front of their light box, that some shy away from treatment.

You can turn your light box on and sit in front of it everyday from 30 minutes to 2 hours.  You do not have to stare directly at the light box while you are sitting in front of it.  Actually, you shouldn’t, it can be harmful if you have macular degeneration. However, you should still sit directly in front of it.  Most doctors recommend using a light therapy box in the morning because that is when it is the most effective.  Therefore, it will be helpful if you use it while you are completely morning tasks.  Use your light therapy box while you are eating breakfast, reading the newspaper, working on your computer, playing an instrument, watching the television, putting on your makeup or reading a book.

Light therapy may sound expensive; however you can actually purchase a light box and perform regular light therapy treatments at home.  With the North Star 10,000 you only need to be within in 24 inches from it to be effective, it gives you plenty of room to multi task while you get your treatment.

Seasonal Affective Disorder and Alcohol

Tuesday, May 25th, 2010

Seasonal Affective Disorder is a type of depression which usually occurs during the winter months.  If you are suffering from Seasonal Affective Disorder, you might be better off to avoid alcohol.  Even a little alcohol could affect your SAD symptoms and make them worse. Symptoms can get worse if they are left untreated and if substance abuse is added.

While most people can drink a glass of wine or have a cocktail in the evening, those who struggle from seasonal affective disorder may have a different experience.  There are many reasons that alcohol can create problems for seasonal affective disorder sufferers.  Foremost, it could be dangerous with the medications they are taking.  Second, alcohol is a depressant and this can make depression and anxiety worse.  A person’s judgment and inhibitions can also be affected by alcohol.  It can have a negative impact on their quality of sleep and can also worsen health problems.  Therefore, those that suffer from seasonal affective disorder will find it more difficult to manage SAD if they are consuming alcohol.

Check with your doctor as well, if you are taking medications there is a high probability that you shouldn’t be drinking alcohol while taking them.

What Puts You at Risk for SAD?

Monday, May 24th, 2010

Many seasonal affective disorder suffers might wonder why they are affected by this disorder.  It is important to understand what this disorder is and why it affects so many people, because if you have SAD you will most likely develop depression like symptoms every winter season.  Although many people do develop this condition, some are more at risk than others for being diagnosed with SAD. It depends a lot on your sex, geographic location and genetics.

According to research, more females are diagnosed with SAD than males.  This does not mean that men do not get SAD it simply means that development of SAD is more rare in men.  However, if a male does develop SAD, studies indicate that their symptoms will be worse.

Where you live influences how likely you are to develop SAD because development of the disease depends on sunlight and weather.  SAD appears to be more common among people who live far north or south of the equator, think states that usually have snow during the winter months. This may be due to decreased sunlight during the winter, and the longer days of summer.

All mental illnesses usually involve some sort of family history.  As with other types of depression, studies do show that if SAD runs in the family, than you are more likely to develop the disease than someone who does not have relatives with the condition.

Seasonal Affective Disorder in the Elderly

Tuesday, May 18th, 2010

How old you are has a lot to do with how much you sleep but also when you get that sleep. Babies sleep most of the time, little kids often wake up early, teenagers sleep past noon, and older people seem to sleep less.

The elderly are affected by depression due to changes in their lives, such as death of a loved one or isolation. Seasonal affective disorder is one type of depression that can affect the elderly, especially those who are housebound. While the most common form of seasonal affective disorder occurs during the fall and winter months, rare forms can happen during the spring and summer months.

Seasonal affective disorder is thought to be caused by a lack of ambient light, changes in body temperature or issues with hormone regulation. Elderly patients, who do not go outside often, especially during the fall and winter months, are susceptible. Also, seasonal affective disorder can develop into major depression.

Seasonal affective disorder is most often seen in the elderly during the fall and winter months. Symptoms include social withdrawal, decreased energy and concentration, lethargic movement, carbohydrate cravings, increased sleep, excessive daytime sleepiness, decreased interest in activities and increased appetite with weight gain.

If you find as you get older that your sleep pattern changes, you shouldn’t automatically assume that there’s a problem. As long as you’re otherwise healthy and you’re getting adequate sleep, it could just be your circadian rhythm changing because of age. But talk to your doctor for additional help and advice, or if your side effects don’t go away or get worse.

Light Therapy & Parkinson’s Disease

Monday, May 17th, 2010

Light therapy is most commonly used for treating different kinds of depression.  Recently, light therapy has been used to treat Parkinson’s disease, not just the depression of Parkinson’s patients but to help alleviate motor problems as well.

Bright light stimulates two neurotransmitters that Parkinson’s sufferers lack: serotonin and dopamine. When light reaches a certain level of intensity, it inhibits melatonin which in turn limits the production of dopamine. By limiting the melatonin, in theory, you will have better production and use of dopamine in the brain.

Melatonin, a sleep-related hormone, has also been associated with seasonal affective disorder. Melatonin is made with the amino acid called tryptophan. This hormone has been linked to depression and is produced at higher levels of darkness.  Darkness also increases the production of melatonin. In most cases, this is a good thing. As daylight wanes, most people are preparing to sleep for the night. Darkness helps melatonin to aid in this natural process. In the winter when the days are shorter and darker, melatonin is produced which can then lead to symptoms of seasonal affective disorder.

Serotonin is a neurotransmitter, derived from tryptophan. In order for messages to be transmitted properly, neurotransmitters must pass a sort of baton between these runners. If serotonin levels are low, certain messages cannot be sent correctly or quickly enough through the nervous system. As darkness aids in producing melatonin, sunlight aids in the production of the neurotransmitter serotonin. Without sufficient sunlight, the body may not produce enough serotonin. This can cause a drop in energy levels, a general sense of confusion or “fogginess” and other symptoms typically associated with depression.

Recent case studies of light therapy on Parkinson’s Disease patients involving bright light therapy have had positive results with marked improvement in bradykinesia and rigidity in most patients while being exposed for only ninety minutes. After two weeks the study also showed increased mood, improved sleep, decreased seborrhea, reduced impotence and increased appetite. This change was so significant; some patients were able to have their medication reduced by 50% without the loss of efficiency.

Be Cautious With Blue Light Therapy

Friday, May 14th, 2010

Blue light therapy boxes have been on the market these days.  Most of them advertise for helping with acne, but some advertise for Seasonal Affective Disorder.

The downfall to blue light therapy is there hasn’t been a lot of research on the long-term exposure risks.  Blue light therapy dramatically raises the risk of light-induced retinal damage from light therapy. Macular degeneration is where a person eventually loses the vision in the center of their visual field because the macula – the small central portion of the retina – deteriorates.  It can make it difficult or even impossible to recognize or read faces, although the peripheral vision remains intact.  Optometrists are telling their patients who have or are developing macular degeneration to avoid blue light.

So who should avoid using a blue light box? Those of us who are prone to macular problems due to genetics, nutrition, environment, health habits, diabetes, and aging should avoid using blue light. However, epidemiological evidence has found that even for young adults, in their teens and thirties, a moderate increase in blue light exposure will advance the onset of macular degeneration later in life by 10 years, which would double the likelihood of becoming blind in one’s lifetime. People with fair skin or light-colored eyes can be susceptible to macular degeneration by blue light because they have less melanin in their irises.  Melanin is the substance that gives eyes their color; it also protects the macula from light rays so they don’t cause damage.

Because blue light is not necessary for effective light therapy, it has been recommended that light therapy devices screen out the potentially hazardous blue light wavelengths, and that light therapy devices emitting blue wavelengths of light should not be used until the potential hazard from blue light from light therapy devices is resolved.

Seasonal Affective Disorder in Children

Thursday, May 13th, 2010

Seasonal Affective Disorder in children is a lot less common than in adults. But that is because symptoms are milder and someone what hidden than symptoms in adults.  Research suggests that around 1 million school-age children and teens in the U.S. suffer from SAD.  SAD seems to get worse as people age, but may appear at any stage in a person’s life.

Symptoms in children occur when they are in school, which can be a stressful time anyway.  Parents may mistake symptoms for just problems in school.  It can take years before a child is diagnosed because parents and children don’t recognize the seasonal patterns.  It’s important to keep an eye for warning symptoms that your child is suffering from seasonal affective disorder.

Symptoms include: tiredness or loss of energy, crankiness or irritability – crying in spells, problems in school – including difficulty concentrating and doing schoolwork, oversleeping – including difficulty waking up in the morning, and over eating – especially carbohydrate cravings.

Parents of children and teens with SAD should participate in their treatment.  Learn about the disorder and share it with your child.  They may need help with homework, so make time to help them.  Make sure the child’s teachers know of your child’s situation.  The important thing is to make sure your child is getting the help that they need to feel better.

Light therapy is drug-free treatment for SAD, so it is safe for older children.  Children can sit in front of a light therapy box while eating breakfast, doing homework, watching TV, reading a book or may other options. If you think that your child might be suffering from seasonal affective disorder, it’s important that you contact your child’s physician immediately to discuss diagnosis and treatment.

Diet & Exercise for Seasonal Affective Disorder

Wednesday, May 12th, 2010

For a few years now, doctors and health experts have all advised about the positive effects of exercise.  It provides your body with endorphins that help you be more positive and have a better mood. Diet and exercise are important factors for Seasonal Affective Disorder sufferers.  Although one of the symptoms of SAD is that your appetite and diet change.  Many people have the problem with their appetite increasing and they want to eat more frequently.

While treatments like light therapy work, exercise will help keep you feeling better everyday. Exercising regularly makes a difference.  You only need to exercise for a small amount of time to notice a difference in your life.

The chemicals serotonin, dopamine and norepinephrine, in our brain, affect how we feel, our mood and our energy levels.  Proteins and carbohydrates stimulate production of these chemicals.  Protein helps stabilize blood sugar levels and gives you the amino acid tryptophan which is used by the brain to make serotonin. The production of dopamine is also boosted, which affects movement and to express emotions. Carbohydrates help tryptophan and serotonin production too.

SAD sufferers need a good balance of complex carbohydrates and protein.  Lean proteins such as: lean meat, poultry, fish, eggs, low-fat dairy products, tofu or nuts are helpful in a diet.  Carbohydrates such as whole grains, bread, pasta, rice and potatoes are good as well. You will want to get your daily does of vegetables and fruit in addition.

People can become depressed when they are feeling bored or apathetic. By staying active during the winter months, these feelings can be less noticeable.  For those who suffer from SAD being outdoors or in front of a light box during exercise implies more lighting during the winter months.  It is important to choose an activity that you enjoy and is motivating for you; otherwise you won’t stick to it for long.
