In a recent study conducted during the winter months, adults with ADHD who were treated with light therapy saw significant reductions in many ADHD symptoms, including:

• Inattention
• Impulsive response to stimuli
• Difficulty in sustaining efforts
• Fatigue

Light therapy, which can be administered via a light box involves exposing the person to 10,000 lux light for approximately 30 minutes per day, though exposure times can be increased or decreased as required because individual responsiveness varies. Light therapy is ideally implemented at the time of day when the person usually feels tired or sluggish, though it shouldn’t be done too late at night as this may cause insomnia.

While light therapy shows some promise for treating ADHD in certain individuals, it should be considered a complementary therapy. Ideally, conventional therapy would be implemented year-round and light therapy used as an adjunct treatment during the darker months of fall and winter.

First off, bright light therapy can help for Circadian Rhythm sleep disorder. The principle of light therapy is to imitate bright sunlight and in turn tune the body clock. The light is provided through a light box.

This therapy helps a person maintain a consistent circadian rhythm by sending a properly timed signal of light through the retina of the eye to the brain’s suprachaismatic nucleus, or body clock in the hypothalamus.  Circadian rhythm disturbances respond very well to light therapy, especially bright light (>600 lux). The timing of light therapy also is important as it affects the degree and direction of the rhythm shift. The modes of therapy for different disorders are:

- Light therapy applied in the early evening and nighttime hours will delay the cycle for Advanced Circadian Rhythm Disorder (ACR)

- In the early morning light therapy will stimulate morning alertness and an earlier bedtime for Delayed Circadian Rhythm Disorder (DCR).

-Bimodal Circadian Rhythm Disorder (BCR) may cause a person to be awake during the night, so it is important to avoid light during the night. Use bright light in the mid morning, afternoon, late afternoon and evening while avoiding bright morning light before 9:00 am.

- For sighted people, bright morning light should regulate Non 24-hour Sleep/Wake Cycle symptoms or a free running circadian rhythm

Light therapy should always be used within the proper limits for intensity and time

According to the National Institutes of Health, as many as 7.5 million Americans have psoriasis. It often appears between the ages of 15 and 25, but can develop at any age. Psoriasis treatments aim to interrupt the cycle that increases production of skin cells, thereby reducing inflammation and plaque formation. A new feature on MayoClinic.com focuses on psoriasis treatment options, including topical treatments, light therapy (phototherapy) and oral medications.

Topical Treatments

Used alone, creams and ointments applied to skin can effectively treat mild to moderate psoriasis. When skin disease is more severe, creams are likely to be combined with oral medications or phototherapy.

Light Therapy (Phototherapy)

As the name suggests, this psoriasis treatment uses natural or artificial light. The simplest and easiest form of phototherapy involves exposing the skin to controlled amounts of natural sunlight. Other forms of light therapy include using artificial ultraviolet A (UVA) or ultraviolet B (UVB) light, either alone or in combination with medications.

Oral Medications

Severe psoriasis, or psoriasis that resists other types of treatment, may be treated with oral or injected drugs. Because of severe side effects, some of these medications are used for brief periods and may be alternated with other forms of treatment.

-Only 20% of teenagers get enough sleep (8-10 hours is optimal)

-According to a study done at the University of Michigan states that children who get less than 9.75 hours of sleep are 40% more likely to be overweight by sixth grade.

-The same study shows a direct correlation between the hours of sleep a child gets and their risk for obesity.  The rate for obesity declines with more sleep.

-Adults who sleep less that 7 hours have a high risk for weight gain.

-Only 20% of teens get adequate sleep.  A survey reported that 16% of teens admit to having sleep problems and 28% admit to falling asleep in school.

-New science relates the lack of adequate sleep to increased risk for obesity, depression, alcohol and drug abuse and future cardiovascular disease.

-Adolescents with a history of sleep problems are twice as likely to have ADHD as those without.  Some ADHD medications can exacerbate the sleep quality issues.

-A good night of quality sleep is key to memory and learning.  Our brain takes information in our short term memory and moves to the long term memory during sleep.

How can you and your family get the quality and ideal amount of sleep?

-Set a sleep schedule and do your best to keep it!

-Stay away from caffeine, sugar, and artificial sweeteners, as well as alcohol within 3 hours of bedtime.

-Stay physically active and exercise early in the day.

-Have a relaxing bedtime routine to get your body ready for sleep

-Make breakfast your biggest meal of the day.

-Get lots of bright light in the morning.

-Drink 8-10 eight ounce glasses of water per day.  Even mild dehydration (1/2 cup of your body’s water) could turn into   low-grade chronic fatigue.

-Naps are ok but try to limit them to 15 minutes.

-Go to bed when you are sleepy.  If you don’t fall asleep in 15-20 minutes get up and leave the bedroom.

-Move the television out of the bedroom.

-Keep the bedroom cool and add blankets if you are chilly.

There are many things to try, but the important thing is to keep searching for the combination that is right for you and your body. Get the rejuvenating sleep that your body deserves every night. Try using a light box in the morning when you wake up to help keep your circadian rhythm in check.

So if you are suffering from fibromyalgia syndrome, you may be interested in trying a treatment that is associated with few side effects and positive results. Light therapy has been used for centuries in some countries to help cure chronic and acute pain. It is now available throughout North America to help reduce your fibromyalgia symptoms.

What is Light Therapy?
Light therapy is an alternative therapy used to help relieve a variety of physical illnesses, ranging from chronic pain to depression. Also known as phototherapy, light therapy delivers light beams to various areas of the body in order to trigger hormone release and healing. Practiced by physicians, physical therapists, and psychologists, light therapy uses bright, colored, and low-level forms of light to promote wellbeing.

Who Can Light Therapy Benefit?
Light therapy can offer long-term benefits to those suffering from a variety of health problems or illnesses. It is often used to treat:

• migraine headaches
• arthritis
• soft tissue injuries, including sprains and strains
• seasonal affective disorder
• depression
• sleep disorders

How Can Light Therapy Benefit Fibromyalgia?

Light therapy is particularly useful for treating fibromyalgia syndrome. It can help to reduce:

• muscle pain
• mood disorders and depression
• fatigue
• insomnia

Bright Light Therapy
Bright light therapy is the most commonly used form of light therapy. It is based on the idea that your body is specifically attuned to light. Known as the circadian rhythm, your body’s sleep cycle, energy levels, and mood are all governed by changes in natural light. Bright light therapy uses high-powered fluorescent lights to help trigger the release of specific hormones which will help to restore your body’s natural circadian rhythm and your overall health.

How Effective is Light Therapy?
The effectiveness of light therapy has been debated over the years. However, recent studies now suggest that light therapy is very effective at reducing symptoms of chronic pain, fatigue, headache, and depression. In a study of migraine sufferers, 99% of migraine patients experienced a reduction in the number of headaches they experienced after using light therapy. Another study analyzed light therapy in fibromyalgia sufferers. 66% of sufferers using low light laser therapy experienced a reduction in muscle pain symptoms.

Side Effects of Light Therapy
The side effects caused by light therapy tend to be minimal and temporary. The most common side effects include eye sensitivity and irritation. You may also experience some mild nausea at the beginning of your light therapy sessions. Some patients complain of becoming restless or over-stimulated by light therapy. Reducing the time spent in light therapy can help to eliminate this restlessness

Who Shouldn’t Use Light Therapy?
Light therapy isn’t for everybody. Be sure to speak with your health care provider before trying any form of light therapy.

“There are limited effective treatments for the depressive phase of bipolar disorder,” said Dorothy Sit, M.D., assistant professor of psychiatry and the study’s first author. “While there are treatments that are effective for mania, the major problem is the depression, which can linger so long that it never really goes away.”

In this study, women with bipolar depression were given light boxes and instructed on how to use them at home. The women used the light boxes daily for two-week stretches of 15, 30 and 45 minutes. Some patients responded extremely well to the light therapy, and their symptoms of depression disappeared. The responders to light therapy stayed on the light therapy for an additional three or four months. Four patients received morning light, and five used their light boxes at midday. Participants also continued to take their prescribed medications throughout the study period.

“Three of the women who received morning light initially developed what we call a mixed state, with symptoms of depression and mania that occur all at once — racing thoughts, irritability, sleeplessness, anxiety and low mood,” said Dr. Sit. “But when another group began with midday light therapy, we found a much more stable response.”

Of the nine women treated, six achieved some degree of response, with several reaching full recovery from depressive symptoms. While most attained their best recovery with midday light, a few responded more fully to a final adjustment to morning light. “People with bipolar disorder are exquisitely sensitive to morning light, so this profound effect of morning treatment leading to mixed states is very informative and forces us to ask more questions,” said Dr. Sit. “Did we introduce light too early and disrupt circadian rhythms and sleep patterns?”

People with bipolar disorder are known to be sensitive to changes in outdoor ambient light and to seasonal changes. Researchers are asking whether the risk of suicide in patients with bipolar disorder could be linked to changes in light exposure.

“In our study, 44 percent of patients were full responders, and 22 percent were partial responders,” Dr. Sit and her colleagues write. “Light therapy, therefore, is an attractive and possibly effective augmentation strategy to improve the likelihood of full-treatment response.”

Optimal response was observed with midday light therapy for 45 or 60 minutes daily, noted Dr. Sit.

Treating depression is always important and it can be successfully treated during and after pregnancy. Some antidepressant/anti anxiety medications can be used safely throughout pregnancy and breast feeding.

A drug free way of treating depression during pregnancy is by using a light therapy box.  Bright light therapy is as effective as the antidepressants in depression cure in pregnant women.  Bright light therapy has yielded favorable results for curing depression in pregnancy.  It also is quite safe as it does not have any side effects.  It requires a patient to sit in front of a box for about 30 minutes a day, depending on the patient.

Here are some findings from research on pregnancy and depression:

• Babies born to moms with depression have an increased risk for irritability, less activity and attentiveness and fewer facial expressions.
• There are possible fetal abnormalities when mothers take antidepressants in the first trimester. But there’s not a particular pattern associated with a specific medication or class of medications.

Some specific treatment recommendations include:

• Talk to your provider early if you are planning to conceive. You can talk about the best options for you as an individual.
• Encourage the provider who will deliver your baby and your mental health provider to consult with each other on the best options for you. They will help you understand the risks and benefits of medication versus therapy, etc.
• If you are taking an antidepressant for depression, don’t discontinue or change your dose of medication on your own. This could be dangerous and your symptoms could worsen.
• Use bright light therapy as a drug free option to treat your depression during pregnancy.
• If you have severe depression and are pregnant, you should remain on medication.

Untreated depression during pregnancy has been proven to lead to higher rates of:

• Lower birth weights
• Pre-term labor (depression doubles the risk)
• Increased use of alcohol and drugs to self-medicate

Please have a candid discussion with both your psychiatrist and OB-GYN regarding the benefits, risks and side effects of all medications. If you have been diagnosed with depression and are considering pregnancy, meet with your health providers before you get pregnant. This will provide peace of mind and help to make sure that you and your baby are both as healthy as possible.

The light therapy is mainly used in the advanced stages of Alzheimer’s disease. It is well known for anybody who has been involved with a Alzheimer’s patient that they are at their best early in the mornings. This is because as the disease progresses it affects the part of the brain that controls the circadian rhythms.What the circadian rhythm does is it controls our body clock and the sleep-wake cycle in our brain.

It is common that an Alzheimer’s patient will start to become very agitated in the late afternoon and evening. This is because there eyes become affected, and as the daylight starts to disappear they find it harder to focus on things. They even find it hard to settle during the night and often wandering around the house. This is called sundowning.

The Alzheimer’s light is a helmet which has infrared lights attached to it and it fits onto the head. Scientist first carried out research with this helmet on mice, results proved that it showed great improvement in their learning ability. The mice also showed signs or less agitation at night time.

The trial was for twelve weeks and was tested on men and women between 60 and 70. Half of the participants where given one hour of exposure to bright natural light each morning. The rest where exposed to low light each day. Tests proved that the participants who where given the bright natural light, showed signs of not being as agitated during the day and settling in bed on a night a lot longer than normal.

Tests also proved that the Alzheimer’s light treatment has slowed down the deterioration of the nerve cells in the brain. Which means that an Alzheimer’s patient has been able to live a lot longer in their own home.

Although this is not a cure for alzheimer’s disease, if this treatment can give an Alzheimer’s patient a better way of light then that has got to be a positive thing. Research is still being carried out on the light therapy at the moment.

We have a regular internal sleep/wake cycle that keeps us awake and keeps our sleep time on track. Being exposed to bright light therapy has been shown to improve the sleep/wake cycle in people with sleep problems as well as in people with Alzheimer’s disease.

This study is being done to look at the effects that exposure to a bright light has on daytime sleepiness and night-time sleep in PD. About 30 people with Parkinson’s disease and sleep problems will be in this study. Bright light therapy involves sitting in front of a light box for 1 to 1. 5 hours several times a day for a few weeks.

Three clinic visits (approximately 1 hour each) and two 24-hour stays (including sleep studies) are involved in this study. There are also three 14-day periods in between the clinic visits where activity levels will be measured using an actiwatch, a small, watch-like device that measures movement throughout the day and night, and participants will complete daily sleep logs at home. During one of the 14-day periods, participants will use the light box as instructed at home.

UCL Institute of Neurology and the National Hospital for Neurology and Neurosurgery will be running the study which will involve 100 people who suffer a type of seizure called a complex partial seizure.

In this trial, the UCL researchers aim to find out whether light therapy reduces the number of seizures people experience. A study suggested that people suffered from less seizures on sunny days compared to cloudy days.
