Most children who take medication for Attention Deficit Hyperactivity Disorder (ADHD) will continue to require it in adolescence, and more than 50% will need to take it as adults. Recent research indicates that this medication can have serious side effects, including dizziness, severe nausea, and suicidal ideation, as well potentially damaging the heart and liver.
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.

Try light therapy. It can treat a number of sleep disorders.
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

Individuals who experience Seasonal Affective Disorder (SAD) develop a depressed state when the seasons change from summer to winter. Once the weather begins to warm back up and days get longer, the symptoms leave. A lack of exposure to daylight and genetics contribute to the disorder.
Symptoms
Seasonal Affective Disorder symptoms include fatigue, depression, a decrease in activity, overeating and a lack of desire to engage in social events.
Time Frame
The depression symptoms typically begin in October and begin to lift around March to April.
Demographics
SAD affects women more often than it affects men, but the symptoms in men are stronger.
Region
The disorder is most common in areas of the world farther from the equator. The days are shorter and therefore, less sunlight is available during the day.
Therapy
Because the cause of the disorder is a lack of daylight, therapy for SAD includes using a special light box 30 minutes a day to increase daylight exposure. Other therapy includes medications, moving to a warmer climate during the winter, learning stress-reduction techniques and eating a healthy diet.

Talk to your doctor if you suspect your child has SAD. Doctors and mental health professionals make a diagnosis of SAD after a careful evaluation and a checkup to ensure that symptoms aren’t due to a medical condition that needs treatment. Tiredness, fatigue, changes in appetite and sleep, and low energy can be signs of other medical problems, such as hypothyroidism, hypoglycemia, or mononucleosis.
When symptoms of SAD first develop, it’s not uncommon for parents to attribute low motivation, energy, and interest to an intentional poor attitude. Learning about SAD can help them understand another possible reason for the changes, easing feelings of blame or impatience with their child or teen.
Parents sometimes are unsure about how to discuss their concerns and observations. The best approach is usually one that’s supportive and nonjudgmental. Try opening the discussion saying something like, “You haven’t seemed yourself lately — you’ve been so sad and grouchy and tired, and you don’t seem to be having much fun. It seems like you’ve been feeling kind of worn out and exhausted — like you just can’t get enough sleep. So, I’ve made an appointment for you to get a checkup. I want to help you to feel better and get back to doing your best and enjoying yourself again.”
Here are a few things you can do if your child or teen has been diagnosed with SAD:
- Participate in your child’s treatment. Ask the doctor how you can best help your child.
- Help your child understand SAD. Learn about the disorder and provide simple explanations. Remember, concentration might be difficult, so it’s unlikely your child will want to read or study much about SAD — if so, just recap the main points.
- Encourage your child to get plenty of exercise and to spend time outdoors. Take a daily walk together.
- Find quality time. Spend a little extra time with your child — nothing special, just something low-key that doesn’t require much energy. Bring home a movie you might enjoy or share a snack together. Your company and caring are important and provide personal contact and a sense of connection.
- Be patient. Don’t expect symptoms to go away immediately. Remember that low motivation, low energy, and low mood are part of SAD — it’s unlikely that your child will respond cheerfully to your efforts to help.
- Help with homework. You may have to temporarily provide hands-on assistance to help your child organize assignments or complete work. Explain that concentration problems are part of SAD and that things will get better again. Kids and teens with SAD may not realize this and worry that they’re incapable of doing the schoolwork. You may also want to talk to the teachers and ask for extensions on assignments until things get better with treatment.
- Help your child to eat right. Encourage your child to avoid loading up on simple carbohydrates and sugary snacks. Provide plenty of whole grains, vegetables, and fruits.
- Establish a sleep routine. Encourage your child to stick to a regular bedtime every day to reap the mental health benefits of daytime light.
- Take it seriously. Don’t put off evaluation if you suspect your child has SAD. If diagnosed, your child should learn about the seasonal pattern of the depression. Talk often about what’s happening, and offer reassurance that things will get better, even though that may seem impossible right now.

Some statistics on your health and sleep.
-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.

Sometimes known as the “winter blues,” people most commonly experience Seasonal Affective Disorder, or SAD, during the fall or winter, when days grow shorter and there is less direct sunlight. Research has supported the use of light therapy in treating SAD, but the precise biochemical relationship between the onset and treatment of SAD remains unclear. There appear to be four key biochemical markers of SAD.
Serotonin
Serotonin is a neurotransmitter in the brain. Levels appear to vary according to the amount of daily sunlight. In “Winter Blues: Everything You Need to Know to Beat Seasonal Affective Disorder,” Dr. Norman Rosenthal summarizes a collection of studies examining the role of serotonin in SAD. Dr. Rosenthal was the first researcher to describe SAD. People with SAD often crave carbohydrates such as sweets and starches; increased carbohydrate consumption appears to raise serotonin levels in the brain, offering support for a relationship with SAD. When people with SAD received light therapy, administering drugs that lowered serotonin levels appeared to undo light therapy treatment gains. For these reasons, antidepressants such as SSRI’s that increase serotonin levels may help to alleviate SAD.
Dopamine
SSRI’s aren’t the only class of antidepressants that affect SAD. Another antidepressant, Bupropion, that has been found to help with SAD, increases levels of dopamine in the brain. Dopamine is a neurotransmitter associated with response to pleasurable experiences.
Norepinephrine
In addition to dopamine, Bupropion increases levels of the neurotransmitter norepinephrine, which may also alleviate symptoms of SAD. Norepinephrine increases secretion of melatonin, which research has been implicated in SAD. Because neurochemical processes are so complex, it’s possible that levels of serotonin, dopamine, and norepinephrine all work in concert in creating or reducing SAD symptoms. All three are influenced by light therapy, the treatment of choice for SAD.
Melatonin
Melatonin is a naturally occurring chemical that helps to regulate the sleep-wake cycle. Secretion of melatonin increases during dark periods and decreases during light exposure. Research has found an association between melatonin levels and SAD, although the precise relationship between the two is not entirely clear.

Fibromyalgia (FM) is a chronic illness, which causes immense physical pain and unbearable fatigue. The word ‘fibromyalgia’ actually means “pain in the fibrous tissues in the body” and as such does not involve the joints, as rheumatoid arthritis and osteoarthritis. It is not classified as a disease as it is a condition that causes many different symptoms, which affect all systems in the body. 90% of those affected are female (especially during child bearing ages) with most patients experiencing symptoms between the ages of twenty and forty. Children and the elderly can also be affected by FM.
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.

Depression occurs in the young and the old and in men and women. We do know that the rate of depression in men is less than for women.
The symptoms that men experience can be different from those that women experience. Symptoms including anger, irritability, and feeling discouraged are more common in men than symptoms of hopelessness or helplessness.
Typical symptoms we associate with depression such as depressed mood may not be present in depression in men. This can make it more difficult to recognize depression in men. Many famous men, including President Abraham Lincoln and Winston Churchill, had depression and still lived successful lives.
Unfortunately, men are not as likely as women to admit to having depression. Even if they do admit to having depression, they may be less likely to seek treatment. Men may stuff their feelings instead of verbalizing them. They may work more, gamble, or use alcohol or drugs to avoid their feelings. Their sleep and or appetite may change. They may suddenly begin talking about divorce or separation.
Women attempt suicide more often than men, but the rate of completed suicide in men is 4 times that of women. Suicide rates peak in mid life and again later in life. Men age 85 and older have the highest suicide rate.
Men want and need to be strong for their families; they don’t want to appear weak or vulnerable. If they are the primary bread winner, they can feel pressure to provide for their dependents. Of course, these general statements can be applied to women as well.
If you suspect a friend or loved one may be depressed, urge them to seek a professional evaluation. There are many options, including medication, therapy or a combination of the two.

Alzheimer’s disease is the most common cause of dementia. Thousands of people die every year from this degenerating disease. Scientists are still no closer to finding a cure, even though research is being carried out daily.
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.

There is a new clinical trial starting at University College London (UCL) that will study whether light therapy could benefit people with epilepsy.
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.
