Light determines our sleep and wake cycle. In most animals and humans, the desire to sleep is broughton by the production of a hormone called melatonin.

Melatonin is made in a tiny gland known as the pineal gland.

In the evening the pineal gland reacts to the low amounts of daylight reaching our eyes and starts toproduce melatonin, which is then released into the blood and flows through the body making us tired.Its production peaks in the middle of the night during our heaviest hours of sleep. In the morning,light shining through the eye reaches the pineal gland which switches offthe production of melatonin,removing the desire to sleep.

for people who have sleep problems you can buy melatonin pills

Fun fact! melatonin has a minty flavour

Colors are visible gentle vitality of sure wavelengths. Photoreceptors within the retina, referred to as cones,translate this energy into colors. The retina accommodates three kinds of cones: one for blue, one for green,and one for r ed. We perceive different colors by combining these colors.

When the colour enters our bodies, it stimulates the pituitary and pineal glands. This in flip impacts themanufacturing of certain hormones, which in turn affect a wide range of physiological processes. This explains

why color has been discovered to have such a direct affect on our thoughts, moods, and conduct-an influencethat many specialists imagine is distinctly separate from psychological and cultural factors

Specific colours can also impact particular diseases. Signs of acute eruptive illnesses equivalent to smallpox andmeasles were relieved when sufferers have been put in a room with purple windows. Melancholiacs additionallyrecovered after a number of hours in such rooms. Ache and melancholy was found to respond properly totherapy using flashing vibrant lights and colored lights. These therapies have been shown to alterneurochemical manufacturing in the brain and this may increasingly account for their optimistic e ffects.

Photostimulation with flashing opaque white or violet lights was found to induce rest, decreasing stress andpower pain. Use of photostimulation, or mind wave synchronization, to assist relaxation and the induction ofhypnosis had been round since 1948. It has been used with the EEG (electroencephalogram) as an adjunct tothe analysis of epilepsy.

The use of Colour as a Therapy is a truly holistic, non -invasive and powerful therapywhich dates backthousands of years; evidence of this can be found in ancient texts from India, China and Egypt.

Seasonal Affective Disorder is also known as winter depression

It is a mood disorder, where people who have normal mental health throughout most of the year experience depressivesymptoms in the winter or, rarely in the summer, spring or autumn, repeatedly.

Difficulty waking up in the morning, morning sickness, oversleeping as well as over eating, and especially a craving forcarbohydrates, are some symptoms that occur when having SAD. Other symptoms include a lack of energy, difficultyconcentrating on completing tasks, and withdrawal from friends, family, and social activities. all of this leads to the depressionand pessimism, which characterize a person suffering from SAD.

Seasonal mood variations are believed to be related to light. An argument for this view is the effectiveness of bright-lighttherapy. SAD is measurably present at latitudes in the Arctic region, such as Finland (64 00N) where the rate of SAD is 9.5%Cloud cover may contribute to the negative effects of SAD.

During the winter, there are lower levels of light, which disrupts the sleep/wake cycle. The sun comes up later in the day duringthe winter, which causes your melatonin levels to diminish at a later time, so during the morning you still you still get up at thesame time. When you wake up in the early hours of the morning, your melatonin levels stay high, which causes you to remain

weary until the sun comes out.

In many species, activity is diminished during the winter months in response to the reduction in available food and thedifficulties of surviving in cold weather. Hibernation is an extreme example, but even species that do not hibernate often exhibitchanges in behaviour during the winter. It has been argued that SAD is an evolved adaption in humans that is a variant orremnant of a hibernation response in some remote ancestor.

There are many different treatments for classic (winter-based) seasonal affective disorder, including light therapy, medication,ionized-air administration, cognitive-behavioural therapy and carefully timed supplementation of the hormone melatonin.

Light therapy or phototherapy includes exposure to daylight or to specific wavelengths of light using lasers, florescent lamps,or very bright, full-spectrum light, called a light box. The light is administered for a prescribed amount of time and, in somecases, at a specific time of day.

Sunlight is known to improve acne. Ultraviolet spectrum cannot be used to as a treatment due to the likely hood of skindamage in the long run.

Light therapy has been suggested for use in healing of wounds. Some believe that low level laser therapy does not appear to beeffective, however others think that it can be effective. Low level light therapy is used clinically in many areas outside theUnited States including Canada, Europe and Asia.

For the purpose of manipulating melatonin levels or timing, light boxes providing intense artificial illumination are effective.These lamps, at a prescribed distance and within peripheral vision, provide up to 10,000 lux to the user 's eyes, without harmfulultraviolet radiation.The production of the hormone melatonin, a sleep regulator, is caused by light and permitted by darknessto some degree.

Light boxes may be effective for the treatment of SAD, however full sunlight is preferred. The United States food and drugadministration doesnt approve of using light boxes to treat SAD, because there have been unclear results in clinical trails,however, light therapy is still the main form of treatment for SAD. Direct sunlight, reflected into the windows of a home oroffice by a computer-controlled mirror device called a heliostat, has also been used as a type of light therapy for the treatingSAD.

Fluorescent light tubes: radiation in the form of soft X-rays escapes out the ends of the tube. This causes a slow clustering of blood cells

and restriction in oxygen flow which makes you tired. another problem with fluorescent lights is pulsation or flicker. The fixturepulsates 60 times a second.

Full spectrum light. John Ott showed in many school studies that when you can change the school lighting f rom incandescent or

fluorescent to full spectrum, students' grade point averages will go up half a g rade point, they will stay out of glasses longer, they will be

less hyperactive, and strangely their dental cavities drop. The reason for this is because it stimulated vitamin D. Full spectrum light

helps depression and the immune system during the winter, and it is the only natural colour to use for viewing artwork and other colour

products.

Full spectrum equivalence to sunlight. If you get six hours of full spectrum light in either fluorescent bulb, fluorescent tube form or

light box form, you are probably close to your 30-minute equivalent of sunlight. If you can get full spectrum lights in your working

environment, you can increase that. You don't have to have direct light.

Incandescent bulbs can not be full spectrum

Usually effects children between 8 and 20 years old

Not all flashing lights and patterns trigger seizures. A flash between 15 -20 flashes per seconds will

most likely cause a seizure.

The mechanism by which flashing lights can cause a seizure is not well understood. people think it is

because the lights can cause nerve cells in those parts of the brain that process visual stimuli to all fire

at once in a synchronized fashion, and this causes a seizure.
