Sunlight can trigger immune system reactions.
People develop itchy eruptions or areas of redness and inflammation on patches of sun-exposed skin.
These reactions typically resolve without treatment.
Photosensitivity, sometimes referred to as a sun allergy, is an immune system reaction that is triggered by sunlight. Photosensitivity reactions include solar urticaria, chemical photosensitization (Ex. from drug reactions), and polymorphous light eruption and are usually characterized by an itchy eruption on patches of sun-exposed skin. People may inherit a tendency to develop these reactions. Certain diseases, such as systemic lupus erythematosus and some porphyrias, also may cause more serious skin reactions to sunlight.
Hives (large, itchy red bumps or welts) that develop after only a few minutes of exposure to sunlight are called solar urticaria. The hives typically last for minutes or hours. This disorder can be difficult to treat, but doctors may prescribe histamine (H1) blockers, antimalarial drugs, corticosteroids, sunscreens, or ultraviolet (UV) light therapy. A person can be prone to developing solar urticaria for a very long time, sometimes indefinitely. People with large affected areas sometimes have headaches and wheezing and feel dizzy, weak, and nauseated.
Over 100 substances, swallowed or applied to the skin, are known to cause sun-induced reactions on the skin. A limited number cause most reactions ( Some Substances That Sensitize the Skin to Sunlight). To treat chemical photosensitivity reactions, corticosteroids are applied to the skin and the substance that is causing the reaction is avoided. There are two types of chemical photosensitivity: phototoxicity and photoallergy.
In phototoxicity, people have pain and develop redness, inflammation, and sometimes brown or blue-gray discoloration in areas of skin that have been exposed to sunlight for a brief period. These symptoms resemble those of sunburn, but the reaction differs from sunburn in that it occurs only after the person has swallowed certain drugs (such as tetracyclines or diuretics) or chemical compounds or has applied them to the skin (such as perfume and coal tar). Some plants (including limes, celery, and parsley) contain compounds called furocoumarins that make some people’s skin more sensitive to the effects of UV light. This reaction is called phytophotodermatitis. All phototoxic reactions appear only on areas of skin that have been exposed to the sun. They usually develop within hours after sun exposure.
In photoallergy, an allergic reaction causes redness, scaling, itching, and sometimes blisters and spots that resemble hives. This type of reaction can be caused by aftershave lotions, sunscreens, and sulfonamides. Substances that cause photoallergy are capable of doing so only after the person has been exposed to both the substance and sunlight (because sunlight is what makes the substance capable of triggering photoallergy). Photoallergic reactions can affect areas of skin that have not been exposed to the sun. They usually develop 24 to 72 hours after sun exposure.
There are no specific tests for photosensitivity reactions. A doctor suspects a photosensitivity reaction when a rash appears only in areas exposed to sunlight. A close review of the person’s medical history, skin symptoms, any diseases, drugs taken by mouth, or substances applied to the skin (such as drugs or cosmetics) may help a doctor pinpoint the cause of the photosensitivity reaction. Doctors may do tests to rule out diseases that are known to make some people susceptible to such reactions (such as systemic lupus erythematosus).
When a rash occurs on an area of skin that has been exposed to the sun and the diagnosis is not clear, doctors may do skin patch tests and reaction reproduction tests that involve exposure to UV light (phototesting) when the person is not using any drugs that cause photosensitivity reactions. These tests may help clarify which type of photosensitivity reaction may be the cause.
Ultraviolet radiation: Invisible rays that are part of the energy that comes from the sun. Ultraviolet radiation can burn the skin and cause skin cancer.
It is often said that the Sun is an “ordinary” star. That’s true in the sense that there are many others similar to it. But there are many more smaller stars than larger ones; the Sun is in the top 10% by mass. The median size of stars in our galaxy is probably less than half the mass of the Sun. A process called fusion heats the Sun. Fusion happens in the core of the Sun. It is very hot there. In fact, the core’s average temperature is around 27,000,000 degrees Fahrenheit. The surface of the Sun is cool compared with the core, only 10,000 degrees Fahrenheit.
This fusion process not only heats the Sun, it makes the sunlight we see here on Earth. This sunlight travels the speed of light which is 186,282 miles per second or 299,792,458 meters per second. This means the light from the Sun takes 8.4 minutes to travel 93 million miles to Earth. If the world’s fastest land animal were to travel that same distance, it would take a cheetah over 151 years to reach the Earth running about 70 mph nonstop!
Ultraviolet radiation: Invisible rays that are part of the energy that comes from the sun. Ultraviolet radiation can burn the skin and cause skin cancer.
Ultraviolet radiation is made up of three types of rays — ultraviolet A, ultraviolet B, and ultraviolet C. Although ultraviolet C is the most dangerous type of ultraviolet light in terms of its potential to harm life on earth, it cannot penetrate earth’s protective ozone layer. Therefore, it poses no threat to human, animal or plant life on earth.
Ultraviolet A and ultraviolet B, on the other hand, do penetrate the ozone layer in attenuated form and reach the surface of the planet. Because ultraviolet A is weaker than ultraviolet B, scientists long blamed ultraviolet B as the sole culprit in causing skin cancer in persons with a history of sunburn and repeated overexposure to ultraviolet radiation. Recent research, however, has also implicated ultraviolet A as a possible cause of skin cancer.
Photosensitivity refers to various symptoms, diseases and conditions caused or aggravated by exposure to sunlight.
- A rash due to photosensitivity is a photodermatosis (plural photodermatoses).
- If the rash is eczematous, it is a photodermatitis.
- A chemical or drug that causes photosensitivity is a photosensitiser.
- A phototoxic reaction to a photosensitiser results in an exaggerated sunburn reaction and no immune reaction is involved.
- A photoallergic reaction to a photosensitiser results in photodermatitis and is due to delayed hypersensitivity reaction.
- A photoexacerbated condition describes a flare of an underlying skin disease on exposure to sunlight.
Photosensitivity is characterized into many groups:
- Polymorphic light eruption (PLE):
PLE generally affects adult females aged 20–40, although it sometimes affects children and males (25%). It is particularly common in places where sun exposure is uncommon, such as Northern Europe, where it is said to affect 10–20% of women holidaying in the Mediterranean area. It is less common in Australasia. It has also been reported to be relatively common at higher altitudes compared to sea level.
PLE can occur in all races and skin phototypes and may be more prevalent in skin of colour than in white skin. There is a genetic tendency to PLE, and it is sometimes associated with or confused with photosensitivity due to lupus erythematosus (which generally is more persistent than PLE).
Genetic factors may be important with many affected individuals reporting a family history of PLE. Native Americans have a hereditary form of PLE (actinic prurigo).
PLE is caused by a delayed hypersensitivity reaction to a compound in the skin that is altered by exposure to ultraviolet radiation (UVR). UVR leads to impaired T cell function and altered production of cytokines in affected individuals. There is a reduction in the normal UV-induced immune suppression in the skin. This has been suggested to be either due to oestrogen or deficiency of vitamin D.
The rash is usually provoked by UVA (in 90%). This means the rash can occur when the sunlight is coming through window glass, and that standard sunscreens may not prevent it. Occasionally, UVB and/or visible light provoke PLE.
PLE may be a rare occurrence in the individual concerned or may occur every time the skin is exposed to sunlight. In most affected individuals, it occurs each spring, provoked by several hours outside on a sunny day. If further sun exposure is avoided, the rash settles in a few days and is gone without a trace within a couple of weeks. It can recur next time the sun shines on the skin. However, if the affected area is exposed to more sun before it has cleared up, the condition tends to get more severe and extensive with longer to heal.
Treatment: One is prevention and avoid sun light when it is out the strongest in ultra-violet rays 12pm to 3pm and always use sunscreen.
The following treatments may reduce the severity of PLE:
- Topical corticosteroid creams to relieve symptoms
- Short course of oral steroids, eg to cover a summer holiday
- Phototherapy: UVB narrowband UVB, or PUVA for several weeks in early spring.

The main difference between osteoarthritis and rheumatoid arthritis is the cause behind the joint symptoms. Osteoarthritis is caused by mechanical wear and tear on joints. Rheumatoid arthritis is an autoimmune disease in which the body’s own immune system attacks the body’s joints.
Arthritis is inflammation of one or more of your joints. (Arthro = joint / itis = inflammation)
The main symptoms of arthritis are joint pain and stiffness, which typically worsen with age. Rheumatoid Arthritis symptoms are joint inflammation that comes from pain, warmth, and swelling. The inflammation is typically symmetrical that is occurring on both sides of the body at the same time (such as hands, wrists, or knees). Other signs of Rheumatoid Arthritis include joint stiffness that is particularly in the AM upon awakening or after periods of inactivity; ongoing fatigue, and low-grade fever. Signs and symptoms come about gradually over years but can come on rapidly for some other people.
The two most common types of arthritis are osteoarthritis and rheumatoid arthritis.
Osteoarthritis is usually caused by normal wear and tear, while rheumatoid arthritis is an autoimmune disorder. Other types of arthritis can be caused by uric acid crystals, infections or even an underlying disease, such as psoriasis or lupus.
Treatments vary depending on the type of arthritis. The main goals of arthritis treatments are to reduce signs or symptoms and improve quality of life through Occupational or Physical Therapy and/or through medications, the old way.
Things that make arthritis worse:
1.) conventional medicine through doctors ordering medications (see Dr. David Brownstein’s website for his Natural Way to Health (with his book) to overcome arthritis). Drugs rarely CURE things. We are trained to believe doctors have all the answers with medications or surgeries in resolving our health problem. NOT THE CASE ALWAYS. It’s unnatural with arthritis and many other diagnoses. Natural therapies and good foods are not taken seriously by enough people in America in regards to helping a condition, like arthritis, or even prevention (which should be your first intervention, don’t wait for the diagnosis).
2.)Infection – check if a bacterial infection started your arthritis. If that is the cause antibiotics, low dose some doctors have given to people in studies and have worked. You would think this would be used more often, at least in testing for before just prescribing anti-inflammatory or analgesics meds. If its infection you need to kill the bacteria and the only way to do that it is with an antibiotic which kills a bacterial infection.
3.)DIET – Too many sugars or chemical preservatives and sweeteners which is in the standard American diet. Processed Foods are BAD. The same foods that cause obesity, diabetes and coronary artery disease can easily cause arthritis. Increase your fruits and nuts in your diet. Vitamin C and E are good for you. Pomegrante extract also.
4.) Dehydration- main causes of arthritis. Many simplify the problem. Your joints need water and if not enough it will cause an auto immune response=inflammation and get worse with processed foods.
5.) Heavy metal toxicity-Mercury, Arsenic and Nickel it includes. Not a fluke and mercury is one of the worst metals to have toxic in your body. Fish is the second worst source of heavy metal food. Few things you can do now, eat tuna occasionally. Silver malcum fillings have your dentist remove. Have your doctor do a heavy metal toxicity test on you if you never had one done and with arthritis.
6.) Low or imbalances of hormones=headache, faster aging, fatigue/lethargy, skin wrinkling sooner in life. Synthetic hormones don’t perform as well in your body and can lead to problems. Female hormones can increase your chance to breast cancer for example.
ACT America and one way to do that is go to Dr. David Brownstein website and check out Reverse your Arthritis to deal with your arthritis naturally and reading his books with bonuses.
Diet and bodyweight impact on arthritis
Experts say that eating a well-balanced diet is vital when you have arthritis. Not only will you be receiving critical nutrients, you will also be either maintaining or arriving more quickly at a healthy bodyweight. If you are overweight you will be adding extra pressure on weight-bearing joints. Many patients have found that losing just a few pounds made a significant difference to their quality of life.
Doctors and nutritionists are more frequently advising arthritis patients to keep sugary and/or fatty foods to a minimum – such as red meat, cream and cheese. You should make sure you are eating plenty of fruit and vegetables, as well as whole grains. Omega-3 essential fatty acids are thought to relieve to some extent the symptoms of arthritis. A common source of Omega-3 fatty acids is oily fish, such as sardines, herring, trout, and salmon.
Many of us tend to place large portions on our plate. If you reduce the size of the portions you may lose weight more effectively. Make sure that vegetables and fruit make up a large part of your portion. Those who need a little help in knowing how to lose weight with knowing the 4 food groups including 3 subgroups to each food group telling you what is lean or leaner or the leanest to eat of that food group. You get this through Dr. Anderson’s book “Dr A’s Habits of Health” and myself as your health coach with you deciding on all the foods you want to eat even foods through my website. Our people in this country need to go back in that direction to decrease disease/illness in percentage; join me and many others who have taken the step. If I can do it so can you it just takes discipline and interest to make America now and in the future a better place to live. The healthier our country gets the better our health care system will turn out for everyone.
“The sciatic nerve extends from the lower back down the back of each leg. Pain affecting this nerve is called sciatica, which usually affects only one side of the lower body.”
“Controlling your blood glucose, blood pressure, and cholesterol can make a huge difference in staying healthy.”

“Regularly consuming more than 25 grams of fructose per day will dramatically increase your risk of dementia and Alzheimer’s disease. Consuming too much fructose will inevitably wreak havoc on your body’s ability to regulate proper insulin levels.”
American Diabetes Association
It’s becoming increasingly clear that the same pathological process that leads to insulin resistance and type 2 diabetes may also hold true for your brain. As you over-indulge on sugar and grains, your brain becomes overwhelmed by the consistently high levels of insulin and eventually shuts down its insulin signaling, leading to impairments in your thinking and memory abilities, and eventually causing permanent brain damage.
Regularly consuming more than 25 grams of fructose per day will dramatically increase your risk of dementia and Alzheimer’s disease. Consuming too much fructose will inevitably wreak havoc on your body’s ability to regulate proper insulin levels.
Although fructose is relatively “low glycemic” on the front end, it reduces the affinity for insulin for its receptor leading to chronic insulin resistance and elevated blood sugar on the back end. So, while you may not notice a steep increase in blood sugar immediately following fructose consumption, it is likely changing your entire endocrine system’s ability to function properly behind the scenes.
Additionally, fructose has other modes of neurotoxicity, including causing damage to the circulatory system upon which the health of your nervous system depends, as well as profoundly changing your brain’s craving mechanism, often resulting in excessive hunger and subsequent consumption of additional empty carbohydrate-based calories.
In one study from UCLA, researchers found that rats fed a fructose-rich and omega-3 fat deficient diet (similar to what is consumed by many Americans) developed both insulin resistance and impaired brain function in just six weeks.
Plus, when your liver is busy processing fructose (which your liver turns into fat), it severely hampers its ability to make cholesterol, an essential building block of your brain crucial to its health. This is yet another important facet that explains how and why excessive fructose consumption is so detrimental to your health. Decreasing fructose intake is one of the most important moves you can take in decreasing the risk of Alzheimer’s disease in your lifetime.
More Tips for Avoiding Alzheimer’s Disease
The beauty of following a healthy diet is that it helps treat and prevent all chronic degenerative diseases, from the common ones like heart disease, cancer, diabetes, obesity and Alzheimer’s to the ones you have never heard of or can’t even pronounce.
The first step is to eat healthy, maintaining exercise balanced with rest and practice healthy habits in addressing Alzheimer’s disease, which is currently at epidemic proportions, with 5.4 million Americans – including one in eight people aged 65 and over – living with the disease.7 By 2050, this is expected to jump to 16 million, and in the next 20 years it is projected that Alzheimer’s will affect one in four Americans. People we need to live healthier if not to help ourselves our future young ones.
In spite of how common memory loss is among Westerners, it is NOT a “normal” part of aging. While even mild “senior moments” may be caused by the same brain lesions associated with Alzheimer’s disease and other forms of dementia, these cognitive changes are by no means inevitable! People who experience very little decline in their cognitive function up until their deaths have been found (post-mortem) to be free of brain lesions, showing that it’s entirely possible to prevent the damage from occurring in the first place and one of the best ways to do this is by leading a healthy lifestyle.
- Fructose. As mentioned, most everyone will benefit from keeping their total fructose consumed to below 25 grams per day.
- Improve Magnesium Levels. There is some exciting preliminary research strongly suggesting a decrease in Alzheimer symptoms with increased levels of magnesium in the brain. Unfortunately most magnesium supplements do not pass the blood brain levels, but a new one, magnesium threonate, appears to and holds some promise for the future for treating this condition.
- Optimize your vitamin D levels with safe sun exposure. Strong links between low levels of vitamin D in Alzheimer’s patients and poor outcomes on cognitive tests have been revealed.Researchers believe that optimal vitamin D levels may enhance the amount of important chemicals in your brain and protect brain cells by increasing the effectiveness of the glial cells in nursing damaged neurons back to health.
Vitamin D may also exert some of its beneficial effects on Alzheimer’s through its anti-inflammatory and immune-boosting properties. Sufficient vitamin D is imperative for proper functioning of your immune system to combat inflammation that is also associated with Alzheimer’s.
- Vitamin B12: According to a small Finnish study recently published in the journal Neurology, people who consume foods rich in B12 may reduce their risk of Alzheimer’s in their later years. For each unit increase in the marker of vitamin B12 (holotranscobalamin) the risk of developing Alzheimer’s was reduced by 2 percent. Very high doses of B vitamins have also been found to treat Alzheimer’s disease and reduce memory loss.
- Eat a nutritious diet, rich in folate. Vegetables, without question, are your best form of folate, and we should all eat plenty of fresh raw veggies every day.
- High-quality animal-based omega-3 fats, such as krill oil. (I recommend avoiding most fish because, although fish is naturally high in omega-3, most fish are now severely contaminated with mercury.) High intake of the omega-3 fats EPA and DHA help by preventing cell damage caused by Alzheimer’s disease, thereby slowing down its progression, and lowering your risk of developing the disorder.
- Avoid and remove mercury from your body. Dental amalgam fillings, which are 50% mercury by weight, are one of the major sources of heavy metal toxicity, however you should be healthy prior to having them removed.
- Avoid aluminum, such as antiperspirants, non-stick cookware, vaccine adjuvants, etc.
- Exercise regularly. It’s been suggested that exercise can trigger a change in the way the amyloid precursor protein is metabolized, thus, slowing down the onset and progression of Alzheimer’s. Exercise also increases levels of the protein PGC-1alpha. Research has also shown that people with Alzheimer’s have less PGC-1alpha in their brains and cells that contain more of the protein produce less of the toxic amyloid protein associated with Alzheimer’s. I would strongly recommend reviewing the Peak Fitness Technique for my specific recommendations.
- Avoid flu vaccinations as most contain both mercury and aluminum, well-known neurotoxic and immunotoxic agents.
- Eat plenty of blueberries. Wild blueberries, which have high anthocyanin and antioxidant content, are known to guard against Alzheimer’s and other neurological diseases.
- Challenge your mind daily. Mental stimulation, especially learning something new, such as learning to play an instrument or a new language, is associated with a decreased risk of Alzheimer’s. Researchers suspect that mental challenge helps to build up your brain, making it less susceptible to the lesions associated with Alzheimer’s disease.
- Avoid anticholinergic and statin drugs. Drugs that block acetylcholine, a nervous system neurotransmitter, have been shown to increase your risk of dementia. These drugs include certain nighttime pain relievers, antihistamines, sleep aids, certain antidepressants, medications to control incontinence, and certain narcotic pain relievers.
Statin drugs are particularly problematic because they suppress the synthesis of cholesterol, deplete your brain of coenzyme Q10 and neurotransmitter precursors, and prevent adequate delivery of essential fatty acids and fat-soluble antioxidants to your brain by inhibiting the production of the indispensable carrier biomolecule known as low-density lipoprotein.
