Sun Exposure and Type-two Diabetes. Can you reverse your disease?

Diabetes and sun exposure By Marc Sorenson, EdD.

Diabetes is a disease of chronically high blood glucose leading to blindness, nerve damage, heart disease and numerous other maladies.  Diabetes comes in two forms: (1) Type-one, in which there is damage to the islet cells of the pancreas. This is usually due to an autoimmune response, and the damage prevents production of insulin responsible for removing glucose from the blood. (2) Type-two, in which insulin is produced, but blood glucose remain high due to insulin resistance. In this article, we will discuss type-two, which is by far the most common type. As with heart and vascular disease, we must realize a paucity of sunlight is not the cause of either type of diabetes; rather it is caused by deleterious nutrition habits, primarily high meat consumption,[1] [2] [3] sugar consumption,[4] [5] egg consumption,[6] low consumption of fruits and vegetables, and too many fried foods.[7] In the case of type-one, milk consumption may be the most important nutritional factor.[8] However, sunlight may act as a prophylactic against either type of diabetes. With either type of diabetes, it is not usually the diabetes that kills, but other diseases resulting from it.

There are several studies showing a relationship between type-two diabetes mellitus (DM) and sun exposure or UVB exposure.  One paper showed blood-sugar levels were lower during the summer,[9] and another demonstrated exposure to sun lamps increased insulin secretion.[10] It has also been found there is a direct and significant association between low 25(OH)D levels (a surrogate measure for low sun exposure) and increased risk of type-two.[11]

In addition, a meta-analysis produced moderate evidence that recreational sun exposure is associated with a reduced risk of type-two.[12] The study was undertaken because of the observation by researchers showing that although higher 25(OH)D levels were consistently associated with a lower risk of diabetes, supplementing 25(OH)D had shown no such effects. They hypothesized sun exposure could have influences not related to vitamin D, and such seems to have been the case.

Another of the more important investigations showed that women who had “active sun exposure habits” had a 30% reduced risk of type-two.[13]

Diabetes is increasing very rapidly and may someday overwhelm the health-care system. In my opinion, it is the most easily reversed of all degenerative diseases, so this is a tragedy. Proper nutrition, exercise and safe sun exposure can prevent almost all type-two diabetes. At our former resort, about two-thirds of type-two diabetics were free of all medication in two weeks. It is a totally unnecessary disease. If you don’t have it, prevent it. If you have it, reverse it. Start today.

Sunlight and Type-1 Diabetes. Part 1: Great new Research

By Marc Sorenson, EdD, Sunlight Institute…

We have covered the affect to sunlight and diabetes several times, but most of the posts focused on type-2, which is the more common of the two and is becoming a pandemic. Type-2 results when the body produces plenty of insulin, but becomes resistant to its effects, leaving both blood sugar and insulin elevated. Type-1 diabetes is a totally different disease, although high blood sugar is still the result. Both of these diseases, however, correlate to low sunlight exposure. Type-2 is usually caused by atrocious eating habits and obesity, but sunlight deficiency associates with its risk.  Either way, these diseases can lead to blindness, erectile dysfunction, neuropathy, heart disease, hypertension, obesity, kidney disease, amputation of limbs and death. The side-effects of diabetes are usually much more harmful than the diseases themselves.

Type-1 is a disease that afflicts many babies and young people and is sometimes known as “juvenile diabetes.” It is an autoimmune disease, such as multiple sclerosis or rheumatoid arthritis, and is totally different in its cause from type-2, which is caused by atrocious eating habits and obesity. Type one usually happens when the body’s own immune system attacks the pancreas, rendering it useless insofar as insulin production is concerned. The consumption of cow’s milk correlates very closely to contracting the disease by babies and very young children.

Here are some facts regarding the relationship between sunlight and Type-1.  Australian research shows that the incidence of type-1 diabetes correlates closely with latitude; the southernmost part of the country, which has far less availability of sunlight, has about three times the incidence as the northernmost.[i] And in Newfoundland, Canada, an extremely strong inverse correlation exists between sunlight exposure and incidence.[ii] [iii] Similar results have been reported by Dr. Mohr and colleagues, who analyzed the correlation between type-one diabetes and sunlight exposure in 51 regions worldwide and drew the following conclusion: “An association was found between low UVB irradiance [sunlight exposure] and high incidence rates of type 1 childhood diabetes after controlling for per-capita health expenditure. Incidence rates of type 1 diabetes approached zero in regions worldwide with high UVB irradiance, adding new support to the concept of a role of vitamin D in reducing the risk of the disease.”[iv]

The latest study on type-1 and sunlight comes from Denmark, where researchers assessed the association between exposure to sunshine during gestation (pregnancy) and the risk of type 1 diabetes in Danish children at the age of 15 years.[v] The results were that more sunshine during the third gestational trimester was associated with a 40% reduced risk of contracting the disease at age 15.

Sunlight is so important for nearly every aspect of health. Be sure to take advantage of it, as it may be waiting right outside and beckoning you.
