15 Reasons Why the Sun is Good for You October 13 2015
Sunshine cheers you up, especially when combined with exercise.
SUNSHINE boosts levels of serotonin - the body's natural happy hormone. That's why we tend to feel happier and more energetic when the sun shines. Regular sun can stave off moderate depression, particularly if combined with exercise, such as a walk in the park. It's also been shown that exercising outdoors creates more endorphins in the body than exercising indoors.
- Your vitamin D levels will go up
- You’ll get more exercise (especially if you’re a child)
- You’ll be happier (especially if your exercise is ‘green’)
- Your concentration will improve
- You may heal faster
Summer is the best time to optimize your UVB exposure which gives you vitamin D. But year round sun exposure gives you endorphins and nitric oxide, all essential to overall wellness and better moods.
A fun history of sunshine.
Sunlight therapy was also used in the UK on children to prevent and treat rickets, a condition which affects bone development. Today it is known that as well as spending some time in sunlight, rickets can easily be prevented by eating a diet that includes vitamin D and calcium. But in the 1930s, many schools got sunlamps, and some taught classes outside. Some animals ended up receiving similar treatment.
Yes, it’s true! Sunlight helps grow healthier Children! January 24 2015
60 percent of children may have suboptimal levels of vitamin D. Prolonged and untreated vitamin D deficiency can affect multiple organs and functions, including bone growth and density, metabolism, heart and immunity, but it rarely causes overt symptoms and often goes unnoticed.
Vitamin D deficiency in childhood can cause skeletal deformities, brittle bones, frequent fractures and lead to premature osteoporosis in later life. However emerging evidence suggests that vitamin D is involved in far more than bone health. Recent studies have found a link between low vitamin D levels and some cancers, heart disease, suppressed immunity and even premature death.
Not Enough Sun Exposure Can Be Risky October 19 2014

Women Who Avoided the Sun Were Twice as Likely to Die From Any Cause as Those Who Had the Greatest Sun Exposure
Getting too much sun can lead to skin cancer. But getting too little sun also can be risky, especially in regions with limited sunshine, a study suggests.
Women who avoided the sun were twice as likely to die from any cause, including skin cancer, as those who had the greatest sun exposure, according to a report in the July issue of the Journal of Internal Medicine. Exposure to sunlight is the main source of vitamin D. Deficiencies in the vitamin have been linked to cardiovascular deaths and more aggressive skin cancers, the researchers said.
The Centers for Disease Control and Prevention recommends avoiding prolonged exposure to the sun and wearing sunscreen with a minimum SPF of 15. The study, conducted in Sweden, suggests sun-exposure guidelines may be too restrictive in northern latitudes.
From 1990 to 1992, sun exposure was assessed in close to 30,000 Swedish women ages 25 to 64. Subjects reported on questionnaires how often they sunbathed, their use of tanning beds, and if they traveled to other regions to swim and sunbathe. Sun exposure was scored from 0 (avoiding sun) to 4 (highest exposure). Other factors, such as a history of malignant melanoma and red hair, a risk factor for melanoma, were recorded.
Melanomas and deaths were subsequently tracked through national registries until 2011. There were 267 cases of melanoma, the most aggressive form of skin cancer, and just over 2,500 deaths from all causes during the study period.
Women who got the most sun had the greatest risk of developing skin cancer. But compared with that group, the risk of dying from all causes was twice as great among the sun avoiders and 40% higher in those with moderate sun exposure.
