I grew up in a country with very little sunlight majority of the year. 8 months of darkness to be exact. 👀 Since I was little I really struggled with the cold and the darkness. And when I was little, my favourite things was running naked in the sun, taking sunbaths as my mum called it. A happy little Suvi.😊☀️ Even though SAD (Seasonal Affective Disorder) is definitely a real thing, not everyone gets that effected by it, but being the kind of person who gets affected by...well, EVERYTHING. People, energies, the moon, the tides...I couldn’t get away from it all quick enough 😁🙋🏼‍♀️ Especially while being sick for such a long time and suffering from depression, winters were a deadly struggle for me. I came to life during summertimes and cocooned, emotionally and physically the rest of the year. I am happier in the sun, I guess I was destined to follow it all my life being named Suvi, meaning summer in Finnish. How ironic is that for a girl being born next to the Arctic Circle 🤷🏼‍♀️ I coconut oiled my way through Europe and Hawaii, not necessarily the smartest way (even though coconut oil does have 10 SPF in it) to go about it but I felt like a child who had been told never ever to eat candy. When you get your hands on it, you sugar load until you get sick. Making up for lost time I guess 😉 I got a little smarter after I got older and after understanding the dangers of over exposure. The word that sums up my twenties. But there are way more benefits (when doing it in a smart way) than there are dangers. So now when I get the opportunity to have the sun touch my skin, I am not going to say no. Ever. Best kind of mornings are the ones where I can let the sun touch as much of my skin and mind as I possibly can. Considering I am not 5 years old, do not live in a bubble or in Europe anymore, full body exposure is sadly out of the question, most of the time 😉 So don’t be afraid of the sun, have a smart relationship with her, get regular skin checks and let her keep you healthy and happy whenever you can! 💯☀️🙏🏻

Below a list of reasons why sunloving should be a part of your daily routine too. A great read snapped from…/avoiding-sun-will-kill-14-proven-…/ 😊

" Keep you face to the sun, and you will never see the shadows." Helen Keller

" A large number of public health messages over the past century have focused on the dangers of too much sun exposure, such as aging, skin cancer and DNA damage. However, in reality, today’s science tells us that exposure to ultraviolet radiation (UVR)in sunlight has many beneficial effects on human health.

What is Sun Exposure?

Planet Earth has been bathing in sunlight for more than 3 billion years.

As life forms evolved in the ocean they were exposed to sunlight. Eventually, early life learned to make carbohydrates using sunlight as their energy source.

Given the importance of sunlight for life on this planet, it makes sense that all lifeforms, including humans, have evolved to use the power of the sun to their advantage.

Humans have a long history of using sunlight therapy that dates back to the ancient Greeks. Today, sunlight therapy is referred to as heliotherapy.

We instinctively think people with a tan look healthier. A tan is simply the body’s way of protecting itself from the power of the sun’s rays.

Hopefully, after reading the following benefits of sun exposure, you will start to appreciate the powerful effect that the sun can have on your health.

It’s important to note, that whenever a study shows an association with low vitamin D, all we really know from that is that people aren’t getting enough sun. Vitamin D is a good measure of sun exposure on your body.

Circulating vitamin D levels provide a surrogate measure of sun exposure and that it is the other molecules and pathways induced by sun exposure, rather than vitamin D-driven processes, that explain many of the benefits often attributed to vitamin D.

Therefore, if you take vitamin D, you won’t prevent many of the risks associated with lower vitamin D. The safest way to prevent these risks is to actually get sun.

Sun Exposure Decreases Risk of Dying

In southern Sweden, there was a 2X increased risk of death among those who avoided sun exposure compared with the highest sun exposure group.

Nonsmokers who avoided sun exposure had a life expectancy similar to smokers in the highest sun exposure group, indicating that avoidance of sun exposure is a risk factor as significant as smoking. Compared to the highest sun exposure group, life expectancy of avoiders of sun exposure was reduced by 0.6-2.1 years.

Top Health Benefits of Sun Exposure

1) Increases Vitamin D Levels

The best-known benefit of sunlight is its ability to boost the body’s vitamin D supply.

Vitamin D is synthesized in the skin through a photosynthetic reaction triggered by exposure to UVB radiation.

Most cases of vitamin D deficiency are due to lack of outdoor sun exposure.

At least 1,000 different genes, governing virtually every tissue in the body, are regulated by the active form of vitamin .

Vitamin D accumulates in cells of the intestines, where it enhances calcium and phosphorus absorption, controlling the flow of calcium into and out of bones. Thus, adequate vitamin D production through sun exposure is vital for healthy bones.

Without enough vitamin D, bones will not form properly. In children, this deficiency is called rickets, a disease that retards growth and causes skeletal deformities, such as bowed legs.

Sunbathing has been recommended for centuries as an effective treatment for rickets.

Low vitamin D levels cause and worsen osteoporosis and osteomalacia (painful bone disease) in both men and women.

As if this weren’t compelling enough, a recent study showed that low vitamin D levels from sun avoidance increase all-cause mortality.

1.1) Ideal Vitamin D levels

At risk of Vitamin D deficiency: Serum 25OHD less than 30 nmol/L (12 ng/mL).

At risk of Vitamin D inadequacy: Serum 25OHD 30-49 nmol/L (12-19 ng/mL) .

Sufficient in Vitamin D: Serum 25OHD 50-125 nmol/L (20-50 ng/mL) .

Possibly too Much Vitamin D: Serum 25OHD greater than 125 nmol/L (50 ng/mL).

2) Sets Circadian Rhythm (Important!)

Studies published in the ’70s showed that part of the brain (the hypothalamus), the suprachiasmatic nucleus (SCN), functions as the core circadian pacemaker in mammals. Basically, the SCN helps your body tell the time of day.

The SCN receives its messages from the eye. These messages will depend on how much light the eye is being exposed to.

So, your body’s key way of telling the time of day will depend on how much light your eyes receive at certain times of the day.

This is very important for your health. Studies show that having a good circadian rhythm is important for the regulation of sleep-wake cycles, hormone release, body temperature and other important bodily functions.

Getting enough sunlight during the daytime is essential for good sleep. Getting enough light increases night-time melatonin levels. You might also find you go to bed earlier.

Humans are most sensitive to light stimuli during the night. As a result, just as important for entraining your circadian rhythm as getting sunlight in the morning is avoiding artificial light at night.

This is why I use blue blocking glasses after sunset. These Swanick glasses are better for social settings.

3) May Protect Against Cancer

Although skin cancer has been associated with too much UVR exposure, especially in areas of the world with a damaged ozone layer, a number of other cancers could result from too little sun.

For example, those who live in places with less sun (e.g high latitudes) are at higher risk of dying from breast, ovarian, colon, pancreatic, prostate, and other cancers.

One study investigated the impact that vitamin D supplementation has on cancer rates. Results showered that taking 2-4 times the daily recommended intake of vitamin D3 (200-600 IU) and calcium resulted in a 50-77% reduction in expected cancer rates.

Ironically, high sun exposure increases survival rates in patients with early-stage melanoma.

Similarly, occupational exposure to sunlight lowers risk of skin cancers.

Most skin cancers occur on parts of the body that are covered by clothes.

4) Can Protect Against Heart Disease and Lower Blood Pressure

Vitamin D deficiency links to cardiovascular disease can be found in a number of studies demonstrating a 30% to 50% higher cardiovascular morbidity and mortality associated with reduced sun exposure caused by changes in season or latitude.

Conversely, the lowest rates of heart disease are found in the sun-drenched Mediterranean coast and in southern versus northern European countries. Cardiac death has been reported to be the highest during the winter months.

A number of studies have attempted to correlate vitamin D3 with cardiovascular events. Heart attack patients had lower mean D3 concentrations than control subjects. There was a 57% reduced risk for those above compared with those below the median of D.

Rates of high blood pressure correlate with latitude (i.e. less near the equator) and generally rise in winter.

One study exposed a group of high blood pressured adults to a full spectrum tanning bed. After three months, participants had an average 180% increase in their Vitamin D levels. They also had an average 6 mm Hg decrease in their systolic and diastolic blood pressures.

The blood pressure-lowering effect of sunlight might be due to its ability to increase nitric oxide in the body.

Active D/Calcitriol normalizes the impaired heart contractility observed in experimental vitamin D deficience.

Calcitriol regulates heart muscle production and prevents thrombus formation and cell adhesion.

Calcitriol is known to suppress the synthesis and secretion of atrial natriuretic peptide and increases matrix Gla protein, a protein that protects against arterial calcification.

Having lower vitamin D increases PTH, which has many detrimental effects on the heart.

There are many mechanisms by which low calcitriol and high PTH harm your heart (R).

5) Makes You Happier and Combats Depression and SAD

The 3 main mechanisms by which sun benefits mood is by the serotonin and dopamine system and vitamin D.

Sun and Serotonin

One study found that sun exposure increases levels of serotonin and its associated receptors in the brains of healthy men. This is important as relatively high serotonin levels result in better moods and a calm, focused mental outlook.

Sun and Dopamine

Light also increases dopamine release and the dopamine DRD2 receptors.

In Seasonal Affective Disorder (SAD), symptoms include lethargy, worsened reflexes, weight gain and low motivation, which all suggest a less functional dopamine system. In these people, dopamine transporters are reduced in dopamine-rich areas (striatum).

Acute bright light exposure (7,000 lux for 10 min) increased blood flow in dopamine-rich areas of the brain (striatum) in healthy volunteers.

In Parkinson’s, where dopamine neurons are damaged, light exposure (1,000-1,500 lux, 1 hour daily for 2 weeks) improved mood, social activity, and motor function and, in some cases, reduced medication for dopamine replacement by 13%-100%.

Consistent with this, the dopamine DRD2 and DRD3 receptors were greater in people who got more sunshine. Patients with symptomatic SAD also show evidence of altered DA system function, and, compared with healthy controls.

In patients with SAD, neurotransmitter/catecholamine depletion reversed the therapeutic efficacy of bright light, which shows that the effects are mediated by neurotransmitters.

Finally, rodents kept in constant darkness showed increased destruction of neuronal cells that release neurotransmitters — changes that were associated with behavioral alterations indicative of a depres
