10 Amazing Health Benefits of Sun Exposure

10 Amazing Health Benefits of Sun Exposure

It is not just plants that absorb and metabolize sunlight. Human beings do it too. However, the relationship between sun exposure and health in humans isn’t as straightforward as we might want it to be. Genes are a factor of how humans metabolize sunlight; as is skin type. For instance, people with pale skin that burns easily in the sun are likely to get skin cancer if exposed to too much sun. The timing and duration of exposure is also a crucial factor when it comes to how our bodies metabolize sunlight.

That being said, a number of scientists suggest that the health benefits of moderate sun exposure may in fact outweigh the risks. Researchers from the University of Edinburgh in the UK, for example, specifically point out that the heart-health benefits of sun exposure far outweigh the risk of developing skin cancer. Here are ten huge health benefits of moderate sun exposure you absolutely should know about.

1. Sun exposure lowers blood pressure.

In a landmark study, a group of researchers at the University of Edinburgh found that a compound called nitric oxide that helps lower blood pressure is released into the blood vessels as soon as sunlight touches the skin. This finding was important because until then it was thought that sunlight’s only health benefits to humans was to stimulate production of vitamin D. Richard Weller, Senior Lecturer in Dermatology, and colleagues, however, found that sun exposure can not only improve health, but also prolong life. That’s because the benefits of lower blood pressure include cutting risk of heart attacks and strokes. These benefits, says, Weller “far outweigh the risk of getting skin cancer.”

2. Sun exposure improves bone health.

It is a well known fact that vitamin D stimulates the absorption of bone-strengthening calcium and phosphorus in the body. However, emerging research also indicates there is a direct correlation between bone density and vitamin D3. Vitamin D3 is a fat-soluble vitamin formed during the process of Vitamin D manufacture when sunlight hits the skin. It regulates calcium absorption. When you have higher levels of vitamin D3 in your blood, you are at a lower risk of suffering fractures of virtually all types. On the other hand, lower levels of vitamin D3 in the blood are associated with higher rate of all types of fractures. This is why sun exposure is especially important for bone health in older adults.

3. Sun exposure improves brain function.

Aside from promoting bone health and regulating vital calcium levels, scientists have now linked vitamin D with a number of functions throughout the body, including the functioning of the brain. One study led by neuroscientist David Llewellyn of the University of Cambridge, assessed vitamin D levels in more than 1,700 men and women from England, aged 65 or older and found that cognitive function reduced the lower the subjects’ vitamin D levels were. However, more studies have found sunlight could help spur nerve cell growth in the hippocampus, which is the part of the brain responsible for forming, organizing and storing of memories.

4. Sun exposure eases mild depression.

Sunlight deprivation can cause a condition called seasonal affective disorder (SAD). SAD is a form of depression common in the winter months. It is also common in people who work long hours in office buildings and hardly get out for some sun. Moderate sun exposure, however, increases levels of natural antidepressants in the brain that can actually help relieve this and other forms of mild depression. That’s because on sunny days the brain produces more serotonin, a mood-lifting chemical, than on darker days.

5. Sun exposure improves sleep quality.

When sunlight hits our eyes, a message is sent to the pineal gland in the brain and production of melatonin (a hormone that makes us drowsy and helps us sleep) is shut down until the sun goes down again. Your body gets a clear signal that it’s no longer night and this helps to maintain a normal circadian rhythm. When it gets dark outside, your body gets the signal again and you feel tired and drowsy at bedtime. Low levels of melatonin production at night due to overproduction during the day has been linked to poor sleep quality, especially in older adults. Ditch the sunglasses early in the morning when you wake up if possible so your body gets the message that it is day and triggers the pineal gland to stop releasing melatonin.

6. Sun exposure lessens Alzheimer’s symptoms.

Clinical research has shown Alzheimer’s patients who are exposed to the sun throughout the day from 9 a.m. to 6 p.m. followed by darkness at night score better on mental exams and improve some aspects of the disease. For example, one study published in the Journal of the American Medical Association found that Alzheimer’s patients exposed to bright light had fewer symptoms of depression, nighttime wakefulness, agitation and lost less function than those exposed to dim daytime lighting. The researchers attributed these improvements to more regular circadian rhythms.

7. Sun exposure heals some skin disorders.

Sunlight promotes healing of skin disorders, such as acne, psoriasis, eczema, jaundice and other fungal skin infections. In one study, for example, a four-week outdoor sunbathing therapy was successfully used to significantly clear symptoms of psoriasis in 84% of subjects. While sun exposure has a therapeutic effect on the skin and sunlight has been successfully used to treat skin disorders, this alternative treatment method should be done under medical supervision to prevent negative side-effects of UV radiation and to ensure the benefits outweigh the risks.

8. Sun exposure boosts growth in children.

This benefit is especially true for infants. Studies reveal the amount of sun exposure in the first few months of a baby’s life has an effect on how tall the child grows. Many cultures around the world recognize this fact and expose children to mild sun to boost growth and height.

9. Sun exposure enhances the immune system.

Sun exposure can help suppress an overactive immune system, which could explain why sunlight is used to treat autoimmune diseases like psoriasis. And since white blood cells increase with sun exposure and they play a key role in fighting diseases and defending the body against infection, moderate sun exposure is very helpful for your immune system.

10. Sun exposure reduces risk of certain cancers.

Vitamin D deficiency increases your risk of many cancers, especially breast and colon cancer. However, eating whole foods and getting some sun can send breast cancer into remission. This connection was first made by Drs. Frank and Cedric Garland from the University of California who observed that the incidence of colon cancer was nearly three times higher in New York than in New Mexico. Subsequent studies have since shown vitamin D supplementation produce a dramatic 60% drop in risk of developing any form of cancer. This confirms the benefits of vitamin D and sun exposure in reducing risk of cancer.

Bottom line:

Sunshine does have its benefits, but it’s still the number one cause of skin cancer. Experts recommend no more than 15 to 20 minutes of direct sunlight daily for a healthy adult. After that, apply sunscreen with a minimum Sun Protection Factor (SPF) of 30. Remember skin color, where you live and how much skin you expose to the sun affect how much vitamin D you can produce.

How to Overcome Boredom

How to Overcome Boredom

Have you ever been bored? Restless? Fidgety? In need of some inspiration?

I have a theory on boredom. I believe that the rate of boredom has increased alongside the pace of technology.

If you think about it, technology has provided us with mobile phones, laptops, Ipads, device after device – all to ultimately fix one problem: boredom.

What is Boredom?

We have become a global nation that feeds on entertainment. We associate ‘living’ with ‘doing’. People now do not know how to sit still, and we feel guilty when we are not doing anything. Today, inactivity has become the ultimate sin.

You might not realize it, but boredom stimulates a form of anxiety and stress. It evokes an emotional state that creates frustration and feeds procrastination.

It’s a desire to be ‘doing something’ or to be ‘entertained’ – it’s a desire for sensory stimulation. What it boils down to is a lack of focus.

If you think about those times when you’re bored, it’s usually because you did not know what to do. So, indecision also plays a big part.

When we are focused on what’s important to us and what we want to achieve, it’s pretty hard to be bored. So, one answer to boredom is to become focused on what you want.

Sometimes It’s Good to Be Bored

If boredom is a desire for sensory stimulation – then what’s the opposite of that? To be content with no stimulation – in other words – to enjoy stillness.

Sometimes, it’s not boredom itself that causes the frustration but the resistance to doing nothing.

Think about it. What would happen if you were to ‘let go’ of the desire to be entertained? You wouldn’t be bored anymore, and you will feel more relaxed!

In my experience, it’s often the most obvious, simplistic solutions that are the most powerful in life. So, when you’re bored, the easiest way to combat this is to enjoy it.

It may sound weird but think of ‘boredom’ as a form of ‘relaxation’. It’s a break from the constant stimulation that 21st-century living provides – constant TVs, mobile phones, radios, internet, emails, phone calls, etc.

Who knows, maybe ‘boredom’ is actually good for us?

Next time you’re ‘feeling bored’ instead of feeding the frustration by frantically looking for something to do, maybe you can sit back, relax, and savor the feeling of having nothing to do.

In this article, I’ll share with you my 3-step strategy on how to overcome boredom.

3-Step Strategy to Overcome Boredom

1. Get Focused

Instead of chasing sensory stimulation at random, focus on what’s really important to you. Focusing on something important helps prevent boredom because it forces you to utilize your time productively.

You should ask yourself: what would make good use of your time? What could you be doing that would contribute to your major goals in life?

Here are a few ideas:

  • Spend some time in quiet contemplation considering what’s important to you.
  • Start that creative project you’ve been talking about for the last few weeks.
  • Brainstorm: think of some ideas for new innovative products or businesses.

2. Kill Procrastination

Boredom is useful in some ways because it gives you the energy and time to do things. It is only a problem if you let it. But if you use it to motivate yourself to be productive, then you can more easily overcome boredom.

So, the next time you’re bored, why not put this good energy to use by ticking off those things that you have been meaning to get done but have been too busy to finish? This also presents a great time for you to clear your to-do list.

Here are some ideas:

  • Do some exercise.
  • Read a book.
  • Learn something new.
  • Call a friend.
  • Get creative (draw, paint, sculpt, create music, write).
  • Do a spring cleaning.
  • Wash the car.
  • Renovate the house.
  • Re-arrange the furniture.
  • Write your shopping list.
  • Water the plants.
  • Walk the dog.
  • Sort out your mail & email.
  • De-clutter (clear out that wardrobe).

3. Enjoy Boredom

If none of the above solutions work, then you can try a different approach. Don’t give in to boredom and instead choose to enjoy it. This doesn’t mean allowing yourself to waste your time being bored. Instead, think of it as your time to relax and re-energize, which will help you be more productive the next time you work.

Contrary to popular belief, we don’t need to be constantly doing things to be productive. In fact, research has shown that people are more productive when they take periods of rest to recharge.[1] Taking breaks once in a while helps boost your performance and can help make you feel more motivated.

So, take some time to relax. You never know, you might even like it.

Final Thoughts

Learning how to overcome boredom may be difficult at the beginning, but it can be easier if you make use of some techniques. You can start with my 3-step strategy on how to overcome boredom and work your way from there. So, ready your mind and make use of these tips, and you will be overcoming boredom in no time.
