You’ve been lied to about the sun in so many ways. Humans need sunlight and all it’s biological benefits for so many reasons that an addiction to sunlight is hardwired into all of us. That’s why it feels so good when the sun hits your skin!
Sunlight is incredibly important for our health in more ways than you might realize. Let’s dive into why catching some rays can be great for you.
Boosting Vitamin D3
When sunlight hits our skin, it triggers the production of vitamin D3, a vital nutrient essential for maintaining strong bones and healthy teeth. This vitamin plays a crucial role in calcium absorption, which is necessary for bone density and strength. Without sufficient vitamin D3, our teeth and bones weaken, leading to conditions such as osteoporosis.
Globally, it is estimated that over one billion people are clinically vitamin D deficient, with even more individuals experiencing suboptimal levels. Specifically, around 24% to 40% of Europeans and up to 35% of North Americans have vitamin D levels that are considered suboptimal, particularly during the winter months. In some regions, particularly those with limited sunlight exposure or higher levels of air pollution, the prevalence of vitamin D deficiency can exceed 50% of the population.
These deficiencies are more pronounced in certain demographic groups, such as older adults, people with darker skin, those living in higher latitudes, and individuals with limited sun exposure due to lifestyle or occupational factors (IOF, 2024) (BMC Public Health, 2024).
Interestingly, one of D3’s significant affects on overall health includes the ability to achieve deep restorative sleep. Without adequate D3, even a full night’s sleep might leave you feeling exhausted. Therefore, getting a little bit of sun each day is crucial for maintaining optimal vitamin D3 levels and, by extension, optimal sleep for your overall health.
The Modern Dilemma: Avoiding the Sun
In the modern world, we’ve begun to villainize the sun, taking extreme measures to avoid its rays. Many of us spend our days indoors, moving from one box (home) to another (car, office, classroom). Even when we step outside, we often cover ourselves head-to-toe, slather on chemical-laden sunblock, and wear sunglasses that block essential light signals from reaching our eyes. This avoidance of sunlight disrupts our natural bio-circadian rhythm and deprives us of the sun’s vital nourishment.
What many people don’t realize is that the sun is essential for virtually all life forms. It is just as nourishing as the food we eat, and no supplement can fully replicate the advantages it offers. The sun plays a pivotal role in regulating our immune system, stimulating anti-inflammatory pathways, inducing nitric oxide production, and supporting healthy metabolic processes—all of which are crucial for dental and bone health, including the prevention of gum disease and tooth decay.
Supporting Oral Health
Vitamin D’s role in maintaining oral health is often underestimated. Adequate levels of vitamin D are crucial for preventing and managing various oral diseases. For instance, low levels of vitamin D have been associated with an increased risk of periodontal diseases, which affect the tissues surrounding the teeth. Periodontitis, a severe form of gum disease, can lead to tooth loss if not properly managed. Vitamin D’s anti-inflammatory properties and its role in calcium metabolism are essential in maintaining healthy gums and supporting the bone structure that keeps our teeth in place.
Moreover, vitamin D deficiency has been linked to the risk of developing recurrent aphthous stomatitis (RAS), a common and painful condition characterized by recurring mouth ulcers. Maintaining sufficient vitamin D levels can reduce the severity and frequency of these ulcers, contributing to better overall oral health.
Making Us Happy
You’ve probably noticed you feel way better on a sunny day than on a cloudy, miserable day. That’s because sunlight helps our brain release serotonin, a chemical that promotes feelings of happiness and calmness. It’s like a natural mood booster. During the darker months of the year, when sunlight exposure is limited, many people experience a dip in their mood and energy levels, often referred to as the "winter blues," or scientifically known now as Seasonal Affective Disorder. Spending time outside in the sun can help combat these effects, keeping your spirits high, mental health controlled and your energy levels steady.
Helping Us Sleep Better
Sunlight also plays a vital role in regulating our sleep-wake cycles. Exposure to sunlight has a significant impact on our body's internal clock, or circadian rhythm. When we get sunlight during the day, it helps our body recognize when it’s time to be awake and when it’s time to sleep. Maintaining optimal vitamin D3 levels is crucial for achieving deep restorative sleep—the kind that leaves you feeling truly rested and rejuvenated. So, getting outside in the morning or afternoon not only helps you fall asleep faster but also enhances the quality of your sleep.
Keeping Our Heart Healthy
Sunlight offers benefits that extend to heart health as well. It helps lower blood pressure by triggering the release of nitric oxide in our blood vessels, reducing the strain on our hearts, and lowering the risk of heart disease. Additionally, optimal vitamin D3 levels play a role in supporting cardiovascular health by helping regulate blood pressure and improving overall heart function. Just a bit of sun can go a long way in keeping your heart healthy and strong.
Strengthening Our Immune System
Our immune system is our body’s defense against germs and sickness, and sunlight can help it function more effectively. By boosting vitamin D3 levels, sunlight enhances our immune response, making us less susceptible to infections and illnesses. Achieving and maintaining optimal levels of vitamin D3 is key to a robust immune system, as it strengthens the body's ability to fight off germs and viruses, keeping you healthier throughout the year.
Healing Skin Conditions
For some people, sunlight can actually help improve certain skin conditions, such as psoriasis and eczema. Controlled sun exposure has therapeutic effects that can alleviate symptoms and improve skin health. Beyond skin conditions, optimal vitamin D3 levels contribute to the healing of chronic wounds and help prevent more severe conditions like infections and certain cancers. While it’s important to avoid overexposure, the right amount of sunlight can be highly beneficial for your skin and overall health.
Enhancing Oral Surgery Outcomes
Vitamin D isn’t just crucial for general health; it also plays a significant role in oral surgery outcomes. Adequate vitamin D levels are necessary for successful osseointegration, the process by which a dental implant anchors to the jawbone. Low vitamin D levels can impair this process, leading to complications and even implant failure. Ensuring optimal vitamin D levels before undergoing dental surgery can enhance bone healing and improve the success rates of procedures like dental implants and bone grafting.
Energizing Our Body
Feeling sluggish? Sunlight can give us a natural energy boost. It helps wake us up and makes us feel more alert and focused. Moreover, optimal vitamin D3 levels enhance metabolic processes, making your body more efficient at converting food into energy. This metabolic boost can lead to weight loss and increased vitality. So, stepping outside for a few minutes not only recharges you mentally but also gives your metabolism a helpful kick, keeping you energized throughout the day.
Improving Eye Health
Sunlight can even help our eyes. Getting some natural light can reduce the risk of nearsightedness in children and young adults. It’s important to enjoy the sun safely, though, and not stare directly at it. A bit of sunlight each day can support eye health and overall vision. The broader benefits of maintaining optimal vitamin D3 levels also extend to preventing vision deterioration, making sunlight an important factor in maintaining healthy eyesight.
Enhancing Cognitive Function
Spending time in the sun can also sharpen our minds. Sunlight exposure improves cognitive function, helping us focus better and think more clearly. This benefit is especially significant for older adults, but everyone can enjoy a mental boost from spending time outdoors. Maintaining optimal vitamin D3 levels is also crucial for cognitive health, helping to stave off cognitive decline and ensuring that our minds stay sharp as we age.
Supporting Healthy Growth in Children
For children, sunlight is vital for healthy growth and development. It helps their bones grow strong and can even prevent some chronic diseases later in life. Ensuring that children maintain optimal vitamin D3 levels is crucial for their developing bones and immune systems. Encouraging kids to play outside in the sun can set them up for a healthier future, with lasting benefits that extend into adulthood.
Embracing the Sun Safely
While sunlight is crucial for health, it’s essential to approach sun exposure with a balanced mindset. Here are some tips to help you safely get the sunlight your body needs:
