How Sunshine Supports Longevity and Lowers All-Cause Mortality
Sunshine is more than just a mood booster or a source of warmth. Research shows that regular, moderate exposure to natural sunlight is linked to lower rates of all-cause mortality. That means people who get enough sunshine tend to live longer and healthier lives.
I want to share what science says about the benefits of sunshine and how it supports overall well-being. I’ll also explain how light-based therapies, like those offered at Salt & Light Wellness studios (Riverside, Temecula, Carlsbad, and Murrieta, Ca), can help you enjoy these benefits even when outdoor sun exposure is limited.
Sunshine in natural settings supports physical and mental health.
Why Sunshine Matters for Health and Longevity
Sunlight triggers several important processes in the body. One of the best-known effects is vitamin D production. When UVB rays from the sun hit your skin, your body makes vitamin D, which is essential for bone health, immune function, and inflammation control.
But the benefits of sunshine go beyond vitamin D. Exposure to natural light helps regulate your circadian rhythm, the internal clock that controls sleep and hormone release. Good sleep supports heart health, brain function, and metabolic balance—all factors that influence lifespan.
Studies have found that people with regular, moderate sun exposure have lower risks of heart disease, certain cancers, and autoimmune conditions. These health benefits contribute to lower all-cause mortality, meaning a reduced risk of death from any cause.
How Research Links Sunshine to Lower Mortality Rates
Several large studies have examined the connection between sun exposure and mortality. For example, a Swedish study published in the Journal of Internal Medicine followed over 29,000 women for 20 years. It found that women who avoided sun exposure had a 40% higher risk of death compared to those who spent time in the sun regularly.
Another study in the American Journal of Epidemiology showed that people with higher vitamin D levels, often a result of sun exposure, had lower rates of heart disease and cancer deaths.
These findings suggest that sunshine plays a protective role in overall health. It’s not just about avoiding sunburn or skin damage but about finding a healthy balance that supports your body’s natural functions.
What do we mean when we say "light therapy"?
Sunshine is the ultimate natural source of light therapy and it's important to understand that sunshine has three main therapeutic wavelength ranges that have the greatest impact on health (in particular, what we are discussing today). When natural sunshine is not an option, we can still expose our bodies to these beneficial wavelengths. Most people know that Ultraviolet (UV) light is part of sunshine, but many people are surprised to hear that Red Light (RLT) and Infrared Light (IR) are as well.
At Salt & Light Wellness, we offer services for each of these therapeutic lights in order to capture the myriad of benefits from the sun's rays. By enjoying regular brief exposures in sunbeds, Red Light Therapy, and InfraRed Saunas, individuals can supplement their light exposure indoors and on their schedule. When weather or time doesn't permit, Salt & Light is here to ensure regular therapeutic exposures in a beautiful and relaxing environment.
Sunshine and Mental Well-Being
Sunlight also affects mental health. Exposure to natural light increases serotonin levels, a neurotransmitter that helps regulate mood and reduce anxiety. This is why people often feel happier and more energetic on sunny days.
Seasonal Affective Disorder (SAD) is a type of depression linked to reduced sunlight during winter months. Light therapy, which mimics natural sunlight, is a common treatment for SAD and other mood disorders.
At Salt & Light Wellness, we offer light therapy sessions that provide the benefits of sunshine indoors. These sessions can help improve mood, energy, and sleep quality, especially when outdoor sun exposure is limited.
Light therapy devices can replicate the benefits of natural sunshine indoors.
What The Research Says About How to Safely Enjoy Regular Sunshine
Getting the right amount of sun is key. Too little sun means missing out on health benefits. Too much can increase the risk of skin damage and skin cancer. Here are some tips to enjoy sunshine safely:
Spend 10 to 30 minutes outside daily, depending on your skin type and location.
Indoor exposures can be for as low as 5-10 minutes. Sessions are more efficient because sunning indoors provides a private environment where individuals can expose more or all of their skin, therefore taking in more sunshine per minute.
Avoid peak sun hours (10 a.m. to 4 p.m.) when UV rays are strongest.
Use sunscreen after short sun exposure to protect your skin.
Wear protective clothing and hats if you plan to be outside longer.
Consider light therapy sessions during winter or if you have limited outdoor time.
How Salt & Light Wellness Supports Your Sunlight Needs
For those living in areas with less sun or who want to boost their wellness routine, Salt & Light Wellness offers light-based therapies that mimic the benefits of natural sunlight. Our studios in Temecula, Riverside, Carlsbad, and Murrieta, CA, provide a controlled environment to enjoy the healing power of light.
One of their signature services is the Vitamin D sunbed. This therapy uses advanced light technology to stimulate vitamin D production, improve mood, and support circadian rhythms. It’s a great option for people who want to maintain the benefits of sunshine year-round.
Another service is the Infrared Sauna Therapy, which combines heat and light to promote detoxification, improve circulation, and reduce inflammation. This therapy complements the effects of sunlight by supporting overall body health.
You can learn more about these services and how they fit into a holistic wellness plan on the Salt & Light Wellness website.
The Role of Intentional Wellness Practices with Sunshine
Sunshine works best when combined with other healthy habits. Eating a clean, organic diet rich in antioxidants supports skin health and reduces inflammation. Regular exercise outdoors not only increases sun exposure but also boosts cardiovascular health and mood.
Avoiding synthetic fragrances and harsh cleaners helps reduce chemical exposure that can interfere with your body’s natural healing. Intentional self-care, including mindfulness and stress reduction, enhances the benefits of sunshine by supporting hormonal balance.
Outdoor activities in sunlight enhance physical and mental well-being.
Final Thoughts on Embracing Sunshine for Longevity
Sunshine is a natural, powerful ally for health and longevity. Research shows that moderate sun exposure supports vitamin D production, mental well-being, and lowers the risk of many chronic diseases. This translates into lower all-cause mortality and a better quality of life.
If you can’t get enough natural sunlight, light therapy services like those at Salt & Light Wellness offer a safe and effective alternative. Combining sunshine with clean nutrition, movement, and mindful self-care creates a strong foundation for lasting wellness.
Start by spending a few minutes outside each day or exploring light therapy options. Your body is designed to thrive with light, and embracing sunshine can help you live a longer, healthier life.
