Do you ever feel overwhelmed by the constant buzz of life in the digital age? If you’re like many of us, juggling the demands of a busy lifestyle can leave you feeling drained and disconnected. It’s time to step back and embrace one of nature’s most underrated healers: sunlight.

This blog draws inspiration from a fascinating me&my health up podcast episode, where host Anthony Hartcher chats with Nathan Siles about the incredible ways sunlight can boost our health and well-being. Nathan, with his personal journey and deep understanding of how light affects our bodies, sheds light on why the sun is more than just a bright spot in the sky.

It’s a source of energy, a mood lifter, and a vital player in keeping our internal clocks ticking correctly. So, let’s dive in and discover how turning our faces to the sun can help us tackle the stress and fatigue of modern life and find a little more joy in our everyday lives.

The Science Behind Sunlight and Health

Sunlight is much more than just a bright light in the sky. It’s a mix of different light frequencies all of which make up the broad spectrum of light. There is visible light which we associate with what we see.

This enables us to see colour and then there is the non-visible spectrum of light  that we can’t see such as UV, cosmic rays, x-rays, radio waves. Some of the light waves in the non-visible spectrum play a special role in keeping us healthy and well. 

UV Rays: The Vitamin D Makers 

UVB rays from the sun onto our skin are essential  to trigger the synthesis of  vitamin D.. They assist in turning cholesterol into vitamin D, which is essential for strong bones, a healthy immune system, and even a good mood.

UVB light is present when the sun advances beyond 30 degrees from the horizon. Without enough UVB sunlight, we can end up with too little vitamin D. This can lead to weak bones and a weaker immune system. 

Infrared Light: The Invisible Healer 

Infrared light is a part of sunlight that we can’t see, but it’s important. It goes deep into our muscles and helps with blood flow, reduces swelling, and helps muscles recover.

Think of it as a warm, soothing type of light that helps heal and relax our bodies from the inside. 

Visible Light: Keeping Our Body Clock in Check 

The sunlight we can see, especially the red light in the morning, helps keep our body clock, or circadian rhythm, on track. This clock controls our sleep, hormone release, and more.

Getting regular morning sunlight keeps our body clock running right, leading to better sleep, a better mood, and balanced hormones. 

The Full Spectrum: All-Round Health Benefits 

The Big Picture: Sunlight is a combination of UV, infrared, and visible light. Together, they work in harmony to support our health in many ways. 

Overall Impact: This blend of light helps with various body functions and plays a big part in our overall health and well-being. 

Vitamin D Synthesis 

Vitamin D Synthesis 

One of the most well-known benefits of sunlight is its role in vitamin D synthesis. When UVB rays from the midday sun strike our skin, they initiate a process that converts cholesterol into vitamin D, a vital nutrient for bone health, immune function, and overall well-being.  

This process is so crucial that a lack of sunlight exposure can lead to deficiencies, impacting various aspects of health. 

Circadian Rhythm Regulation 

Circadian Rhythm

Our bodies operate on a natural 24-hour cycle known as the circadian rhythm, which is significantly influenced by light exposure. Sunlight, particularly in the morning, helps reset this internal clock, promoting better sleep patterns, hormone regulation, and metabolic processes. This rhythm is essential for maintaining mental and physical health. 

Mental Health Benefits of Sunlight 

Mental Health Benefits of Sunlight

Sunlight does more than just brighten our days; it plays a significant role in enhancing our mental health. Here are the key ways which exposure to sunlight can positively impact our mood and cognitive functions: 

Boosts Mood 

Sunlight exposure, especially in the early morning, is linked to improved mood. The natural light helps regulate neurotransmitters like serotonin, often referred to as the ‘feel-good’ hormone, which is crucial for maintaining a positive mood.

Enhances Cognitive Function:

Regular exposure to sunlight can lead to better cognitive function. This includes improved concentration, sharper thinking, and overall mental clarity, making it easier to navigate daily tasks and challenges. 

Reduces Brain Inflammation 

The gentle early morning sunlight (light exposure up to 10 degrees from the horizon), which lacks UV rays, can help reduce inflammation in the brain. This is particularly beneficial in managing and potentially preventing neurodegenerative conditions.

Clears Neurodegenerative Proteins 

Sunlight helps in clearing out proteins that are linked to neurodegenerative diseases. This cleansing effect contributes to the overall health of the brain, supporting its long-term functionality.

Regulates Key Neurotransmitters 

Exposure to sunlight helps in the regulation of crucial neurotransmitters like dopamine and serotonin. These chemicals play vital roles in our mood and behaviour, influencing everything from our happiness to our sleep patterns. 

Skin Health and Cancer Myths 

Sunlights effect in skin health

Contrary to popular belief, moderate sun exposure may not be as harmful to the skin as once thought. While it’s essential to avoid sunburn, regular, safe exposure to sunlight can be beneficial.  

It’s a myth that high vitamin D levels, obtained from sun exposure, are associated with skin cancer. In fact, a balanced exposure to sunlight can contribute to healthy skin and may even play a role in preventing certain skin conditions. 

Role of Sunlight in Cholesterol Management 

Sunlight in Cholesterol Management

Sunlight plays a crucial role in managing cholesterol levels. It helps in the conversion of cholesterol into vital biomolecules, including vitamin D. High levels of LDL cholesterol, often labelled as ‘bad’ cholesterol, can indicate a deficiency in sunlight exposure. By embracing sunlight, we can aid our bodies in maintaining healthy cholesterol levels.


The healing power of sunlight extends far beyond vitamin D synthesis. It’s a natural regulator of our biological clocks, a booster for our mental health, and a crucial element in managing physical health. By understanding and respecting the sun’s role in our lives, we can harness its benefits for optimal health and well-being.

Note: While embracing the benefits of sunlight, it’s important to do so responsibly. Understanding your skin type, the intensity of the sun in your region, and taking precautions to avoid overexposure are essential steps in safely enjoying the sun’s myriad advantages.
