Dr. Chris Shows New Light on Health

Have you ever wondered about the role that sunlight plays in your health and biology?

We have too!! And now, you have an awesome guest on the Dr. Chris Show Podcast to tell you all about it and…wait for it…ENLIGHTEN you!! (I’ll show myself out, haha)

Meet Dr. Alexis Cowan, a brilliant doctor who is doing some amazing work on the benefits of light on your biology! This Princeton educated PhD is trying to help you all WAKE UP to the benefits (and harm) of ALL kinds of different light.

How much do you know about light? Do you know the difference between UV light, artificial light, natural light, blue light? Do you know the benefits of sunlight on your growth, your hormones, and your metabolism? How can light help with chronic pain, a subject that Dr. Chris is wildly passionate about exploring?

I can tell you, as a videographer (this is Greg the Vieo Guy, btw!!), light plays a MASSIVE role in the work that I do. Understanding how it operates, how temperature of light affects an image, how light can be used to brighten or dramatize a setting, etc. has been a crucial part of the work that I do.

But I was BLOWN AWAY by the amount of knowledge Dr. Alexis dropped throughout this episode. There is SOOO much great information here, and after learning more from Dr. Alexis, I can tell you, I’ve been going outside everyday first thing in the morning to get my dose of Vitamin D from the vibrant and beautiful sun you’re all so lucky to have!

Light is a fascinating and interesting thing, and it seems like you’re only just beginning to tap into the massive (and FREE) benefit the sun can provide to you. You’ve all been taking the sun for granted, or avoiding it because you’re afraid of sunburn or skin cancer.

But the reality is, the more you get acclimated to the sun by spending more time in it, the better chance you have of protecting yourself from those things!

Conversely, prolonged exposure to artificial light, especially blue light (like what comes out of your screens!) is causing you more harm than good. Something you all kinda know in the back of your heads, but Dr. Alexis takes the time to explain the how and why of it all!

So check out this episode of the pod as Dr. Chris and Dr. Alexis get into all sorts of topics and questions!

Let us know your thoughts, and if you have any questions for us or for Dr. Alexis, leave a comment, and we’ll do our best to…shed some light (wakka wakka!) on the answer!! Ok, enough with the light jokes, I’m not a super bright guy sometimes…ok, seriously, I’m done lol.

Understanding the Different Types of Light

Natural Light

Natural light includes all light that comes from the sun. It’s the most balanced form of light and contains all visible wavelengths, UV rays, and other types of radiation. Natural light is essential for regulating your circadian rhythms, producing Vitamin D, and supporting overall health and well-being. Being in natural light allows you to be in sync with the day-night cycle, which is crucial for various biological processes.

Artificial Light

Artificial light is man-made and comes from sources such as light bulbs, screens, and other electronic devices. While it’s convenient and necessary for modern living, artificial light lacks the natural balance of wavelengths found in sunlight. This type of light can disrupt your circadian rhythm, especially when exposed to it during night hours, affecting your sleep patterns and overall health.

UV Light

Ultraviolet (UV) light is a type of electromagnetic radiation that comes from the sun and artificial sources like tanning beds. There are three types of UV light: UVA, UVB, and UVC. While overexposure can be harmful and lead to skin issues like sunburn and cancer, moderate exposure to UVB rays is essential for Vitamin D production in your skin, which plays a critical role in bone health and immune function.

Blue Light

Blue light is a high-energy visible light that comes from both natural and artificial sources, including the sun and digital screens. While blue light during the day can boost alertness and help maintain a regular circadian rhythm, excessive exposure, especially at night, can harm your sleep quality and lead to eye strain. Managing your exposure to blue light is crucial for maintaining eye health and good sleep patterns.

The Role of Sunlight in Health

Vitamin D Production

One of the most well-known benefits of sunlight is its role in Vitamin D production. When your skin is exposed to UVB radiation, it synthesizes Vitamin D, which is vital for calcium absorption, bone health, and immune function. A lack of adequate sunlight can lead to Vitamin D deficiency, which can cause a host of health issues such as bone disorders and weakened immunity.

Sunlight Exposure and Hormones

Sunlight has a profound impact on your hormone levels. Exposure to natural light helps regulate the production of serotonin, often dubbed the “feel-good” hormone, which enhances your mood and keeps you feeling positive. Conversely, sunlight exposure also influences melatonin production, the hormone responsible for regulating your sleep-wake cycles. Light exposure during the day helps suppress melatonin, while darkness triggers its release, aiding in better sleep.

Impact on Metabolism

Sunlight can affect your metabolism by influencing your circadian rhythms. Proper exposure to natural light helps regulate your internal clock, which, in turn, ensures that your metabolic processes function optimally. Disruptions in your circadian rhythm can lead to metabolic imbalances, affecting appetite, digestion, and overall metabolic rate.

The Benefits of Morning Sunlight

Circadian Rhythm Regulation

Getting sunlight in the morning can significantly help regulate your circadian rhythm. Morning light exposure boosts alertness, mood, and cognitive function throughout the day. It sets the timing of your internal clock, ensuring that you feel awake during the day and sleepy at night. This regularity is key for maintaining optimal health and preventing sleep disorders.

Mental Health Benefits

Morning sunlight can have tremendous benefits for your mental health. Exposure to natural light boosts the production of serotonin, which can help combat feelings of depression and anxiety. Seasonal Affective Disorder (SAD), for example, is often treated with increased exposure to natural light, particularly during the morning hours.

Improving Sleep Patterns

Morning light exposure helps suppress melatonin production during the day, making you more alert and awake. As the day progresses and natural light wanes, melatonin production ramps up, helping you fall asleep more easily at night. This balance is pivotal for maintaining healthy sleep patterns and overall sleep quality.

Potential Harm from Artificial Light Exposure

Blue Light and Eye Strain

Excessive exposure to blue light, especially from screens, can lead to digital eye strain. Symptoms include headaches, blurry vision, and dry eyes. Prolonged exposure can exacerbate these issues, leading to more severe visual discomfort and potential long-term damage.

Impact on Sleep Quality

Exposure to artificial light, particularly blue light, during evening hours can disrupt your sleep quality. Blue light interferes with the production of melatonin, making it harder for you to fall asleep and stay asleep. Poor sleep quality can have a domino effect on your overall health, affecting everything from mood to cognitive function and metabolic processes.

Prolonged Screen Time Effects

Spending long hours in front of screens can have several negative effects. Beyond eye strain and disrupted sleep, prolonged screen time can lead to a sedentary lifestyle, contributing to weight gain and other health issues. It’s important to take regular breaks and manage your screen time to mitigate these risks.

Sunlight and Chronic Pain

Anti-inflammatory Effects

Sunlight exposure can help reduce inflammation in your body. UV light has been shown to modulate your immune system, reducing the production of pro-inflammatory cytokines. This anti-inflammatory effect can be particularly beneficial for people dealing with chronic inflammatory conditions.

Role in Pain Management

Sunlight can play a role in pain management by enhancing your mood and reducing stress, which are often exacerbators of chronic pain. Increased serotonin levels from sunlight exposure can act as natural painkillers, potentially reducing the need for medication.

Dr. Chris’s Research and Insights

Dr. Chris Stepien has delved deeply into how sunlight can affect chronic pain. Through his research and discussions with experts like Dr. Alexis Cowan, he has found that a balanced exposure to sunlight can be a natural therapy for managing chronic pain conditions.
