Healthy Living | By Tony Spratt, Body Coach
In my last article, I shared a concerning statistic: 40% of adolescents today have a mental health diagnosis, and the number is rising. As a father and grandfather, I find this alarming. Our children are our greatest resources: why are so many struggling with anxiety and depression, and why is pharmaceutical intervention the primary solution?
For decades, we have been told that these conditions stem from a "chemical imbalance" in the brain, often linked to low serotonin levels. However, a comprehensive meta-analysis published on Nature.com in July 2022 challenges this notion. The study found no convincing evidence that serotonin deficiencies cause depression, anxiety, or bipolar disorder. If this is the case, why are we still treating children with medications designed to correct a problem that may not exist?
Psychiatric medications come with well-documented side effects, yet they are often prescribed as the first line of defense. While medication may be necessary in some cases, we must ask whether we are addressing the root causes of mental distress or simply masking symptoms.
The Role of Light in Mental and Physical Health
Last month, I shared what I believe to be one of the most important longevity tips: Never miss another sunrise. This isn't just about appreciating beauty; it’s about biology.
Our bodies have an internal clock regulated by the brain's suprachiasmatic nucleus (SCN). This "optical lattice clock" receives signals from sunlight to regulate serotonin, melatonin, dopamine, and other essential hormones. But what happens when the first light we see daily is Blue Light coming from a phone or computer screen instead of the sun?
Exposure to artificial blue light in the morning sends the wrong signals to our brain, disrupting our circadian rhythm. This can lead to sleep disturbances, mood disorders, and even metabolic issues. A practical solution? Step outside for at least 5 minutes (ideally up to 2 hours) each morning. No sunglasses, no sunscreen—just natural light exposure, preferably while grounded to the earth (walking barefoot in the grass).
The Surprising Link Between Light, Weight, and Metabolism
Recent research suggests artificial light exposure may contribute to metabolic disorders. Studies indicate that looking at screens can raise blood sugar and insulin levels—even without eating. This means that blue light exposure could play a role in obesity and metabolic diseases.
We also now understand that melatonin—our body’s most powerful antioxidant—is produced from morning sunlight exposure on both the eyes and skin. This challenges the assumption that melatonin is only relevant for sleep.
Additionally, ultraviolet (UV) light, particularly UVB, is essential for producing vitamin D3. Many people rely on supplements, but direct sunlight exposure is the only natural way to optimize D3 levels above 60 ng/mL (the threshold for immune function optimization). Yet we are told to avoid the sun at all costs—wearing sunglasses, sunscreen, and UV-blocking clothing, which may be depriving us of essential health benefits.
Looking Ahead: A Practical Approach
The next article will explore the connection between blue light toxicity, weight gain, and metabolic disease. More importantly, I’ll discuss practical ways to reduce exposure while still living in a technology-driven world.
I welcome any feedback or questions on optimizing your environment for better health. Let’s start a conversation.
