Mike introduces the topic of light therapy and how it affects different health issues, based on multiple studies.

• Over 40 studies are referenced, covering nerve regeneration, wrinkles, depression, and thyroid function.
• Heads-up on the upcoming audiobook version of 'Level 5 Vegan'.
• Quick education on light as electromagnetic radiation and its spectrum beyond visible light.

Light spectrum details and the impact of different wavelengths on health are explained.

• The visible light spectrum is only a tiny part of the electromagnetic spectrum.
• Animals can see different parts of the spectrum, like UV and infrared, which humans cannot.
• Infrared light's effects on nerve cells and the potential for neural stimulation and regeneration are highlighted.

Infrared light's benefits for nerve regeneration and potential applications in treating diabetic neuropathy and brain conditions are discussed.

• Infrared light promotes mitochondrial metabolism and nerve regeneration.
• It's been tested for diabetic neuropathy with mixed results.
• Animal studies suggest possible benefits for Alzheimer's and Parkinson's diseases.

Infrared and red light may improve cognitive function and brain oxygen levels.

• Infrared light showed a potential 10% improvement in cognitive function in healthy adults.
• It increased oxygen levels in the brain, which may benefit traumatic brain injury patients.
• There's a need for larger, placebo-controlled studies to confirm these findings.

Red and orange light therapies show improvement in skin rejuvenation, wrinkle reduction, and hair growth.

• Studies show red light therapy aids in skin aging, wrinkle reduction, and scar improvement.
• Red light can stimulate hair growth in conditions like androgenic alopecia and male pattern baldness.
• These therapies increase mitochondrial energy, which may reverse dormant hair follicles.

Red light therapy shows promise in improving thyroid function and reducing medication needs.

• Pilot studies suggest red light therapy may help in reducing the need for thyroid medication.
• Further research is necessary to validate these findings.

Yellow light therapy's effects on skin health are explored, including its potential to reduce hyperpigmentation.

• Yellow light can reduce oxidative stress and support procollagen recovery in artificially aged skin cells.
• It may improve wrinkles and decrease melanin, which could be beneficial for hyperpigmentation disorders.

Green light therapy is found to potentially relieve migraines and has implications for fibromyalgia and emotional well-being.

• Green light therapy has been associated with significant reductions in migraine frequency and intensity.
• It might also be beneficial for fibromyalgia pain relief and improving positive emotions during psychotherapy sessions.

Blue light's role in cognitive performance, alertness, and potential negative effects on sleep are discussed.

• Exposure to blue light can enhance cognitive performance and wakefulness during the day.
• However, it may adversely affect sleep quality and duration if used at night.

White light therapy is an effective treatment for Seasonal Affective Disorder and non-seasonal major depressive disorder.

• Bright white light therapy is recommended for treating SAD with minimal side effects.
• In combination with SSRIs, white light therapy shows significant improvements in depressive symptoms.

Despite its risks, UV light has medical applications in treating skin conditions and potentially reducing viral counts.

• UV light is used therapeutically for skin conditions like psoriasis and vitiligo with positive results.
• A small study suggests UVA light may decrease viral counts in severe COVID-19 cases.
