Circadian Rhythm

NAD+ plays a crucial role in regulating your sleep-wake cycle. Here’s how it affects sleep and how to optimize it. NAD+’s Role in Sleep 1. Circadian Clock Regulation NAD+ levels oscillate with your circadian rhythm: Peak in the morning (active phase) Lowest at night (rest phase) This cycle regulates sleep-wake patterns 2. Sirtuin Activity SIRT1 (a sirtuin) is NAD+-dependent and: Regulates circadian gene expression Helps maintain proper sleep timing Supports sleep quality 3. Melatonin Connection NAD+ metabolism interacts with melatonin production: ...

Poor sleep affects 70 million Americans. Red light therapy may help improve sleep quality through circadian rhythm regulation. How RLT Affects Sleep 1. Melatonin Support Red light (unlike blue light) doesn’t suppress melatonin. Using red light in the evening: Preserves natural melatonin production Supports sleep onset Doesn’t disrupt circadian rhythm 2. Cortisol Regulation Morning RLT helps regulate cortisol: Proper cortisol peak in the morning Gradual decline throughout the day Low cortisol at bedtime = better sleep 3. Relaxation Response Red light therapy promotes relaxation: ...
