STORY AT-A-GLANCE
- Alzheimer’s disease affects over 50 million people worldwide, with poor sleep being a significant risk factor
- Disrupted circadian rhythms are common in Alzheimer’s patients and exacerbate cognitive decline; when your melatonin levels are balanced, you support the synchronization of your brain’s internal clocks, which enhances overall brain function and resilience
- Clinical studies show melatonin supplementation improves cognitive function in Alzheimer’s patients, with decreased melatonin levels serving as an early indicator of the disease
- Melatonin functions as a powerful antioxidant, supports immune system health, aids reproductive success, reduces post-operative pain and has anticancer properties; it also helps maintain the integrity of your blood-brain barrier, an important defense that keeps harmful substances out of your brain
- Natural melatonin production can be optimized through morning sunlight exposure, minimizing evening blue light, maintaining a dark bedroom and reducing stress before bedtime
