Sleep Optimization & Aerobic Exercise
Reviewed by the Nimbera editorial team · Last updated May 2026
How to use
Target 7-9 hours of sleep per night with consistent wake times. For aerobic exercise, aim for at least 150 minutes per week of moderate-intensity activity (brisk walking, cycling, swimming, jogging). Morning exercise may improve sleep quality and daytime alertness. Limit caffeine after 2 PM and avoid screens 1 hour before bed.
How it works
Sleep is when the glymphatic system clears metabolic waste (including amyloid-beta) from the brain, and memory consolidation occurs. Aerobic exercise increases BDNF (brain-derived neurotrophic factor), promotes neurogenesis in the hippocampus, improves cerebral blood flow, and reduces neuroinflammatory markers.
Where to buy
No products required. A consistent sleep schedule and regular walking are free. Optional: blackout curtains, white noise machine ($20-$50), fitness tracker ($30-$200).

Safety notes
Sleep disorders (sleep apnea, insomnia disorder) may require professional diagnosis and treatment. High-intensity exercise within 2-3 hours of bedtime can disrupt sleep in some individuals - adjust timing as needed.
