The Science of Sleep: Why Rest Matters

Sleep is fundamental to health and well-being. Adults need seven to nine hours nightly for optimal functioning. Poor sleep affects cognition, mood, immune function, and increases chronic disease risk. Establish consistent sleep schedules, even on weekends. Create a relaxing bedtime routine and optimize your sleep environment—keep it dark, quiet, and cool. Limit screen time before bed as blue light disrupts circadian rhythms. Avoid caffeine and heavy meals in the evening. Regular exercise promotes better sleep but avoid vigorous activity close to bedtime. Prioritize sleep as non-negotiable self-care.
