Morning light is medicine
Your circadian clock is set by morning sunlight — not evening vibes. Permanent Standard Time keeps sunrise aligned with school, work, and wake times.
- Morning light suppresses melatonin and boosts alertness, mood, and metabolic health.
- Permanent DST pushes winter sunrise past 8am in most states (past 9am in some).
- Sleep societies (AASM, Sleep Research Society, National Sleep Foundation) endorse permanent Standard Time.
- Stanford models found permanent Standard Time could cut obesity and stroke cases more than permanent DST.
