Higher Dietary Potassium Linked to Better Sleep
Key takeaway
Potassium-rich foods are associated with better sleep quality in observational data (including analyses reporting OR ≈ 1.15), but that does not prove a causal 15% sleep boost for everyone.
- Adults with higher potassium intake more often report good sleep in survey analyses.
- Higher sodium intake tends to track with poorer sleep reports in similar data.
| Finding | Scientific Observation | Impact Magnitude | ||
|---|---|---|---|---|
| Higher potassium | Associated with better sleep quality (NHANES-type analyses) | Modest OR (~1.15 in some models) | ||
| Higher sodium | Associated with poorer sleep reports | Observational only | ||
| Causality | Not established from cross-sectional diet data | Soften “boost” language |
