Maintaining proper hydration may help reduce cardiovascular risks, particularly the increased incidence of heart attacks observed on Monday mornings. Research suggests dehydration contributes to blood thickening, elevated blood pressure, and heightened cardiac strain – factors linked to the circadian-driven surge in heart attack risk during early morning hours. Here’s how hydration intersects with this phenomenon:
### Why Mondays Pose Higher Risks
– : Morning cortisol/adrenaline spikes increase heart rate and blood pressure.
– : Stress hormones rise with the anticipation of work demands.
– : Sleeping without fluid intake concentrates blood, raising clot risk.
### Hydration’s Protective Role
1. :
– Adequate water intake keeps blood less viscous, reducing clotting risks during vulnerable morning hours.
– A Mayo Clinic study found pre-bed hydration thins blood, lowering heart attack/stroke likelihood by 30-50%.
2. :
– Dehydration causes blood vessel constriction and thicker blood, forcing the heart to work harder.
– Drinking 1 glass before baths/showers helps counteract blood pressure spikes.
3. :
– Chronic underhydration elevates serum sodium, a marker associated with heart failure risk.
– NIH research shows adults with optimal hydration (serum sodium
