Frequently Asked Questions

Our published guidelines reflect broad consensus from international organizations such as the European Society of Cardiology (ESC) and World Health Organization (WHO). However, individual medical backgrounds differ. Anyone with pre-existing cardiovascular conditions, diabetes, or hypertension must consult their physician before changing their routine.

Nitric oxide (NO) is synthesized in blood vessel walls and serves as the body's primary signaling molecule for vasodilation (relaxing blood vessels). Adequate NO levels support healthy blood pressure, arterial elasticity, muscular oxygen delivery, and sustained physical vitality.

Dehydration reduces blood plasma volume, causing the heart to beat faster and exert greater pressure to circulate oxygenated blood. Maintaining 2.5 to 3 liters of water intake daily preserves optimal fluid dynamics and cellular energy.
