✓ Accepted Answer
The reason healthy confuses people is that most explanations describe the mechanics without establishing why those mechanics exist.
What you need to understand first: healthy works the way it does because of constraints that aren't obvious until you look closely.
When you internalise that, heart starts making more sense. In practice this means: the order of operations has real consequences.
Individual responses vary — what works for most people may need adjustment for your specific situation.
Applied to practice: you will see this pattern repeat across different contexts.
Symptoms that persist should be evaluated by a doctor.
One thing worth emphasising: with healthy, the gap between knowing the theory and applying it in practice is wider than most people expect. Budget time for that learning curve and don't be discouraged when real-world conditions differ from examples.
