Episode notes
Morning Blood Pressure Spike Raises Short-Term Risk
- Exercise reduces sudden cardiac death, heart attack and stroke risk overall.
- Morning blood-pressure spikes may transiently raise risk by destabilising vulnerable arterial plaque.
Chronotype Matches Lower The Risk
- The UK Biobank found exercise timing interacts with chronotype to affect sudden cardiac death risk.
- People exercising in tune with their chronotype had no increased risk, but those fighting it had small increases.
Exercise When You Will Actually Do It
- Do exercise at the time of day you can consistently do it and build intensity gradually.
- Start with brisk walking to raise fitness before attempting sudden high-intensity activities.
