Episode notes
Sleep Disturbance Harms The Heart
- Sleep disturbance is a major risk factor for cardiovascular disease and affects blood pressure and heart rate.
- Disrupting circadian rhythm from time changes can negatively impact overall heart health.
Less Daylight Raises Depression Risk
- Reduced daylight increases rates of depression and undermines healthy habits like exercise and diet.
- Mental health and cardiac health are interconnected, so seasonal darkness can worsen both.
Shift Sleep Gradually Before The Change
- Shift your sleep gradually by 15-minute increments over several days before the clock change to protect your circadian rhythm.
- Use light exposure, short daytime walks, and maintain exercise and healthy eating to offset lost daylight effects.
