Does mild physical activity before bedtime alter sleep patterns and heart rate variance in healthy subjects?
Mild physical activity up to 1 hour before bedtime increases heart rate variance and LF/HF ratio during slow-wave sleep, indicating decreased parasympathetic dominance and modified sleep quality.
Bulckaert et al. (2011) studied this question.
