Exercise Timing

Morning exercise provides additional benefits including increased alertness and improved readiness for the day. The time of day one exercises matters considerably for energy and sleep. The negative timing effect on sleep applies specifically to high-intensity training and not to gentler activities. High-intensity exercise performed within 4 hours of bedtime significantly reduces sleep quality and recovery. Late-night exercise keeps body temperature elevated, disrupting sleep timing and melatonin production. Poor sleep quality caused by late-night exercise further depletes energy reserves. Shifting high-intensity exercise to earlier in the day optimizes sleep quality and recovery.
