Slow nocturnal body cooling during sleep increases interbeat intervals and is tightly coupled to high‐frequency heart rate variability in healthy men

Slow nocturnal body cooling during sleep increases interbeat intervals and is tightly coupled to high‐frequency heart rate variability in healthy men

Abstract During nocturnal sleep, core body temperature (CBT) decreases and cardiac inter‐beat intervals (IBI) increase. This study used a non‐disturbing cooling intervention during sleep to investigate additional effects of CBT reduction on IBI and heart rate variability. Sleep on a high heat‐capaci...
