Effects of Exercise on Circadian Rhythm of Blood Pressure
Circadian rhythm is a biological process that operates on an approximately 24-hour cy-cle,encompassing various physiological functions including blood pressure,heart rate,and body temperature.The normal circadian rhythm of blood pressure typically exhibits a characteristic"two-peak and one-valley"pattern,which is regulated by a combination of exogenous factors,in-cluding light exposure,exercise,and diet,as well as endogenous factors such as the autonomic nervous system,stress hormones,and clock genes.In recent years,lifestyle factors such as noc-turnal light exposure,shift work,and jet lag have increasingly led to circadian rhythm disrup-tion.The normal circadian rhythm of blood pressure is also often affected,contributing to circa-dian rhythm disorders of blood pressure.Numerous studies indicate that exercise can prevent car-diovascular diseases such as hypertension and heart failure,serving as an important non-pharma-cological strategy to mitigate the disruptions in the circadian rhythm of blood pressure.There-fore,this review will take the factors influencing the circadian rhythm of blood pressure as a starting point,aiming to clarify the possible mechanisms through which exercise participates in regulating the blood pressure circadian rhythm,and to provide a theoretical basis for improving the circadian rhythm disorders of blood pressure through exercise.
