Age Related Rhythm Blunting

Meaning

Age Related Rhythm Blunting describes the progressive reduction in the amplitude and clarity of the body’s natural circadian rhythms that occurs with advancing age. This physiological phenomenon impacts the robust daily oscillations of numerous biological processes, including core body temperature, hormone release, and sleep-wake cycles. Clinically, this blunting contributes significantly to the decline in homeostatic resilience and is a key feature of aging and associated chronic diseases. The diminished difference between peak and trough values compromises the body’s ability to anticipate and adapt to predictable environmental changes.
