allostasis

Allostasis is the process by which the body maintains stability through change, adapting to new challenges and stressors. Unlike homeostasis, which focuses on keeping internal conditions constant, allostasis involves adjusting various systems to respond to external demands. For example, when faced with stress, the body may release hormones to increase heart rate or alter metabolism. Over time, these adjustments help prepare the body for future challenges, but chronic stress can lead to wear and tear, impacting health. Ultimately, allostasis is crucial for maintaining balance and resilience in a constantly changing environment.
