Throughout our week we can be exposed to many stressors on our physical and physiological states; training, work, study and lack of sleep etc.
🧠All of these stressors are perceived and regulated by our nervous system.
❗️Allostatic load is "the wear and tear on the body" which accumulates as an individual is exposed to repeated or chronic stress. (McEwen and Stellar 1993)
3️⃣Three physiological processes cause an increase in allostatic load:
🔹Frequent stress: the magnitude and frequency of response to stress is what determines the level of allostatic load which affects the body.
🔹Failed shut-down: the inability of the body to shut off while stress accelerates and levels in the body exceed normal levels, for example, elevated blood pressure.
🔹Inadequate response: the failure of the body systems to respond to challenge, for example, excess levels of inflammation due to inadequate endogenous glucocorticoid responses.
🤸♂️The importance of homeostasis is to regulate the stress levels encountered on the body to reduce allostatic load.
Simply defined homeostasis is the tendency of a system (in this case the human body) to find stability and balance. Allostasis is a term used in fitness to describe how the body responds and adapts to outside stimuli in order to achieve homeostasis.
🏋️♀️Allostatic load is the sum of all adaptive responses from all outside stimuli that cause the body to deviate from homeostasis.
🤔Your body doesn’t do a good job in separating one stress from another into categories.
When you’re overtraining and not recovering your body perceives that the same as it would getting chased by a tiger. 🏃♂️💨
⚖️Don’t get me wrong you have to train hard, however it’s important to find balance in your life. Sleep well, read, mediation, wind down time, light stretching and relaxing walks are examples of activities that will assist your nervous system in reaching a parasympathetic state and ensure that your body can adapt and recover adequately from external stressors. ✅
⚖️Our goal is to balance the parasympathetic(rest & digest) & sympathetic(fight or flight) states. ♻️
