What it is about
Goal
Improve lifestyle habits to live actively and healthily for most of your life, minimizing time spent in bed before deathObstacles to Goals
- Early failure of a vital organ (due to atherosclerosis, cancer, poor lifestyle habits, etc.) β Death
- Pelvic fracture β Bleeding, organ damage, long bed rest β Higher probability of death from complications (especially with age)
- Sudden fatal accidents or infectious diseases
- While #3 is unfortunate, good lifestyle habits can significantly reduce the risk of #1 and improve #2 to some extent.
- The earlier you start good lifestyle habits, the better the effect. So start now!
Areas to Improve with Good Lifestyle Habits
Organ Health
- Body age ~ Can be viewed as the degree of organ wear
- Factors: Aging degree ~ Total insulin secreted
- Reduce organ stress
- Example: Less insulin secretion - Regular, intermittent, moderate meals
- Quit smoking, moderate alcohol, rest
- Organ DNA damage & repair
- If DNA repair doesn't occur properly after damage β Aging or cancer
- π Helps repair: Autophagy (occurs when hungry), regular biological cycles, sufficient sleep
- π€’ Damages or hinders repair: Stress, poor hygiene, bad air
Vascular Health
- High blood pressure & high blood viscosity
- Blocks and ruptures some brain and organ blood vessels β Brain damage, organ damage
- Prevention
- Manage triglycerides, cholesterol: Avoid high carbs, saturated fats, trans fats
- Manage high blood pressure
Bone Health
- Keep bones & joints strong: Calcium, jogging (provides mild impact between bones & discs for better nutrient absorption)
- Prevent falls & minimize injuries when falling: Balance exercises, strength training
Mental Health
- Mind is part of the body, brain and body interact through chemicals.
- Mental healthπPhysical health
- Ignoring mental health threatens physical health. Mental health is also a consistent health management item.
- Effects of Stress
- Stress β Cortisol decrease β Serotonin secretion inhibition β Depression
- Adrenal glands (organs regulating homeostasis) become exhausted from constant hormone release during stress β Immune decline, fatigue, various burnout symptoms
- Gut and brain are connected: Stress causes gastritis for example
- Stress lowers pain threshold β Feel hurts easily
- Dementia, Memory loss
- Brain exercise to imped them
- Limit social media
Skin Health
- Common skin conditions (eczema, seborrheic dermatitis, etc) are inflammatory responses
- May improve when overall health (immunity) improves
- Body inflammation level decreases when abdominal fat (waist circumference) decreases
