1. Aging involves various biological processes, including cellular senescence, DNA damage, and mitochondrial dysfunction.
2. Genetic factors play a role in aging and longevity, with certain genes linked to increased lifespan and resistance to age-related diseases. 3. Healthy mitochondria in our muscles are critical for energy production and longevity. Exercise, especially resistance and aerobic training, boosts mitochondrial function and reduces age-related decline. Aerobic exercise promotes the release of brain-derived neurotrophic factor (BDNF), a protein that supports the growth of new neurons and protects against cognitive decline.
4. Caloric restriction, when done safely, has been shown to extend lifespan by improving metabolic health and reducing oxidative stress. However, extreme restriction is not recommended without proper guidance. 5. A diet rich in antioxidants, omega-3 fatty acids, and polyphenols (found in fruits, vegetables, and nuts) helps protect the brain from oxidative stress and inflammation, both of which contribute to cognitive decline. 6. Hormonal changes play a role in aging, and maintaining hormonal balance can impact longevity.
7. Chronic stress accelerates aging, so stress management is important for slowing down the aging process.
8. Certain supplements, like antioxidants, may have potential benefits in slowing aging. NAD+ (nicotinamide adenine dinucleotide) is a coenzyme that plays a vital role in cellular repair and energy metabolism. NAD+ levels decline with age, and supplementing with precursors like NMN or NR can support healthy aging. 9. Aging is associated with changes in brain structure and function, including reduced neurogenesis and cognitive decline. Factors such as genetics, lifestyle, and chronic health conditions contribute to the risk of neurodegenerative diseases and cognitive decline. Strategies such as regular exercise, a healthy diet, and cognitive stimulation can help reduce the risk of cognitive decline and support brain health. Engaging in cognitive training exercises, such as puzzles, memory games, or learning new skills, can help improve memory, attention, and problem-solving abilities. Lifelong learning is a key strategy for maintaining brain health.
10. Hormesis refers to the beneficial effects of mild stressors, like exercise, intermittent fasting, and cold exposure, which activate cellular repair mechanisms and promote longevity. Autophagy, the process by which cells remove damaged components, is crucial for healthy aging. Fasting, exercise, and certain compounds (like resveratrol) stimulate autophagy, promoting cell repair and longevity.
11. Quality sleep is essential for longevity, as sleep supports cellular repair, immune function, and cognitive health. Prioritising deep sleep and REM sleep helps mitigate the effects of aging on the brain and body.
