何謂養生? • 古人云：善養生者，上養神智、中養形態、下養筋骨。 • 通過各種生活型態的調適,颐養生命、增强體質、預防疾病，以期儘量延長無(或少)病痛的時間, 並保持充分的心智與體能, 而能完成各人生命中需要負擔的責任, 及希望達成的目標.

Common chronic conditions as we age- • Musculoskeletal: osteoarthritis, gout, loss of muscle mass • Hormonal/metabolic: diabetes (type II), high cholesterol • Neurological: dementia, Parkinson’s disease, stroke, poor vision, hearing impairment, balance problem • Cardiovascular: heart attack, hypertension, heart failure, irregular heat beats, atherosclerosis • Cancers: colon, lung, prostate, breast, …etc • Lungs: chronic obstructive pulmonary disease, asthma • Urinary: incontinence, urgency • General: deconditioning, medication side effects, weight loss, falls

Risk factors for cardiovascular diseases- • High blood pressure • High blood cholesterol • Diabetes • Smoking • Being overweight • Being physically inactive • Having a family history of early heart disease • Age (55 or older for women) • Uncontrolled stress

Early detection-Cancer Screening 癌症篩檢 1. 乳癌- 乳房攝影檢查：45-69歲婦女、40-44歲二等親曾有乳癌家族史之婦女，每2年1次。 2. 子宮頸癌- 抹片檢查：30歲以上婦女，每年1次，建議婦女們每3年至少接受1次。 3.大腸癌- 糞便潛血檢查：50至未滿75歲民眾，每2年1次。大腸鏡:每10年1次 4. 口腔黏膜檢查：30歲以上有嚼檳榔（含已戒檳榔）或吸菸者、18至未滿30歲有嚼檳榔（含已戒檳榔）原住民，每2年1次。 5. 肝癌篩檢: 每6個月提供B肝帶原和慢性肝炎患者1次腹部超音波和甲型胎兒蛋白檢查，可以降低37％的肝癌死亡率。

Scientific bases for self repair, healing and renewal: • DNA repair: defects associated with accelerated aging and increased risks of cancer • Adult stem cells • Immune surveillance Werner syndrome: a premature aging disorder caused by a genetic defect in DNA repair and replication

How to prevent chronic conditions for a long, healthy, medically uncomplicated life- • Healthy eating habits • Weight management • Physical exercise • Stress reduction • Psychosocial support • A good night’s sleep -Donald Levy, MD, Director of Osher Clinical Center for Complementary and Integrative Medical Therapies at Brigham and Women’s Hospital, quoted from The Harvard Medical School Guide to Tai Chi

Healthy eating habits: • Balanced nutrition • Predominantly plant based, with high fiber content: choose whole grains and beans over processed white grains • Wide variety • Unprocessed food • Moderation: sugar, salt, red meat (saturated animal fat), cholesterol, alcohol, portion • Food safety: additives, preservatives,residual pesticides and herbicides, pollution (bio-concentration) • Slowing the pace of eating

Stress reduction- • Stress: Body’s reaction to a challenge or threat • Fight-or-flight response: activation of the sympathetic nervous system - Blood pressure rises - Breathing becomes more rapid - Heart rate (pulse) rises - Muscles become tense - Digestive system slows down - Immune system goes down - Heightened state of alertness

Medical conditions associated with chronic stress Between 60% and 90% of all physician visits are for stress-related complaints. • arrhythmias, hypertension, increased risk of heart attack and stroke • asthma • irritable bowel syndrome, ulcers • back pain, fatigue, headaches • suppression of the immune system, • increased vulnerability to anxiety and depression, infertility, and hastening the aging process, …etc

Relaxation response (I)- • a physical state of deep rest that changes the physical and emotional responses to stress (e.g., decreases in heart rate, blood pressure, rate of breathing, and muscle tension). • Can be elicited by two essential steps: - Repetition of a word, sound, phrase, prayer, or muscular activity. - Passive disregard of everyday thoughts that inevitably come to mind and the return to your repetition. from Benson Henry Institute for Mind Body Medicine at MGH

Relaxation response (II)- • Mind-body approaches that elicit the RR include: various forms of meditation, repetitive prayer, yoga, tai chi, breathing exercises, progressive muscle relaxation, biofeedback, guided imagery and Qi Gong. • Physiological effects of the RR: decreased oxygen consumption, decreased carbon dioxide elimination, reduced blood pressure, heart and respiration rate, …etc. Dusek et al, Genomic Counter-Stress Changes Induced by the Relaxation Response, PLoS ONE 2008

RR practice enhanced expression of genes associated with energy metabolism, mitochondrial function, insulin secretion and telomere maintenance, and reduced expression of genes linked to inflammatory response and stress-related pathways. -Duseket al, PLoSONE 2008; Bhasin et al, PLoS ONE 2013

Physical exercise- • Moderate intensity: • 道家養生: 內丹: 靜功 (氣功); 動功 (內家拳: 太極拳, 八卦拳, 形意拳) • “Medicinal exercise”: 五禽戲, 八段錦, • Other mind body exercises: Yoga, Pilates, …etc. • 平甩功

Physical exercise- my Tai Chi regimen Daily (~40 min, outdoors) Weekly (3-4 hr, indoors) Basic exercise: stance work, waist turning, deep stretching Meditation 簡易太極32式 24式太極太極刀推手五禽戲,... • 簡易氣功 • 太極熱身功 • 簡易太極32式 • 24式太極 • 太極刀 • 楊式太極85式

Health benefits of Tai Chi- • Improve your balance and bones: flexibility, agility (一舉動, 周身俱要輕靈) • Ease your aches and pains: posture (虛領頂劲, 鬆肩, 含胸拔背; 立身中正而安舒), heightened body awareness, low impact • Strengthen your heart: aerobic, lower blood pressure • Deepen and enrich your breathing: 氣宜鼓盪, deep abdominal breathing • Sharpen your mind:神宜內斂, improve cognitive functions, learn new skills, coordination • Enhance psychological well being and sleep quality: stress reduction (meditation in motion), relaxation(神舒體靜), psychosocial support • Motivation and techniques to remain physically active for life from The Harvard Medical School Guide to Tai Chi, by Peter M. Wayne PhD with Mark L Fuerst

A few more thoughts- • Keep yourself well hydrated. • Kegel exercise: 提肛 • Allergy • Prevention of falls and injuries
