Recent market fluctuations have undoubtedly brought everyone gains in wealth, experience, confusion, and lessons. The market is now entering a "hard mode," and the key at this stage is not chasing trends, but rather reviewing past performance, internalizing the lessons learned, and rebuilding your system. However, before returning to the market, don't ignore systemic risks to your health! Traders over 30 are prone to falling into a dangerous zone of "seemingly fine, but actually overdrawn." Pay close attention to these four key monitoring points: ① CAC+Lp(a) for cardiovascular health ② Low-dose lung CT scan to check for sequelae ③ CGM for blood glucose monitoring (blood glucose fluctuations = decreased decision-making quality) ④ hs-CRP//HRV for quantitative recovery ① Preventing the risk of myocardial infarction—a silent killer among young people Why is it urgent: The incidence of myocardial infarction is significantly increasing among young people, and the "time window" for rescue is extremely short—once an attack occurs, you may only have a few minutes to react. Key Tests: CAC (Coronary Artery Calcification Score) Testing Frequency: Every 5 years after age 30 Risk Threshold: CAC > 100 indicates significant atherosclerosis Follow-up Actions: If elevated → Coronary CT angiography or echocardiography Lp(a) — Lipoprotein(a) Characteristics: Genetically determined, lifestyle changes are almost impossible to alter Risk Threshold: >50 mg/dL significantly increases the risk of atherosclerosis Major Breakthrough: Multiple drugs have entered Phase III clinical trials, showing a reduction of 80%+%, expected to be available in 2026-2027 Why Test Now: Previously, testing didn't provide a cure; now, there are treatments available. The American College of Cardiology has recommended including it in standard physical examinations. High-risk group accounts for approximately 20% — If you fall into this range, knowing this in advance is life-saving information. ② Preventing Latent Lung Lesions — A Legacy Issue After COVID-19 Why is it Easily Overlooked: Many people have small nodules, fibrosis, and micro-inflammation in their lungs after COVID-19, but these are easily missed in routine physical examinations. Testing Protocol: Low-dose lung CT (LDCT) or enhanced CT Testing Frequency: Every 1-2 years High-risk groups: Smoking history/long-term exposure to air pollution/persistent cough → Shorten the testing cycle to annually ③ CGM Blood Glucose Monitoring — Unraveling the Hidden Chain of Cognition-Emotion-Metabolism Why traders need to pay attention to blood sugar: Blood sugar fluctuations directly affect the quality of your decisions. What happens when blood sugar fluctuates drastically? Cognitive level: Sudden drop in blood sugar → Distractibility, slowed reaction time, inability to perform complex reasoning (so-called carbstroke) Emotional level: Unstable blood sugar → Irritability, anxiety, impulsive decision-making (this is why it's easy to place orders randomly when hungry) Energy level: Insulin resistance → Chronic fatigue, difficulty recovering What can CGM monitor: CGM (Continuous Glucose Monitor) is a sensor attached to the arm that automatically records blood sugar every 5 minutes, continuously monitoring for 14 days. It can reveal: ① Metabolic flexibility ② Food sensitivity ③ Real-time correlation between stress and blood sugar Monitoring plan Frequency: Recommended 2-week monitoring every 6 months ④ Systematic review — rebuilding resilience Physiological level — Data-driven monitoring of recovery status: hs-CRP (High-sensitivity C-reactive protein) → Inflammation level HRV (Heart Rate Variability) → Autonomic nervous function (measurable by watches/bracelets/rings) The market's hard mode can be dealt with strategically, but once the body's hard mode is triggered, it's an irreversible loss.
