健康专家指出，中年（40至60岁）是采取健康干预措施的理想时期，因为许多与年龄相关的疾病（如心血管疾病、糖尿病、癌症和痴呆症）的风险因素在此阶段就已开始积累[1]。专家建议在中年阶段养成九项小习惯，以预防疾病并延长寿命。
心肺功能是寿命和晚年活跃度的最佳预测指标[1]，因此间隔训练成为首要推荐。社交互动被认为可能是"最重要的健康干预"[1]。此外，摄入发酵食物有助于维持健康的肠道微生物群，而健康的肠道微生物群与健康衰老密切相关[1]。
力量训练和充足蛋白质摄入也至关重要[1]。一般建议为每公斤体重摄入0.8至1.2克蛋白质[1]，这意味着一名68公斤的成人每天应摄入54至81克蛋白质[1]。增加日常活动量同样重要，约每天7000步可显著降低死亡和衰老相关疾病风险[1]。
在预防疾病方面，接种带状疱疹疫苗可将痴呆症风险降低约20%[1]，了解个人家族病史有助于及早识别遗传风险[1]。睡眠方面，2024年研究发现睡眠的规律性比睡眠时长更能预测死亡率[1]，专家建议每晚睡眠7至8小时[1]。
Health experts have identified nine practical habits that people in their 40s and 60s should adopt to extend their lifespan and prevent age-related diseases [1]. Midlife represents a critical window for intervention, as the foundations for many serious conditions—including cardiovascular disease, diabetes, cancer, and dementia—are often established during these years [1].
Among the recommended habits, cardiorespiratory fitness emerges as the strongest predictor of both longevity and active aging in later years [1]. Social engagement may be "the most important health intervention," according to Dr. Ezekiel Emanuel [1]. Regular physical activity, specifically around 7,000 steps per day, can significantly reduce mortality risk and the onset of age-related diseases [1]. Strength training and interval training are also encouraged as part of a balanced exercise routine [1].
Nutritional habits play an equally vital role. Experts recommend consuming between 0.8 to 1.2 grams of protein per kilogram of body weight daily; a 68-kilogram adult should aim for 54 to 81 grams [1]. Incorporating fermented foods into the diet supports a healthy gut microbiome, which is closely linked to healthy aging [1]. Sleep consistency, according to a 2024 study, matters more than sleep duration alone for predicting mortality rates, with experts recommending seven to eight hours nightly [1].
Preventive medical measures also feature prominently in the recommendations. The shingles vaccine can reduce dementia risk by approximately 20 percent [1], while staying informed about family medical history enables more targeted health monitoring and early intervention [1]. Vaccination schedules and routine immunizations round out the evidence-based approach to midlife health optimization [1].
