熬夜之后补觉，到底能不能"补"得回来？心脏在超负荷运转时，又会发出哪些"求救信号"？ 心脏发出的四大"求救信号" 刘健提醒，长期熬夜后若出现以下症状，需高度警惕： 1.异常胸闷、胸痛 "再刷五分钟手机就睡""赶完这份报告就睡"……深夜的你是否也常常这样告诉自己？我们都知道熬夜伤 身，但你是否真正了解，它对我们心脏的影响有多大？ 北京大学人民医院心血管内科主任、主任医师刘健在接受中新健康采访时表示，长期睡眠不足，会更容 易患上高血压、冠心病、脑卒中等心脑血管疾病。相比起睡眠7-8小时的人群，睡眠不足6小时的人群， 患高血压病风险增加3成，患冠心病的风险增加近5成，患脑卒中的风险增加7成。 尤其在活动或劳累后症状加重，休息后可缓解，需警惕心肌缺血的可能。 2.夜间呼吸困难 睡眠中突然憋醒、气促，需要坐起才能缓解，可能是心功能不全的表现。 3.莫名乏力伴心慌 经常出现不明原因的疲劳、头晕，并伴有心率过快或过慢等异常情况。 4.下肢浮肿不退 双腿或脚踝水肿，按压后凹陷恢复缓慢，可能与心脏泵血功能下降有关。 刘健补充道，长期睡眠不足会从生理和行为两个层面影响心脏健康：不仅会导致血糖、血压异常，激活 交感神经，引发炎症反 ...

Core Viewpoint - Long-term sleep deprivation significantly increases the risk of cardiovascular diseases, including hypertension, coronary heart disease, and stroke, with specific risk increases of 30%, 50%, and 70% respectively for those sleeping less than 6 hours compared to those sleeping 7-8 hours [1]. Group 1: Impact of Sleep Deprivation - Long-term sleep deprivation leads to a higher likelihood of developing hypertension, coronary heart disease, and stroke [1]. - Individuals sleeping less than 6 hours face a 30% increased risk of hypertension, nearly 50% for coronary heart disease, and a 70% increase for stroke compared to those who sleep 7-8 hours [1]. Group 2: Warning Signs from the Heart - Four major warning signs from the heart include: 1. Abnormal chest tightness or pain, especially after activity [2]. 2. Nighttime breathing difficulties, which may indicate heart failure [3]. 3. Unexplained fatigue accompanied by heart rate irregularities [4]. 4. Persistent lower limb swelling, indicating potential heart pump function decline [5]. Group 3: Recovery from Sleep Deprivation - Supplementing sleep after staying up late does not fully mitigate the damage caused by sleep deprivation [6]. - The body's biological rhythms are disrupted by late-night activities, affecting hormone secretion and metabolic regulation [6]. - Short naps can alleviate temporary fatigue but cannot reverse long-term cardiovascular and immune system damage caused by chronic sleep deprivation [6]. Group 4: Recommendations for Recovery - To recover from sleep deprivation, it is advised to maintain a regular sleep schedule, limit naps to 30 minutes, and engage in light physical activities [8]. - A balanced diet rich in protein, fiber, vitamins, and minerals is recommended, while avoiding high-fat and fried foods [8]. - Healthy snacks during late-night hours can help mitigate negative effects, with fruits and vegetables being preferable [9]. Group 5: Maintaining Heart Health - Adults should aim for 7-8 hours of sleep per night to protect heart health [10]. - Creating a conducive sleep environment and avoiding stimulants before bedtime are essential for improving sleep quality [11]. - Regular cardiovascular check-ups are recommended for individuals with sleep issues to monitor heart health [11].
