床上运动也是运动！性生活等于走路五公里
Sports in bed are also sports! Sexual life is equal to walking five kilometers
性生活最重要的，自然是「开心」!研究发现，性爱有利于健康，尤其是心脏的健康。
The most important thing in sex life is "happiness". Research has found that sex is good for health, especially heart health.
1、性生活是有氧运动
Sex life is aerobic exercise
人们戏称性生活为「床上运动」，它确实也是运动。研究发现，性生活属于中等强度的有氧运动。
People call sex life "bed exercise". It is also a sport. The study found that sexual life belongs to moderate aerobic exercise.
女性性爱过程中，每分钟大约消耗3大卡的热量。此外，跟所有有氧运动一样，过性生活能增强心脏、降低血压、减少患上2型糖尿病的风险。
Women spend about 3 calories per minute during sex. In addition, like all aerobic exercises, having sex can increase heart rate, lower blood pressure and reduce the risk of developing type 2 diabetes.
不过，任何人都不能只做床上运动。因为性生活在中等强度锻炼中属于运动强度偏低的种类，等同于20分钟走大约5公里距离。
But no one can do a bed exercise only. Because sex is a low intensity exercise in moderate intensity exercise, which is equivalent to 20 minutes walking distance of about 5 kilometers.
美国心脏协会推荐每周至少要进行150分钟的中等强度锻炼，因此如果要通过性爱来达成目标，每周必须「做」8次。
The American Heart Association recommends at least 150 minutes of moderate intensity exercise every week, so if you want to achieve a goal through sex, you have to do 8 times a week.
2、性生活能降低心脏病风险
Sex life can reduce the risk of heart disease
影视剧或者新闻中，人们偶尔可以看到有人在XXOO过程中心脏病发的剧情，但现实中，性爱引发心脏病的可能性微不足道.
In the movies or the news, people can occasionally see the story of a heart attack in the XXOO process, but in reality, the possibility of sex triggering a heart disease is negligible.
数据显示，只有不到1%的心脏病与性行为有关。相反，长远而言，健康的性生活会带来健康的心脏，降低心脏病发作的危险性。
Data show that less than 1% of heart disease is related to sexual behavior. On the contrary, in the long run, a healthy sex life can bring a healthy heart and reduce the risk of heart attack.
一项针对中年男性的16年长期研究发现，保持每周两次以上性生活频率的男性，比一个月一次的同性心脏病发的风险低得多。
A 16 - year study of middle-aged men found that men who had more than two times a week had a much lower risk of homosexual heart disease than once a month.
当然，也有可能是心脏好的人本来就倾向于更频繁过性生活，其中的因果关系有待科学进一步验证。
Of course, it may also be that people with good heart are inclined to live more frequently, and the causality between them should be further verified by science.
3、性生活能有效减压
sexual life can be effectively decompressed
性行为能促进快乐荷尔蒙「内啡肽」的分泌，这种物质有助于降低压力、改善情绪。
Sexual behavior promotes the secretion of happy endorphins, a substance that helps reduce stress and improve mood.
从逻辑上分析，一次理想的性生活能够带来满足感，改善身体体验，而任何能够放松人体、令人淡忘焦虑的事情，都对心血管健康有利。
Logically, an ideal sex life can bring satisfaction and improve the physical experience, and any thing that relaxes the body and forget the anxiety is beneficial to the cardiovascular health.
4、性生活改善睡眠
Sex life improves sleep
性行为促进快乐激素分泌，它们不仅有助于改善精神，而且能否放松身体，让人更容易入眠并且睡好。
Sexual behavior promotes the secretion of happy hormones. They not only help improve the spirit, but also relax the body, make people sleep more easily and sleep better.
澳大利亚一项研究表明，64%的受测者经历高潮后睡得更好，睡眠质量高，心脏健康也会受益。相反，糟糕的睡眠质量与高血压、过度肥胖和心脏病等疾病存在密切关联。
A study in Australia showed that 64% of the subjects slept better after the orgasm, and the quality of sleep was high, and heart health also benefited. On the contrary, bad sleep quality is closely related to diseases such as hypertension, obesity and heart disease.
5、性生活增进感情
sexual life improves feelings
感觉温暖和愉悦，作用比人们想象更大，尤其是，孤单是心脏病的一种已知的高危因素。因此，良好的社会支持对心脏健康有益。
Feeling warm and pleasant is more important than people think, especially loneliness is a known risk factor for heart disease. Therefore, good social support is beneficial to heart health.
那意味着与他人沟通良好对心脏可以带来积极的影响。
That means good communication with others can have a positive impact on the heart.
当然，这要求你的性行为需要是一种情感交流的结果，而不是纯粹的追求身体快感，否则15分钟的慢跑对心脏的好处更大！
Of course, it requires that your sexual behavior needs a result of emotional communication rather than pure pursuit of physical pleasure, or 15 minutes of jogging is more good for the heart!
