自慰对你有益吗?

Is Masturbation Good For You?

调查显示
Surveys show that
95%的男性以及大约72%的女性
95% of men and around 72% of women
在人生中有过手淫的经历
have masturbated in their life.
不过 传闻说手淫是不健康的
But, with rumours that it’s unhealthy,
它可能会导致失明 甚至会造成不育
can cause blindness, and even infertility,
手淫对你有益处吗?
Can masturbation be good for you?
让自己感到舒适可不仅仅是单身狗会做的事
Feeling yourself isn’t just for single people.
一份最近的调查显示 70%的非单身男性和
70% of men and 40% of women in relationships
40%的非单身女性也在四周内有过手淫的行为
reported masturbating within the 4 weeks leading up to a recent survey.
毕竟 手淫能让人感觉很棒
After all, it feels good.
它不仅会释放出控制大脑奖励及快乐中枢的多巴胺
Not only is dopamine released, which helps control the brain’s reward and pleasure centres,
减轻压力感
reducing the feeling of stress
在性高潮时释放的内啡肽还能减轻你的疼痛感
but other endorphins released during orgasm can decrease your perception of pain.
女性自慰可以减少月经痉挛
For women polishing the pearl can reduce menstrual cramping.
当然 在与睡眠相关的催乳激素的影响下
And of course with the help of the hormone prolactin, which is linked to sleep,
你可能会感到倦意并且睡的更多
you’re likely to feel exhausted and catch some much needed Z’s.
就像你得了一场感冒
Feel like you’re coming down with a cold?
一个研究发现 在手淫过程中 男性的免疫系统中的部分会被激活
One study founds that males components of the immune system activated during masturbation,
增加了血流中的白细胞数量
increasing the number of white blood cells in the bloodstream.
自慰也能帮助人降低患癌症的几率
Solo sessions might also help men reduce cancer,
频繁的射精可以降低患前列腺癌的风险
with high ejaculation frequency correlating with a decreased risk of total prostate cancer.
尽管不知道这是为什么
Though it’s unclear why,
研究者假定更多的射精意味着
researchers hypothesize that increased ejaculation means
前列腺中的潜在致癌物会被更规律的排放出去
potential carcinogenic secretions in the prostate are excreted more regularly,
减少这些致癌物在身体中的负面影响
decreasing their negative impact on the body.
但为什么人类和动物进化出了手淫这一举动呢
But why have humans and animals evolved to masturbate
毕竟手淫看起来只是白白浪费人的精力和精液
if it’s seemingly a waste of energy or semen in men?
事实证明自慰行为可以提高精子的质量
Well, it turns out that self-love can actually improve the quality of sperm.
最近有研究表明
A study showed that recent,
男性手淫会使下次做爱时有受精能力的精子数减少
male masturbation reduced the number of sperm inseminated at the next copulation,
但不会使留存在女性体内的有受精能力的精子数量减少
but not the number retained by the female.
由此可知 手淫是一个可使男性提高自身精子适应性的策略
From this, it was concluded that masturbation is a male strategy to improve the fitness of their sperm,
因为更年轻更有活力的精子更有可能使卵细胞受精
as younger sperm have a higher likelihood of insemination.
不仅如此 手淫也可以增强你的性功能
Not only that but masturbation can improve your sexual performance.
男性和女性都有从耻骨延展到尾骨的盆底肌肉
Both women and men have pelvic floor muscles that stretch from your pubic bone to your tailbone.
随着年龄增长 这些肌肉逐渐衰弱
As we age, these muscles weaken,
导致女性的性功能障碍和男性的勃起功能障碍
causing sexual dysfunction in women and erectile dysfunction in men.
但是抚摸阴茎或阴蒂可以刺激球海绵体肌的反应
But stroking the penis or clitoris can activate the bulbocavernosis reflex,
使得盆底肌肉收缩
resulting in pelvic floor muscles contracting.
这实际也能锻炼你的性肌肉
It’s essentially a workout for your sex muscles.
随着年龄增长 一氧化氮的浓度也会下降 导致性冲动减少
Nitric oxide levels also diminish with age and can contribute to a decreased sex drive
手淫可以帮助你在一生中维持血液中的一氧化氮浓度
but masturbation can help maintain it in your blood throughout your life.
不过 虽然手淫有诸多好处
But while masturbating does have physiological benefits,
运用丰富的自慰技巧也很重要哦
it’s important to mix up your technique.
如果每次都用同样的方法自慰 你可能对其他类型的刺激没什么性反应
Using the same way to get off every time can make you sexually unresponsive to other types of stimulation.
这可能会导致性冲动减少
This could lead to decreased sexual arousal,
或者和现实中的炮友做爱时性功能衰退
or performance when it comes time to do the deed with a real life partner–
所以请确保你在自慰时用了各种各样的技巧
so make sure you mix it up!
随着一天结束 手淫实在是一个又安全又健康的活动
At the end of the day, masturbation is a safe and healthy activity,
放点音乐 点几根蜡烛 自己度过一个美妙的夜晚
so put on some music, light those candles, and have yourself a good night.
