Valentine's Day is not all aboutmushiness, flowers and chocolates, for now a new research has shown that Cupid's magic works as far as the health of your heart is concerned.

    Women in happy marriages are much less likely to have a heart attack than those in high-stress relationships, research at the University of Pittsburgh, in the US, found.

    And men who have sex two or more times a week halve their risk of a cardiac arrest, a study at Bristol University found.

    Hugs lower your blood pressure while making love is a great cardiacworkout.

    It temporarily raises blood pressure and gives the arteries and veins a workout, keeping them strong and flexible.

    Cathy Ross, a specialist nurse with the British Heart Foundation, says: "Sex can provide the same benefits as walking up severalflightsof stairs."

    And it's a lot more fun which means we're more likely to stick with the exercise regime.

    We burn on average 200 calories when we have sex. But trying out different positions can increase the burn and fun.

    HUGS also help. Doctors at the University of North Carolina, in America, found cuddles can lower blood pressure and boost levels of the relaxing feelgood hormone oxytocin.

    Kissing is also recommended for gums and teeth because it increases production of saliva, which helps kill the bacteria that cause tooth decay and gum disease.

    In the long term this can even help to head off a heart attack because gum disease can increase the risk of heart attacks.

    情人節(jié)帶給你的不僅僅是激動(dòng)、鮮花和巧克力，一項(xiàng)最新研究顯示，愛(ài)神丘比特還能讓你的心臟更加健康。

    美國(guó)匹茲堡大學(xué)的一項(xiàng)研究發(fā)現(xiàn)，擁有幸福婚姻的女性患心臟病的幾率遠(yuǎn)遠(yuǎn)低于那些婚姻狀況不佳的女性。

    布里斯托爾大學(xué)的一項(xiàng)研究表明，一周有兩次或兩次以上性生活的男性心臟驟停的風(fēng)險(xiǎn)要小一半。

    此外，擁抱可以降低血壓，而性生活則可以鍛煉心臟功能。

    擁抱和性生活會(huì)使血壓暫時(shí)升高，能讓動(dòng)脈和靜脈得到鍛煉，從而使它們保持強(qiáng)勁和柔韌。

    英國(guó)心臟基金會(huì)的護(hù)理專家凱西·洛斯說(shuō)：“性生活所能起到的作用和上幾段樓梯差不多。”

    而且，這種“鍛煉”更有趣，人們更容易堅(jiān)持。

    一次性生活能夠燃燒平均200卡路里的熱量，嘗試不同的姿勢(shì)則可以增加熱量的燃燒，還可以增加樂(lè)趣。
    
    擁抱對(duì)身體也有好處。美國(guó)北卡羅萊納大學(xué)的博士們發(fā)現(xiàn)，擁抱能夠降低血壓，還可以促進(jìn)能讓人感到放松和舒適的腦下垂體后葉荷爾蒙的分泌。

    接吻對(duì)牙齦和牙齒有好處。因?yàn)榻游强梢栽黾油僖旱姆置冢瑥亩�有助于殺死引起蛀齒和牙齦疾病的細(xì)菌。

    由于牙齦疾病會(huì)增加患心臟病的風(fēng)險(xiǎn)，所以從長(zhǎng)期來(lái)看，接吻甚至有助于降低心臟病的發(fā)病率。
