• e-mail

It turns out, the old adage is true - laughter really is the best 薬／医学.

専門家s say it 作品 wonders for your mental and physical health, with an ever-拡大するing 団体／死体 of 研究 pointing to its 傷をいやす／和解させるing 力／強力にするs.

によれば doctors, laughter can 援助（する） in respiration, 持続する heart health?and manage 強調する／ストレス, の中で other 利益s.

Scientists still don't understand why we laugh, but they 一般に believe laughter is a byproduct of 進化 that 許すd our 原始の ancestors to build 信用 and socialize with one another with the help of the neurochemical oxytocin.?

Laughing is most 有益な in social settings and is 批判的な for building social 社債s, something humans need, によれば Dr Eileen Anderson, a psychologist who 熟考する／考慮するs laughter at 事例／患者 Western Reserve University.??

She told DailyMail.com: 'If we were selling laughter as a 麻薬 it would sell off the 棚上げにするs because it both makes you feel better, and it 静めるs you 負かす／撃墜する. And it's accessible to everybody across the lifecycle and from all different backgrounds. And it's 解放する／自由な.'?

によれば doctors, laughter can 援助（する） in respiration, 持続する heart health and manage 強調する／ストレス, の中で other 利益s?

When we laugh, we take a lot of 深い breaths, which 許すs the 団体／死体 to take in more oxygen than it would さもなければ, relaxing muscles.

The Canadian 肺 協会 says: ‘When you laugh, your 肺s are rid of stale 空気／公表する and more oxygen can enter. This is because laughter helps to 拡大する alveoli in your 肺s.

‘These are tiny 空気／公表する 解雇（する） ? of which there are about 300 to 500 million! 拡大するing these means that the area for oxygen 交流 is bigger and more oxygen enters your 肺s.’

That 上げる in oxygenation 改善するs respiratory 機能（する）／行事 by relaxing muscles in the 肺s and cardiac 機能（する）／行事 by 増加するing 循環／発行部数.

It is believed laughing has a 肯定的な 影響 on the inner lining of 血 大型船s, called the endothelium, by helping it 解放（する） nitric 酸化物. Nitric 酸化物 is known to relax the arteries that carry 血 away from the heart.

Relaxed arteries are いっそう少なく likely to experience spasms and are more likely to stay open, 許すing the smooth passage of oxygenated 血 to the 残り／休憩（する） of the 団体／死体.?

Dr Lindsay Wilson-Barlow, a 臨床の psychologist at the University of Utah, said: ‘熟考する／考慮するs have shown that 簡単に 20 seconds of laughter has the ability to 二塁打 heart 率 for the に引き続いて three to five minutes.?

'As a result, [laughter 支持する Norman Cousins] 述べるd laughter as “a form of jogging for the innards.”’

It’s no surprise that a hearty laugh at a comedic 業績／成果 or a friend's joke can 解除する the dark clouds over your 長，率いる during a time of mental 苦しめる, whether it's a bad 崩壊／分裂 or a 一区切り／（ボクシングなどの）試合 of 不景気.

The 力／強力にする of laughter goes neuron-深い. It 減少（する）s levels of the 強調する／ストレス hormone cortisol and alters the activity of dopamine, the 団体／死体's reward hormone, and serotonin, the feel-good hormone.?

These neurotransmitters are instrumental in 規制するing emotions and 動機づけ to chase goals and 実行する needs.?

Even 軍隊ing yourself to laugh can have 利益s, and it's known as laugh therapy by clinicians who use it with 患者s. The ability to find humor in the world and 許す yourself to laugh 現実に 強化するs over time, like a muscle, Dr Anderson told DailyMail.com.?

She said: 'So people who make some 肉親，親類d of 一致した 成果／努力 to try and laugh will start to attune to funny things, and find themselves 肉親，親類d of laughing more throughout their life.'?

Laughing lowers levels of the 強調する／ストレス hormone cortisol 同様に as adrenaline, modulating the 団体／死体's natural fight-or-flight 返答. It's also a 決定的な 構成要素 of building social 社債s thanks to oxytocin

Laughing also makes managing 強調する／ストレス easier. It 抑えるs cortisol, the hormone that fluctuates in 返答 to 強調する／ストレス, and adrenaline. These are instrumental in 扇動するing the 団体／死体’s fight-or-flight 返答.

Dr Wilson-Barlow said: ‘Laughter induction 始めるs the fight-or-flight 強調する／ストレス 返答. However, だいたい 20 minutes after laughter, physiological 対策 such as heart 率, 血 圧力, and muscular 緊張, 減少（する） below baseline levels.

‘A sense of physiological and psychological 緩和 and calmness occurs that can last up to 45 minutes に引き続いて the person’s last laugh.’

Laughing has been shown clinically to 減少（する） levels of cortisol and adrenaline in people’s 血. A 1989 熟考する／考慮する 実験（する）d the 力／強力にする of ‘mirthful laughter’ by dividing 10 men into two groups ? one in which the men watched an hour-long funny movie, and a 支配（する）／統制する group that did not.

The people who laughed saw a statistically 重要な 減少（する） in cortisol circula ting in their 血.

They also had 意味ありげに 減少（する）d levels of a 構内／化合物 that results from dopamine breaking 負かす／撃墜する, which 示唆するs that laughing 現実に slowed 負かす／撃墜する the metabolism and 決裂／故障 of dopamine, 許すing them to feel better.

While laughing can help us feel better emotionally, it also can help us feel better 肉体的に.

The 行為／法令／行動する of laughing leads to the 解放（する） of endorphins in the brain, which helps 支配（する）／統制する 苦痛.

A 1995 報告（する）／憶測 in the 定期刊行物 苦痛 divided people into four groups of 20 and had them watch different movies.?

One group watched a comedic film, another watched a ‘repulsive’ film, the third watched a ‘中立の’ film, and group four watched nothing at all.

Both the humor and repulsive groups showed 意味ありげに higher 苦痛 寛容 when they immersed their 手渡すs in ice-冷淡な water to 手段 how long they could withstand the 不快 compared to the 中立の film group and the no-film group.

研究 finds laughing can help to 緩和する symptoms of heart 病気?

Scientists in Brazil 行為／行うd a 裁判，公判 to 診察する whether 'laughter therapy' can 改善する cardiovascular symptoms. It looked at adults who had all been 診断するd with coronary artery 病気.?

The repulsive group 論証するd the largest 増加する in 苦痛 寛容, although the difference from the humor group was not statistically 重要な.

Lower cortisol and 強調する／ストレス brought on by laughter also relieve muscle 緊張.

A 1999 熟考する／考慮する in the Lancet 報告（する）／憶測d laughter can 誘発する／引き起こす muscles in the 団体／死体 to relax.?

研究員s from the Netherlands 大（公）使館員d electrodes to volunteers’ 脚s to 手段 H-reflex, a neurological pathway that 原因（となる）s muscles to 契約, and then showed them a 一連の slides meant to elicit some reaction.

Those people who laughed saw their muscle 緊張 dissipate.

The 研究員s 設立する said: ‘When the volunteers laughed out loud, their H-reflex 事実上 disappeared, 反して it 減少（する）d much いっそう少なく when they did not laugh.’

Laughter itself can 行為／法令／行動する as a sort of muscle. The ability to tap into it as a means of feeling better emotionally or 肉体的に can be 改善するd and 強化するd.?

But Americans do not laugh enough, Dr Anderson told this website. But that's why more 研究 is needed into why we laugh, what makes us laugh, and how we can best use that capacity for humor to our advantage.

SHE SAID: 'So many other cultures just had humor built in, and joy built in and 緩和 built in. But we are like the 24/7 運動ing culture where you think you're gonna 落ちる behind if you don't ride that wave.?

'I think that's why this 研究 seems 革命の. For us, it's it's in some ways countercultural, and that's why we can't just know this, we have to have something called laugh therapy, we have to prescr ibe it, we have to have programs for it.'
