Nafasgirii shakhs dar vaqti khob nisbatan suratnoktar buda vobasta ba chiguna khobe, ki u mebinad teztar yo susgtar meshavad. Masalan, vaqge, ki shakhsro siyohy shmssh mekunad nafasgiry va harakatash tez va namoyon buda hatto ovozash ba berun mebaroyad. Sababhoi asosii «siyohi» pakhsh kardani odamon holati dokhili va berunii khudi bad.tni shakhs meboshand.
Masalan, agar shakhs pesh az khob gizoi vaznin khurda bar zammi on nodurust khob kunad, yo ki dar vaqti khobidan yagon uzvashro sakht qapida khob ravad uro «siyohi» pakhsh mekunad, yane m-n, vaqti khobidan bo yak dastash d digarashro qapida khobida boshad, pas khob mebinad, «siyohi»-jmn, dev va yo yagon jinsi qavijussa bo dastoni purpashmu baquvvati khud uro ba sui khud kashida istodaast u boshad khudro ba oqib qashida istodaast, «siyohi» ii khunhoi sakhshudai raghoi dastash buda harakathoi dasti u in amal ijroi farmon az tarafi maynai u baroi ba harakat ovardani khunhoi shakhshudai dasgash meboshand. SHakhsi siyohy pakhsh karda dar khobash sukhanoni poy dar havo gufta faryod mezanad. SHakhsoni kasalii mayozadagi niz nagz khob karda nametavonand va onhoro niz dar khobashon siyohi pakhsh mekunad.
Agar siyohi dar khob pakhsh namoyad chi boyad kard?
CHand sol pesh psikhiatr Ernest Hartmanro masalai baroi chi bazeho nisbati digaron beshtar khobhoi dakhshapiyuk mebinand norohat namuda bud. Va u dar tadqiqothoi laboratorii aniq namud, ki hamagi 5%-i odamonro har hafta takhminan yak bor khobhoi dahshatnok azob medihand.
Omuzishi nazdiki sad nafar khobi dahshatnokdidagon nshpon dod, ki khobhoi oddii in nafaron misli khobhoi dahshatnokashon ravshan va beshtar dar khotirashon meistad. Onho khotiroti davrai bachagiashonro hatto az se solagi nagz dar yod doshtand. Boyad qayd kard, ki Hartman asosan bo odamoni ejodkor-musiqidonho, rassomon va navisandagon kor dosht. Onho az kudaki olami atrofro hamchun ajoibotu mujizanok tassavur menamudand, beshtar vaqt az mavzui asosi dur meshudand va tobei tasavvurotashon meshudand va amiq fikr mekardand.
Hartman dar kitobi khud «Sarhadi shuur»(1992) ba khulosa meoyad, ki odamoni ba khobhoi dahshatnok mayl doshta doroi pardai boriki shuur meboshand, yane onho bisyor nozukdil va zudfahm(tezdark) nisbati digar odamon va olami atrof meboshand.
Pardai gafsi ego albatta baroi dar bayni odamon zindagi kardan muvofiq meboshad, vale vay baroi fikronii oddi va omuzishi suratnok muvofiq nameboshad. Pardai tunuki shuur boshad baraks. Sohiboni onho bisyor vaqt aftu basharai khdyvonot va yo ki odami jinsash muqobilro megirand, binobar in onho selai obrazhoi tavonoro paydo karda metavonand.
Dar haqiqat shakhsoni soqibi pardai tunuk bisyortar signalhoi zershuurro idrok mekunand, binobar in doroi khusiyathoi ziraki, farosatva hamdardi meboshand.
Hamon muhofizi avtomatii amalkunanda, ki moro az dard va oshuftagi muhofizat mekunad, ba tavri oddi selai az hama ravshani tasviru tasavurotro mekanand. Pardai dokhilii gafs, yane ego in sharti yakum va muhimi mavjudiyati nobigagii insoniyat meboshad.
