The cold temperature causes the blood vessel to narrow First of all, everyone’s blood pressure is higher in winter because low temperatures cause the skin to contract to control body temperature, putting pressure […]

疫苗+口罩的最佳保護效果

疫苗的作用機轉 無論那一個廠牌的疫苗(AZ、BNT、莫德納、輝瑞),注入人體後,會藉由免疫反應觸發B細胞以及T細胞*產生對病毒的抵抗力,B細胞產生抗體阻擋病毒,而T細胞則有能力攻擊受感染的細胞。 疫苗就像武器,給予人體對抗病毒時戰鬥的能力。 當病毒進入人體後,人體的免疫系統依然需要與病毒「作戰」,而獲得疫苗這項武器後,對抗病毒勝利的機率就會大大的提高! 外科口罩的作用機轉 外科口罩構造通常分成三層:外層防波濺、中層具過濾作用,內層可吸濕氣,並對於6μm以上微粒有阻隔效果。 功能為避免吸入病人咳出的飛沫微粒及附著的微粒上面的病毒。 很明顯的,疫苗並不能阻擋病毒進入人體!一旦病毒進入人體後,人體的免疫系統依然需要與病毒「作戰」。當吸入的病毒量大時對身體的免疫力也是一種負擔。 透過口罩建立體外防護罩,將含有病毒的飛沫微粒阻擋在人體外,減少病毒進入的身體機會,再加上疫苗建立起來的免疫力 -雙重的保護才是保護自己與家人最好的辦法。 因此疫苗和口罩不相衝突,打完疫苗加上口罩,持續獲得雙倍的保護力! 參考資料: 新冠疫苗:「一針還是兩針」等重要問題背後的科學 抗癌免疫軍團:T細胞、B細胞、DC細胞、NK細胞 一次報你知! – Heho健康 *T細胞:是淋巴細胞的一種,主要有細胞毒性T細胞(cytotoxic T cell)、輔助T細胞(helper T cell)和調節/抑制T細胞(regulatory/suppressor T cell)、記憶T細胞 (memory T cell)4種。 *B細胞:B細胞沒有攻擊感染細胞的能力,只能產生抗體。當B細胞被刺激會產生漿細胞(plasma cell)和記憶B細胞,漿細胞是人體製造抗體的工廠,可以產生抗體標記外來物入侵者的蛋白質,協助細胞毒性T細胞辨識入侵者。而記憶B細胞可以記憶入侵的抗原,若再次受到相同的抗原,就會迅速產生新的漿細胞和新的記憶細胞,漿細胞再次產生抗體消滅抗原。

打完兩劑疫苗,還需要戴口罩嗎?

美國洛杉磯、以色列恢復室內配戴口罩的規定 美國洛杉磯縣公共衛生部門宣布,隨著確診人數和住院人數的增加,過去一周平均單日新確診案例達到1077例,將從周六晚上恢復室內配戴口罩的規定。不論是否施打過疫苗,所有人都必須在室內配戴口罩。 不僅是洛杉磯,疫苗施打速度領先全球的以色列,在 Delta 變種病毒出現後也恢復在室內配戴口罩的規定。在 Delta 變種病毒出現以前,以色列專家預估疫苗施打率打 75% 以上可達成群體免疫,但 Delta 病毒出現後,已將此門檻上修至 80%。 以色列總理更在記者會上呼籲民眾:勤戴口罩、打疫苗,在公共場所與他人保持距離, 做好這三件事情,不必透過封城也可以抵抗 Delta 變種病毒。 病毒會因為想要存活而不停改變 綜合各國建議,在目前病毒疫情還沒有受到完全控制的狀況下,戴上口罩保護自己與家人,還是一個比較安全的做法。 MOCACARE 與您齊心抗疫 💪 MOCACARE 提供各等級的台灣製高品質口罩,點我購買享優惠! 參考資料: With Cases Rising, Los Angeles Will Reinstate Indoor Mask Mandate Saturday Living with COVID-19: Israel changes strategy as Delta variant hits Over 750 new COVID cases reported for 3rd day; deaths, […]

高血壓的標準以及原因?三個症狀以及六大控制原則

高血壓並不可怕,事實上,處於第一期高血壓的民眾,有機會可以透過改變生活以及飲食習慣良好控制血壓。掌握以下六個控制高血壓的黃金原則(SABCDE),搭配定期監測血壓的機器以及應用程式,以及定期回診,免於長期吃藥,並遠離高血壓伴隨而來的併發症…

何謂低鈉飲食?六個低鈉飲食的原則

研究發現鈉含量攝取過多是高血壓潛在的元兇之一,而高血壓可能會導致中風、心臟病、視力下降、腎臟受損以及阿茲海默症,是「隱形的殺手」。以成人而言,美國心臟病學會建議一天的鈉攝取量不應超過 2,300 mg,理想的攝取量約為1,500 mg。在台灣,依據衛生福利部建議,每日鈉總攝取量不宜超過2400毫克(約為6公克鹽)。

高血壓建議飲食: 得舒飲食(DASH Diet)

得舒飲食(DASH Diet) 英文字面上的意思是遠離高血壓的飲食(Dietary Approaches to Stop Hypertension)。1992年,美國國家衛生院研究何種飲食最能夠降低高血壓,多個研究結果發現得舒飲食有效降低高血壓。在不改變生活型態的情況下,實行得舒飲食的受試者的收縮壓下降了 6-11mmHg。除此之外,受試者的低密度膽固醇(LDL)也有下降。
