在新型冠狀病毒爆發(fā)期間，你可能仍然想通過(guò)散步或跑步來(lái)保持健康。你如何在運(yùn)動(dòng)時(shí)保持安全呢？

英國(guó)衛(wèi)生部給出了一些建議。人們應(yīng)該與他人保持1.8米的距離，以阻止攜帶病毒的唾液飛沫的傳播。保持這個(gè)距離，飛沫會(huì)在接觸到其他人之前落在地上。

但根據(jù)一項(xiàng)新的研究，還需要做更多的工作。如果你和其他人一起跑步，你們應(yīng)該并肩跑。這也降低了感染的風(fēng)險(xiǎn)。

比利時(shí)的研究人員模擬了兩個(gè)人一起行走或奔跑的情景。當(dāng)一個(gè)人在另一個(gè)人前面跑的時(shí)候咳嗽或打噴嚏，他或她的飛沫會(huì)擊中后面跑的人。但當(dāng)他們并排運(yùn)動(dòng)時(shí)，飛沫會(huì)落在后面，這樣他們不太可能被傳播上病毒。

教你改善免疫系統(tǒng)的幾個(gè)步驟：

增加你的維生素D水平。你可以通過(guò)曬太陽(yáng)和從一些食物中獲取維生素D，包括魚(yú)、雞蛋、奶酪和蘑菇。

睡眠充足。大多數(shù)人每晚需要7到9個(gè)小時(shí)睡眠。僅僅一個(gè)晚上的睡眠不足就可以使你的免疫細(xì)胞數(shù)量減少70%。

經(jīng)常鍛煉。這會(huì)使你的身體健康強(qiáng)壯。即使在家里，你也可以做俯臥撐和箭步蹲這樣的運(yùn)動(dòng)來(lái)保持健康。
