许多司机在开车疲劳时,都想吸支烟以解乏和提神。其实,这样对身体危害更大。因为当人体消耗体能时,肾上腺就会分泌大量的肾上腺素到血液中,使血液循环加速,心跳加快。此时,烟中的有害物质,如尼古丁、焦油、亚硝胺等,很容易趁机进入血液,从而造成机体中毒,产生恶心、胸闷、头昏、出汗、视力模糊、反应迟钝等现象。当然,交通事故也容易在此时发生。
Many drivers want to smoke cigarettes to relieve fatigue and refreshment when driving fatigue. In fact, this is more harmful to the body. Because when the body consumes physical energy, the adrenal glands secrete large amounts of adrenaline into the bloodstream, accelerating blood circulation and accelerating heartbeat. At this point, the harmful substances in the smoke, such as nicotine, tar, nitrosamines, etc., are easy to take the opportunity to enter the bloodstream, resulting in body poisoning, nausea, chest tightness, dizziness, sweating, blurred vision, unresponsiveness and so on. Of course, traffic accidents can easily happen at this time.
