NFL出于安全考虑,特别是可能掩盖脑震荡症状,已经禁止嗅盐。 The NFL has banned smelling salts due to safety concerns, particularly their potential to mask concussion symptoms. 含有氨的嗅盐被运动员用来提高警觉,但没有有力的证据表明它们能提高性能。 Smelling salts, which contain ammonia, have been used by athletes to boost alertness, but there is no strong evidence they enhance performance. 禁令是继澳大利亚国家橄榄球联盟和国际拳击联合会采取类似行动之后实施的,其目的是保护球员,以免头部受伤情况恶化。 The ban follows similar actions by the National Rugby League in Australia and the International Boxing Federation, aiming to protect players from worsening head injuries.
