3. When you get a brain freeze, press and hold your tongue up to the roof of your mouth.
如果出现冰激凌头痛,将舌头顶在上颚。
你有没有过这样的经历,炎炎夏日里一口冰凉的食物下肚,头部会感到瞬间刺痛。
这种因食用冰冷食物而造成的急促性头痛在英语中被称为brain freeze或ice-cream headache,俗称冰激凌头痛,学名为翼腭神经节疼痛(sphenopalatine ganglioneuralgia)。
为什么会出现这种症状呢?是冰激凌太凉,冻坏了脑子吗?其实这和冷冻食物对口腔的刺激有关:
The roof of your mouth gets cold, which causes immediate constriction of the blood vessels. As soon as those blood vessels constrict, your body reacts by trying to dilate them very quickly in order to get more warm blood to the area and heat it up. Pain receptors in the roof of your mouth send a message up to your brain telling you you've got something bad going on in the roof of your mouth. And it causes you to experience an intense headache in your forehead.
口腔上部变冷,导致血管迅速收缩。当血管收缩时,身体就会立即做出反应,试图快速扩张这些收缩的血管,从而让更多温暖的血液流过,升高温度。而上颚的痛感神经就会告诉大脑,你的上颚有些不对劲儿。因此,前额就会感受到剧烈的疼痛。
一旦出现冰激凌头痛,可以喝一杯热饮,或者用舌头来温暖上颚,疼痛就会得到缓解。
