“冬天出门不戴帽子，就像暖水壶没有盖子”？|帽子|帽檐|棒球帽|水壶|牛仔帽|针织帽|鸭舌帽

降温了，你平常出门会戴帽子吗？

戴帽子这个小习惯，不仅保暖而且防病。

有研究表明，静止状态下不戴帽子，气温15℃时，人体约1/3的热量会从头部散发；而气温在4℃左右时，约一半的热量从头部跑掉。

医生介绍，冬天戴帽子，犹如给身体加上一个“暖瓶塞”，减少热量散发，让身体更好地保暖，还有助于预防多种疾病！

As winter sets in, reaching for a hat does more than keep you warm — it can protect your health.

Research shows that at 15 C, about one-third of the body's heat escapes through the head when at rest. At 4 C, nearly half is lost. Doctors compare a winter hat to a "thermos lid", helping retain body heat and lowering the risk of several illnesses.

戴帽子能预防3种疾病

① 心血管疾病

冷风吹头，头皮上的血管会剧烈收缩，导致全身的血液循环受影响，心脏的压力加大。这时候心绞痛、心肌缺血甚至心梗的风险都会增加。尤其是老年人或者本身有高血压的人群，戴上帽子，可以减少冷空气对血管的刺激，让心脏“省点力”。

Cold wind causes scalp blood vessels to constrict, increasing strain on the heart and raising the risk of angina or heart attack — especially in older adults or those with high blood pressure. A hat reduces cold exposure, easing cardiovascular stress.

② 脑血管疾病

冷空气会让脑部供血不足，血压波动大时，容易诱发脑中风或者头痛。特别是那些本身有动脉硬化的人，脑部血管壁脆弱，一受刺激很可能引发脑溢血。戴帽子不仅能防止头部散热，还能保护脑血管少受寒冷刺激，减少风险。

Low temperatures can affect blood flow to the brain, increasing the risk of stroke or severe headaches, particularly in people with hardened arteries. A hat helps stabilize head temperature and protects delicate blood vessels.

③ 呼吸系统疾病

冬季室内外的温差比较大，一冷一热很容易导致免疫力低的人患上呼吸系统疾病。头部保暖对预防此类疾病很重要。

Moving between warm indoors and cold outdoors can weaken immunity. Keeping your head warm helps the body adapt and may lower the chance of catching a cold or flu.

戴帽子要注意这几点

① 长期不清洗帽子

帽子长期不清洗直接佩戴的话，可能里面会很油腻、滋生细菌，甚至引发毛囊炎，建议要定期进行清洗或更换帽子。

Wash hats regularly to prevent oil and bacteria buildup, which can irritate the scalp.

② 戴太紧或太沉

帽子太紧会压迫头皮，影响头部的血液循环，甚至引发脱发；而帽子太沉则会导致颈椎、头部等负担过重，不利于抬头、扭头等动作。

Avoid hats that are too tight or heavy, as they may limit circulation, strain the neck, or cause discomfort.
