當你由坐或瞓姿突然企起，血液未能即時供應足夠氧氣到腦部，形成姿勢性低血壓（orthostatic hypotension），導致短暫性視野模糊、頭暈甚至站立不穩。青少年、長者、飲水不足或患有自律神經功能障礙人士較常出現。

本文探討身體放鬆時對血壓與體溫的調節原理，並解釋點解浸熱水浴會令人昏昏欲睡，並非單純因為體溫升高。最後提供四項日常生活建議，幫助讀者利用體溫與血壓變化改善睡眠與壓力管理。

Vascular disease (vasculopathy) affects the blood vessels that carry oxygen and nutrients throughout the body and remove waste products from tissues. Common blood vessel problems occur when plaque (made up of fat and cholesterol) slows or blocks blood flow in an artery or vein. Lifestyle changes often help, but some people need medication or surgery.

Unbelievable, but your body has approximately 60,000 miles of blood vessels. Together with your heart and other muscles, they form your circulatory system. This road network transports blood to every corner of your body. But when your blood circulation is poor, it can slow down or block blood flow. This means that the cells in your body cannot get all the oxygen and nutrients they need.
