Insomnia is a terrible sleep disorder involving problems falling asleep at night combined with issues staying asleep all the way through the night. It is caused by a variety of things, including the over-consumption of nicotine and caffeine; an unhealthy diet and a lack of exercise; mental illness such as depression or anxiety; and certain medical conditions like chronic pain.
While the word âpainâ inevitably conjures negative connotations, it is actually a crucially adaptive function. It serves two primary functions. The first is to alert us to the fact that we have incurred an adverse physical illness or injury. In this sense, it acts as a biological alarm bell signalling to us to either rest up and recover from illness or seek treatment and healing for injury.
It is perfectly normal, and even healthy, to feel anxious from time to time. Anxiety is actually one of our most basic psychobiological drives that functions to alert us to physical or psychological threats and danger so that we might take action to reduce and evade it.
