Causes of Insomnia
Or Why Won’t My Brain Shut Up?
Insomnia is reaching epidemic proportions in today’s society. For many of us, daily work has become less physical and mental demands have grown. And yet, our bodies are still driven by physical impulses.
This means that you are likely feeling higher levels of stress than the generations before you, yet you have no way of physically releasing and reducing this stress. Although stress is only one of the several causes of anxiety, it is without a doubt the most significant cause.
Exactly what is insomnia? At its most basic level, insomnia is an inability to fall asleep and stay asleep. Practically everyone has dealt with insomnia before. In many cases, it is only a temporary condition that goes away by itself. But some people suffer from chronic insomnia.
This means that they have been unable to sleep well at least three nights every week for a month or more. About 10 percent of the population has chronic insomnia. They are almost certain to also be suffering the effects of sleep deprivation.
Sometimes it’s really hard to identify what is causing insomnia. Temporary or occasional insomnia is often related to something that you may be doing, like drinking beverages with caffeine or taking medication with side effects. The causes of chronic insomnia are usually more difficult to diagnose. But you can almost certainly count on finding anxiety, stress and depression somewhere in the neighborhood.
Stress, depression and anxiety are often linked to insomnia because our brains are chemically driven. These conditions are related to an imbalance of different neurotransmitters in the brain. The reason that our ability to sleep gets mixed up in all of this is that falling asleep is chemically activated as well. In essence, our brain makes the shift from being awake and active to falling asleep by flipping a chemical switch.
Have you ever been awake at night wishing you could go to sleep, but your mind is going a thousand miles an hour? That’s because for some reason your brain isn’t making the switch. Most often, it’s because you’re still dealing with the stress of the day, or battling anxiety about tomorrow. Depression can also affect the process by making you sleepy at all the wrong times and then keeping you awake when you need to sleep. In short, the chemical transmitters in your brain are completely out of whack. It’s going to take some intentional behavior on your part to put things back in order.
