Severe sleep deprivation, also known as insomnia, is definitely not a pleasant thing to deal with.
Sleep is crucial for the body & mind to function normally and at optimum levels. This means if you starting getting less sleep, or even no sleep at all, your body will start to suffer greatly for it. The trick is to find out what is causing your insomnia and stop it for good.
What is the most common cause of insomnia, you ask? Simply put, overactive brainwave activity. Most sleep deprived people think the causes of insomnia have to do with stress, poor eating habits, bad sleeping environment, depression, drug withdrawal, alcohol abuse, over the counter sleep aid dependency, as well as lots & lots of other things. Although these many different things can contribute to you developing insomnia and lack of sleep problems (indirectly), they are rarely the primary cause of insomnia problems.
It is your brains electrical pulses which are the true problem.
These electrical pulses — commonly called brainwaves — are being far too erratic when you’re trying to get to sleep. This abnormal brainwave behavior IS THE REASON you are unable to fall into a deep, sound sleep. In truth, those many things listed above can indeed help to cause this problem.
Now that you know the true cause of insomnia and sleep deprivation, doesn’t the idea of taking a warm bath with bath salts or even drinking herbal tea sound a bit silly? It isn’t a lie to say those things may help calm you and even relax you a bit more — but if your brainwaves are still behaving erratically, then deep sleep will remain now & forever out of your grasp. but you’re focus needs to be on fixing the MAIN cause of insomnia first!
