 So the time is now 19:00, I'm sitting in my lounge with my loved ones watching a show about a couple who had made millions in a matter of a few years from hard saving and a good income. My first thought, "right how can I make more money?" How can I provide a good future for my family, ah yes my blog.
 With halloween just around the corner, we are at that time of the year where many of us get a thrill of being scared senseless. Some may love the boost of adrenaline that comes from watching a horror film or being spooked just before they go to sleep. But what is fear and why are some of us attracted to it?

Also why it is sometimes that we can wake up feeling refreshed and other days just feeling so annoyed and drowsy? So before we start looking at the correct times to sleep we should take a look at some of the science behind sleeping. Feeling tired and not feeling sleepy is primary down to two different chemicals: Acetylcholine and adenosine. Acetylcholine is responsible for keeping us awake, whereas adenosine has the opposite effect making us feel sleepy. These two chemical are constantly in a 'battle' with each other; adenosine builds up when we are awake and when we sleep acetylcholine take its turn to overcome the adenosine which will eventually have us waking up. Other chemicals which are involved in making us feel sleepy and then making us wake up are cortisol (an awake hormone) and melatonin (sleepy hormones) |
