Not being able to get enough sleep is actually one of the biggest problems that people face in their day-to-day lives. It's a huge problem, which is estimated to regularly affect up to a third of the World's population, but is actually one which is pretty easy to fix.
Essentially, not being able to sleep is actually just down to one problem - not being relaxed enough to allow yourself to fall unconscious. When we fall asleep, our brains actually switch off and "recharge" for the night, rearranging all your memories and thoughts for the day. It's a natural thing that most animals do, and is essential for us humans because we think about so many things.
The problem is that in order to fall asleep, you first need to fall unconscious. This is where so many people fall down. Because we are naturally programmed to fall asleep when we are sure that everything is safe, we need to be extremely relaxed and calm before doing so. However, if you are someone who tends to worry about things, or is just generally anxious, you can actually be preventing yourself from being able to fall asleep because your brain is constantly working, trying to keep track of all the things you feel you need to.
Normally, to stop this and fall asleep, people will just pop a pill. I'm not going to lie - this will probably send you to sleep... but the problem is that sleeping pills can become incredibly addictive and have nasty side effects. There are more effective ways of falling asleep and one of the most powerful is to use a herbal insomnia cure. These cures are made up of plants (herbs) which contain chemicals and properties which allow your brain to relax and fall asleep. They work by giving your brain the ability to fall unconscious and stay unconscious naturally, allowing you to get a deep refreshing sleep!
