Sleep deprivation kills your ability to get things done faster and accurate.  Studies conducted showed that employee yawning in their desk cannot stay alert, make good decisions manage a friendly mood at the office and cannot focus on tasks.  Better and quality sleep will definitely change all this.  If you are suffering from insomnia, try doing some exercise.  You already know that exercise provides lots of good health benefits and a good night's sleep is one of them.  Another tip is to choose what you eat during the day because foods are more conducive to a better night's sleep than others.  Avoid caffeinated beverages as much as possible.  Practice the 20-minute power nap and discover its benefits.  Stop using alarm clock that rips you out of your bed, instead use a gentler one but not gentle enough for you to ignore.  Another thing is, never bring your problems to bed.  Take a good sleep and tackle your problems afterwards.  Exposure to light while you are supposed to be sleeping can disrupt your body's internal cycles so it is better to keep your room as dark as possible.  You will find it much harder to go back to sleep if you wake up and see any kind of bright light.  The mattress where you sleep contributes a lot to you sleep quality.  Turn the mattress over every few months and replace it after eight years of regular use.  Search the market for a mattress that will give you what you wanted, like the memory foam mattress set.
