If your body has detected the presence of some kind of foreign invader like bacteria or a pathogen or perhaps even a virus, what it will do is that it will increase its core temperature to make it difficult for this pathogen to survive once all has been said and is now out of the way. The reason behind this is that higher temperatures are going to help cleanse your system, but it will also give you a fever which is going to make it a lot more difficult to go about your day than might have been the case otherwise.
You need to take some kind of medicine that can bring this fever down, and if you are sick at night the best thing to do would be to take Nyquil. This medicine is perfect for fevers since it will put you right to sleep and prevent you from having to deal with the unpleasantness that comes with suffering from a fever in the first place. If you read livealittlelonger.com you would realize that the medicine also works to break your fever while you are asleep, which means that when you wake up the next morning you are going to feel really refreshed almost to the point where you might feel like you had never even had a fever the previous night.
This medicine is popular for a reason, and you should think about using it if you have a cold or the flu. Fevers can be quite dangerous if they are not managed, since your body might go into overdrive and make the fever a lot higher than it actually needs to be which definitely won’t be something that you can get through with ease.
