Your immune system becomes weak due to Flu symptoms. In order to allow the immune system work effectively, you need to give your body substantial rest. It is advised that sleep at least 8 hours or more rest in order to get rid of the flu symptoms instantly.
Flu is often associated with dehydration, which can lead to discomfort and may prolong the symptoms. In order to stop the flu symptoms from prolonging, it is advised that you should increase the fluid intake. The increased fluid intake will soften the trapped mucus in the nose and chest and will allow it to flow more smoothly.
Decongestants should be used very rarely and only if you are having difficulty in breathing or nasal congestion, which creates problem in sleeping.
Note: Excessive use of Decongestants can result in blood pressure, constipation, and tremors.
Instead of going for allopathic or homeopathic medicines, it is good to rely on herbal medicines. Take some chicken and vegetable soups along with garlic and ginger tea.
Note: Remember that using herbal medicines in excess can also have negative effects.
Keep yourself active
Although it is advised to give your body maximum rest when up against flu, but it is also good to engage yourself in healthy activities in order to defeat flu symptoms. You can just have some walk around instead of running for miles.
