One of the most annoying flu symptoms is definitely the clogged nose. According to 'Prevention' there are several ways that can help you unblock your nose without using specific medications.
First Trump : Knocking the tongue.
Place the tip of the tongue near the teeth and then press firmly between the eyebrows. Repeat it around 20 seconds.
Second Trump: Keeping the breath
Turn your head back and keep as much breath as you can. When you start breathing freely, the sinuses will be cleansed.
Let's hope these methods work and make sleep in the evening.
