Human body has a natural mechanism for clearing your nose.Push your tongue against the top of your mouth and place a finger between your eyebrows and apply pressure. Hold it for about 20 seconds and your sinuses will begin to drain. or perform the below routine 3 times:

Perform 10 pressures on a cavity at the corner of the nostrils (point 1). You should almost close and open the nostrils when you do the round movement.

Perform 10 pressures on a cavity just below the corner of the eyes near the nose (point 2)

Perform 10 pressures on a cavity just below the ear, behind the earlobe (point 3)

Massage the earlobe 10 times (point 4)

After performing the above 3 times, you should feel immediate relief of your nasal congestion.

The pressures should be round movement. Do it with a very mild pressure. Just place your fingertips on the points and rotate with a little pressure. You should not push the cartilage of the nose and definitely not the ear’s. In the nose, only the bottom part of the nostrils are being pushed. In the ears (point 3), it’s the cavity just below the cartilage and the rotation is not wide, so you’re actually more pushing and releasing the point when you do the round movements.

Point 2 is just below the corner of the eyes where the tears come out (where you take the stuff out of your eyes when you wake up in the morning). The rotation is done without lifting the finger but by moving the skin. Again, it’s more of a pushing-releasing kind of rotation and you should feel the corner of the eye when you apply the pressure.
