Blocked nose? Pressure Building? Heavy Head?
When your nose is blocked, pressure starts to build and build making your head feel heavy. It can make it hard to think straight; even the simplest things require more effort.
Nasal congestion is a blockage within the nasal passages which results in the pressure build-up that leads to the ‘Heavy Head’ effect. Congestion can be caused by sinusitis, colds, flu and allergies.
