Question

How much pressure do we carry on our heads ? why donot we feel it ?

Answer 1

We carry 14.7 pound/squ. on our head.

Atmosphere is a mixture of gases and it pushes on us with atmospheric pressure. Thus, we don't feel the weight of atmosphere. 

Answer 2

Answer:

We carry atmospheric pressure of about 105 Pa on our heads. We don't feel it because this atmospheric pressure is balanced by the pressure created by the air and blood inside our body.
