Question

Do you feel excess pressure while swimming under water? Why?

Answer 1

Yes. While swimming under water, we feel excess pressure because water exerts pressure on our body. 

The pressure in a liquid increases with depth:

P = ρhg

where ρ is the density of water, g is the acceleration due to gravity, and h is the depth.

Therefore, as we go deeper under water, the pressure increases, so we feel greater pressure on our body, especially on the ears.
