Prithvi and Prana Mudra

Hi All Yoga Mudra experts

I wonder if someone could advice me. I am doing Prithvi Mudra for few days mainly for my hair loss etc. I want to start Prana Mudra for my eyesight (my eyes has -5 each).

My question is can i do both Mudras 45 mins each in same day or will there be any side effects if i do both.

Your advice would be appreciated.
