Saline is the same kind of water that is inside your body naturally.
When your cells come into contact with saline it creates an exchange – gunk comes out and fresh water goes in!
The Hot Water
Hot water makes the particles of salt move faster, making the solution more efficient at cleaning.
It also opens up skin pores and blood capillaries allowing more oxygen to the piercing. This speeds up the healing process.
Hot water prevents wound temperature from dropping. If it drops too low it can stop the healing process for up to 4 hours at a time.
Finally, hot water is also very soothing and helps swelling!
