Yes, frost can be harmful to fresh piercings. Exposing a fresh piercing to extreme cold temperatures can cause the skin to contract and potentially damage the healing tissue. It can also increase the risk of infection and slow down the healing process. It's important to keep fresh piercings protected from extreme temperatures and to follow proper aftercare instructions to ensure a healthy healing process. **

Fresh concrete is particularly vulnerable to frost because the water in the mix can freeze and expand, causing the concrete to crack and weaken. When fresh concrete is exposed to freezing temperatures, the water within the mix can turn into ice, leading to internal pressure and potential damage to the concrete's structure. To prevent this, it is important to protect fresh concrete from freezing temperatures by using insulating blankets, heating systems, or other methods to maintain a suitable temperature for curing. Additionally, using air-entrained concrete mix can help improve the concrete's resistance to frost damage by creating tiny air bubbles that can accommodate the expansion of freezing water. **
