What is it
Warm compresses applied to the perineum during pushing, and a provider's choice of 'hands-on' (gentle pressure on the baby's head to slow crowning) or 'hands-off' (watchful readiness without touching) technique.
How your body works here
Perineal tissue stretches better when it's warm and well-perfused — warm compresses raise local blood flow and elasticity, so the tissue gives instead of tearing. Slowing the head's exit ('ease the crown') lets the tissue thin gradually rather than being stretched suddenly, which is the main mechanism behind severe (3rd/4th degree) tears. Different provider techniques all aim at the same goal: a slow, controlled crown.
Benefits (B)
- Warm compresses during pushing reduce severe (3rd/4th degree) tears meaningfully.Review sources ↓
- Hands-on and hands-off techniques both work when applied by an experienced provider — the key is a slow, controlled crown.Review sources ↓
- Simple, low-cost, comfortable for most people.Review sources ↓
Risks (R)
- None significant when done gently.Review sources ↓
- 'Hands-on' can feel intrusive during crowning — a conversation about preferences helps.Review sources ↓
Alternatives (A)
- No specific perineal support (associated with somewhat higher rates of severe tears in trials).Review sources ↓
- Perineal massage during pregnancy in the last month may modestly reduce tearing for first-time parents.Review sources ↓
Evidence summary
Cochrane review of perineal techniques (>20 trials) shows warm compresses reduce 3rd/4th degree tears. ACOG Practice Bulletin 165 endorses warm compresses; both hands-on and hands-off techniques are supported by evidence when performed by experienced providers.

Questions to ask your provider
- Do you use warm compresses during pushing?
- Do you prefer hands-on or hands-off during crowning?
- How will you help me push slowly through the crown?
