Feeling Cold While Swimming: Why It Happens and What Helps
Why you or your child may feel cold in the pool, simple ways to stay warmer and the signs that mean it is time to get out.
Short answer
Feeling cold is a sign to warm up or stop, not something to push through. Shivering, blue lips or a child who is quiet and clingy mean it is time to get out.
Why swimmers feel cold
Water takes heat from the body faster than air does. Beginners often stand or move slowly, so they warm up less than active swimmers. Small children lose heat quickly. Wind after leaving the water adds to it. See pool temperature.
What can help
- Keep moving, or ask the coach to include more movement.
- Take a shower before entering if the venue allows it, and keep the water time short at first.
- Bring a towel or robe and dry clothes, and dry off and dress quickly after the lesson.
- Ask whether a swim cap or rash vest is allowed. We do not claim these prevent cold.
- Have a warm drink and a snack ready.
When to get out
- Strong or constant shivering.
- Blue or purple lips.
- Clumsy movement, confusion or unusual quietness.
An online guide cannot assess a swimmer
This is general guidance. If a child or adult is very cold, get them out, dry and warm. Seek medical help if they do not improve or seem unwell.
For babies and toddlers, see heated pools.
