Heat and swelling
Swollen feet in hot weather: what may help
Heat can make feet and ankles feel puffy for some people, especially after standing or sitting for a long time. Cooling down, changing position and gentle movement may be reasonable comfort measures, but heat should not be assumed to explain new or severe swelling.
Simple steps
- Take breaks from long periods of standing or sitting.
- Walk gently and move the ankles if it feels comfortable.
- Stay cool and follow your normal hydration guidance.
- Remove tight footwear or socks.
When heat is not a sufficient explanation
Contact a healthcare professional if swelling is persistent, worsening, painful, red, warm or limited to one side. Seek urgent help for chest pain or shortness of breath.
