Heat and swelling

Swollen feet in hot weather: what may help

By Healthy Legs Daily Editorial Team | Updated August 5, 2026

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

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.
