Czech health guidance on pregnancy discomfort and swollen legs in summer heat

Medical experts advise pregnant women to dress in light, breathable fabrics such as cotton, silk or linen, stay well‑hydrated with cool water or unsweetened tea, and limit exposure to direct sunshine between 10 a.m. and 4 p.m. They recommend taking cool showers, using a damp cloth on the forehead, and avoiding excessive physical strain. Pregnant women should also monitor for dizziness, excessive sweating or breathing difficulties and seek care if symptoms worsen.

In hot weather, blood vessels expand and circulation slows, leading to fluid buildup in the lower limbs. Health professionals explain that high temperatures, prolonged sitting, tight footwear and salty meals increase the risk of swollen feet. They suggest elevating the legs, gentle massage or lymphatic drainage, short alternating warm‑cold showers, regular movement every 20–30 minutes, and wearing roomy, breathable shoes. Maintaining electrolyte balance with mineral water or foods rich in potassium and sodium, reducing salt and alcohol intake, and staying active are also recommended. Persistent, painful or inflamed swelling should be evaluated by a doctor as it may signal venous or lymphatic disease.
