The summer of 2026, according to AEMET, was the hottest in Spain since records began: it accumulated 61 days under a heatwave, whereas the previous record was 41 days in 2022.
To help the body dissipate excess heat, blood vessels widen. This process, known as vasodilation, facilitates heat loss through the skin.
In the legs, high temperatures can contribute to a greater feeling of heaviness and hinder venous return, especially if we spend many hours sitting or standing.
As a result, some people may notice more heaviness, tiredness, or swelling in their legs, especially at the end of the day. These discomforts tend to become more evident during the summer months and can improve by walking, resting, or elevating the legs.
Among the most common symptoms are a feeling of heavy or tired legs, slight swelling in the ankles and feet, tightness, tingling, a sensation of heat in the legs, or more visible marks from socks and footwear at the end of the day. In people with varicose veins or venous circulation problems, these discomforts can also intensify with high temperatures.
Staying active, avoiding staying in the same posture for many hours, hydrating properly, and elevating the legs for a few minutes can help relieve the feeling of heaviness.
When should you consult a healthcare professional?
Leg swelling is not always related solely to heat. It is advisable to seek a medical evaluation if it appears suddenly, affects only one leg in particular, is accompanied by intense pain, redness, or localized heat, or if symptoms such as shortness of breath or chest pain appear.
Mr. Loris adds mediven to its catalog
A few weeks ago, we added the Mediven range of medical compression stockings to Mr. Loris, designed to improve venous return and relieve frequent discomforts such as the feeling of heaviness, tiredness, or swelling in the legs.
Mediven offers different models, formats, and compression levels, so it is important to choose both the size and the degree of compression carefully. For people with diagnosed circulatory problems, the choice must be made following the indications of a healthcare professional.
Among the models now available at Mr. Loris is Mediven Cotton CCL1, a medical compression stocking made with organic cotton and designed to offer greater breathability. Its fabric has a thermoregulatory effect, a feature that is especially interesting during the hot months.
