Do your legs feel heavy or swollen, or do you notice an uncomfortable tingling sensation whenever temperatures rise? You’re not alone. With the arrival of hot weather and the holiday season, tired and stiff legs become one of the most common concerns among patients at our clinic.
Far from being just an aesthetic concern when wearing lighter summer clothing, heaviness and swelling in the lower limbs can be signs that our circulatory system is having to work harder due to the summer heat. That’s why, at Clínica Torrubia Garbayo, we explain why this happens during the summer and what everyday and professional solutions can help you restore comfort and lightness to your legs.
Why do our legs swell in hot weather?
To put it simply, the main reason is the direct effect of heat on the blood vessels. The human body needs to maintain a stable internal temperature and, to achieve this, blood vessels dilate to help release heat.
When blood vessels widen due to high temperatures, blood flow back towards the heart can become slower for two main reasons:
- Dilation of the blood vessels: When blood vessels dilate, the small valves responsible for helping blood flow upwards against gravity may become less efficient. As a result, blood can accumulate more easily in the lower legs.
- Fluid build-up (oedema): This can increase pressure around the ankles and calves. Consequently, some fluid may move into the surrounding tissues, causing swelling and fluid retention.
Everyday factors that can make the problem worse
In addition to the heat, certain summer habits can make circulation more difficult:
- Spending too long in the same position: Sitting or standing for many hours at a time, whether at work or during long journeys by car, train or plane, reduces the movement of the calf muscles, which naturally help pump blood upwards.
- Not drinking enough water: We sweat more in hot weather, so staying properly hydrated becomes particularly important. In addition, dehydration can contribute to feelings of fatigue and discomfort.
- A diet high in salt: Snacks, meals out and processed foods can increase sodium intake and, therefore, contribute to fluid retention.
- Hormonal factors: Women may be more prone to feelings of heaviness due to hormonal fluctuations associated with pregnancy, menopause or the menstrual cycle.

Practical tips to improve circulation at home
Relieving tired legs in summer requires consistency and small changes to your daily routine. Fortunately, there are several simple habits that can help reduce heaviness and discomfort.
1. Keep your legs moving
Gentle exercise is one of the best ways to encourage healthy circulation. What’s more, summer offers plenty of opportunities to stay active:
- Walk along the shoreline: The soft sand reduces impact, while the cool water and movement of the waves provide a natural massaging effect.
- Swim: The pressure of the water on your legs can support circulation and, at the same time, help reduce feelings of swelling.
- Move regularly at work: If you spend most of the day sitting, rotate your ankles, raise your heels while keeping your toes on the floor and, whenever possible, get up and stretch your legs at least once an hour.
2. Try a cool shower on your legs
Another simple option is to finish your daily shower by running cool water over your legs. Start at your feet and slowly move upwards towards your knees and thighs. In this way, the cool temperature can provide an immediate feeling of freshness and relief.
3. Use gravity when resting
As well as staying active, rest can also help. Spend around 15–20 minutes a day resting with your legs raised above heart level, supported on cushions or against a wall.
Likewise, slightly elevating your legs while resting can help relieve the feeling of heaviness after a long day.
4. Pay attention to hydration and diet
Hydration also plays an important role. For this reason, make sure you drink enough water throughout the day and include foods rich in antioxidants, such as berries and citrus fruits, as part of a balanced diet.
At the same time, it is advisable to moderate your salt intake, particularly during the summer months when eating out and snacking tend to become more frequent.
