Isabel Viña, physician: "Heat produces vasodilation that predisposes fluid to accumulate in the tissues."

Isabel Viña , a doctor, explains why many people experience a feeling of bloating in their bodies during the warmer months.

This phenomenon is more common during the summer, and although it can be uncomfortable, there are steps we can take to reduce its effects.

The impact of heat on the body

During the summer, the heat causes vasodilation , which encourages fluid in the blood vessels to move toward the extracellular spaces, accumulating in the tissues. This accumulation is the main cause of the swelling that many people experience when temperatures are high. "The heat produces vasodilation, which predisposes fluid to leave the blood vessels and accumulate in the tissues," explains Dr. Viña.

Furthermore, the sweat generated by excess heat contributes to dehydration, which triggers compensatory mechanisms in the body. "One of these mechanisms is the release of a hormone called aldosterone , which retains salt and, therefore, also fluids," the expert points out.

Foods and habits that influence fluid retention

Eating habits during the summer tend to be more lax, which can worsen the feeling of bloating. Eating snacks and ultra-processed foods , which are high in salt, has a direct effect on fluid retention . Salt can retain up to three times its weight in water, which increases the feeling of bloating.

The doctor's advice for mitigating these effects is to maintain an active lifestyle, especially walking , which helps mobilize fluids in the body. Additionally, certain foods can be very helpful in relieving fluid retention, such as vegetables with diuretic properties, including asparagus , and refreshing fruits like watermelon and pineapple .

The power of potassium to reduce bloating

Eating foods rich in potassium also plays a crucial role in reducing fluid retention. Potassium helps neutralize excess salt in the body, promoting the elimination of retained fluid. Among the foods richest in potassium are bananas , sweet potatoes , potatoes , and spinach .

By incorporating these simple eating and physical activity habits , you can reduce the feeling of bloating during hot summer days and enjoy a lighter, healthier season.
