Dr. Vázquez, nutrition expert: “Swimming in the ocean makes your body burn far more energy than you think”
The health expert shared a video on TikTok warning about a mistake many people make when they go into the ocean.
When it comes to health, small habits can make a difference over time. One nutrition expert says many people make the same mistake every time they head to the beach: they don’t stay in the water long enough.
Nutritionist and health educator Jesús Vázquez recently shared advice on social media encouraging people to spend more time in the ocean.
“Don’t get out of the water after five minutes,” he says. “Stay in for at least half an hour. During that time, your body is working much harder than you think.”
“The colder the water, the better”
Vázquez says there are several reasons why spending time in the ocean can be beneficial.
First, he explains, water removes heat from the body much faster than air. To maintain its normal internal temperature of 98.6°F (37°C), the body has to use energy.
He also points out that even if you feel as though you’re standing still in the water, your muscles are constantly working.
“The waves and the resistance of the water when you walk force your legs, core and back to keep working to maintain your balance,” he says.
Another potential benefit, according to Vázquez, is for people who experience swollen legs or fluid retention.
“Being in the water acts like a natural compression stocking. The pressure of the water helps improve blood flow back toward the heart and promotes lymphatic drainage, especially if you’re walking in the water.”
Does swimming in the ocean help you lose weight?
Vázquez says it’s important not to overstate the effect.
“Does this mean swimming in the ocean makes you lose weight? No,” he says. “But it does mean those 30 minutes make your body work harder and increase your energy expenditure more than most people realize.”
He adds that colder water generally increases the body’s energy demands even further.
While cold water does increase the amount of energy the body uses to maintain its temperature, the effect varies depending on the water temperature, how long a person stays immersed, and individual factors such as body size and body fat. For most people, spending time in the ocean should be viewed as a healthy activity rather than a weight-loss strategy.
