Does Swimming Makes You Hungry? Heres Why!

swimming makes you hungry

What’s the deal with being ravenously hungry after swimming? I’ve been spending a lot of time in the pool, followed by a lot of time in front of the kitchen fridge. I fear I am undoing all the good of my pool workout.

While your post-swimming hunger maybe because you put in a good workout, there are two main reasons why hunger strikes upon leaving the water. One, your body’s changing temperatures as you move from land to pool, and two, dehydration.

The water you swim in is cooler than the air, and cool water is an excellent environment for working out, especially on sweltering hot summer days. Immersing your body in cool water lowers your body temperature, even when you are swimming hard. When you return to dry land (warmer temperature), your body wants to re-establish its ‘normal’ body temperature. What happens is that your body mistakes being cold for not enough fuel to keep it warm, which is when your hunger signal strikes.

Solution: Reheat without refueling. While your body needs carbohydrates to replenish its energy stores and some protein to repair the muscles, it needs post-swim to reset its temperature. A few good ways to do this are light stretching, going for a brisk walk, or taking a hot shower.

The thing is, you’re not hungry; you’re thirsty. Every cell in your body needs water. Your muscles are 75 percent water, your lungs are 90 percent water, your blood is 82 percent water, and even your bones are 25 percent water. When your body does not have enough water to perform all its tasks, it searches for insulin (sugar in the blood that can be used for energy). When you exercise in the water, you often forget to drink it! Did you know that being even five percent dehydrated leads to an energy loss of 25-30 percent? That’s enough to make you go running for the fridge.

Solution: The best way to stabilize your body temperature is to pre-hydrate. Drink 500 ml of water 20-30 minutes before you jump in the pool, drink 200-300 ml ( two to three gulps) of water for every 10-15 minutes you are in the pool, and follow up with 500 ml of water when you reach dry land.
