How Long After Shocking Your Pool Can You Swim? [Fact Checked!]

Standing by the pool with your toes in the water, a gentle splash against your feet and the relaxing sound of running water nearby – it sounds like paradise to us!

But how long can you stay in this blissful state after shocking your pool? What are the after-effects of having a pool party and how long does it take to get back to normal?

Let’s dive into the science of swimming, shock therapy, and how long it takes to recover.

How Does Swimming Work?

Anyone who has ever plunged their body into a pool fully knows how wonderful being wet feels. But how exactly does swimming work?

It turns out that a lot of science goes into designing the perfect pool. If you’ve ever wondered how a pool stays afloat, it’s because there are a lot of little people (known as ‘copepods’) living in it. Let’s have a look.

There are four main components that make up a swimming pool:


The most important thing to consider about a pool is what’s in it. If you’ve ever wondered why some pools are clear while others are cloudy, look no further – it’s all about the content. The clarity of a pool determines how much light can penetrate it while the color of the water influences how it looks. Most pools now are designed with a saltwater-endocrine system, so they can mix the water, which in turn provides a more natural-looking appearance.

To give you an idea of how much science goes into a typical pool, one of our friends in the UK designed a pool with light-emitting diode (LED) strips that provide a soft indoor/outdoor light. The LEDs are arranged in a geometric pattern to create a soft uniform light that does not dazzle like a typical bulb would. This enhances the beauty of the pool by providing better contrast and an overall sense of tranquility.


Just like with most things in life, the more you have of something, the more you need. It follows that the more people you have in your pool, the more you need. Thus, the density of your pool determines how many people you can fit in it. As a general rule of thumb, the more dense the pool, the fewer people you can fit in it.


Fins are little appendages that are placed at the end of a fish’s tail, which allows the creature to swim faster and with more agility. We don’t have fins on our tail, so we’re less likely to benefit from their velvety touch when in the water. However, it’s not entirely bad – you can hold your breath longer when using your finswimmigheter (‘fingers’ for those who don’t speak Swedish).

There are three types of fins that you will find useful when in the water. First are the two dorsal fins, which are placed on the back for extra stability while swimming. The second are the pectoral fins, which are on the front of the fish and provide extra lift for those quick bursts of speed.

Surface Tension

Finally, we come to the surface tension, the last and most important of the four parts that make up a swimming pool. This is where all the magic happens. Think of a balloon – if you squeeze it, even the slightest bit, it will pop.

The surface tension of water is the amount of energy that is required to separate a droplet of water into its constituent parts. Put more simply, the surface tension is the property that makes water ripple, bounce, and even break away in violent bursts – if the surface tension is great enough, the water will literally jump out of the pool at you!

The surface tension of a swimming pool is usually between 0.3 and 0.5 newtons, which is lower than the density-regulated pool and higher than the volume-regulated one. What this means is that you will experience greater buoyancy changes and greater resistance when diving into a dense pool.

How Long Does It Take To Recuperate?

So you had a pool party and lost a few friends, but you’re back in your routine now. You’ve dived in and out of the pool a few times and everything seems fine. But then… you feel a sudden rush of symptoms – cramping, leg weakness, and perhaps even fainting. What is this?

From a scientific perspective, it’s not hard to put your finger on the root of these problems. If you’re used to a routine healthy lifestyle, it will take you some time to get back on track after being in the water. Especially since you’re bound to overuse your muscles in the process of getting out. This is why it’s important to give your body time to adjust and restore its equilibrium. Just like with any other muscle in your body, you need time to restore your muscles’ strength after using them.

According to research, it takes your body about 10 days to regain full strength after being in the water. During this time, you should restrict yourself to taking long, relaxing drags on your morning vape and slowly work your way back to peak performance. Of course, if this is your first time in years in the water, it will take you longer. But that’s a fact that you must accept. For the average person, it takes about 10 days for all the negative effects of being in the water to fade away.

Hopefully, this article will help you better understand what happens to your body after getting out of the water. From the moment you step in, your body is working to heal itself and get back to its natural state. At first, you’ll feel dizzy and weak due to changes in your blood volume. But after a while, you’ll find that your body adjusts and you can enjoy being in the water again. Just make sure that you’re careful not to overexert yourself and jeopardize your health in any way.
