Swimming and Swim Goggles: Things you need to Know

When it comes to swimming, there are a lot of benefits, from leisure to exercise and health. Swimming helps you burn calories, it boosts metabolism, gets you in shape, and strengthens every muscle in your body; all this it does without causing too much pain to your joints. This makes it one of the most advised routines to get involved in if you are looking for one. And if you are curious as to why swimming is so effective, here are a couple of reasons;

• Compared to running, swimming easily burns almost 500 calories per hour, and 700 calories for a rigorous one.
• Since water is at least 800 times denser than air, every action carried out under water or while swimming is an exercise on its own.
• When you swim, lean muscles are built, which results in increased metabolism and burning of calories.
• Your joints are able to rest when you are under water. This is because water almost neutralises gravity and your weight is automatically are relieved of all duties
• When you swim, the risk of sustaining injuries is minimised, and you look younger and healthier.

Whenever you decide to swim, it is always advised that you have the appropriate swimming gear, your swimming trunks and your swimming goggles. The swim goggles are very important as they act as a protective layer that keeps water, chemicals and impurities away from the eyes. Another important purpose of the swimming goggle is that it improves sight underwater. We have poor vision under water because the refractive index of air allows light travel at almost the original speed, but the refractive index in water slows light down by 75%. This is why our vision underwater is different from vision out of the water.

So for a seamless swim experience and to avoid eye irritations, it is advisable to always have swim goggles. But there are also a lot of things that are to be considered when buying swim goggles, some are;

• The fit of the swim goggles: We all have different face sizes, and these swim goggles are made for the different face sizes. So whenever you decide to start swimming, it's best you invest in one that fits your face perfectly. A lot of them come with adjustable bands and adjustable nose pieces. This is important, so water doesn’t start leaking into the glasses and affecting your sight while you swim. When this happens, it can result in great discomfort #
• The colour of the lens: when deciding on what swim goggle to buy, you should put into consideration the colour of the lens. This plays a major depending on the pool where you swim, an outdoor or indoor pool. Using a dark lens in an indoor pool when it's dark is really not good because you won’t be able to see anything.

Other things that are worth considering are things like the cost, for a beginner, you really don’t need a swim goggle that is expensive.
