One of the finest inventions among biking accessories are biking hydration bladders. Why? Because they help solve a big problem that’s been plaguing bikers for decades:

How do you pack enough water to keep yourself hydrated during a ride without using precious space and affecting your biking performance?

Water bladders are soft-sided plastic containers. They’re made from flexible and “squishy” plastic and are designed to hold significant amounts of water without leaking. They fit almost anywhere outside the main compartments of your backpack — giving you ample space for your other biking essentials.

Biking hydration bladders allow you to drink while riding. Thanks to its long drinking tube, you don’t have to stop in the middle of a ride to dig into your backpack.

Hydration is Essential

Biking is a very demanding physical activity. And keeping yourself hydrated is key to a fun biking experience. Remember that your body is made up of 70% water. Fluid losses can affect your biking performance significantly! For example, losing just 2% of your body weight due to sweating can affect your ability to focus. Lose 5% and you’ll start experiencing the symptoms of heat exhaustion. Heat stroke usually sets in if you lose more than 10% of your body’s water.

Keeping yourself well-hydrated helps your joints and muscles perform better. Water helps remove cellular wastes and facilitates better absorption of nutrients. Furthermore, it keeps your joints lubricated. Dehydration affects the volume of your blood. Lower blood volume means that your hearts need to work extra hard to deliver enough oxygen to your cells. This makes it more difficult to bike.
