As these exercises are known to increase the heart rate, which boosts your metabolism and makes it easy to burn fat.

4. Helps in regulating the blood sugar level

Cardio does not only help your heart but also helps in lowering the blood sugar i.e., glucose levels which in turn improve insulin resistance. This insulin resistance is crucial for patients suffering from diabetes.

5. Promotes better sleep

According to studies, people who perform cardio on a daily basis have shown better sleep patterns than people who don’t. Physical activity helps the simulation of quality sleep and helps in maintaining the sleep cycle.

These antibodies fight against multiple types of infections and strengthen our immune system. Some studies also show that the continuous flow of antibodies in our bloodstream can possibly reduce the chances of diseases like cancer and lung issues.

7. Helps in boosting mood
