Walking is easily the most fun way to get some activity into your day and it acts as a stress reliever after a long day of work.
Besides its health-boosting benefits such as protection against diseases and increased energy, walking can also be beneficial for people with asthma as it is a low-impact activity and doesn't speed up your heart rate.
Walking, or hiking are both great activities for asthmatics, and they can be enjoyed at any pace they prefer. Moreover, walking doesn't increase you breathing rate so there is a smaller likelihood of developing asthma symptoms.
However, it's important to be mindful that cold air can constrict your airway, making it harder to breathe, which can make your asthma worse. Therefore, try to walk when the weather is warmer, and always carry an inhaler with you just in case.
