When hiking, it is important to control your breathing in order to avoid overheating and exhaustion. There are a few different ways to do this:
1) Take regular breaks during your hike to breathe in fresh air. This will help you stay hydrated and energized.
2) Use a hiking hat or other cooling device when the weather is hot outside. This will help keep you cool and prevent overheating.
3) Practice deep breathing exercises before your hike in order to get used to controlling your breath while on foot. Doing this will help you conserve energy while hiking and avoid becoming exhausted quickly.
