For example, if you have a fear of heights, and you decide to go on a hike to overcome the fear. You might end up vomiting when you see that you are at a great height. This vomiting can also lead to loss of fluids which causes dehydration.

3. Excessive Sweating

Athletes or gym enthusiasts who spend hours in the gym, building their muscles also sweat a lot. The heat that the body generates from an intense workout session can make you feel dizzy and dehydrated. To avoid this situation, try to take a few sips of water in between the workout routine.

Hot climates also make people sweat excessively and cause dehydration. The problem with harsh weather is that your body will take a lot of time to adjust to it. So residents of extreme climatic conditions often suffer from dehydration.
