The amount of water loss during physical activity can vary depending on several factors, including the intensity and duration of the activity, the ambient temperature and humidity, and the individual's level of fitness. In general, the more intense the activity and the higher the ambient temperature, the more water will be lost through sweating.

During moderate-intensity activities, such as brisk walking or cycling, a person may lose about 0.5-1 liter of water per hour. This can increase to 1-2 liters per hour during vigorous-intensity activities, such as running or playing sports and even more in hot and humid conditions.

It's important to note that sweating is not the only way that water is lost during physical activity, as water is also lost through breathing and urine excretion.

It is essential to stay hydrated during physical activities by drinking fluids before, during, and after exercise to replace the fluids lost through sweating and other means, as dehydration can lead to decreased performance and increase the risk of injury or heat-related illnesses.

It is generally recommended to drink about 17-20 ounces of fluid 2-3 hours before starting an activity and then drink 7-10 ounces every 10-20 minutes during the activity. after exercise, it is recommended to drink enough fluids to return to your normal body weight.
