Exercising can help you feel better mentally and emotionally in several ways. For instance, exercise reduces stress, improves self-esteem, and relieves anxiety. Additionally, exercise is great for cognitive health benefits, such as increasing mental alertness and focus. In other words, exercising can help you stay sharper mentally and able to think more clearly. However, you don't have to join a gym or spend hours at the gym to get your workout in - there are plenty of other ways to get physical activity in. For example, hiking, biking, running, or swimming are all great options that can be enjoyed outdoors and offer many health benefits.
