As mentioned before, exercise is a great way to improve your body and brain. But keep in mind as you exercise - it is summer! That means it is most likely going to be hot, humid, and pretty uncomfortable outside.
The American Heart Association states that the risks of dehydration, heat exhaustion and heat stroke increase when the humidity is above 70% and the temperature is above 70°F. This is well below the current Baltimore weather! When exercising in the heat, your body is working to cool you down through sweating while also attempting to deliver blood to your heart. Too much sweating results in fluid loss which then makes your heart work even harder. In fact, excessive fluid lost can result in damage to your heart and brain.
If you choose to exercise outdoors, be sure to hydrate frequently during your activity. Wear light, loose-fitting clothing and stop exercising if you begin to feel light-headed, dizzy, or nauseous. Check for heat advisories or warnings to see if it may be best for you to keep your exercise indoors. Try exercise tapes, free weights, cardio equipment, or take it to the pool. Many gyms even offer discounted student summer memberships so you can get your physical activity in the comfort of air conditioning. While it's important to stay active in the summer, it's also important to stay cool!
