Cool Down: The debate is over. Cooling down after a sweat session is mandatory. Stopping abruptly after vigorous activity can cause dizziness and fainting. In addition, your body needs time to adjust the hormone and acid levels that were built up during your vigorous activity. Cooling down allows the body to gradually return to a balanced state. Reduce the intensity of your exercise and continue at the level that will allow your heart rate to return to its pre-activity state. Once your heart rate is at a comfortable level, then complete your stretch routine. When in doubt, walk it out.
Replenish: Because we sweat it out, it is important that we replenish it. What is it? Electrolytes: Sodium, Chloride, Potassium, Magnesium, and Calcium. An electrolyte imbalance can lead to health issues. If you exercise for 1.5 hours or more during a single session, then be sure to replenish your electrolytes. An easy way to replenish them is to drink a sports drink because sports drinks often contain electrolytes and minerals. Another option is to make your own drink using one of the many recipes online.
