After completing a workout, many people may be tempted to skip the cooldown and head straight to rest. However, health experts say that taking time for a proper cooldown is important for both immediate recovery and long-term physical performance.
Dr. Corbin Hedt, a physical therapist at Houston Methodist, explains the role of a cooldown after exercise. “Think of a cooldown as a transition period,” says Dr. Hedt. “It’s your body’s chance to taper down from high effort back to rest. The more intense your workout, the more important that transition becomes — but, really, a cooldown should follow any activity of moderate or greater intensity.”
He notes that group classes such as yoga or Pilates often include cooldowns in their structure due to instructor guidance. In contrast, individuals exercising alone or under time constraints are more likely to skip this step. “Class-based programs usually do a good job with warm-ups and cooldowns because they’re guided by someone who knows how to structure an effective session,” says Dr. Hedt. “It’s when we’re working out solo or pressed for time that cooldowns tend to get skipped.”
The body undergoes several physiological changes during exercise: heart rate increases, blood flow rises to muscles, and the nervous system becomes highly active. These processes do not immediately return to normal once exercise stops.
“There’s a period of time where your body is still operating at this elevated level while it figures out what your new normal looks like,” explains Dr. Hedt. “And if you stop abruptly, you’re not giving your body a chance to adjust.”
Without adequate cooldown, there can be continued high blood flow in extremities leading to swelling or discomfort due to blood pooling in the limbs. Cooldowns help maintain circulation as the body adapts post-exercise.
Dr. Hedt also highlights effects on the nervous system: “During intense exercise, your fight-or-flight response kicks in — that’s your sympathetic nervous system getting activated,” he explains. “A cooldown helps shift you back into a parasympathetic state, which is your body’s rest-and-digest mode.”
In addition to physical benefits, he notes mental recovery: “We get locked in during workouts,” he says. “Cooling down also gives you a chance to decompress and reflect on what you just accomplished — and feel good about it.”
Cooldowns serve different purposes depending on workout type. For cardio activities such as running or cycling, gradually lowering intensity helps bring heart rate back down and aids metabolic recovery.
“You’re running hard or for a long time and your heart rate is up,” says Dr. Hedt. “The cooldown helps you slowly bring it back to baseline.”
For strength training sessions, cooling down assists muscles and connective tissues as they recover from exertion by supporting blood flow.
“It’s more about keeping blood flowing to those muscles you just worked as they adjust to a more rested state,” Dr. Hedt explains. “This can potentially even reduce muscle soreness.”
He addresses common misconceptions about lactic acid removal through cool downs: “We’ve all heard that from coaches — that cooldowns help flush out lactic acid,” says Dr. Hedt.”But that’s a myth.The real benefit of cooldowns after strength training is supporting circulation and flexibility,and helping your nervous system shift from fight-or-flight back toa normal baseline.”
Accordingto Dr.Hedt,cooldowns need not be complexor lengthy.”If you’re doing cardio ,just reduceyour pace gradually ,”he suggests.”Go froma runtoa jogtoabrisk walktofinally an easy walking pace.You can even switch modes ,like goingfromrunningtogentle cyclingorswimming—and vice versa .”
After lifting weights ,light movementsoractive stretchesare recommended .”If you’ve been lifting heavy ,do light movements likebodyweight squatsorarm circles ,”he suggests.”Yoga poses likecat cowanddownward dogare great dynamic stretches .”
