From Villain to Vital: What Lactic Acid Really Does (and Why Massage Helps Recovery)

Understanding Lactic Acid: Explore its vital role in recovery and the benefits of massage therapy in this insightful blog post by Point Clear Wellness.

Lactic Acid Isn’t the Villain You Think It Is

If your trainer ever told you to “flush out lactic acid” after a workout, here’s the truth—they were quoting a 1950s myth.

As a massage therapist, I’ve heard every theory about lactic acid: that it causes soreness, that it’s toxic, that you need to “push it out.” But when I started digging into the latest research, the science told a different story.

Lactic acid—more accurately, lactate—isn’t a villain at all. It’s a vital part of how your body recovers, adapts, and even grows stronger. Once again, the body reminds us that it’s wiser than our old textbooks give it credit for. At Point Clear Wellness, our massage therapy sessions often address that post-workout fatigue and soreness many people blame on lactic acid.

Why Lactic Acid Got Such a Bad Reputation

For decades, exercise science misunderstood what was happening inside your muscles. That burning sensation during a hard workout? Trainers blamed lactic acid buildup. Textbooks said it made you sore and tired.

But modern research flipped that script completely. Yes, lactate levels rise during effort—but your body recycles them quickly. In about an hour, lactate becomes energy again through a process called the Cori cycle.

The real culprit behind next-day soreness is microscopic muscle repair—tiny tears and inflammation from effort, not lactic acid.

👉 Translation: the burn isn’t punishment—it’s progress.

4 Myths About Lactic Acid—Busted

Myth #1: Lactic Acid Causes Soreness

Fact: Lactate clears within an hour. The ache you feel later (DOMS) is from muscle repair, not leftover acid.

✨ Reframe it: soreness = growth, not punishment.

Myth #2: Lactic Acid Is Waste

Fact: Lactate is fuel, not garbage. Your muscles, heart, and even brain use it for energy. It also signals your body to grow stronger by creating more mitochondria (your cells’ power plants).

✨ Reframe it: lactate is a messenger, not trash.

Myth #3: High Lactate = Poor Fitness

Fact: Feeling “the burn” means you’re working hard, not out of shape. Trained athletes don’t produce less lactate—they just use it better.

✨ Reframe it: lactate isn’t shame—it’s effort.

Myth #4: Massage “Flushes Out” Lactic Acid

Fact: By the time you’re on my table, lactate is already gone—but massage therapy still plays a crucial role in recovery by improving circulation, calming inflammation, and regulating your nervous system.

✨ Reframe it: recovery is about restoration, not chasing ghosts.

The Hidden Benefits of Lactate

Here’s what science now shows lactate actually does:

• Fuels your muscles, brain, and heart

• Helps build new blood vessels and mitochondria

• Supports muscle repair and reduces wasting

• Speeds up energy restoration after workouts

• Promotes memory and mood balance

• Signals the body to adapt and renew

✨ Reframe it: lactate is part of your body’s built-in wisdom—an ally in resilience.

When your body is processing these recovery signals, gentle Craniosacral Therapy can help quiet the nervous system and support deeper integration. Many of my clients pair CST with massage for a full-body reset that encourages balance and restoration.
