Ketamine and Exercise: Physical Activity During Treatment

The Short Answer

Yes — you can exercise during a course of ketamine therapy. In fact, regular physical activity likely improves outcomes. What matters is timing relative to your ketamine sessions, and being sensible about intensity on treatment days.

What to Do on Session Days

On the day of a ketamine session itself, err on the gentle side:

• Before the session (earlier in the day): Light movement is fine — walking, stretching, easy yoga. Avoid high-intensity training that leaves you dehydrated or with elevated resting heart rate.
• During the session: You'll be lying down, eyes closed, for 45–90 minutes. No movement at all.
• Immediately after: Rest. Your coordination, judgment, and blood pressure regulation are all temporarily altered. No driving, no lifting heavy things, no activities where a stumble matters.
• Later that evening: Gentle walking is usually fine. Save the gym for tomorrow.

The Day After

Most patients feel clear-headed within 12–24 hours. Normal exercise — including high-intensity training, weights, and cardio — is fine once you feel fully oriented. There's no residual pharmacological reason to avoid exercise the day after a session.

A few patients report mild fatigue for 24–48 hours after early sessions as their system adjusts. If that's you, listen to it. Scale back intensity, not frequency.

Why Exercise Helps Ketamine Therapy Work Better

There's good neuroscience behind combining ketamine with an active lifestyle:

• BDNF synergy. Ketamine increases brain-derived neurotrophic factor (BDNF), which supports synaptic plasticity and new neural connections. Exercise does the same thing. Stacking them gives you compounding benefit — your brain is in a state of heightened plasticity, and exercise helps reinforce the positive changes.
• Mood regulation. Exercise independently treats depression and anxiety. Patients who maintain regular activity during ketamine therapy typically report better between-session mood stability.
• Sleep improvement. Both ketamine and exercise normalize sleep architecture. Combining them tends to produce better, more consistent sleep than either alone.
• Cardiovascular conditioning. Ketamine transiently raises blood pressure and heart rate during sessions. A well-conditioned cardiovascular system tolerates this better. Regular aerobic exercise between sessions is effectively "training" for your session-day physiology.

What to Avoid

• Intense training immediately before a session. Don't go into a ketamine session dehydrated, depleted, or with elevated BP from a morning HIIT class.
• Fasting + intense exercise + ketamine. The standard session-day fast (4 hours before) combined with a hard workout can leave you hypoglycemic and lightheaded during treatment. Eat an appropriate meal earlier or skip the hard workout.
• New PRs on session day. Not the day to push your deadlift max.
• Exercise immediately after a session. Your equilibrium isn't fully back for several hours. Respect that.

Special Cases

Patients with hypertension: If you're being treated for blood pressure, keep your medications on-schedule and check your BP both before exercise and before your session. Bring any concerns to your physician. See our blood pressure and ketamine guide.

Patients with chronic pain: Gentle movement between sessions often improves outcomes more than rest. Ketamine's anti-inflammatory and anti-hyperalgesic effects can give you a window of better mobility — use it for rehabilitation exercises rather than pushing to the point of re-injury.

Patients with a history of eating disorders: If exercise has historically been a compulsive or compensatory behavior for you, discuss this with your physician before combining it with ketamine therapy. The increased neuroplasticity cuts both ways.

The Bigger Picture

Ketamine works best as part of an integrated treatment plan, not as a standalone intervention. Patients who combine ketamine with regular movement, sleep hygiene, nutrition, and ideally some form of talk therapy or structured integration practice get substantially better outcomes than patients who treat sessions as isolated events.

Exercise is one of the most accessible, evidence-based interventions you can add to your ketamine treatment — and it costs nothing.

Questions About Your Specific Situation?

Every patient is different. If you have questions about how to time exercise around your treatment, or whether certain activities are safe given your medical history, bring them up in your intake or any follow-up visit.
