Feeling unwell after a massage is a recognized, though not universal, experience often termed Post-Massage Soreness and Malaise (PMSM). This condition involves temporary symptoms like fatigue, mild headache, and general malaise, sometimes feeling similar to the onset of a mild cold or flu. The physical manipulation of tissues prompts a physiological response that temporarily causes discomfort, even though massage promotes relaxation and healing. Recognizing these underlying body mechanisms helps view this reaction as a normal part of the therapeutic process.
Physiological Reasons for Feeling Unwell
The primary mechanisms behind post-massage malaise involve a significant shift in the body’s regulatory systems. Massage encourages the body to move from sympathetic nervous system dominance (“fight or flight”) to parasympathetic dominance (“rest and digest”). This shift slows heart rate and lowers blood pressure, which can cause temporary sluggishness or lightheadedness as the body adjusts.
Circulatory changes are another contributing factor. Mechanical pressure causes vasodilation, the widening of blood vessels, increasing blood flow to the treated muscles. The sudden increase in vascular space can cause a transient drop in overall blood pressure, known as orthostatic hypotension. This often results in dizziness or nausea, particularly when standing up quickly.
For deep tissue or intense structural work, soreness is often due to muscle micro-trauma. Manipulation of restricted muscle fibers creates microscopic tears, initiating a mild local inflammatory response. This inflammation is the body’s natural healing process, but it can lead to systemic fatigue and generalized achiness as the body works to repair the tissue.
Common Causes of Post-Massage Sickness
External factors and client conditions can amplify the body’s physiological reactions, making post-massage malaise more likely. Dehydration significantly heightens the risk of feeling ill because water is essential to manage circulatory changes and metabolic activity induced by the massage. When poorly hydrated, the temporary drop in blood pressure caused by vasodilation is more pronounced, increasing the likelihood of dizziness or a headache.
The type of massage received plays a large role. Deeper, more intense modalities like deep tissue or trigger point therapy are significantly more likely to induce PMSM than a light Swedish massage. These techniques cause greater muscle micro-trauma and a more robust inflammatory response. Additionally, a session performed on an empty stomach can lead to hypoglycemia, presenting with symptoms like dizziness, shakiness, and nausea.
Individuals with pre-existing conditions may also be more susceptible to post-massage symptoms. Those prone to low blood pressure or migraines may find these symptoms exacerbated by the circulatory changes. Intense stimulation can occasionally trigger a prolonged reaction in those with chronic fatigue syndrome or fibromyalgia.
Minimizing Symptoms Through Preparation and Care
Taking proactive steps before and after your session can significantly minimize the severity of post-massage symptoms. Pre-session preparation should include consuming a light, balanced meal within two hours of your appointment to maintain stable blood sugar levels. Consistent hydration is also advised in the hours leading up to the massage to support healthy circulation and metabolic function.
During the session, clear communication with your therapist about pressure tolerance is the most effective preventative measure against excessive soreness. If a technique feels uncomfortably intense, asking the therapist to reduce the pressure can prevent unwarranted tissue micro-trauma. After the massage, move slowly when getting off the table to allow your circulatory system to adjust to the change in posture, mitigating the risk of lightheadedness.
Post-session care should focus on continued hydration, resting, and avoiding strenuous activity for the remainder of the day. Drinking water helps flush out metabolic byproducts released from the muscles into the bloodstream. If muscle soreness develops, applying a warm compress or taking a warm Epsom salt bath can help soothe the muscles and aid the healing process.
Recognizing When Symptoms Are Serious
While mild malaise is a common, short-lived side effect, it is important to distinguish this from symptoms that require medical attention. Normal post-massage symptoms, such as fatigue, generalized soreness, or a mild headache, should begin to resolve within 24 to 48 hours. If symptoms persist beyond this 48-hour window or worsen, it may signal a more serious underlying issue.
Seek immediate medical attention if you experience severe, localized sharp or stabbing pain, especially if accompanied by numbness or tingling that lasts more than a few hours, which could indicate nerve irritation. Other serious warning signs include fever, severe vomiting, or signs of a deep vein thrombosis (DVT), such as sudden, intense swelling, redness, or warmth in a limb. These symptoms warrant prompt medical evaluation to rule out complications like vascular injury or rhabdomyolysis.
