Why Do I Feel Sick After a Deep Tissue Massage?

A deep tissue massage (DTM) is a therapeutic bodywork technique that uses sustained, firm pressure to target the inner layers of your muscles and connective tissue, known as fascia. Its primary purpose is to address chronic pain, muscle knots, and restrictions in movement that lie beneath the surface muscles. While the goal of this intense manipulation is to promote long-term healing, it is common for individuals to experience a temporary feeling of malaise or illness afterward, often referred to as “massage hangover.”

Common Post-Massage Reactions

The most frequent reaction is delayed onset muscle soreness (DOMS), which is a deep, aching tenderness in the areas that received the most intense pressure. This muscular discomfort is often similar to the feeling experienced after an intense workout. A wave of general fatigue and lethargy is also highly common, sometimes causing a sudden need to rest or even nap. Less frequently, individuals may experience a mild, dull headache or slight feelings of nausea. These symptoms usually peak within 24 hours, leading individuals to describe the experience as a mild, flu-like feeling that passes quickly.

The Physiological Causes of Discomfort

The feeling of sickness is rooted in a physiological process triggered by the intense pressure of the deep tissue work. One mechanism involves the release of metabolic byproducts that have been trapped within chronically tight muscle tissue. The mechanical pressure forces accumulated waste products, such as urea and compounds often mistaken for lactic acid, out of the muscle fibers and into the circulatory and lymphatic systems. This sudden influx requires the liver and kidneys to work harder to filter and process the waste for elimination.

Furthermore, the intense manipulation of muscle fibers initiates a localized inflammatory response, which is the body’s natural way of starting the repair process. The intentional creation of micro-traumas in the tissue promotes healing and the realignment of muscle fibers, but this process activates inflammatory mediators. This low-grade inflammation is what causes the familiar muscle soreness and can contribute to the overall feeling of being “run down.”

Deep tissue massage also strongly influences the nervous system by promoting a rapid shift from the sympathetic state, known as “fight-or-flight,” to the parasympathetic state, or “rest-and-digest.” This sudden transition to deep relaxation can cause a temporary drop in blood pressure and heart rate. For some, this shift results in a feeling of lightheadedness, dizziness, or profound tiredness as the body adjusts to the lowered state of arousal.

Strategies for Quick Recovery

Proper hydration is the most effective and direct strategy to aid recovery. Drinking plenty of water helps the kidneys and liver flush out the metabolic waste products that were released from the muscle tissue. It is helpful to continue sipping water throughout the remainder of the day to assist the detoxification pathways.

While intense exercise should be avoided, engaging in gentle movement, such as a short, slow walk, can help. Light activity encourages circulation and lymphatic flow, which aids in the swift removal of mobilized compounds and prevents pooling. Applying heat is another simple, effective way to soothe muscle soreness and promote healing. Taking a warm bath, perhaps with Epsom salts, can relax the muscles and provide relief from the tenderness.
