How Crying May Help Relieve Stress and Ease the Perception of Pain
Crying is a universal human response that can occur in moments of sadness, stress, fear, frustration and physical pain, but also during intense positive emotions such as joy or relief. Although tears are often viewed simply as an outward expression of emotion, their role may be more complex. Emotional crying can accompany psychological and physiological processes that, in some people, contribute to reducing emotional tension and changing the way stress or pain is experienced.
However, it would be too simplistic to say that crying is automatically a treatment for stress or pain. Research suggests that its effects depend on the circumstances, the individual, the reason for crying and, importantly, what happens afterward.
The different types of tears
Humans produce several types of tears. Basal tears continuously keep the surface of the eye moist and help protect it. Reflex tears are produced when the eyes are irritated by smoke, dust or certain substances. Emotional tears, meanwhile, are associated with intense emotional experiences.
The third type is particularly relevant to researchers studying the relationship between crying, emotions and stress.
Emotional crying is accompanied by changes in autonomic nervous system activity. Breathing, heart rate, facial expression and muscle tension may also change during an episode of crying.
A possible release of emotional tension
When people experience significant stress, the body enters a state of heightened activation. The sympathetic nervous system, which helps the body respond to demanding or threatening situations, can increase heart rate, alertness and muscle tension.
Crying can occur during this state of intense emotional activation. For some people, the episode is followed by a sense of relief or calm.
This does not necessarily mean that tears directly remove stress hormones from the body. The popular idea that crying literally “flushes out” stress hormones or toxins is not sufficiently supported by scientific evidence. Any benefit is more likely to involve the broader emotional response, physiological regulation and social support that may accompany crying.
The role of the nervous system
Following a period of intense activation, the body can gradually move toward a calmer state. The parasympathetic nervous system plays an important role in rest and recovery.
Some people therefore experience calmness, tiredness or relaxation after crying. This may reflect a gradual reduction in physiological arousal.
However, this response is not universal. For some individuals, crying may temporarily intensify emotional distress, particularly when it occurs in the context of trauma, severe anxiety or persistent rumination.
Crying and the perception of pain
The relationship between crying and pain is particularly interesting. Pain is not determined solely by the signals transmitted by nerves. The brain interprets those signals according to emotional state, attention, expectations and the surrounding context.
Stress and anxiety can intensify the perception of certain types of pain. Conversely, reducing emotional distress may sometimes alter the way pain is experienced.
Crying could therefore have an indirect effect on pain if it helps reduce emotional tension. This does not mean, however, that crying has a pain-relieving effect comparable to medication.
Endorphins and natural pain regulation
Endorphins are naturally produced substances that play a role in pain regulation and feelings of well-being. They are often mentioned when discussing the potentially soothing effects of crying.
However, the exact relationship between emotional crying and endorphin release remains unclear. Research on the physiological effects of crying is still limited, and there is not enough evidence to conclude that crying consistently triggers enough endorphin release to directly reduce pain.
The sense of relief experienced after crying is therefore likely to involve several interacting mechanisms rather than one single biological process.
The role of breathing
During crying, breathing often becomes irregular. Sobbing may alternate with deeper inhalations and prolonged exhalations.
After the crying episode, breathing may gradually return to a more regular rhythm. For some people, this transition may contribute to a feeling of relaxation.
This should not, however, be confused with a formal therapeutic breathing technique. The effects vary considerably between individuals and circumstances.
Why can people feel better after crying?
The relief that follows crying may also have an important psychological component. When an emotion is difficult to express in words, crying can provide a form of nonverbal emotional expression.
Crying may help a person acknowledge that they are going through something difficult and can sometimes communicate a need for support without requiring an explicit explanation.
The social environment can be particularly important. A person who cries in the presence of a supportive friend or family member may receive reassurance, comfort, physical affection or practical assistance. Some of the resulting relief may therefore come from this social response rather than from tears themselves.
The brain and emotional regulation
Emotions are not simply passive sensations. The brain constantly evaluates events, their significance and the appropriate response of the body.
Crying can accompany a period of emotional processing during which a person becomes more aware of what they are experiencing. For some people, this expression may facilitate a return toward a more stable emotional state.
But the outcome depends heavily on the circumstances. If crying is followed by persistent rumination, social isolation or continued exposure to the source of stress, the sense of relief may be limited.
This is why the idea that “crying always makes you feel better” is too simplistic.
Can crying really reduce stress?
Available evidence suggests that crying can be associated with reduced subjective distress in some circumstances, but the effect is neither automatic nor identical for everyone.
The environment in which a person cries appears to be particularly important. Research on emotional crying suggests that people may experience greater relief when their circumstances become more supportive after crying.
In other words, crying may form part of a broader process of emotional regulation rather than being the sole cause of relief.
Crying is not a sign of weakness
In many cultures, crying is sometimes associated with vulnerability or weakness. Yet crying is a normal biological and emotional response.
Adults and children may cry when they experience emotions that become particularly intense. The ability to express emotion does not necessarily mean that a person is unable to cope with a difficult situation.
Recognizing emotions and seeking support when necessary can, in fact, be part of healthy stress management.
When crying may require attention
Occasional crying in response to a difficult situation is generally a normal human reaction. However, very frequent, uncontrollable or distressing crying may indicate that a person is experiencing significant emotional difficulty.
When crying is accompanied by persistent sadness, loss of interest, major sleep problems, social withdrawal or difficulty functioning in everyday life, speaking with a healthcare professional may be appropriate.
The goal is not to prevent crying, but to understand what is causing it and determine whether additional support may be needed.
Crying can be much more than a visible expression of emotion. In some people, emotional crying may accompany a gradual reduction in physiological arousal, provide a way to express difficult feelings and facilitate the search for social support. These processes may indirectly contribute to lower perceived stress and, in certain circumstances, alter the perception of pain.
However, crying is not a medical treatment for pain or stress, and its effects vary from one person to another. The relief experienced after crying appears to depend on multiple factors, including the emotional context, the response of other people and what happens after the crying episode.
Crying when emotions become overwhelming can therefore be a normal human response. Tears should not automatically be viewed as a sign of weakness, while persistent or distressing crying deserves attention when it begins to interfere with everyday life.
