Does Crying Burn Calories? A Doctor-Reviewed Answer

Crying does use some energy because breathing, facial muscles, and the body’s stress response are active, but the amount is too small and variable to be a meaningful source of calorie burning. Occasional crying is a normal emotional response; persistent or unexplained tearfulness may deserve medical or mental health support.

Does crying burn calories?

Does crying burn calories? Technically, yes: crying requires some activity from the facial muscles, breathing muscles, and nervous system. However, the energy used is likely very small, varies greatly from person to person, and is not enough to meaningfully affect weight, body fat, or daily calorie balance.

There is no well-established medical calculation for calories burned by crying. Although intense sobbing can temporarily change breathing rate and heart rate, this is not comparable to sustained physical activity such as walking, cycling, or swimming. Crying should not be viewed as a weight-loss method, and there is no need to feel concerned about occasional crying affecting nutritional needs or metabolism.

For most people, crying is a healthy and common response to emotion, pain, relief, frustration, grief, or overwhelming stress. The more useful health question is usually not how many calories crying uses, but whether crying is occasional and understandable or frequent enough to affect sleep, relationships, work, school, appetite, or the ability to cope day to day.

What happens in the body during crying?

Crying involves the lacrimal glands, which produce tears, along with coordinated activity in the face, throat, chest, and diaphragm. Emotional crying may include changes in facial expression, vocalization, faster or irregular breathing, a tight feeling in the chest or throat, and a runny nose. These physical responses can make a person feel temporarily tired, especially after prolonged sobbing.

The autonomic nervous system also plays a role. This system helps regulate involuntary functions such as heart rate, breathing, sweating, and digestion. During acute distress, the body may shift into a heightened state of alertness. As the episode passes, some people notice a calmer or fatigued feeling as breathing slows and the body settles.

Tears are not all the same. Basal tears keep the eyes lubricated, reflex tears help clear irritants such as smoke or onion vapors, and emotional tears occur in response to feelings. All can lead to watery eyes, but only emotional crying is closely linked to changes in mood and stress. The precise energy cost of these processes has not been adequately measured in a way that supports a dependable calorie estimate.

Why crying is not a weight-loss strategy

Weight change develops over time from many factors, including food intake, physical activity, sleep, medical conditions, medications, stress, and genetics. A meaningful calorie deficit generally requires sustainable changes that support overall health. Brief emotional responses, including crying, do not create a predictable or useful calorie deficit.

It can also be unhelpful to connect distress with calorie burning. People who are grieving, anxious, depressed, or under significant pressure may have appetite and sleep changes, but these symptoms are not healthy or reliable ways to manage weight. Unintended weight loss, loss of appetite, or preoccupation with calories during emotional distress should be discussed with a healthcare professional.

A balanced approach to weight management focuses on regular nourishment, enjoyable movement, adequate sleep, and individualized medical advice when needed. A clinician or registered dietitian can help identify realistic goals, especially when weight changes occur alongside hormonal symptoms, digestive concerns, medication changes, or emotional difficulties.

Common reasons a person may cry more often

Many temporary situations can make crying more likely. These include grief, relationship difficulties, work or caregiving strain, conflict, exhaustion, financial pressure, illness, pain, and major life transitions. Crying may also happen after an emotional event has passed, when the person finally has time and safety to process what happened.

Sleep deprivation can lower emotional resilience and make ordinary frustrations feel harder to manage. Hormonal shifts, including those associated with the menstrual cycle, pregnancy, the postpartum period, perimenopause, or menopause, may also affect mood. Some medicines and substances can influence mood or sleep as well, so it is helpful to mention all prescription medicines, over-the-counter products, supplements, alcohol, and recreational substances during a medical review.

Frequent tearfulness can sometimes be associated with anxiety, depression, trauma-related symptoms, or other mental health conditions. In some cases, neurological conditions, thyroid disorders, chronic pain, or other medical illnesses may contribute to mood changes. Crying alone does not diagnose any condition, but patterns and accompanying symptoms can guide an appropriate evaluation.

• Consider the timing, triggers, and duration of crying episodes.
• Notice changes in sleep, appetite, energy, concentration, and interest in usual activities.
• Pay attention to physical symptoms such as palpitations, tremor, pain, fever, or unexpected weight change.
• Seek support early if emotions feel difficult to manage alone.

When to seek medical care

Occasional crying that has an understandable trigger and settles with time is usually not a medical emergency. It is reasonable to arrange a routine appointment with a doctor or mental health professional when crying is frequent, lasts for weeks, feels out of proportion to circumstances, occurs without a clear reason, or begins to interfere with everyday functioning.

Medical review is particularly important if tearfulness occurs with persistent low mood, intense worry, panic symptoms, irritability, hopelessness, social withdrawal, major sleep disruption, changes in appetite, or difficulty concentrating. A person should also speak with a clinician if crying began after starting or changing a medicine, following childbirth, during a significant hormonal transition, or alongside new neurological symptoms such as weakness, confusion, changes in speech, or severe headaches.

Urgent help is needed if a person has thoughts of self-harm or suicide, feels unable to stay safe, has thoughts of harming someone else, experiences severe agitation, or loses touch with reality. In these situations, they should contact local emergency services, go to the nearest emergency department, or reach out to an available crisis service. If possible, they should not remain alone and should tell a trusted person what is happening.

How a doctor evaluates frequent crying

A doctor will usually begin by listening carefully to the person’s experience. They may ask when the crying started, whether there are identifiable triggers, how long episodes last, and whether symptoms affect sleep, work, relationships, or self-care. Questions about recent losses, stress, trauma, pregnancy or postpartum changes, menstrual patterns, substance use, and current medicines can help identify contributing factors.

The clinician may ask about mood, anxiety, energy, appetite, concentration, and thoughts of self-harm. A physical examination may be appropriate when there are symptoms suggesting an underlying medical issue. Depending on the history, blood tests may be considered to check for contributors such as thyroid problems, anemia, infection, nutritional deficiencies, or other conditions; testing is individualized and is not necessary for every person.

Assessment is not about judging emotional expression. Its purpose is to understand whether crying is a normal response to a difficult situation, a sign of a treatable mental health concern, or part of another health condition. If needed, a doctor may recommend counseling, psychological therapy, lifestyle support, medication review, further medical tests, or referral to a relevant specialist.

Supportive steps for emotional well-being

When crying is connected to ordinary stress or a temporary difficult period, gentle self-care can be helpful. This may include maintaining regular meals, drinking enough fluids, getting consistent sleep where possible, spending time outdoors, and choosing manageable physical activity. Slow breathing, writing down feelings, or speaking with a trusted friend or family member may also help some people regain a sense of calm.

It is often useful to reduce the pressure to “stop” emotions immediately. Crying can be one way the body and mind respond to strain. Instead, a person can focus on what they need after crying: rest, comfort, connection, practical help, or time to reflect. If episodes are frequent, keeping a simple note of mood, sleep, events, and symptoms can provide useful information for a healthcare appointment.

Professional support can be valuable even when symptoms do not feel severe. Talking therapies can help people develop skills for grief, stress, anxiety, low mood, or major life changes. Acibadem International’s multidisciplinary specialists and JCI-accredited hospitals can assess physical and emotional contributors to persistent symptoms and coordinate appropriate care for international patients.

Frequently asked questions

How many calories does crying burn?

There is no reliable, clinically established number of calories burned by crying. The body uses some energy during any activity, including crying and sobbing, but the amount is expected to be small and varies with the intensity and duration of the episode. It is not enough to have a meaningful effect on weight.

Can crying make a person lose weight?

Crying itself does not cause meaningful fat loss or healthy weight loss. Emotional stress can sometimes change appetite, sleep, and eating habits, which may influence weight over time, but these changes should not be treated as a weight-management strategy. Unplanned weight changes should be discussed with a clinician.

Why does crying feel physically exhausting?

Intense crying can involve rapid or irregular breathing, muscle tension, sobbing, and activation of the stress response. Afterward, the body may shift into a more relaxed state, which can leave a person feeling tired. Dehydration, poor sleep, or prolonged emotional strain can add to that fatigue.

Is it normal to cry for no reason?

Sometimes a person may not immediately recognize the reason for crying, especially when stress, tiredness, grief, or hormonal changes have built up gradually. Occasional unexplained tearfulness can happen. If it becomes frequent, distressing, or is accompanied by low mood, anxiety, or changes in daily functioning, medical advice is appropriate.

Does crying help relieve stress?

Some people feel calmer or emotionally lighter after crying, while others do not. The response is individual and may depend on the situation, whether the person feels supported, and what happens afterward. Crying can be part of emotional processing, but persistent stress may also benefit from practical support or counseling.

When is frequent crying a sign of depression?

Frequent crying can occur with depression, but it is not enough on its own to diagnose depression. A clinician also considers persistent low mood or loss of interest, changes in sleep or appetite, low energy, guilt, poor concentration, and thoughts of death or self-harm. Anyone with suicidal thoughts or concerns about personal safety should seek urgent help.
