Crying more than usual can stem from a wide range of causes, from hormonal shifts and sleep loss to depression, personality traits, or simply being under more stress than your body can absorb. Women cry an average of 5.3 times per month and men about 1.3 times, according to research spanning several decades. If you’re consistently above those numbers, or if crying feels uncontrollable, something specific is likely driving it.
What Emotional Tears Actually Do
Your body produces three types of tears, and only one is tied to emotions. Basal tears keep your eyes lubricated around the clock. Reflex tears flush out irritants like dust or onion fumes. Emotional tears are different: they’re triggered when your brain’s emotional center sends a signal through a relay station to your tear-producing glands.
Emotional tears have a unique chemical makeup. They contain higher levels of stress hormones, prolactin, and natural painkillers that aren’t found in your other tears. Some researchers believe this is why a good cry can feel like a release. Your body may literally be flushing stress chemicals out through your tears and resetting itself toward a calmer baseline. Emotional tears also appear to serve a social function, signaling to others that you need support.
Depression and Anxiety
Frequent crying is one of the hallmark symptoms of depression. People with major depressive disorder often experience tearfulness, sadness, or a sense of emptiness most of the day, nearly every day, during depressive episodes. The crying can feel disproportionate to whatever triggered it, or it can come with no clear trigger at all.
What makes depression-related crying distinct is the pattern. It tends to persist for weeks rather than days, and it usually shows up alongside other changes: disrupted sleep, low energy, difficulty concentrating, loss of interest in things you normally enjoy, or shifts in appetite. Teens may experience this as feeling “extremely sensitive” or misunderstood rather than classically sad. If your crying fits this pattern, it’s worth taking seriously as a signal rather than dismissing it as oversensitivity.
Anxiety can produce a similar effect. When your nervous system stays in a heightened state for long stretches, your emotional threshold drops. Things that wouldn’t normally make you cry, a frustrating email, a minor disagreement, a sentimental commercial, can suddenly push you over the edge.
Hormonal Shifts
Fluctuations in estrogen and progesterone directly affect mood regulation. When levels drop, as they do before menstruation, during the postpartum period, and throughout perimenopause, the result can be irritability, low mood, and heightened sensitivity to stress. This is why you might notice predictable crying spells in the days before your period or feel emotionally volatile during major hormonal transitions like pregnancy or menopause.
Postpartum mood changes deserve special attention. Mild “baby blues” in the first couple of weeks after giving birth are common and usually resolve on their own. But persistent sadness, guilt, or emotional disconnection that stretches beyond those early weeks can signal postpartum depression, which affects roughly 1 in 7 new mothers and responds well to treatment.
Chronic Stress and Burnout
When you’re under sustained stress, your body pumps out cortisol and other stress hormones continuously. Over time, this wears down your capacity to regulate emotions. Your fuse gets shorter. Situations you’d normally handle without much reaction start producing tears because your system is already running near its limit. The crying isn’t really about the thing that just happened. It’s about everything that’s been accumulating.
Burnout follows a similar path. Emotional exhaustion from work, caregiving, or relentless demands gradually erodes your ability to contain feelings. Crying becomes the pressure valve your body reaches for when it has nothing left. If you notice that your crying correlates with periods of intense pressure or sleep loss, stress is a likely culprit.
Sleep Deprivation
Poor sleep doesn’t just make you tired. It measurably impairs your ability to process emotions. Research on healthy adults found that sleep deprivation reduced their accuracy in reading facial expressions of happiness and sadness, the two emotions most central to social bonding and empathy. In practical terms, this means that when you’re sleep-deprived, you’re worse at interpreting social cues and more reactive to emotional situations. The good news: accuracy returned to baseline after recovery sleep, suggesting this effect is reversible once you start sleeping adequately again.
You Might Be a Highly Sensitive Person
At least 1 in 5 people (some researchers estimate closer to 1 in 3) have a trait called sensory processing sensitivity, commonly known as being a highly sensitive person. If this describes you, your brain processes emotions and environmental stimuli more deeply than average. This isn’t a disorder. It’s a personality trait linked to a gene that amplifies how strongly you experience emotions by affecting the part of the brain responsible for emotional regulation.
Highly sensitive people feel happiness, sadness, frustration, and other emotions more powerfully. They also absorb emotions from people around them, which makes them intensely empathetic but also more prone to crying in response to other people’s pain, touching stories, beautiful music, or even a kind gesture. If you’ve always been a crier, even as a child, and you also tend to feel overwhelmed by loud environments, notice subtle changes in people’s moods, or need downtime after social events, high sensitivity is a likely explanation.
Pseudobulbar Affect
If your crying feels truly involuntary, explosive in onset, short in duration, and wildly out of proportion to what you’re actually feeling inside, you may have a neurological condition called pseudobulbar affect (PBA). People with PBA burst into tears (or laughter) that doesn’t match their internal emotional state. You might cry intensely at something only mildly sad, or laugh uncontrollably in a serious moment.
PBA develops as a result of brain injury or an underlying neurological condition. The crying episodes are caused by disruption to the brain circuits that regulate emotional expression. It’s distinct from depression because the tears aren’t driven by persistent inner sadness. They’re more like misfired signals. PBA is relatively uncommon in the general population, but if the pattern sounds familiar, especially if you have a history of neurological injury or disease, it’s a recognizable and treatable condition.
Nutritional and Physical Factors
Low levels of B vitamins, particularly B12 and folate, play a role in producing brain chemicals that regulate mood. While the research on whether B12 supplements can directly ease depressive symptoms is mixed, a deficiency can contribute to low mood and emotional instability. If your diet is limited, you follow a vegan or vegetarian diet without supplementation, or you have absorption issues, a nutrient gap could be compounding your emotional reactivity.
Thyroid dysfunction is another physical cause worth noting. Both underactive and overactive thyroid conditions can produce mood swings, tearfulness, and anxiety. These are easily identified through blood work and highly treatable, yet frequently overlooked as a cause of emotional changes.
How to Tell What’s Driving Your Crying
Start by looking at the pattern. Track when you cry, what triggered it (if anything), where you are in your menstrual cycle if applicable, and how much sleep you got the night before. A few weeks of this data can reveal connections that aren’t obvious in the moment.
Consider the timeline. If you’ve always been a frequent crier but it doesn’t cause you distress or interfere with your life, high sensitivity or your natural temperament is the most likely explanation. If the crying is new or has escalated recently, look for what changed: a new medication, a stressful period, disrupted sleep, a hormonal transition, or a loss you haven’t fully processed.
Pay attention to whether the crying matches what you feel inside. Depression-related crying comes with genuine sadness or emptiness. Stress-related crying comes with a sense of being overwhelmed. PBA-related crying feels disconnected from your actual emotions, almost like it’s happening to you rather than coming from you. These distinctions matter because they point toward different solutions, from lifestyle adjustments and therapy to medical evaluation and treatment.
