Crying more than usual is almost always a signal that something has shifted, whether in your body, your stress levels, your sleep, or your emotional health. It doesn’t necessarily mean something is seriously wrong, but it does mean something deserves your attention. The average woman cries 30 to 64 times per year, while the average man cries 5 to 17 times, according to self-reports from more than 7,000 people across 37 countries. If you’re noticeably above your own baseline, several explanations are worth considering.
Your Brain on Too Little Sleep
Sleep deprivation is one of the most common and underestimated reasons people become more tearful. When you don’t get enough rest, the part of your brain that processes emotions (the amygdala) becomes significantly more reactive to negative experiences. At the same time, the connection between the amygdala and the prefrontal cortex, the region that helps you regulate your reactions, weakens. The result is that situations you’d normally brush off can suddenly feel overwhelming.
This isn’t a subtle effect. Research published in the Journal of Neuroscience found that sleep-deprived people show exaggerated neural and behavioral responses to negative stimuli, and even their physical stress markers (like pupil dilation) spike more dramatically when viewing upsetting images. If you’ve been sleeping poorly for even a few nights, that alone could explain why your emotional threshold has dropped.
Stress, Burnout, and Emotional Exhaustion
Chronic stress gradually erodes your ability to cope with things that wouldn’t normally bother you. When your nervous system has been running in fight-or-flight mode for weeks or months, even a mildly frustrating email or a sentimental commercial can push you over the edge. This is especially true with burnout, which goes beyond ordinary tiredness. Burnout involves physical and emotional depletion, a sense of detachment from the people and work around you, and a feeling that nothing you do matters. You might notice you’ve lost patience, feel drained no matter how much rest you get, or have started using food, alcohol, or scrolling to numb yourself.
Frequent crying in this context is your body’s pressure valve. When emotional exhaustion builds without an outlet, tears become the default release. If your crying tends to happen after long work stretches, on Sunday nights, or during moments when you finally stop being “on,” burnout is a likely contributor.
Depression and Anxiety
Persistent tearfulness is one of the hallmark symptoms of depression. The distinction between a rough patch and a depressive episode comes down to duration, intensity, and interference. Depression involves symptoms that occur most of the day, nearly every day, and are severe enough to cause noticeable problems at work, in school, in social settings, or in relationships. Crying spells that come with sadness, emptiness, hopelessness, or a loss of interest in things you used to enjoy point toward something more than stress.
Anxiety can also lower your crying threshold. When your body is constantly flooded with stress hormones, your sympathetic nervous system stays activated. You’re essentially living in a heightened state where emotional stimuli hit harder. People with anxiety often describe crying “out of nowhere,” which usually means the underlying tension has been building invisibly until something small triggers the release.
If your increased crying has lasted more than two weeks, comes with changes in sleep, appetite, energy, or concentration, and makes daily life feel harder to manage, a mood disorder is worth exploring with a professional.
Hormonal Changes
Hormones directly influence how easily you cry. Prolactin, a hormone involved in tear production, is found at higher levels in emotional tears compared to the tears your eyes produce for lubrication. Fluctuations in estrogen, progesterone, and thyroid hormones all affect emotional reactivity, which is why crying spells are common during the premenstrual phase, pregnancy, postpartum, perimenopause, and after starting or stopping hormonal birth control.
Thyroid disorders are another hormonal cause that’s easy to miss. An underactive thyroid can produce depression-like symptoms including tearfulness, fatigue, and brain fog. If your crying feels out of proportion to what’s happening in your life and you also notice unexplained weight changes, temperature sensitivity, or sluggishness, a simple blood test can rule this out.
Nutritional Gaps That Affect Mood
Certain nutrient deficiencies can quietly destabilize your emotional baseline. Vitamin B12 deficiency causes irritability, mood changes, and cognitive decline alongside its more well-known symptoms like fatigue, nerve tingling, and numbness. This deficiency is especially common in vegetarians, vegans, older adults, and people taking certain medications that reduce stomach acid. Magnesium and vitamin D deficiencies have also been linked to increased emotional reactivity and low mood. If your diet has changed recently, or you’ve been eating less due to stress or appetite loss, nutritional gaps could be compounding the problem.
When Crying Doesn’t Match How You Feel
There’s a specific condition where people cry uncontrollably in situations that don’t match their internal emotional state. Pseudobulbar affect (PBA) is a neurological condition that causes outbursts of crying or laughing that feel involuntary and disproportionate. You might burst into tears during a casual conversation or laugh at something sad. PBA develops from disruptions in the brain pathways that control emotional expression and is associated with conditions like traumatic brain injury (affecting up to 48% of those patients), multiple sclerosis (up to 46%), ALS (up to 50%), stroke, Parkinson’s disease, and dementia.
PBA is distinct from depression, though they can coexist. The key difference is that with PBA, the crying episode feels disconnected from what you’re actually feeling inside. If this sounds familiar, especially if you have a history of any neurological condition or brain injury, it’s worth bringing up specifically, because PBA is frequently misdiagnosed as depression.
What Crying Actually Does to Your Body
Crying isn’t just an emotional response. It’s a physiological process with measurable effects. Emotional tears contain higher concentrations of stress hormones and natural painkillers (specifically, a type of endorphin) than the baseline tears that keep your eyes moist. This is part of why a good cry often leaves you feeling calmer afterward. The act of crying also helps shift your nervous system from its activated, fight-or-flight state toward the parasympathetic mode, which lowers your heart rate and promotes a sense of calm.
So crying itself isn’t the problem. The question is what’s driving it. A single explanation rarely accounts for a noticeable increase in tearfulness. More often, it’s a combination: you’re sleeping less, under more pressure, eating worse, and your hormones are shifting, all at the same time. Each factor lowers your threshold a little more until you find yourself tearing up at things that never would have gotten to you before. Identifying which of these factors apply to you is the most useful step toward feeling more like yourself again.
