Crying does appear to be good for you in several measurable ways. It triggers the release of oxytocin and endorphins, your body’s natural painkillers, which help ease both physical and emotional pain. It activates your body’s calming nervous system, signals others to offer support, and keeps your eyes healthy. But the benefits come with some important caveats, especially for people dealing with depression.
How Crying Eases Pain and Lifts Mood
When you cry emotionally, your brain releases oxytocin and endorphins. These chemicals are the same ones responsible for the warm feeling after a hug or the “runner’s high” after exercise. They dull pain and create a sense of calm, which is why many people describe feeling lighter or relieved after a good cry. This chemical release is specific to emotional crying, not the tearing up you get from chopping onions or a gust of wind.
Emotional tears themselves have a different chemical profile than the reflex tears produced by irritants. They contain higher levels of stress hormones, a natural painkilling compound called leucine-enkephalin, and minerals like potassium and manganese. The protein concentration of emotional tears is about 24% higher than irritant-induced tears. Some researchers have suggested this means crying literally flushes stress-related chemicals out of your body, though the quantities involved are small enough that “detox” is probably too strong a word for what’s happening.
The Calming Effect Takes a Few Minutes
Crying activates the parasympathetic nervous system, the branch responsible for slowing your heart rate, lowering blood pressure, and shifting your body into a restful state. This is the opposite of the fight-or-flight response that stress triggers. The catch is that this calming effect isn’t instant. It typically takes several minutes of sustained crying before you start to feel soothed, which explains why the first few moments of a cry can actually feel worse before they feel better.
This lag matters. If you suppress a cry before it runs its course, you may miss the self-soothing payoff entirely. The people who report feeling better after crying tend to be those who let it happen fully rather than cutting it short.
Tears as a Social Signal
Crying is almost certainly unique to humans, and researchers believe it evolved partly as a social tool. A large study spanning 41 countries confirmed that seeing someone cry reliably triggers the desire to help them. Observers perceived crying people as warmer and more helpless, felt more connected to them, and experienced greater empathy. The effect was consistent across cultures.
This “social glue” function may explain why humans keep crying well into adulthood, long after we can verbally ask for help. Visible tears communicate vulnerability in a way words often can’t, and they tend to strengthen bonds between people. Crying in front of someone you trust can deepen that relationship. Crying alone still provides the chemical and nervous system benefits, but you lose this social component.
How Often People Cry
Women cry an average of 5.3 times per month. Men average about 1.3 times per month. These numbers, which count everything from moist eyes to full sobbing, have stayed remarkably stable since they were first measured in the 1980s. The gap is likely driven by a combination of hormonal differences (prolactin, which is linked to crying, is higher in women) and cultural norms that discourage men from crying openly.
There’s no “right” amount of crying. If you rarely cry, that doesn’t signal a problem. If you cry frequently and feel better afterward, that’s a healthy release. What matters more is the pattern: a sudden increase in crying frequency, or crying that never brings relief, can point to something deeper going on.
When Crying Doesn’t Help
The assumption that “a good cry” always makes you feel better doesn’t hold up for everyone. Research on people experiencing clinical depression found that while crying and depressed mood often occurred together, crying did not reduce the depressed mood that followed. In other words, for people with depression, crying may reflect distress without relieving it.
Context also plays a role. Crying in a supportive, safe environment tends to produce the most relief. Crying in situations where you feel judged, embarrassed, or unable to stop can leave you feeling worse. The social setting, your emotional baseline, and whether you view crying as acceptable all influence whether tears bring catharsis or just exhaustion.
Tears Protect Your Eyes
Beyond emotional benefits, tears serve a straightforward physical purpose. They contain lysozyme, a powerful antimicrobial enzyme that attacks bacterial cell walls. Working alongside another protective protein called lactoferrin, lysozyme helps neutralize pathogens that land on your eye’s surface throughout the day. Basal tears (the thin layer constantly coating your eyes) do most of this work, but any type of crying flushes debris and keeps the cornea lubricated and nourished.
Manganese concentrations in tears are about 30 times higher than in blood serum, which is notable because elevated manganese levels in the body are associated with anxiety and irritability. Whether crying meaningfully lowers your overall manganese burden is debatable given the tiny volume of fluid involved, but the concentration difference is real.
