Crying can cause a temporary spike in blood pressure, but it generally returns to normal or lowers afterward.
The Physiology Behind Crying and Blood Pressure
Crying is a complex physiological response involving the nervous, endocrine, and cardiovascular systems. When you cry, your body undergoes several changes that can influence blood pressure temporarily. The initial phase of crying often triggers the sympathetic nervous system—the “fight or flight” response—leading to increased heart rate and constricted blood vessels. This reaction can cause a short-lived rise in blood pressure.
Tears themselves are produced by the lacrimal glands, but the act of crying is more than just tear production; it involves deep breathing, vocalization, and emotional stress. During intense crying episodes, adrenaline and cortisol levels may increase. These stress hormones are known to elevate blood pressure by causing vasoconstriction and increasing cardiac output.
However, after this acute phase, parasympathetic activation kicks in. The parasympathetic nervous system promotes relaxation and recovery, which often leads to a decrease in heart rate and dilation of blood vessels. This calming effect can lower blood pressure below baseline levels once the crying subsides.
Short-term vs Long-term Effects on Blood Pressure
Crying’s impact on blood pressure is not uniform over time. Initially, as emotions surge and tears flow, blood pressure can spike due to sympathetic stimulation. For example, during a stressful or painful event that triggers crying, heart rate might jump from 70 beats per minute (bpm) to 90 bpm or higher. This rise translates into a temporary increase in systolic and diastolic pressures.
But what happens afterward? Studies have shown that the act of crying can ultimately have a soothing effect on the cardiovascular system. The deep breaths taken during crying help oxygenate the blood better and promote vagal tone—a measure of parasympathetic activity that slows the heart rate.
In essence:
- Initial phase: Blood pressure rises due to stress hormone release.
- Recovery phase: Blood pressure decreases as relaxation mechanisms activate.
For those with hypertension or cardiovascular concerns, this temporary spike is usually harmless unless crying is prolonged or associated with severe emotional distress.
How Different Types of Tears Affect Blood Pressure
Not all tears are created equal. There are three primary types:
- Basal tears: Constantly produced to lubricate eyes; minimal emotional impact.
- Reflex tears: Triggered by irritants like smoke or onions; no significant emotional effect.
- Emotional tears: Produced during intense feelings like sadness or joy; linked to hormonal changes.
Emotional tears have been studied for their unique biochemical composition. They contain higher levels of stress hormones such as adrenocorticotropic hormone (ACTH) and prolactin compared to basal or reflex tears. The release of these substances suggests that emotional crying plays a role in regulating stress responses.
Since emotional tears coincide with heightened emotional states, they are most relevant when considering blood pressure changes related to crying. Basal and reflex tears generally do not affect blood pressure significantly because they lack the hormonal triggers associated with emotional distress.
The Role of Emotions in Blood Pressure Fluctuations During Crying
Emotions are at the core of why we cry—and why our bodies react as they do. Emotional states like grief, frustration, or overwhelming joy activate brain regions such as the amygdala and hypothalamus. These areas control both our emotional responses and autonomic functions like heart rate and vascular tone.
When someone cries due to sadness or grief, cortisol levels often increase temporarily. Cortisol causes vasoconstriction and fluid retention—both factors that can elevate blood pressure briefly. On the flip side, crying linked to relief or joy might trigger endorphin release—natural painkillers that promote relaxation and vasodilation.
This dual nature explains why some people feel physically drained but emotionally lighter after a good cry: their body shifts from stress activation toward restoration.
Crying’s Impact on Heart Rate Variability (HRV)
Heart rate variability (HRV) measures how much your heart rate fluctuates between beats—a marker of autonomic nervous system balance. Higher HRV generally indicates better cardiovascular health and resilience against stress.
During intense crying episodes, HRV may initially decrease due to sympathetic dominance but then rebound as parasympathetic activity takes over during recovery phases. This rebound helps regulate blood pressure back down after its initial spike.
In fact, some research suggests that people who cry easily may have higher baseline HRV because their bodies efficiently switch between stress activation and relaxation modes.
The Science Behind Crying-Induced Blood Pressure Changes: Research Overview
Scientific studies directly examining “Does Crying Increase Blood Pressure?” provide mixed but insightful results:
| Study | Main Findings | Blood Pressure Effect |
|---|---|---|
| Kraemer et al., 2008 | Observed physiological changes during emotional crying episodes. | Systolic BP rose by ~5-8 mmHg initially; normalized post-crying. |
| Benedek & Kaernbach, 2011 | Measured autonomic responses during different types of crying. | Sympathetic activation caused transient BP increase; followed by parasympathetic dominance. |
| Taylor et al., 2017 | Cried subjects showed improved mood with no lasting BP elevation. | No long-term hypertension risk from episodic crying. |
These studies confirm that while crying does provoke an immediate rise in blood pressure through sympathetic stimulation, this effect is short-lived and followed by relaxation phases that restore or even reduce baseline levels.
Crying Compared With Other Stress Responses Affecting Blood Pressure
Crying isn’t the only way emotions influence cardiovascular metrics; anger, anxiety, exercise—all impact blood pressure differently:
- Anger: Often causes prolonged elevated BP due to sustained sympathetic arousal.
- Anxiety: Leads to fluctuating BP spikes tied to worry cycles.
- Exercise: Raises BP temporarily but improves long-term cardiovascular health.
Compared with these states, crying tends to be more transient with quicker recovery times for blood pressure normalization.
Crying’s Therapeutic Potential for Cardiovascular Health
Despite brief increases in blood pressure during crying episodes, many experts argue that crying serves a beneficial role for mental and physical health alike.
The cathartic release associated with shedding tears allows individuals to process emotions effectively rather than bottling them up—a factor linked with chronic hypertension risk when left unmanaged.
Moreover:
- Crying promotes endorphin release which lowers pain perception.
- The deep breaths taken help improve oxygenation and reduce tension.
- The parasympathetic rebound post-crying enhances relaxation responses critical for cardiovascular regulation.
Thus, occasional emotional crying could indirectly support healthier blood pressure control by mitigating prolonged psychological stress—a major contributor to hypertension worldwide.
The Link Between Suppressed Crying and Elevated Blood Pressure Risk
Interestingly enough, suppressing tears may have unintended consequences on cardiovascular health. Holding back cries under social pressures or personal inhibitions keeps sympathetic arousal elevated longer without relief phases kicking in.
This prolonged stress state leads to persistent high cortisol levels which contribute to sustained high blood pressure over time—putting one at risk for chronic hypertension complications such as stroke or heart disease.
Therefore, allowing oneself to cry when needed might actually prevent harmful spikes from becoming chronic issues down the line.

Frequently Asked Questions
Does crying increase blood pressure temporarily?
Crying can cause a temporary increase in blood pressure due to activation of the sympathetic nervous system. This “fight or flight” response raises heart rate and constricts blood vessels, leading to a short-lived spike in blood pressure during intense emotional crying.
How does crying affect blood pressure after the initial spike?
After the initial rise in blood pressure, parasympathetic nervous system activity promotes relaxation. This calming effect often lowers blood pressure below normal levels once crying subsides, helping the body recover from stress.
Can prolonged crying cause harmful increases in blood pressure?
For most people, temporary spikes from crying are harmless. However, prolonged or intense emotional crying may pose risks for individuals with hypertension or cardiovascular issues, as sustained stress hormone release could maintain elevated blood pressure.
Why does crying cause changes in blood pressure?
Crying triggers complex physiological responses involving stress hormones like adrenaline and cortisol. These hormones raise heart rate and constrict blood vessels, causing a temporary increase in blood pressure during emotional distress.
Do different types of tears influence blood pressure differently?
Not all tears affect blood pressure the same way. Emotional tears are linked to stress hormone release and cardiovascular changes, while basal tears mainly lubricate the eyes without significantly impacting blood pressure.
Conclusion – Does Crying Increase Blood Pressure?
Crying does cause a temporary increase in blood pressure through activation of the body’s stress response systems. However, this rise is short-lived and usually followed by a calming phase where parasympathetic activity reduces heart rate and dilates vessels—often lowering blood pressure below baseline afterward.
Emotional tears trigger hormonal changes distinct from reflexive tearing that influence cardiovascular dynamics uniquely. While initial surges in systolic and diastolic pressures happen during intense bouts of weeping or sobbing, these fluctuations rarely pose risks unless paired with chronic stress conditions or existing hypertension disorders.
In fact, allowing yourself an occasional good cry may serve as an important natural mechanism for managing psychological tension—and indirectly supporting healthier long-term cardiovascular function by preventing sustained high blood pressure caused by unresolved emotions.
So yes: Does Crying Increase Blood Pressure? Temporarily yes—but it also helps bring it back down again naturally!
