Frequencies of Crying
STEP: 01
START OF CRYING
High Beta Waves (20-30 Hz)
A wave of heightened stress, fear,
or intense emotion triggers crying.
STEP: 02
DURING CRYING
Low Beta Alpha Waves (8-15 Hz)
he act of crying acts as an emotional
release valve and tells the brain to
transition from stress to processing.
STEP: 03
RIGHT AFTER CRYING
Alpha Theta Waves (4-12 Hz)
After crying, the brain shifts into calm alpha
waves (8-12 Hz), while the parasympathetic
system slows the heart rate. During deeper cries,
theta waves (4-8 Hz) turn on emotional healing
and introspection and can bring unresolved
feelings to the surface
STEP: 04
DURING CRYING
Delta Waves (0.5-4 Hz)
Activation of the parasympathetic
system makes it easier to transition into
rest or sleep, triggering delta waves
which helps physical recovery.
Brain Waves During Crying: Step-by-Step Emotional Reset
STEP 01: START OF CRYING – High Beta Waves (20–30 Hz)
Initially, the brain waves during crying at the very first signs of tears often show increased arousal and distress. Beta waves, generally oscillating between 13 and 30 Hz, are linked with active thinking, being externally focused, and elevated levels of anxiety or stress. In this starting period, the overwhelming feeling is reflected by a burst of very high beta that represents intense emotion, fear, or emotional saturation because the nervous system is shifting into a mode of alarm and emotional overload.
STEP 02: DURING CRYING – Lower Beta and Emerging Alpha (Around 8–15 Hz)
In the middle of one crying session, brain waves during crying may change that stressed, high beta frequency to lower beta and also alpha activity. Alpha waves fall between roughly 8 and 12 Hz, are indicative of calm wakefulness and a more relaxed way of being focused internally. Crying serves as a kind of emotional vent, which supports the brain in moving from the state of acute stress to a phase of processing, reflecting, and gradually lowering the level of arousal.
STEP 03: RIGHT AFTER CRYING – Alpha and Theta Waves (4–12 Hz)
After the emotional peak, recovery from crying the brain waves tend to show more dominant alpha and sometimes theta activity. Alpha (8, 12) waves are linked with relaxation and reduced monitoring of threats from the outside, while theta waves (4, 8) are related to deep relaxation, emotional insight, and inward focus. Research shows that parasympathetic activation is often increased after tearful crying, slower heart rate, calmer breathing, which allows emotional soothing and restoration. It is believed that this calmer alpha, theta mixture helps the person to emotionally process, reflect, and bring up unresolved feelings in a safe internal environment.
STEP 04: REST AND SLEEP AFTER CRYING – Delta Waves (0.5–4 Hz)
If crying leads to a deep rest or sleep, brain waves during the resolution of crying may change to delta frequencies. Delta waves (0.5, 4) are characteristic of a deep, restorative sleep during which the body heals itself and consolidates both emotional and physical recovery.
Since parasympathetic activation increases during tearful episodes, it is easier to sleep after crying. Therefore, the delta activity can come from a full, body reset and healing.
Thus, brain waves during crying overall transition from high, alert beta to the more relaxed alpha, introspective theta, and eventually deep, rest delta if sleep follows. Such a brain wave pattern helps to understand why a crying session can leave you feeling refreshed, relaxed, and emotionally regulated.

Psychological and neurobiological research on crying suggests that shifts in autonomic balance—especially increased parasympathetic activation—play a key role in why crying sometimes improves mood and promotes emotional recovery, supported by changes in brain waves during crying and afterwards.
