Have a good cry. It can be good for you.
Crying is a natural response to emotions like joy and sorrow – and irritants like dust in the eyes, says Medical News Today.
Humans produce three types of tears:
Basal: The tear ducts constantly secrete basal tears, which are a protein-rich antibacterial liquid that help to keep the eyes moist every time a person blinks.
Reflex: These are tears triggered by irritants such as wind, smoke, or onions. They are released to flush out these irritants and protect the eye.
Emotional: People shed tears in response to a range of emotions. These tears contain a higher level of stress hormones than other types of tears.
Crying has its benefits.
A 2014 study found that crying may have a self-soothing effect on people. The study explained how crying activates the parasympathetic nervous system (PNS), which helps people relax.
Crying can help people get support from others around them.
Crying can also relieve pain. Research has found that shedding emotional tears releases oxytocin and endorphins. These chemicals make people feel good and may also ease both physical and emotional pain.
Crying may make one feel better. Besides relieving pain, oxytocin and endorphins can help improve mood. This is why they are known as “feel good” chemicals.
Crying releases toxins and relieves stress. When people cry in an outpouring of emotions, their tears contain a number of stress hormones and other chemicals.
Crying aids sleep. A study in 2015 found that crying can help babies sleep better.
Crying helps to kill bacteria and keep the eyes clean as tears contain a fluid called lysozyme.
Crying improves vision. Basal tears, which are released every time a person blinks, help to keep the eyes moist and prevent mucous membranes from drying out.
Crying can be good – but it can be too much of a good thing. Ffrequent crying may be a sign of depression. Then one has to see a doctor.
