The Surprising Benefits of Crying, According to Science

Why letting it out can sometimes help you feel more balanced.

We’re all guilty of needing a good cry every now and then. Whether you've just received some upsetting news or can't help but well up at a sad scene in your favourite rom-com (Marley & Me, anyone?), crying has actually been shown to have some helpful health benefits for humans.

A little-known fact is that our bodies can produce three types of tears – basal (to keep your eyes moist), reflex (to flush out irritants like wind and smoke) and psychic (in response to emotional distress).

Other than feeling like you've had a grand piano-sized weight lifted from your chest, we've done some digging into what is actually happening inside your body when you cry.

1. It helps you sleep

Crying can be a full-body workout sometimes, especially when you're in a state where you're no longer in charge of the tears coming from your body. Your shoulders are probably bouncing up and down and your cheeks might even get sore when you're in full blubber mode. As well as that, your heart rate naturally rises when you're crying because of your body's in-built fight-or-flight response to what caused the crying in the first place. Because of that, once you wipe away the tears and calm down, you might find it much easier to drift off to sleep because you've tired yourself out in the process.

2. Crying releases toxins

If you find yourself bawling your eyes out because of a particularly stressful situation in your life, your tears will actually contain a number of stress hormones and other chemicals, research suggests. Scientists who have studied the effects of crying on the body believe that letting yourself cry when faced with stress can reduce these hormone levels in the body and, in turn, lower your overall stress levels.

3. It can relieve pain

Oxytocin, or the 'love hormone', promotes feelings of bonding and wellbeing in our bodies and brains. Psychology researchers from various universities have proven that when we shed emotional tears, oxytocin, as well as the feel-good hormone endorphins, are released at the same time. This explains why, after a cathartic bout of crying, you actually feel better because your tears act as a natural pain healer.

4. And calm you down

Self-soothing is the act of regulating your own emotions when faced with difficult or upsetting circumstances, and be tricky for us humans to get a grip on sometimes. This study found that crying is one of the best ways to self-soothe when times are tough. To get technical for a moment, crying stimulates the parasympathetic nervous system, which helps to calm you down and regroup.

It turns out that holding our tears back in stressful, sad or painful situations isn't as healthy as letting it all out. Crying is a totally normal part of our human existence, and by letting your body respond automatically with tears, you'll feel better in more ways than one.
