If you have ever gone through a breakup, you have probably experienced the five physiological reactions below. Usually these reactions would take anywhere between six months to two years to get over. However, every person reacts differently. 

1-Anxiety and insomnia

2-Chest pain

Chest pain is another symptom that takes place when you undergo a breakup. The neuron signals of people who’ve recently just got out of a relationship, are identical to the those that cause physical pain after a burn.

That’s why feeling chest pain after a breakup is no surprise. This takes place because your heart function actually worsens when undergoing this traumatic experience. Therefore, it’s actually dangerous for a person who has heart disease. Likewise, adrenaline may cause irregular heartbeats.

In several studies, the MRIs of the brains of people who were going through a breakup, revealed that there was brain activity in regions that control stress and physical pain.

The researcher observed that — even though the brain sector that perceives pain related to the outside world was inactive — the systems in charge of controlling the body’s response towards pain were causing patients a lot of anguish. This takes place due to the brain releasing stress hormones, which in turn directly have an impact on the heart, digestive system, and immune system.

3-Blemishes on the skin

4-Muscle pain

When you experience stress, you become more vulnerable to injury. You may even undergo muscle spasms during these situations. Therefore, this can cause your muscles to tighten or cramp and produce pain throughout the body.

5-Abnormal diet

Being overweight can also be related to insomnia and a lack of exercise. Stress interrupts the proper function of your digestive system. All of this may cause stomach pain and diarrhea.

Why do breakups hurt?

If you have ever wondered why a breakup causes so much pain, the answer is likely related to the chemical reactions that are triggered in the body. A breakup can even change your relationship with other people because you become anxious when interacting with them. You may undergo pain similar to a bone breaking when your significant other refuses to see you.

Consider that other types of social rejection operate more at a cognitive level. At the same time, romantic rejection is related to the same systems that cause you to feel hungry or thirsty.
