Your heart rate can reach 200 beats per minute. In addition, your blood pressure rises, which has an effect on the vessels in your brain.
While you cry, you use a lot of facial muscles, which causes tension headaches. It is sometimes said that this is an important difference between crying spells in adults and children.

After crying you sometimes have a stuffy nose and your cavities can fill up. It can be compared to a bad cold, which can also cause a hefty headache.
