Why Does Crying Make You Tired

This is one of the most common questions that people ask themselves. If you’re feeling overwhelmed or sad, crying often helps to relieve stress, but what happens when you cry? We know that tears are an important part of our body’s production of a hormone called oxytocin. Oxytocin can be viewed as an anti-stress hormone because it reduces the body’s response to stress. When we cry, our bodies release this hormone and make us feel more relaxed. But what does this have to do with how tired we feel after crying? Here are some insights about why crying makes us tired so you can learn if this is true for you and your loved ones.

Why does crying make you tired?

There are many biological reasons as to why crying can make you tired. When we cry, it produces hormones that help us feel happy and alive, but it also makes us feel tired.

What Happens After You Cry?

  1. Your body can release more oxygen and nutrients into your muscles.
  2. You may feel slightly more energized after you cry.
  3. Your body can release more hormones, which can help with feelings of sadness and fatigue that you get from crying.
  4. When we cry, there is an increase in blood flow to the muscle tissues, which helps us feel a little bit better after crying has ended
  5. These hormones released during the crying process make us feel sad or happy (depending on the circumstances), which can lead to feelings of sadness and fatigue after having cried
  6. These hormones that are released when we cry also contribute to feeling tired after crying has ended because they do so by causing our bodies to produce less energy than normal
  7. Some people might have allergies that cause them to sneeze or cough more than usual when they cry and this can lead to feeling too exhausted for certain activities such as exercise for example.
  8. Some people can experience this feeling of tiredness and sadness after crying because their bodies are overreacting to the hormones that are released during the process of crying.

Why Do You Feel Tired After Crying?

  • The first reason why you feel tired after crying is that there is a release of hormones in your body. This can lead to feeling fatigued, though this effect may vary from person to person.
  • The second reason why you feel tired after crying is that when you cry, your muscles contract involuntarily which leads to feelings of stress and tension. The release of these hormones is also likely to cause an increase in heart rate as well as an increase in perspiration.
  • Thirdly, when we are sad, our brain releases dopamine or serotonin which helps us feel better and ensures we take on positive thoughts and emotions. When these two chemicals are released into our system during the crying process, it can lead to feelings of fatigue or drowsiness.
  • Fourthly, when we cry, it triggers endorphins which are natural chemical substances that help reduce pain by creating a feeling of euphoria and happiness. These endorphins can make us feel energized again.
  • Finally (and lastly), some people might have allergies that cause them to sneeze or cough more than usual when they cry and this can lead to feeling too exhausted for certain activities such as exercise for example.

The Science Behind Tears

  1. The tears that come from crying are made up of three different types of liquid: water, saltwater, and mucus. Tears contain a chemical called serotonin which is released in the moments before crying. This chemical creates the sensation of feeling happy or sad (depending on the circumstances) after a person cries. The production of this chemical is what leads to feelings of sadness and fatigue, which both contribute to why crying makes us tired.
  2. Another key component in how we feel after crying is hormones that are released in our brain. This can be done by interacting with other people and being around them, which triggers your body to release these hormones when you cry.  If a person has an anxiety disorder, it can lead to a spike in hormone levels that increase their likelihood of feeling tired after crying
  3. Finally, blood flow changes can cause feelings of sadness and fatigue from crying as well. In order to produce tears, there is an increase in blood flow while they’re happening. This increase in blood flow leads to more oxygen getting into our muscles and cells, which helps us feel energized after we are done crying. On the other hand, when there is less blood flow during one’s cry session, it can lead to feeling tired afterward through a lack of oxygen and resources entering the muscle cells.

What Are The Benefits Of Crying?

Crying can have a number of benefits. Crying is a natural process that releases endorphins which are hormones that make us feel good. Another benefit is that it helps clear the mind and help reduce stress or anxiety levels unless the person has been crying for an extended period of time.

  • Crying is a natural reaction that all humans go through.
  • Crying can be done in private, without fear of causing embarrassment to anyone else.
  • Crying will not make someone feel bad or shameful because it is a normal human reaction that needs to be expressed and released.
  • It helps us release negative feelings and emotions that we are experiencing, whether they be positive or negative feelings and emotions.
  • It can lead to a “clean slate” when we start anew with new beginnings, as well as help us feel less stressed and anxious about the future of our lives.
  • Cries can help relieve symptoms of depression by making people feel happier and more energized after crying out their frustrations from being sad or depressed for too long within their lives (Bancroft). By crying, they are able to release the sadness they are feeling and release it into the water through tears; which leads them to feel happier again.
  • Crying can be done for fun so that it is not a life-threatening or serious problem to people.
  • Crying can help relieve stress, anxiety, and depression in a person’s life.
  • Crying can be done to express emotions, thoughts, and feelings that they may have within their lives.
  • Crying can help relieve symptoms of anxiety by making people feel more confident about themselves and what they are doing in their lives (Bancroft). By crying out their worries and fears, they are able to release all of their feelings that have been causing them pain and suffering for too long within their lives; which leads them to feel more confident again about what is going on in their lives.


The science behind crying is complex, but understanding the biological reactions that happen after you cry is key to avoiding tiredness after crying. It is well known that crying can help relieve stress and release endorphins and dopamine, which in turn may make you feel better. But contrary to the belief that crying will make you feel more tired, crying actually has a number of benefits. Some of these benefits include sleep and less pain.
