Youth Info

Mood swings—when a person’s feelings change quickly and might feel very intense—are a normal part of puberty. You might feel moody, crabby or even suddenly want to cry and then feel fine or happy. These mood swings are often caused by hormones, and they are totally normal while you’re going through puberty.

Frequently Asked Questions

What are mood swings?

Mood swings are when a person’s mood changes very quickly. That can include going from one extreme (like angry) to another extreme (like happy). These shifts in mood can happen quickly and feel intense. Mood swings are a normal part of puberty. It’s important to be patient with yourself and others who might be experiencing mood swings.


Why do people get mood swings?

During puberty, the process in which a person grows into an adult, the brain starts to make a lot more hormones. Hormones are the body’s chemical signals that tell certain body parts to grow, and they also affect the part of the brain that manages feelings or moods. This increase in hormones can often lead to mood swings. This is all perfectly normal and tends to even out once a person is done with the changes of puberty.


How can I deal with having mood swings?

Experiencing mood swings can be exhausting. So it’s good to keep in mind that mood swings are a perfectly normal part of puberty and growing up. Talking about your feelings with friends and trusted adults can help, as can remembering that you’re not alone in dealing with mood swings. Almost everyone going through puberty will deal with mood swings at some point or another.

If you ever feel sad for most of the time, then it’s good to talk with a trusted adult or a counselor to check for something called depression. Depression is when someone feels sad most or all of the time. There are ways to help people experiencing it, so it’s important to ask for help.

Parent Info

During puberty, young people experience many physical and emotional changes as they pass from childhood into adulthood. Many of these changes are a result of hormones, the chemicals in a person’s body that communicate to certain body parts how to grow and change. Hormones play an important role during puberty, and it’s normal for young people’s bodies to go through lots of hormonal fluctuations while they’re growing up.

Mood swings—the quick change of a person’s feelings, sometimes from one extreme to the next—are often the result of increases in certain hormones. This is because hormones affect the limbic system in the brain, the area that controls the regulation of feelings. So young people might be really excited and happy one minute and then feel angry and upset another. Sometimes it can feel like the smallest thing can trigger an intense response from a young person going through puberty. This is all normal due to the new levels of hormones in the body.
