Summertime is when the temperatures begin to rise, and the summer-fun activities roll around, but experts say people struggle during this time of year with mental health issues.

According to the National Institute of Mental Health, seasonal affective disorder is also known as SAD, which is a type of depression that occurs seasonally. NIMH states that the disorder is not as common in the Summer as it is in the Winter.

Experts say that many people keep this struggle to themselves.

"Some people don't feel well, aren't going to tell anybody and continue to feel lousy. So for those people, the first step would be to say to someone hey I don't feel right," said George Northrup, a Psychiatrist, and treatment-resistant depression expert.

The symptoms for those that experience SAD during the Summer include a loss of appetite, insomnia, agitation, restlessness, anxiety, and episodes of violent behavior, according to the NIMH.

To treat this disorder it is recommended to acknowledge any struggle of depression, while increasing social support, exercising, getting enough sleep, and eating better.
