Typically is associated with the darker evenings and cooler temperatures of the winter; but summer can bring about the same symptoms of depression for some people.

Extreme heat "impacts very basic comfort levels," especially once temperatures exceed 80 degrees, says Smriti Joshi, licensed clinical psychologist and chief psychologist at Wysa, a mental health app.

It doesn't help that we're seeing higher temperatures than normal due to climate change, she adds. "There's a lot of feeling of helplessness and loss of control because [of] weather changes and climate change that's been happening globally that can trigger a lot of anxiety," Joshi tells CNBC Make It.

Here are some symptoms of summertime (SAD)ness that you should be aware of, she says.

"Heat can lead to heat stroke and dehydration which can also have an impact on mental health," says Joshi. "That can also lead to a lot of stress and anxiety."

When the weather rises in the summer, "more instances of road rage happen," she adds. Collectively, people resort to unhealthy coping mechanisms like substance use, drinking more alcohol and either over-eating unhealthy foods, including ice cream, or not eating enough, says Joshi.

Certain groups that are more at-risk of heat stroke in extreme heat, like pregnant people and older individuals, are also more likely to stay inside on really hot days, and this can cause them to feel lonelier, she notes.

These are a few recommendations from Joshi for fighting off the symptoms of SAD that can affect you during the summer:

"At this point in time, there can be an increase in both physical health and mental health incidences," says Joshi. "The simple things which people often forget can be really helpful."
