Bees are major pollinators of fruits, vegetables and nuts. Without these helpful buzzing insects, our food supply would be in trouble.

But bees can help humans in another way. Researchers say the act of beekeeping may help people with mental health problems such as stress, anxiety and depression. Many call it "beekeeping therapy."

One group of people is especially getting help from such therapy: military veterans.

Many soldiers returning from military service have trouble dealing with the experiences of war. They may also have trouble creating a productive life after the military. Homelessness, depression and drug abuse can affect some military veterans.

Vince Ylitalo is one such veteran. He served in the military for nearly 40 years, including two tours in Iraq. He suffers from Post-Traumatic Stress Disorder, or PTSD.

To treat his PTSD, Ylitalo is part of a beekeeping program at the Manchester Veteran Affairs (VA) Medical Center in the state of New Hampshire. The VA has set up several such programs in the United States.

In a recent report by the Associated Press, Ylitalo explained how beekeeping calms his mind.

"I'm in this program to help me get out of the thought process of all those problems that I have. It helps me think about something completely different ... I'm just thinking about the bees."

Another veteran in the beekeeping program is Wendi Zimmerman.

She also says that beekeeping calms her mind. She calls the uncontrolled, unwanted thoughts from the past "clutter." She said the buzzing of the bees helps to clear the clutter.

"The buzzing – it fills that void in my head where clutter can go. So, instead of thinking of the things that clutter my brain or the experiences that clutter my brain ... I think of the bees."

Another beekeeping program based in the state of Michigan is Heroes to Hives. Adam Ingrao, a military veteran and insect expert, founded that program.

"All of these bees will die. These are our summer bees. And they only live 45 to 60 days."

He runs it through Michigan State University. The free program provides a nine-month beekeeping course to veterans.

Ingrao explains that beekeeping serves veterans in many ways.

"We're focused on empowering veterans to take control ... of their own lives ... by being able to practice mindfulness and slow down but also by giving them the opportunity to have their own business. ... This is a place for community. This is a place for healing. It's also a place for learning how to keep bees."

Beekeeping for soldiers returning from WWI

Beekeeping programs aimed at helping military veterans are not a new thing. In fact, the U.S. government had a program that taught beekeeping to soldiers returning from the First World War. Other countries at that time had similar programs.

There is little scientific evidence that beekeeping helps with PTSD or other mental health conditions. But that does not seem to matter to those who find comfort in beekeeping.

Veteran and beekeeper Frank Bartel does not need a study to prove the effectiveness of beekeeping therapy. For him, watching the bees relaxes his brain.

"When things get really hectic, crazy and you want to relax, you just put your chair out in front of the bee hive and watch them go in and out. And it's so relaxing. All your cares just float away."

Harvard researchers appear to agree with Frank's description.

On the website Harvard Health Publishing from the Harvard Medical School, researchers note studies that show the brain benefits of watching nature.

They write that those people who take a walk in nature, for example, would show less activity in their prefrontal cortex. This area of the brain is active during repetitive thoughts that lead to bad feelings.
