Addiction may be treated with exercise

Cardio said to be effective against drug and alcohol addiction

Scientists have suggested through a study that aerobic exercise can help treat drug or alcohol addiction by altering the brain’s reward system.

Aerobic exercise is popularly known as “cardio” in which brisk exercise that increases heart rate, breathing and circulation of oxygen through the blood, is carried out. Cardio is associated with decreasing many negative health issues, including diabetes, heart disease and arthritis. It also is linked to numerous mental health benefits, such as reducing stress, anxiety and depression.

Scientists at the University at Buffalo in the US identified a key mechanism in how aerobic exercise can help impact the brain in ways that may support treatment and prevention strategies for addiction.

“Several studies have shown that, in addition to these benefits, aerobic exercise has been effective in preventing the start, increase and relapse of substance use in a number of categories, including alcohol, nicotine, stimulants and opioids,” said Panayotis Thanos, senior research scientist at University at Buffalo.

“Our work seeks to help identify the underlying neurobiological mechanisms driving these changes,” Thanos said.

Using animal models, researchers found that daily aerobic exercise altered the mesolimbic dopamine pathway in the brain.

Dopamine is a key neurotransmitter associated with substance use disorders, playing an important role in reward, motivation and learning.

“Current work is looking at whether exercise can normalise dopamine signalling that has been changed by chronic drug use, as this may provide key support of how exercise could serve as a treatment strategy for substance abuse,” he said.

“Further studies that focus on people with substance use disorders should help researchers develop new methods to integrate exercise into treatment regimens that may help prevent relapses,” Thanos said.
