According to a new study published in the peer-reviewed journal JAMA, people who sit for extended periods of time are more likely to develop dementia than people who sit for shorter periods of time. Although this is now considered the standard in modern living, scientists warn that it can have a negative effect on brain health. Thus far, sedentary lifestyles have been linked to higher risks of heart disease, diabetes, stroke, and even mortality. Nevertheless, these kinds of behaviors can also lead to mental health problems such as mood disorders, sleep disruptions, cognitive decline, and increased stress.
Sedentary lifestyles can have the following effects on brain health:
- Cognitive deterioration
Sedentary lifestyles have been linked to an increased risk of cognitive decline and diseases including dementia and Alzheimer’s disease, according to studies. Frequent exercise has been associated with enhanced cognitive function, memory, and attention.
2. Calm
Exercise has been shown to release endorphins, which are organic mood enhancers. Sitting all the time restricts the flow of these hormones, which can lead to depression.
3. Mental well-being
Living a sedentary lifestyle can raise your chances of developing anxiety, depression, and other mood disorders. Furthermore, a sedentary lifestyle might increase stress and worsen mental health in general.
4. Decreased blood volume
All over the body, including the brain, increased blood flow is a result of physical exertion. Sedentary behavior can impair blood flow to the brain, which can decrease the amount of oxygen and nutrients that reach brain cells. Both general brain health and cognitive performance may be impacted by this.
5. Less neuronal plasticity
The brain’s capacity for self-organization and adaptation is known as neuroplasticity, and it is enhanced by physical activity. For the development of skills, memory, and learning, this is essential. Sedentary behavior can impede neuroplasticity and increase the brain’s difficulty in adjusting to novel situations.
6. Metabolic diseases and obesity
Living a sedentary lifestyle is frequently linked to weight gain and an elevated risk of obesity, both of which can result in a number of metabolic diseases, including type 2 diabetes. The health of the brain may be negatively impacted by several disorders, and cognitive impairment may become more likely.
7. Disturbances in sleep
A sedentary lifestyle might throw off sleep cycles. Insufficient sleep can negatively impact memory consolidation, emotional control, and cognitive performance, resulting in a range of mood and cognitive problems.
8. Enhanced anxiety
Chronic stress has been related to both structural and functional changes in the brain, especially in areas related to memory and emotion control. Sedentary lifestyles can exacerbate this stress.
