Stress and its Effects on the Body

Stress is how the brain and body react to the daily pressures of life. These pressures may include school, work, family, daily responsibilities as well as the positive pressures of navigating a new relationship, planning a vacation or moving.

Stress can be short term from a one time event (break-up, illness, pandemic) or it can be ongoing and chronic (long term illness, job stress). Not all stress is bad and it is designed to give cues to our body that we need to become aware and motivated to face the challenge ahead. Physical manifestations in the body such as heart rate and breathing getting quicker, brain using more oxygen and muscles getting tense are common during acute stress.

Chronic Stress

Chronic stress can be harmful to the body over time.

  • Increased cortisol and adrenaline can cause long term increase to the heart rate, blood pressure and glucose levels in the body.
  • Increased cortisol over time can raise pro-inflammatory markers in the body increasing the chance for heart disease and diabetes
  • Overstimulated immune system from a cytokine storm which may decrease the body's ability to fight illness and may promote depression

Reducing Stress, Promoting Health

Movement

  • Exercise and movement reduce inflammation by leading to an anti-inflammatory response.
  • Exercise and movement promote neurogenesis and help to the production of new brain cells primarily in the hippocampus.
  • Yoga promotes deep relaxation and focuses on movement and breathwork counteracting the harmful effects of chronic stress.
  • Movement includes PLAY! Doing fun activities such as walking your dog, frisbee with friends, or swinging on the playground all decrease inflammation and promote wellness.

Connection

  • Connecting with safe relationships in our lives promotes a feeling of belonging and lowers the stress hormones.
  • Feeling part of a bigger community whole helps create a wider lens in which to view life through rather than focusing on one's own problem.

Education

  • Having strong cognitive reserves has been proven to promote mental wellness and is protective against depression and anxiety.
  • Cognitive reserves are mental stores that we gather throughout our lives that help us see problems and solutions in creative and open-minded ways. Examples of this are either-and thinking versus either-or thinking.

Mindfulness and Giving

  • Mindfulness practice promotes a feeling of gratitude and curiosity about the world.
  • Giving back to a charity or community project promotes positive feelings about life and activates the reward system in the brain.

Nutrition

  • Adding in more anti-inflammatory foods in one's diet promotes healing at the cellular level.
  • Avoiding pro-inflammatory foods such as sugar, processed foods and unhealthy fats can help prevent inflammation in the brain and body.

Sleep

  • Focus on getting 7-8 hours of good quality sleep a night.
  • Establish a regular bedtime routine to signal to the brain that it is time to become quiet and ready itself for rest.
  • Avoid screen time 2 hours prior to bed including cell phones, laptops, and gaming all of which can be activating to the brain. Alternative activities include reading before bed, listening to audiobooks, listening to relaxing nature sounds or doing a guided body relaxation meditation
