If reducing stress has been on your summer-to-do list,there’s one powerful thing you can still do before the season ends:get in the habit of taking a walk outside with a friend.
A quick walk in nature with a friend combines three of the most effective stress-reducing and resilience(恢复力)building techniques:physical exercise,spending time in nature and social connection.The activity works by helping normalize the hormonal changes that result from long time stress and enhancing the emotional resources that help us cope.
Walking quickly activates(激活)the body’s stress response.And when the walk is over,the stress system comes back down to the baseline.Regular exercise helps your stress response become more efficient,says Jennifer Heisz,associate professor at McMaster University.
As little as 10 minutes of sitting or walking in nature can decrease a person’s heart rate,blood pressure and cortisol levels,as well as self-reported stress levels.One possible explanation,the researchers say,is that spending time in nature lowers the activity of our sympathetic nervous system,which regulates stress hormones,and taps into the parasympathetic(副交感)nervous system,which promotes our calm and relaxation responses.
Taking that hike with a loved one can further reduce stress by adding the important element of social connection.Talking with trusted friends helps people process stressful events and lifts self-esteem.Social support has positive effects on the brain and body,scientific research finds.
