我一直以為隻要跑步就有Runner's High，因為我經常有體驗到。看了樓下的貼才知道並不一定每個人都有。狗一下RunnerHigh的定義，是這麽說的：
-
A runner’s high is a feeling of euphoria, relaxation and reduced anxiety during or after any type of aerobic exercise.
-
New research suggests it’s caused by endocannabinoids, or chemicals in your body that affect mood by crossing the blood-brain barrier.
-
Increase your chance of a runner’s high by varying your workouts and exercising for longer amounts of time.
我的體會也是如此，一般早起跑步後最明顯。跑完了感覺渾身的每個細胞都很舒服，既平和又亢奮。整個一上午幹什麽都很positive。雖然我沒體驗過大麻，周圍很多人都有體驗。應該是和吸食大麻後的感覺很類似，畢竟也是由cannabinoids類的物質產生的麽。和飲酒和性興奮還是不一樣的。runners high也沒有那麽addictive，說不跑就不跑了，沒覺得失去什麽。
