eachers；　laugh！

Psychologists　have　long　believed　that　negative　emotions　cause　negative　chemical　changes　in　the　body。　We　know　the　opposite　is　also　true。　We　know　that　a　person　with　a　good　sense　of　humor　has　better　healing　qualities。　Laughter　actually　relaxes　the　muscles；　slows　the　heartbeat；　and　lowers　blood　pressure。　Laugher　stirs　the　inside　and　gets　the　endocrine2　system　moving；　which　can　be　quite　beneficial　in　alleviating　disease。　Laughter　also　relieves　boredom；　tension；　guilt；　depression；　headaches；　and　backaches。

Each　time　you　chuckle　or　“crack　up”；　your　brain　releases　the　body’s　natural　pain…killing　hormones。　Those　hormones　trigger　the　release　of　endorphines；　natural　opiates　that　can　reduce　pain。　These　same　hormones　are　responsible　for　making　the　eyes　sparkle　and　getting　the　brain　to　work　more　eriectively。　Laughter　can　produce　a　great　deal　of　relaxation。　When　your　body　is　relaxed；　the　vista　broadens；　and　you　can　see　things　you　were　missing　before。

Happiness　and　self…esteem　are　closely　related。　Laughter　will　help　you　build　your　self…confidence　at　any　given　moment　because　you　know　that　you　can　laugh　rather　than　cry　at　daily　frustrations。

Laughter　is　good　general　physical　exercise。　It　exercises　the　heart；　improves　circulation；　and　gets　rid　of　excess　air　in　the　lungs。　Recent　studies　have　shown　that　a　good　laugh　provides　a　mini…workout　for　the　body　that　actually　burns　up　calories3。

Both　teachers　and　students　experience　a　great　deal　of　stress
