God said: Proverbs 15:13, 15:15, 17:22, Ecclesiastes 8:15, 9:7-9.
The Bible says:
A merry heart will do me good like a medicine/A merry heart puts a smile on my face and the smile will make my heart merrier (not to mention making other people’s hearts merrier)/ If my heart is merry , I will find that life is like having a continual feast/I will enjoy my food and drink and it is to be commended because I can keep the benefits of happiness but all the other results of hard work will pass./ So what’s a man to do? Work hard for the Lord and don’t fret about, “Did I do it well enough to please God?” He accepts even my feeble , imperfect efforts. Eat, drink, be merry, put on clean clothes, comb my hair, live joyfully all my life with the wife I love, and whatever I find to do, do with all my might.
Human research has found that the Bible is correct:
Infrequent laughter was associated with long-term blood pressure increase among middle-aged men.
Laughter therapy is considered to be useful, cost-effective and easily accessible intervention that has positive effects on depression, insomnia, and sleep quality in the elderly.
Results indicate that serotonin activation through laughter therapy can help middle-aged women by lessening depression and providing important grounds for depression control.
A meta-analysis revealed that laughter and humor interventions are effective in relieving depression, anxiety, and improve sleep quality in adults.
A daily frequency of laughter is associated with lower prevalence of cardiovascular diseases.
There are lower depression scales in people treated with laughter therapy.
It was noted that depression reduces the frequency of laughter and, inversely, laughter reduces the severity of depression.
Laughter also increases the connectivity of patients with people in their life, which further alleviates symptoms of depression
Laughter lowered the after meal peak glucose level in 34 patients with diabetes.
People with heart disease respond less humorously to everyday life situations.” They generally laugh less, even in positive situations, and displayed more anger and hostility.
Hearty laughter leads to pain relief, probably through the release of endorphins.
The pain threshold is significantly higher after laughter than in the control condition. This pain-tolerance effect is caused by the laughter itself.
When 52 healthy men watched a funny video for 30 minutes, they had significantly higher activity of natural killer (NK) cells and higher levels of IgG, IgA, and IgM (all of which helps the immune system defend us and eliminate cancer as it arises) compared with men who watched an emotionally neutral documentary.
Humor, as measured by the Sense of Humor Survey showed that the higher the sense of humor score, the higher the odds ratio of surviving 7 years.
It has been demonstrated that laughter is able to improve mood directly and to moderate negative consequences of stressful events on psychological well-being; in addition, it is possible that the stimulation of particular cerebral regions, involved in depression pathogenesis, and the normalization of the hypothalamic pituitary adrenocortical system dysfunctions, both mediated by laughter, can efficiently counteract depressive symptoms.
My own experience:
When I feel overwhelmed at work, I take out the complete collection of Calvin and Hobbes that Lois bought me and I read and laugh and find what I need to get back to life.
When a situation is especially tense, I find that helping the other person laugh is key to making progress. I never laugh at anyone but rather laugh with them at the mutual craziness of human nature and life in general.
I love the picture of Jesus laughing and think that we all need to lighten up, after all we are already victors and it is all pretty crazy at times.
