People who love to laugh have good luck, and life is always sunny

The upward curve of the corners of the mouth may hide the password to open the door to happiness. Those who always put a smile on their face are not only more likely to gain the favor of others, but also their bodies are quietly undergoing wonderful changes. Modern science is uncovering the biological secrets behind 'laughter', which turns out to be a simple action comparable to natural health supplements.

1. Smiling Changes Brain Chemical Factory

1. Dopamine Reward Mechanism Activation

When facial muscles make a smiling gesture, the brain mistakenly believes that something good has happened and immediately releases the pleasure substance dopamine. A study found that intentionally maintaining a smile for 15 minutes can reduce depression scores by 26%.

2. Natural increase in serotonin levels

Like natural antidepressants, regular smiling can promote serotonin secretion. When this neurotransmitter is insufficient, people are prone to anxiety and insomnia.

3. Decreased concentration of stress hormones

When faced with difficult tasks, smiling for 30 seconds will result in a decrease of 18% in cortisol levels compared to frowning. That's why interviewers often have a better impression of smiling applicants.

2. The physical benefits of smiling

1. Reduced risk of cardiovascular accidents

Laughing for 15 minutes a day is equivalent to moderate intensity aerobic exercise, which can improve endothelial function by 45%. Regular laughter therapy for heart disease patients significantly reduces the recurrence rate.

2. Immune system upgrade

When smiling, immunoglobulin A secreted is 23% more than when expressionless, and this antibody is the first line of defense in the respiratory tract. Statistics show that nurses who love to laugh have one-third fewer colds than their colleagues.

3. Improved Pain Tolerance

After watching comedy movies, people's sensitivity to pain decreases by 10-15%. Dentists have found that patients who cooperate with a smile to relax require less anesthesia during tooth extraction.

3. Tips for cultivating the habit of smiling

1. Morning mirror practice

When brushing teeth, grin in front of the mirror for 8 seconds, which can activate the facial nerve circuit. Persisting for 21 days will form a conditioned reflex.

2. Set smile trigger

Set a smiling face image on the phone screensaver, and remind yourself to adjust the expression every time you unlock it. A smiling ornament can be placed next to the office computer.

3. Develop a Humor Reserve

Collect three interesting scenes that can be recalled at any time and replay them in your mind while waiting in line. Research has found that recalling happy past events can also trigger sincere smiles.

4. Smiling Misconceptions to Avoid

1. It's better to not smile than to fake a smile

A fake smile that only uses the muscles of the mouth will consume energy, and a sincere smile requires wrinkles around the corners of the eyes. When you can't remember happy things, why not watch cute pet videos.

2. Moderate intensity

Continuous wild laughter may cause brief hypoxia. It is recommended to use a cyclic pattern of "5-minute smile+1-minute deep breathing". Asthma patients should pay special attention to controlling their intensity.

3. Respect cultural differences

Some serious occasions require managing smiles, such as attending funerals or listening to tragic stories. In high context cultures, inappropriate smiles may be misunderstood.

Next time you encounter something bad, why not try grinning at the air first. Those who are always favored by good luck may have just mastered the magic of smiling earlier. Starting today, let this free health tool work for you, after all, even cells like happy owners.
