Smiling can trick your brain into happiness — and boost your health

Ever had someone tell you to cheer up and smile? It’s probably not the most welcomed advice, especially when you’re feeling sick, tired or just plain down in the dumps. But there’s actually good reason to turn that frown upside down, corny as it sounds. Science has shown that the mere act of smiling can lift your mood, lower stress, boost your immune system and possibly even prolong your life.
It’s a pretty backwards idea, isn’t it? Happiness is what makes us smile; how can the reverse also be true? The fact is, as Dr. Isha Gupta a neurologist from IGEA Brain and Spine explains, a smile spurs a chemical reaction in the brain, releasing certain hormones including dopamine and serotonin. “Dopamine increases our feelings of happiness. Serotonin release is associated with reduced stress. Low levels of serotonin are associated with depression and aggression,” says Dr. Gupta. “Low levels of dopamine are also associated with depression.”
Fake It Till You Make It
In other words, smiling can trick your brain into believing you’re happy which can then spur actual feelings of happiness. But it doesn’t end there. Dr. Murray Grossan, an ENT-otolaryngologist in Los Angeles points to the science of psychoneuroimmunology (the study of how the brain is connected to the immune system), asserting that it has been shown “over and over again” that depression weakens your immune system, while happiness on the other hand has been shown to boost our body’s resistance.
“What’s crazy is that just the physical act of smiling can make a difference in building your immunity,” says Dr. Grossan. “When you smile, the brain sees the muscle [activity] and assumes that humor is happening.”
In a sense, the brain is a sucker for a grin. It doesn’t bother to sort out whether you’re smiling because you’re genuinely joyous, or because you’re just pretending.
“Even forcing a fake smile can legitimately reduce stress and lower your heart rate,” adds Dr. Sivan Finkel, a cosmetic dentist at NYC’s The Dental Parlour. “A study performed by a group at the University of Cardiff in Wales found that people who could not frown due to botox injections were happier on average than those who could frown.”
And there are plenty more studies out there to make you smile (or at least, serve as reference for why you should). Researchers at the University of Kansas published findings that smiling helps reduce the body’s response to stress and lower heart rate in tense situations; another study linked smiling to lower blood pressure, while yet another suggests that smiling leads to longevity.

Lin Ching-yi calls for restricting power in Taiwan after 10 p.m. to save energy, raise birthrate

DPP legislator Lin Ching-yi suggests restricting electricity after 10 p.m. will save energy and raise the birthrate
TAIPEI (Taiwan News) -- The Democratic Progressive Party (DPP) Legislator Lin Ching-yi (林靜儀), yesterday evening (May 2) suggested that power be restricted after 10 p.m. to help conserve energy and resolve the country's low birthrate.
The Facebook page called Citizens Miaokou (公民廟口-立委在做天在看) posted a video at 6:56 p.m. last night of a question and answer session in Taiwanese dialect and Mandarin with Lin and Environmental Protection Administration (EPA) chief Lee Ying-yuan (李應元). During the session, Lin suggested that power be limited after 10 p.m., people should go home from work, not to turn on the TV and lights and everyone should go to sleep early.
Lin reasoned that taking these steps would solve the energy problem and would also "solve the problem of fewer children." Laughing, probably at the latter comment about increasing the birthrate, Lee concurred with her suggestions.
Lin said that this would would lead to a more healthy lifestyle, with better sleep and the ability to wake up at 5 a.m. In response, Lee said, "I completely agree, lifestyle changes will conserve energy."
She went on to say that she asked that cable TV stations not play movies late at night, "otherwise everyone won't sleep at night as they watch reruns of movies, it's actually a waste of resources. Those old movies have been replayed hundreds of times."
Netizens reacted to her simplistic suggestions with sarcastic remarks:
"This is great, Lin Ching-yi is very wise brilliant and the workers are overwhelmed with gratitude. From this day forward, laborers will never have to be overworked again!"
"This is great, only she could thing of such a ingenious idea, everyone was drunk and you woke them up. Global warming has been solved. This is deserving of many Nobel Prizes."
