"I love you" raises body temperature. Video "LOVE THERMO #WarmWithILoveYou" surpasses 1.8 million views in one week.

Panasonic's web video "LOVE THERMO #WarmWithLove," featuring its "Everyday Premium Series" air conditioner, has garnered over 1.8 million views in about a week since its January 21 release, generating significant buzz.

The video explores the theme "Love warms people," focusing on how "words of love" from family members affect a person's "body temperature." It measured changes in body temperature (surface temperature around the nose) before and after participants received verbal expressions of gratitude or love, using a thermopile infrared sensor.

For the experiment, six family pairs—including husbands and wives, mothers and daughters—were gathered at the venue under the guise of a "family interview." One member from each family acted as the instigator, surprising their family member (the subject) during the interview by reading a letter expressing gratitude or love and handing them a gift.

The results showed that the subjects' body temperature rose by an average of 0.8 degrees Celsius. Some individuals even saw a 1.2-degree increase, proving that words of love activate the parasympathetic nervous system, warming not only the heart but also the body.

It's often said that Japanese people struggle to express love. Data shows that 84.7% of people don't verbally say "I love you." The main reasons cited are "it's not a habit," "it's embarrassing," or "they should understand without being told." However, this experiment revealed that even actions once thought meaningless because "they should understand" actually hold significant meaning.

On social media, the video drew comments like: "I started tearing up watching this," "Expressing love is so important," and "This might be the first time I got completely absorbed in an ad." Some even shared they tried it with their wives or husbands. Due to the strong response, it has been featured across numerous media outlets, including television.

Tomoyo Kimura from Panasonic's CMJ Headquarters Communication Department stated, "The view count significantly exceeded our initial goals. It was successful because it was retweeted on social media like Twitter and Facebook, leading to natural sharing and spreading. I think the level of resonance, especially from people in their teens and twenties, was greater than we imagined."
