It’s probably never going to replace a visit to the gym as a weight-loss strategy. But as we approach another Valentine’s Day, it’s good to remember that kissing your significant other burns a few calories a minute.

That beats a half hour on a treadmill any day of the week.

The pseudo-holiday recognized with schmaltzy cards and heart-shaped candies is healthier than you might realize. That is, if you don’t indulge in too many chocolates.

February 14 is also a poignant reminder of just how detrimental loneliness and a lack of companionship can be to well-being. A life without affection and human interaction can lead to depression, susceptibility to other mood disorders and increased pain. It also suppresses the immune system.

Loneliness raises levels of the stress hormone cortisol, which can contribute to long-term cardiovascular problems.

The American Heart Association reminds us that human touch and affection hike levels of dopamine. This hormone creates the feeling of pleasure and reward in our brains. It makes us happy.

A 2014 study in Psychological Science measured the stress levels of 400 adults and asked them how frequently they got hugs. Then, participants agreed to be exposed to a cold virus. Which group got sick more often? You guessed it: the hug-deprived.

Handholding, kissing, hugging and friendly conversation all make us feel better about ourselves. And that makes us healthier. This is also a good reminder to reach out to friends who might be feeling lonely.

Even if you aren’t someone’s Valentine, your companionship and conversation can go a long way to making them feel better.

And it could just make you feel better about yourself.
