Happy holidays! Show the people you love that you care today. Because Science, that’s why!

1. Smiling – even if you have to fake it to start – has been shown to actually make you happier, even if you start out grumpy.

2. Hugging and Cuddling release oxytocin and make you feel amazing.

3. Kissing leads to spikes of dopamine – the “holy crap this is awesome!’ neurotransmitter – leading to those feelings of love and elation that are so awesome.
