Interesting fact:

Amazing things happen when we’re in love! Research has found that when loved-up couples gaze into each other’s eyes for three minutes their heartrate will synchronize! And cuddling can produce hormones that act as natural painkillers. The hormone oxytocin is released which can actually get rid of a headache. So this Valentine’s day – get cuddling! And even looking at a picture of someone you love can make you feel less pain. Holding hands with your partner can also be beneficial – it has been shown to relieve stress.
