When we touch – cuddle, hug, or holding hands – our bodies release “feel good” hormones. These hormones include oxytocin, dopamine, and serotonin. Once the hormones are released into our bodies we experience feelings of happiness, relaxation, improve mood, and lower levels of depression.
Cuddling boosts oxytocin levels in your brain. According to Psychology Today, oxytocin is an essential hormone that does everything from making you feel good to helping you feel connected with others. Building an internal connection with your loved ones is just one of the many key benefits of cuddling. Cuddling reduces social anxiety. Again, Oxytocin inspires positive thinking and aids in having an optimistic outlook on the world.
