National Cuddle Up Day is January 6th. January is typically some of the coldest days of the year, so what better way to stay warm and reap the health benefits of cuddling? Whether it’s a night so cold or only slightly chilly, there are multiple benefits to cuddling with human or canine pet. Cuddling releases oxytocin; this hormone has tremendous health benefits. Besides giving us warm & fuzzy feelings, oxytocin reduces pain. When the cold has made those muscle & joints ache, cuddling can help reduce pain.
