The idea is to encourage family and friends to hug more often. Whether you cuddle a stranger or a family member the mental health benefits are said to be positive. So if you see our reporter Tiffany out and about Hastings today, feel free to give her a good squeeze.
Come back later for more hugs and cuddles.
