Kate says 'nature has been my sanctuary' in new video

The Princess of Wales has again turned film narrator to highlight the important part she believes nature can have for maintaining our mental health.

A video was released on the Kensington Palace social media channels at lunchtime, entitled Mother Nature. A palace spokesperson confirmed it will be one of four videos released to coincide with the seasons, with the first reflecting spring and released to mark the start of Mental Health Awareness week.

They said the videos are designed to show "nature's capacity to inspire us and help us to heal and grow in mind, body and spirit". In the short video, Kate and Prince William are filmed walking through the countryside on the Isle of Mull, where they recently spent their 14th wedding anniversary, while on a two-day official trip to the remote Scottish island.

Some of the video shows other places of natural beauty across the UK, but the palace wouldn't confirm where they were all filmed. In her narration, the princess says: "Over the past year, nature has been my sanctuary… It is through nature, that we can fully understand the true interconnectedness of all things, the importance of balance and the importance of renewal and resilience.

Connecting to nature helps us to experience a deeper sense of ourselves, the world around us, and each other". Talking specifically about this season, she adds: "Spring is a season of rebirth, of hope and new beginnings.

"From the dark days of winter, the outside world quietly awakens with new life, and there comes a sense of optimism, anticipation, and positive, hopeful change." It comes after the couple released a video last September, of them and their children playing in the woods and on the beach in Norfolk, to announce the princess had completed her cancer treatment. Ever since her diagnosis, Kate has regularly spoken about what she believes is the healing power of spending time in nature.

It resonates with her wider work around mental health and encouraging children and families to spend more time outdoors.

"As we confront the challenges of an increasingly complex and digital world, the importance of the connection between humanity and nature takes on even more significance," she writes. Kate's interest also reflects a wider family appreciation of nature from the King and Prince William's high-profile campaigning on the environment, to Meghan's recent social media posts talking about the joy she gets from spending time in her garden in Montecito, California..
