Chris Hemsworth isn't waiting for ragnarok to make his health a priority. Since the Thor actor learned he has an increased risk of developing Alzheimer, he's implemented a variety of lifestyle changes that are supposed to benefit not only his overall health. "I'm incorporating more solitude into my life," Chris told Men's Health in an interview. "I've always been pretty consistent with my exercise commitments, but lately I've really felt the importance of taking time for yourself without any outside voice or stimulation and making time for stillness." And part of that stillness involves a focus on mindfulness. "I do a lot of meditation mostly during sauna and ice bath routines," the 40-year-old explained. "For me, my favourite mindfulness work comes from the immersion in physical actives that allow me to be fully present and force me out of me head and into my body, in particular surfing." Another key component of his routine? Prioritising sleep and exercise. Chris first learned of his pre-disposition for Alzheimer's while undergoing genetic testing for his National Geographic docuseries Limitless.
