The clear and warm weather in Folsom is expected to encourage outdoor participation in events like the International Yoga Day celebration. However, prolonged exposure to the sun during the longest day of the year could increase the risk of dehydration and sunburn for those spending extended periods outdoors. Participants are advised to stay hydrated and use sunscreen to mitigate these risks. The event is free and open to the public, providing a safe and welcoming environment for community engagement.
