Actress Shilpa Shetty feels laughing heartily has become a privilege in our fastpaced lives, and has asked people not to forget to take out time and find reasons to laugh."Ever wondered why a carefree laughing session with your friends feels so good? A good, hearty laugh boosts the immune system and relieves physical & mental stress, leaving your muscles relaxed for up to 45 minutes thereafter," she wrote on Instagram along with an image of herself laughing out loud."Laughing freely and heartily has become a privilege in our fast-paced lives. So, if meeting up with friends and/or family is a challenge in these times, watch a funny movie/video or read some comedic literature, instead... because laughter truly is the best medicine," she added.The actress shared the post using hashtags: #ShilpaKaMantra #SwasthRahoMastRaho #mentalhealth #goodhealth #stayhappy #Laugh #LaughterIsTheBestMedicine #behappy.Shilpa is all set to return to the screen after 13 years with two releases, "Hungama 2" and "Nikamma".Directed by Sabbir Khan, the action-packed romantic comedy film "Nikamma" also features Abhimanyu Dasani and Shirley Setia. "Hungama 2" also stars Paresh Rawal, Pranitha Subhash and Meezan. The film is a follow-up of Priyadarshan's 2003 slapstick hit, "Hungama".
