Step Out In The Sun
Stepping out in the natural light is one of the major contributors to the production of Vitamin D in our body. Vitamin D is essential for healthy functioning of the immune system as it helps the body to produce antibodies. Low level of Vitamin D in the body has been termed as one of the major reasons for respiratory problems. A brisk walk in the sunlight for 10–15 minutes will ensure that enough Vitamin D is produced in the body.
