The video features Dr. Bipin Jose, a consultant pulmonologist and specialist in pediatric respirology, who explains how to properly apply oil to the body to prevent allergies and respiratory issues. He advises against applying oil to the hair and scalp for long periods, as it can cause excessive sweating and attract allergens, which can be inhaled and worsen respiratory infections. Instead, he recommends applying oil to the hair for about half an hour before washing it off. He also suggests applying a thin layer of oil to the rest of the body, excluding the head, to keep the skin hydrated and prevent skin diseases and fungal infections. Additionally, he emphasizes the importance of drinking at least three liters of water daily for a healthy person, but advises those with kidney, heart, or liver problems to follow their doctor’s recommendations. He concludes by mentioning that allergies can be managed with modern medicine and encourages viewers to seek professional help.
