I have a severe cold with running nose.
Do LINGA Mudra (both hands clasped together, with left thumb in upright position) for 20 minutes. Then do SAFE and SECURE Mudra (thumb touching ring and little fingers on both the hands) for another 20 minutes.
I did as you suggested. I took rest for a while keeping in mind that while we sleep, our body does the necessary healing (as mentioned by Naran).
After waking up, I did the Mudras again for 15 minutes. I was alright (without any medication). Thanks.
Due to pollution, we get afflicted with cold.
The thick phlegm produced and deposited inside the lungs will be converted into liquid form by the Linga Mudra and will be sent to the Hara Chakra (the chakra that handles water element) by the Safe and Secure Mudra.
