Yes! it is the "Udgeeth Pranayam".
This pranayam is very easy, anybody can learn and practice.
Method: Sit in any position with back straight. Inhale deeply and exhale slowly with the sound of O.........m. The exhalation takes 15 seconds(10 seconds for long OOOOOOOO and 5 seconds for small mmmm). This is one round. Practice 3 to 10 times daily and see the amazing results!
p.s. For the first time this technique can be learnt under the supervision of a yoga teacher/guru.

Stay fit and healthy always. Daily practice asanas and pranayam that suit your time and energy. Ex. Few rounds of Suryanamaskar will keep you fully charged till the next day.

Prevent diseases. Practice important asanas, pranayam or kriyas daily. Ex. Doing jal-neti or Udgeeth pranayam will keep cough, cold, acidity at bay, clearing the respiratory pathway and bringing immunity in the changing seasons.

Do not eat too hot food

Many people are fond of eating very hot food-- piping hot soups, chilli paneer, sizzlers etc..etc...Occasionally very hot food can be eaten but it should not be made a habit. Regularly eating too hot foods may lead to the following problems :

* Mouth: Eating too hot food is harmful for the teeth and their roots. It may also cause Micoza, the cavity in the mouth.
* Stomach: There is a possibility of more flow of acids in the stomach leading to acidity. Gastric ulcers may be formed in the stomach (those who eat hot food are also fond of spicy food).
* Intestines: Eating hot food over a long period of time may affect the flow of digestive juices causing ulcer in the intestines too. As a result a person may suffer from digestion related troubles like gastric and constipation.The membrane of the intestines may also get damaged.
The temperature of the food should be moderate-neither very hot nor very cold. Enjoy your food keeping good health in mind.
