Human beings have an immense capacity to adapt and thrive under the most difficult of weather conditions. The innovation of the human mind, the will power of the human spirit and the adaptability of the human body have enabled us to survive in the merciless heat of the Sahara desert, the freezing conditions of the Arctic and the unpredictable rains of the tropics. In modern times, our dependence on air conditioners, coolers or heaters has reduced our will power and disconnected us from our powerful abilities to adapt to nature.
Yoga views the human mind-body complex as an intelligent system that is equipped to deal with the stimuli of the surroundings. This is the reason that ancient yogis were able to adapt to the freezing temperatures of the Himalayas where they lived, studied and meditated. So, the reverse is also applicable to those of us who are on the verge of enduring the intense summer heat. Yoga sees the body as divided into the sun half (right side) and the moon half (left side). Breathing exclusively through the left nostril is said to draw upon the self-cooling abilities of the body. This stimulates the parasympathetic nervous system, which then encourages the removal of excessive bile from the body. This, in turn, boosts lymph drainage and removes built-up heat from the organ systems and the blood. Regular practice of the following pranayama also helps cool down the breath and the brain.
Simple Chandra Bedhana Pranayama (Channelling the Moon Energy)
Note: This breathing exercise can be done at any point of time during the summer. Avoid this during winter and if you have a fever, infected sinuses or a cold.
Sit comfortably with your back supported against the wall or the back of a chair. Sitting on the ground is also a good option.
Keep your chest open and the back straight. Bring your chin parallel to the ground.
Fold the index and middle fingers of your right hand to the base of your right thumb. Use the thumb to close the right nostril. Place your ring finger at the centre of your forehead.
Breathe in through your left nostril, hold your breath for two counts and exhale through your left nostril.
Repeat 20 times.
