The Beginning of Summer is the first solar term in summer. It begins the hot summer days in the northern hemisphere when crops are thriving.
As the temperature in the south of the Yangtze River rises rapidly, the rainfall increases significantly during this period.
Traditional Chinese medicine believes that summer belongs to fire in the five elements and corresponds to the "heart" in the five organs of the human body.
In summer, heart Yang is exuberant, but the hot and sweaty weather tends to consume Heart Qi. Therefore, people should protect Yang and nourish the heart at this time.
The exercise of Beginning of Summer strengthens the pericardium meridian sinew of hand-Jueyin.
It starts from the middle finger, connects to the inner side of the elbow, extends to the armpit along the inside of the upper arm, and spreads down to the front and back of the flank.
When you breathe in, raise your legs. Cross your fingers and hold your knee. Then, lean your body back to stretch.
When you breathe out, drop your legs, release your fingers, and retract your hands to the waist.
Repeat several times according to your own conditions.
The days are long and the nights are short in summer, so sleep time may not be enough. You can take a nap to keep energetic.
