Why do we stretch in the morning? So that we can sleep for two more hours. No. Wait. I will explain. When we wake up in the morning, we yawn and stretch our arms and legs. This coordinated yawning and stretching is referred to as pandiculation. I thought it is referred to as calculation. Just listen. When we are asleep, we don’t perform any activities. Hence, our heart rate becomes slow and the blood flow is decreased. Also, as many people lie in the same position for long hours, their muscles become stiff and tight. Thus, a good stretch in the morning awakens our body. It brings our heart rate back to normal, improving the blood flow to various body parts. Stretching also loosens and realigns our stiff muscles, making them more flexible and ready for the day ahead.
