Most people think thick blood is a problem exclusive to the elderly, but with changing lifestyles, this problem is increasingly affecting younger people. Clinically, thick blood is no small matter. It’s like the gradual accumulation of silt in a river, affecting blood circulation and increasing the risk of cardiovascular and cerebrovascular diseases.
During sleep, the body often quietly sends out signals that the blood may be thickening. For example, if you experience the following four symptoms while sleeping, they may indicate thickening of the blood.
1. Dizziness and loss of consciousness in the morning
After a night’s sleep, you should normally feel refreshed and clear-headed when you wake up in the morning. However, if you frequently feel dizzy and groggy, or even shrouded in a fog, you might be concerned about high blood viscosity.
During sleep, blood circulation is relatively slow. Excessive blood viscosity can lead to insufficient blood supply to the brain, which in turn affects brain function. Furthermore, with physical activity, blood circulation gradually increases, so this dizziness may gradually subside in the morning. However, if it persists for a long time, it’s important to pay attention and have your blood checked promptly.
2. Uncontrollable drowsiness after lunch
Many people experience drowsiness after lunch, but this usually resolves after a short rest. For those with high blood viscosity, this uncontrollable drowsiness after lunch can even affect their afternoon work and daily life. This is primarily because after eating, the digestive system kicks into action, and blood concentrates in the gastrointestinal tract to aid digestion. During this time, blood viscosity can lead to insufficient blood supply to other parts of the body, and the brain, deprived of blood and oxygen, can cause particularly intense drowsiness.
