These 10 dietary habits are stealing your lifespan

In spring, all things give birth and the functions of the human body also undergo changes. Due to an increase in overall oxygen demand and dilation of cerebral blood vessels, the body is prone to feelings of drowsiness and fatigue. However, it is worth noting that the early symptoms of many diseases are similar to "spring fatigue". When the body sends out the following signals, it may not be an ordinary "spring fatigue", and it is necessary to be alert that this is the body issuing an "alarm".

Spring drowsiness is a normal physiological phenomenon, but some "drowsiness" may not be true drowsiness and may hide health crises. Physiological spring fatigue usually occurs during the transition of seasons. As the temperature rises, blood vessels in the human body dilate, blood pressure decreases, and blood supply to the brain relatively decreases. In addition, the secretion pattern of melatonin is disrupted, and metabolism accelerates, which can easily lead to fatigue and drowsiness. This kind of "drowsiness" is regular, for example, it will worsen in the afternoon and can be significantly relieved after rest or exercise. It usually lasts for a few weeks and will disappear on its own.

Pathological drowsiness is completely different. It often persists and cannot be relieved no matter how much rest is given, accompanied by other discomfort symptoms. For example, patients with hypothyroidism may experience symptoms such as weight gain, sensitivity to cold, and dry skin in addition to drowsiness; Anemic patients often experience fatigue accompanied by pale complexion, dizziness, and blurred vision; The early sleepiness of diabetes patients may be accompanied by polydipsia, polydipsia and polyuria.

Qian Jian, Deputy Chief Physician of the General Medicine Department at Nanjing Gulou Hospital, introduced that the key to distinguishing between "true drowsiness" and "false drowsiness" in the first place lies in three points: first, whether the symptoms persist and cannot be improved through rest; Secondly, whether it is accompanied by other physical abnormalities; The third is whether there are high-risk factors for specific diseases (such as family history, unhealthy lifestyle habits, etc.). Once signs of "false spring fatigue" are detected, it is recommended to seek medical attention and investigate in a timely manner.
