Being unable to wake up in summer is a sign of illness

As the saying goes: The hot summer is a good time for sleeping. When the hot summer comes, many people feel sleepy. Little do people know that if the elderly or people with cardiovascular and cerebrovascular diseases always feel weak and sleepy in the summer, they need to be extra careful, as this may be an alarm signal from the body indicating illness.

1. Heart disease

The brain, as the "headquarters" of the human body, directs and coordinates all activities of the human body at all times. Since the oxygen and nutrients needed by the brain when working are mainly provided by the blood pumped to the brain by the heart (1/5 of the blood ejected by the heart each time it contracts flows to the brain), the normality of brain metabolism is closely related to the contractile function of the heart. Generally speaking, when the heart contraction function of the elderly weakens, their brain will suffer from hypoxia. The neurological manifestation of hypoxia in the elderly's brain is that they often cannot wake up. Therefore, if the elderly often experience symptoms of "not being able to wake up", it means that there may be a problem with the contraction function of their heart, that is, they may have heart disease.

If the cerebral blood vessels of the elderly undergo hardening, atrophy or lipid deposition, the permeability of their blood-brain barrier will be reduced, leading to hypoxia and ischemia in their brain tissue. Over time, the elderly will suffer from cerebrovascular diseases such as cerebral infarction, cerebral atrophy, and cerebral thrombosis. During the onset of the above-mentioned cerebrovascular diseases, ischemia and hypoxia of brain tissue will cause people to always be unable to wake up (including changes in sleep frequency and sleep time). Therefore, if the elderly are always unable to wake up, they should be alert to the occurrence of cerebrovascular diseases.

If the elderly suffer from various chronic diseases such as chronic nephritis, diabetes, chronic liver disease, hypothyroidism, etc., their metabolic rate will gradually decrease, resulting in the inability to smoothly excrete toxic metabolites from the body, which in turn affects the regulatory function of their autonomic nervous system, causing them to experience symptoms such as "not being able to wake up" all day and sweating. At this time, they should go to the hospital in time to see if they have any chronic diseases.
