On a summer afternoon, the sun shines through the curtains and casts dappled light and shadows, making the house cool and pleasant. On this hot dog day, Li Liying, who lives in the center of the city, sat at her desk and concentrated on reading a magazine about health. She is a retired teacher who lives a disciplined life, likes to dance aerobics in the gym, and usually cooks some nutritious home-cooked food. However, in recent days, her mind has been a little foggy, and she occasionally has a vague memory, which makes her feel a little worried.
Li Liying thought to herself that maybe the weather has been too hot lately, and she may not have noticed some health details, resulting in a decline in brain function. She decided to look up some information about summer health to see if there was any inspiration. So, she turned on her phone and started searching for content about "dog day health effects."
Dog days and their health effects
The dog days, i.e., the "first volt", "middle volt" and "last volt", are specific periods of time in the traditional Chinese solar terms, usually from mid-July to mid-August each year. During this period, the temperature is high, the humidity is high, and the sun is strong, which can easily cause the maladaptation of human body functions and health problems.
Climatic characteristics and their impact on the human body
During the dog days, the temperature is as high as 30 degrees Celsius or more, and in some areas it can reach 40 degrees Celsius. Such climatic conditions not only have an impact on the cardiovascular system, but also have a negative impact on brain function and the nervous system.
Brain injury risk and prevention
In such a high-temperature environment, the human body is prone to a decline in brain function due to poor thermoregulation. Long-term exposure to high temperatures can increase the burden on the brain, easily causing symptoms such as dizziness, headaches, and lack of concentration, and even serious consequences such as heatstroke.
In order to prevent brain damage, Li Liying learned some coping strategies after studying some relevant materials. First of all, she learned to control her physical activity in hot weather, especially at noon. Secondly, she began to pay attention to adjusting her eating habits, eating more light and easily digestible foods, and avoiding foods that are too greasy or spicy. In addition, she has strengthened her use of indoor air conditioning to keep the indoor environment comfortable.
Overall, the health effects of dog days cannot be ignored, especially for middle-aged and older people. By learning and adjusting her living habits, Li Liying hopes to stay healthy this summer, stay away from bad influences, and enjoy a cool and pleasant summer.
The effects of excessive outdoor activity on the brain
During dog days, many people enjoy getting outdoors and participating in various activities, however, prolonged exposure to high temperatures is not good for health, especially for the brain. Studies have shown that overexposure to sunlight can lead to problems such as dehydration, heat stroke, etc., all of which can affect brain function. In a high-temperature environment, in order to maintain a stable body temperature, the human body will dissipate heat through perspiration, and if it cannot replenish water in time, dehydration may occur, which will lead to an increase in blood viscosity and affect the blood supply to the brain. This can affect the normal metabolism and function of brain cells, and even lead to cerebral ischemia and hypoxia, increasing the risk of brain damage.
In response to this problem, it is recommended to reduce prolonged outdoor activities in hot weather, especially during hot afternoon hours. Choose early morning or late afternoon activities to avoid prolonged exposure to the sun. At the same time, it is important to take good sun protection by using the right sunscreen, wearing a hat, sunglasses, etc., to reduce the negative impact on your skin and overall health.
The relationship between irrational eating habits and brain health
Diet is especially important during dog days, and unreasonable eating habits will not only affect your health, but also directly affect the normal functioning of your brain. In hot weather, people often like to eat cold drinks and cold food to relieve the heat and cool down, but excessive cold drinks and raw and cold food are easy to hurt the spleen and stomach, affect digestion and absorption function, and thus affect the nutrient supply to the brain. In addition, eating excessively salty or overly sweet foods can easily lead to changes in the concentration of electrolytes and sugars in the blood, which in turn affects the normal metabolism and signaling of brain cells, increasing the risk of brain damage.
Therefore, it is recommended to maintain a balanced and varied diet during the dog days, and consume more foods rich in brain nutrients, such as fresh fruits, vegetables, whole grains, etc. At the same time, drinking warm water in moderation and avoiding too many cold drinks and overly irritating foods can help maintain blood stability and normal brain function.
