Summer often goes hand in hand with prolonged, high-intensity heat waves, clearly affecting human health. Not only creating a feeling of stuffiness, extreme weather also increases the risk of contracting or exacerbating many diseases.
According to Dr. Tushar Tayal, Deputy Director of Internal Medicine at CK Birla Hospital (India), summer is a period when many lifestyle-related diseases such as diabetes, high blood pressure, obesity and cardiovascular disease tend to become more severe, because the body is prone to dehydration, metabolic disorders and greater pressure from ambient temperatures.
Hot weather can affect blood sugar
Dr. Tushar Tayal said that high temperatures can change blood circulation, thereby affecting insulin absorption rates in people with diabetes. This makes blood sugar control more difficult on hot days.
In addition, insulin can also reduce its effectiveness if stored improperly in a high-temperature environment. In addition, hot weather also increases the body's secretion of cortisol, a stress-related hormone that can cause blood sugar levels to rise.
Even in people who have not had diabetes, prolonged heat stress can also increase the risk of insulin resistance if it occurs for a long time.
Dehydration increases pressure on the heart and kidneys
In the summer, the body has to work harder to regulate temperature. When it's hot, more blood is delivered to the skin surface to cool the body, causing the heart to pump blood continuously with higher intensity.
This can put great pressure on people with cardiovascular disease or high blood pressure. People with underlying conditions but not yet detected may also face a higher health risk in hot weather.
Dehydration is also a common problem in the summer. When the body sweats a lot but does not supplement enough water, the blood may become more concentrated, causing difficulties for circulation and blood pressure regulation.
According to doctors, this condition also causes the kidneys to work harder to retain water and filter blood. This is also the reason why the number of kidney stones, urinary tract infections and kidney damage often increases in hot months.
Lifestyle changes in the summer
High temperatures in summer can affect daily living habits. Hot weather makes many people reluctant to exercise, limit going out, thereby reducing physical activity.
In addition, sleep is also easily affected. Many people have difficulty sleeping deeply or often wake up due to hot weather. Prolonged sleep deprivation can increase appetite, affect blood sugar control and increase the risk of cardiovascular disease.
Doctors recommend that people drink enough water, maintain a reasonable diet, exercise appropriately and get enough sleep in the summer to protect their health.
