Common Misconceptions About Health After Autumn Begins
As autumn approaches, many people, especially the elderly, often believe that it is necessary to "nourish" their bodies to combat summer fatigue. This notion, summed up by the saying, "a summer without illness means three parts weakness," can lead to harmful health practices.
Misconception 1: It's Time for Heavy补药 (Supplements)
Many seniors rush to consume various traditional supplements as soon as autumn begins, under the belief that it will cure ailments or enhance their strength. However, this is scientifically unfounded. For individuals suffering from conditions like hypertension or cardiovascular diseases, it is crucial to avoid supplements such as wild ginseng and certain herbs like Eleutherococcus and Aconite, as they may exacerbate their conditions. Instead, focusing on a balanced diet rich in essential nutrients and adopting healthy lifestyle habits is the most effective way to maintain health.
Misconception 2: Lying Down Immediately During Angina Attacks
Imagine an elderly person who suddenly appears pale and sweaty while exercising outdoors, and you suspect they are experiencing angina. In this critical moment, it is vital not to let them lie down. Instead, assist them in squatting or sitting down. Lying flat can increase the workload on the heart and may intensify oxygen deprivation, leading to serious complications like myocardial infarction or even death.
Misconception 3: A Post-Meal Walk Will Ensure Longevity
While light walking after meals can aid digestion, it may not be suitable for everyone. For instance, individuals with coronary heart disease may experience increased heart rate and elevated blood pressure after eating. A sudden post-meal walk can strain an already deprived heart, potentially triggering angina or worse, causing a heart attack. Therefore, for those with hypertension or cardiovascular issues, it's advisable to rest for at least half an hour after eating before engaging in physical activity.
Misconception 4: Wearing Masks for Respiratory Protection
As the weather cools, many elderly individuals wear masks to protect against respiratory infections, believing that cold air harms their lungs. However, it's important to note that the nasal passages and respiratory tract are designed to warm incoming air, thereby minimizing any potential irritation from cold weather. Masks may provide limited protection for the face but are not essential for breathing ease during cold temperatures.
Misconception 5: Morning is the Best Time for Exercise
For those suffering from hypertension and cardiovascular diseases, mornings can be risky for physical activity. Medical studies indicate that the likelihood of a heart attack is three times higher at 9 AM compared to 1 PM. Therefore, engaging in exercise during the early hours may pose more risks than benefits. The ideal times for physical activity for seniors should be after noon and around dusk, aligning with their biological rhythms.
Misconception 6: Seasonal Training Regardless of Weather
Some believe that training hard during winter and summer seasons can increase immunity. While engaging in physical activities during winter can bolster resilience against illness, cold weather can constrict capillaries and elevate blood pressure, posing a greater risk for those with heart conditions. Conversely, summertime sports can also impose significant strain on the heart due to high temperatures. Seniors and individuals with hypertension should always exercise caution and tailor their activities according to their physical limits and environmental conditions.
In conclusion, understanding these misconceptions is crucial for maintaining health, especially for the elderly and those with underlying conditions. Prioritizing safety and awareness will lead to better well-being during the changing seasons.
