Summer Health Preservation: Four Common Mistakes to Avoid
Drinking More Beer Can Beat the Heat
On hot summer days, drinking beer can indeed feel refreshing. However, excessive consumption can lead to a dry mouth, a sore throat, and a general feeling of body heat. This is because beer contains alcohol. Consuming too much at once leads to a high concentration of alcohol in the body. If one continues to drink beer, the "warming" sensation caused by alcohol persists, worsening symptoms like thirst and sweating.
The Earlier the Morning Exercise, the Better
Many people believe that the earlier they exercise in the summer, the better. In fact, the air is not fresh before dawn or when the sky is just beginning to lighten, making it unsuitable for exercise. According to expert research, before 6 a.m. in the summer, air pollutants are least likely to disperse, reaching peak pollution levels. Furthermore, before sunrise, without photosynthesis, there is little fresh oxygen around green plants. Exercising too early can make one susceptible to colds and trigger conditions like joint pain and stomachaches. Therefore, summer morning exercise should not start before 6 a.m.
Air Conditioners Should Maintain a Constant Temperature
Many people are in the habit of setting their air conditioner to a fixed temperature during the summer. In reality, constantly adjusting the indoor temperature can keep the body's thermoregulatory mechanism in a state of "alert," thereby improving one's adaptability and self-protection and reducing the likelihood of catching colds or other indoor-related illnesses. Of course, when first using an air conditioner for regulation, the temperature variation should be controlled between 3°C and 5°C. After half a month, the range can be gradually increased to 6°C to 10°C. Temperature changes should also not be too abrupt; it is advisable to adjust by 1°C to 2°C at a time.
The Darker the Sunglasses, the Better They Protect the Eyes
Many believe that the darker the sunglasses, the better they protect the eyes. This view is incorrect. If the lens color is too dark, it can significantly reduce visibility and cause eye damage. Experts recommend choosing sunglasses that allow 15% to 30% of visible light to pass through, with gray and green being the best choices.
