9 . Summer is the swimming season. As fun as a swimming pool can be, it’s also a major safety risk if you don’t take the proper measures. Here are some tips for a safe swimming season.
Have supervisors (监护人) to watch over the safety.
Keep a variety of floating devices in and around the pool like a life jacket plus pool noodles or a paddle board. That helps when accidents happen.
Supervisors should also learn basic CPR. It only takes three steps, which is easy to learn. However, it saves life in the “golden four minutes” right after accidents happen.
Another risk is a condition called “dry drowning”. This happens after a near-drowning event in which water gets into someone’s lungs.
A.Drowning can happen in an instant |
B.Drowning isn’t the only danger with pools |
C.Pool owners should be sure to have a fence around their pool |
D.When someone is drowning, they should call for help as quickly as possible |
E.A drowning person having something to grab can get out of the pool quickly |
F.That means the airway is closed off and can’t provide someone with enough oxygen |
G.If children or inexperienced swimmers are in the pool, it’s very important to have close supervision |
10 . Consumption of ultra-processed foods (UPFs) has increased over the past 20 years. UPFs contain few or no whole foods, are industrially produced, are ready-to-eat or ready-to-heat, and include additives. The ultra-processing of food lessens its nutritional value. It has been known that higher UPF consumption is associated with overweight and heart disease. Now, research has been extended to examine its impact on mental health.
In a new study, over 72,000 participants who were at least 55 years old and didn’t have dementia (痴呆) at the start of the study were followed for an average of 10 years, during which they filled out questionnaires regarding their diet. By the end of the study, 518 people were diagnosed (诊断) with dementia. After adjusting for other factors that could affect risk of dementia such as age, gender, and heart disease, researchers found every 10 percent increase in daily intake of UPFs was associated with a 25percent higher risk of dementia. They also found replacing 10 percent of UPFs with unprocessed or minimally processed foods was associated with a 19 percent lower risk of dementia.
In another study, researchers found individuals who consumed the most UPFs had statistically significant increases in the symptoms (症状) of mild depression, “mentally unhealthy days”, and “anxious days”. Eric Hecht, Founder and Executive Director of the Institute of Etiological Research, said, “More than 70 percent of packaged foods in the US are classified as UPFs and represent about 60 percent of all calories consumed by Americans. Given the degree of exposure to and effects of UPF consumption, this study has great significance in clinical practice and public health. It might help improve future development of dietary guidelines.”
Facing such alarming data, maybe it’s time for Americans to reconsider their food options. Researchers recommend taxes on UPFs and carrying out policies to reduce the consumption. They also support programs and policies to increase the availability and affordability of whole foods, especially among disadvantaged populations.
