4 . I couldn’t sleep at all last night, and my sister believes it was because I ate a bowl of really spicy (辛辣的) food before bedtime. However, I was skeptical about the connection between spicy foods and sleep. Can eating spicy foods before bedtime truly impact one’s sleep quality? Some people believe that eating spicy foods before bedtime can disrupt sleep by increasing body temperature and causing heartburn. It may be worth avoiding spicy foods close to bedtime.
To find out the relation, the researchers in Australia conducted an experiment to investigate the effects of spicy foods on sleep. They provided a group of individuals with delicious late-night meals, alternating (交替) between spicy and mild options. The results revealed that consuming spicy foods led to disrupted sleep patterns, causing participants to take longer to fall asleep and sleep for shorter time. This data supported the belief that there is a correlation between eating spicy foods and experiencing sleep disturbances.
While the exact mechanism(机制)by which spicy foods influence sleep remains unclear, researchers have proposed several possibilities. One is that stomach discomfort resulting from spicy food consumption may affect sleep quality. Additionally, the long digestion (消化) of spicy foods could delay the start of sleep. Furthermore, spicy foods contain something that can raise body temperature, which has been linked to poor sleep in previous studies.
Given these findings, it is advisable to avoid consuming spicy foods before bedtime to promote better sleep. Next time, I will follow my sister’s advice and opt for a milder meal in the evening to ensure a restful night’s sleep.

5 . We’ve had weather forecasts for decades. Forecasting our near-term health is far tougher. Yet knowing early that we may be coming down with the flu could be very helpful. The good news is that wearable technology, such as smartwatches, is beginning to provide such information. The smartwatch-like systems contain sensors that collect data.
Jessilyn Dunn is a biomedical engineer at Duke University in Durham. Her team asked 49 volunteers to wear wristbands before and after they received a cold or flu virus. At least once per second, these wristbands recorded heart rates, body movements skin temperatures and more. After analyzing the data, Dunn’s team found that in nine out of very ten volunteers, there were signs of developing illness at least a day before symptoms (症状) appeared.
The early warning, says Dunn, can head off severe symptoms that otherwise would send some people into hospitals. And knowing you’re sick before you have symptoms can warn you to lie low so you can reduce the chance of spreading your disease.
However, these systems aren’t yet ready for the real world, notes virologist Stacey Schultz-Cherry. “This is exciting but also very preliminary (初步的),” says Schultz-Cherry. “Much more work is needed before this approach can be rolled out on a larger scale.” One challenge is that many infections (感染) have analogous symptoms. Actually, besides viruses, many other things also lead to signs of a cold or the flu. Examples, Schultz-Cherry notes, include food poisoning and seasonal allergies (过敏反应). Likewise, heart rates also respond to things that have nothing to do with infections. Examples include exercise and scary movies.
Researchers expect continued improvement in prediction accuracy (准确性). Future models will show signs of developing illness. And researchers will adjust those models by analyzing how well they predict effects on thousands of people.

6 . How to Improve Your Mental Health
Your mental health is an important aspect of your overall health. No matter what your situation is, you can take steps to improve your mental health.
Take a self-assessment(评估). Everyone has what is known as “emotional intelligence” or EQ. EQ refers to how well you understand your emotions and actions. Figuring out your EQ is important if you want to improve your mental well-being.
Set goals. After you have completed your self-assessment, you can clearly identify the areas you would like to focus on improving. Take time to set some clear and achievable goals. These can be both long term and short term goals. Write down your goals.
Handle your emotions. An important part of improving your mental well-being is learning to admit your emotions.
Learn how to identify and deal with your triggers (诱因) . Everyone has different triggers.
Gather information. Avoid the bad name that mental health issues are somehow not “real” problems. Your mental health is just as important as your physical health. Take some time to learn about the importance of your mental health.
A.Take some time to look at the big picture. |
B.This is when you apply a name to the emotion. |
C.Yours might be certain people, situations, or places. |
D.Research different ways to improve your mental health. |
E.This will help you keep them and make your dream come true. |
F.Sometimes it might feel simple r to set aside an uncomfortable emotion. |
G.You can find online assessment tools to help you figure out your results. |
7 . Wilberforce Tushemereirwe holds up a genetically-modified banana that took millions of dollars and 20 years to make. It contains a large amount of provitamin A, a substance that transforms into vitamin A in the body. This “super banana” was created at Uganda’s National Agricultural Research Laboratories for the noblest of causes: to save the lives of thousands of children who die in Uganda every year from a lack of vitamin A.
Vitamin A shortage remains a serious global public health problem. The World Health Organization estimates that 190 million preschool children suffer from vitamin A shortage today, mostly in sub-Saharan Africa and Southeast Asia. It is the leading cause of preventable blindness in children. It also inhibits children’s growth and weakens their resistance to illnesses so that many die from treatable diseases such as diarrhea and measles. In Uganda, one of the world’s poorest countries, it remains high on the list of health risks, which makes it urgent to find ways to deal with the condition.
The Ugandan government has tried for decades to solve the problem — with limited success. Distribution of vitamin A capsules, for example, worked well in urban areas but failed to reach those most in need in rural areas. Increasing corn and wheat flour and eatable oils with vitamin A proved more effective. But those foods are not consumed in large enough amounts to make a meaningful difference. Bananas, a main staple of the Ugandan diet, seemed to be a better option.
Yet, one problem still remains. Fred Wanyu, a Ugandan tribal leader and linguist, says his ancestors considered the banana “the mother of society”. Farmers worry that a new super banana will distort (扭曲) Ugandan banana culture dramatically. Though he respects the ancestors, Wanyu also believes that if a little piece of banana is added to a sister banana, developing into something better, “I think we will live in a better world.” “That’s what many Ugandans wish for as they struggle their way out of malnutrition and extreme poverty.” “Culture is dynamic,” Wanyu said. “Otherwise, we would continue writing on stones.”

9 . Use food to ease your moods? The time of meals may have an impact on moods, including levels of depression and anxiety, according to researchers at Brigham and Women’s Hospital.
To conduct the study, 19 participants (12 men and 7 women) were arranged to experience a Forced Process in a dark room for four 28-hour “days”. Participants were assigned to one of two meal timing groups: the Daytime and Nighttime Meal Control Group, which had meals according to a 28-hour cycle (resulting in eating both during the night and day, which is typical among night workers), and the Daytime Only Meal Group, which had meals on a 24-hour cycle (resulting in eating only during the day). The team then assessed depression and anxiety like mood levels every hour.
The result showed that meal timing significantly affected the participants’ mood levels. During the simulated (模拟的) night shift (day 4), those in the Daytime and Nighttime Meal Control Group had increased depression and anxiety like mood levels, compared to the baseline(day 1). In contrast, there were no changes in mood in the Daytime Only Meal Group. Participants with a greater degree of circadian(昼夜节律的) disorder experienced more depression and anxiety like moods.
Researchers discovered that among individuals in the daytime and nighttime eating groups, anxiety and depression rose by 16% and 26% individually. A famous author Sarah Chellappa, who completed work on this project, said, “Meal timing is emerging as an important aspect of nutrition that may influence physical health, but the causal role of the timing of food intake in affecting mental health remains to be tested. Future studies are required to establish if changes in meal timing can lead individuals to experience anxiety-related disorders.”
The findings open the door for studying a behavioral strategy that might benefit individuals suffering from mental health disorders, such as shift workers. The study also adds to a growing body of evidence finding that strategies that improve sleep and circadian patterns may help promote mental health.

10 . The old saying that “laughter is the best medicine” may contain an element of truth when it comes to heart health. A research has demonstrated that laughing causes the tissue inside the heart to expand and increases oxygen flow around the body.
“Our study found that laughter treatment increased the functional capacity of the cardiovascular (心血管的) system, and patients with heart disease who engaged in a course of laughter treatment had reduced inflammation (炎症) and better health.” said the lead author, Prof Marco Safffi, of the Hospital de Clinicas de Porto Alegre in Brazil.
In the trial, scientists carried out a first-of-its-kind study to examine if laughter treatment could improve symptoms of patients with heart disease. It involved 26 adults with an average age of 64, all diagnosed with the heart disease caused by plaque (斑块) buildup in the walls of the arteries (动脉) that supply blood to the heart. Over three months, half were asked to watch two different hour-long comedy programmes each week, including funny popular sitcoms. The other half watched two different serious documentaries, about heavy topics such as politics or the Amazon rainforest.
At the end of the 12-week study period, the comedy group improved by 10% in a test measuring how much oxygen their heart could pump around the body. The group also improved in a second measure that tested how well arteries can expand. They also had a blood test to measure several inflammatory markers, which indicate how much plaque has built up in the blood vessels and whether people are at risk of heart attack or stroke. The results showed that their inflammatory markers had significantly reduced compared with the documentary group.
“When patients with heart disease arrive at hospital, they usually have a lot of inflammatory markers.” said Saffi. “It’s really good news that laughter treatment is a good intervention that could help reduce inflammation and decrease the risk of heart attack and stroke.”
