2026届高考英语一轮复习外刊精读学案—— 战胜脑雾的方法

2026高考一轮复习原创题 外刊精读 战胜脑雾的方法 Beating brain fog Do you ever wake up with a fuzzy feeling in your head, you can't concentrate on anything, or find your memory just isn't working as it should? You're not alone. 39% of British people said they suffer brain fog on a regular basis in a FutureYou Cambridge study. But why do we get brain fog, and can we do anything to prevent it? The technical word for brain fog is cognitive impairment. When you have it, you can't think as clearly as you normally can – just as if your brain was actually full of fog. Dr Brennan, a neuroscientist and author, says "Brain fog is different to these short-term disruptions, because it is persistent, occurs regularly and can interfere with the quality of your life, your relationships, and your work". The reality is that no-one knows exactly what causes it, though theories include chemical or blood flow changes in the brain, and low-level inflammation. What we do know are factors that make it worse. Fatigue, for example, is a key contributor to brain fog, making it hard to stay focused. This is because sleep deficiency can change activity in some parts of the brain, which means processing and recalling detail becomes harder. Pain and anxiety can also contribute to it – they interfere with cognitive speed because they are distracting. There are also medical conditions that can make it worse, like long Covid or autoimmune conditions like lupus disease. So, if you're suffering from brain fog, what can you do to fix it? One thing you can do is avoid ultra-processed foods (UPFs). Dr Megan Rossi, the founder of The Gut Health Doctor, told the BBC that "UPFs are often low in essential nutrients like magnesium, omega-3 fatty acids and iron, all of which are crucial for brain function and mental clarity". Therefore, we should pack our diets with nutrient-rich foods like whole grains, vegetables and healthy fats. Blueberries are particularly rich in polyphenols and have been shown to improve cognitive function and memory in clinical trials. Hydration is also very important. So, if you feel a bit foggy, try to get more sleep and consider making some changes to your diet. 一、阅读理解 1.What physiological change is NOT mentioned as a possible cause of brain fog? A.
