However, research suggests that small, sustainable changes are more effective in the long run. This concept is known as the "aggregation of marginal gains." Instead of vowing to run for an hour daily (which you might quit after a week), try a 10-minute brisk walk after dinner. This adds regular physical activity without overwhelming you. Similarly, swap one sugary drink per day for water or herbal tea. This simple act of portion control and choosing healthy alternatives significantly reduces weekly sugar intake. Stress management can also start small. A five-minute mindfulness meditation or some deep breathing before bed can improve sleep quality. Good sleep hygiene, like keeping electronic devices out of the bedroom, prevents them from interfering with your sleep patterns. Remember, moderation is key. You don't need to eliminate treats entirely; just enjoy them occasionally. The goal is consistency. By focusing on these gradual adjustments, you build a personalized and sustainable healthy lifestyle that becomes a natural part of your life, not a burden. 1. What is the main idea of the passage? A. Major life changes are necessary for health. B. Only intense exercise can improve cardiovascular health. C. Small, consistent changes are better for long-term health. D. Stress management is the most important part of a healthy life. 2. What does the author suggest as an alternative to a long run? A. Complete rest. B. Strength training at the gym. C. A short brisk walk. D. A high-sugar energy drink. 3. According to the passage, what can improve sleep quality? A. Checking social media in bed. B. Short mindfulness practice before bed. C. Drinking coffee in the evening. D. Completely eliminating all daily stress. 4. The word "swap" in paragraph 2 is closest in meaning to ______. A. increase B. exchange C. eliminate D. discover 5. What is the author's attitude towards "treats" like sugary foods? A. They should be completely banned. B. They are the main cause of health problems. C. They can be enjoyed in moderation. D.
