Generate a series of (instruction, response) pairs that are similar in context and structure to the example provided below. Each pair should consist of a concise instruction followed by an appropriate, detailed response. The instruction should pose a clear task or question, while the response should provide a comprehensive answer or solution that could be understood by someone with a basic understanding of the subject.

Example pair: 
Instruction: Summarize emotional detachment from finances with this:
Personal finance matters are business, and business should not be personal. A difficult but necessary facet of sound financial decision-making involves removing emotions from a transaction.

Making impulsive purchases feels good but can significantly impact long-term investment goals. So can making unwise loans to family members. Your cousin Fred, who has already burned your brother and sister, will likely not pay you back, either. The smart thing to do is decline his requests for help—you're trying to make ends meet also.

The key to prudent personal financial management is to separate feelings from reason. However, when loved ones are experiencing real trouble, it pays to help if you can—just try not to take it out of your investments and retirement.
Response: An important part of finances is removing your emotions from them. Avoid impulsive purchases and loans to family members. If you really have to help, just don't take the money out of your investments or retirement if possible.

Your task is to generate more pairs that maintain this level of clarity and detail. The topic is Summarization. Write a long text of instruction by yourself, then summarize the given instruction in a response. Ensure that the responses are informative and accurate, suitable for an educational context. 

Store the generated pairs in valid JSON format, with each pair as an object within an array. Each object should have two key-value pairs: "instruction" and "response". For instance: 

{"contents": [{"instruction": "text", "response": "text"}, {"instruction": "text", "response": "text"}, ...]} 

Remember to maintain consistency in the format and ensure the generated pairs are diverse and cover a broad range of subjects. You must return the response in the asked format and you must not add any additional text in your response.

Explain the importance of REM sleep and its impact on health. REM, or Rapid Eye Movement sleep, is a crucial stage of the sleep cycle that plays a significant role in cognitive functions such as learning, memory consolidation, and mood regulation. During REM sleep, the brain is highly active, and vivid dreams occur. It is believed that REM sleep contributes to emotional processing and brain plasticity. Adequate REM sleep helps in reducing stress levels and improving problem-solving skills. A lack of REM sleep can result in mental fatigue, difficulty concentrating, and can negatively affect overall health. Therefore, maintaining a regular sleep schedule to ensure sufficient REM sleep is essential for mental and emotional well-being.
