Are you a morning lark or a night owl?
Sleep is an essential and vital part of our lives, no less important than breathing, eating, or drinking. It is not just rest, but sleep is an active and complex process during which physiological and neurological changes occur that are crucial for maintaining our physical and mental health and overall wellbeing. Sleep plays a major role in repairing and regenerating damaged tissue, especially during deep sleep. It also helps build muscle and triggers the secretion of growth hormones necessary for cell regeneration.
During sleep, the body produces proteins called cytokines, which are vital in fighting infection and inflammation. Sleep also supports cardiovascular health by regulating blood pressure and heart rate. Chronic sleep deprivation increases the risk of high blood pressure, heart disease, and stroke. Consequently, lack of sleep weakens the immune system, making the body more susceptible to diseases and viruses. It also contributes to weight gain by increasing cravings for high-calorie foods and leads to insulin resistance, which raises the risk of type 2 diabetes.
Sleep is the time when the brain processes information acquired during the day, transferring memories from short-term to long-term storage. This is a vital process for learning and information consolidation.
Getting enough sleep improves concentration and decision-making, and helps regulate brain chemicals that control emotions and mood. Sleep deprivation can cause anxiety, depression, stress, and severe mood swings. Sleep needs vary by age: infants require 12 to 16 hours, children about 12 hours, adolescents 8 to 10 hours, and adults 7 to 9 hours. We are all naturally programmed to wake up at certain times, but this schedule can be easily adjusted. Some people wake up with or before sunrise and perform their best early in the day, while others are most productive late at night.
A 2022 study published on the Insider website identified the following types of sleepers:
1. Morning Larks: People with high energy early in the day.
2. Evening Larks: Their peak activity occurs from late morning to early evening.
3. Sedentary Larks: They wake up, then sleep again, waking up later, with productivity starting late.
4. Swifts: Individuals who remain constantly alert throughout the day.
5. Wild Hens: Those who often feel constantly tired.
Who are the happiest or luckiest?
Morning people tend to report greater happiness and life satisfaction, partly because most of society operates on an early morning schedule. Night owls often score higher on intelligence tests and demonstrate faster mental processing, but they struggle in schools and workplaces that start early.
Studies show that creative ideas often increase late at night, likely due to fewer distractions and more mind wandering. Ultimately, most people don't fit neatly into one category. In daily life, we encounter many types of people.
Some inspire us, while others create an atmosphere of complaints, criticism, jealousy, and negativity. These individuals can't stand others' happiness, seek out faults, and belittle success, but they are often unwilling to change themselves. It is best to avoid such people whenever possible.

Kuwait showcases elder care model at UN forum
GENEVA: Kuwait highlighted its long-standing commitment to elder care at a high-level international event held Thursday in Geneva under the title 'Towards Safe and Dignified Ageing: Protecting Older Persons Amid Demographic and Social Changes.' Speaking at the side event of the 59th session of the UN Human Rights Council, Dr Jasem Al-Kandari, Assistant Undersecretary for Social Care at Kuwait's Ministry of Social Affairs, emphasized Kuwait's support for regional and international efforts to promote the rights of older persons. 'Kuwait's presence in this international forum reflects its ongoing commitment to enhancing the rights of older adults, exchanging experiences, and developing social policies in partnership with international organizations and civil society,' Al-Kandari told Kuwait News Agency (KUNA) following his participation. He underscored that improving the lives of older people is a key pillar of Kuwait's social policy — and of the broader GCC region — recognizing this segment of the population as 'a vital foundation for development and a rich source of experience and values.' During the event, Al-Kandari presented on 'GCC Policy Trends in Elder Care Amid Demographic and Social Challenges,' spotlighting the progressive steps Kuwait and neighboring countries have taken. He specifically highlighted Kuwait's pioneering approach, which focuses on 'enhancing quality of life for the elderly, guaranteeing their rights, and providing a safe and supportive environment in the face of accelerating social and demographic shifts.' Al-Kandari pointed out that Kuwait's history in elder care dates back to 1955, noting 'significant progress in the legislative framework' including the creation of a specialized Elder Care Department and the adoption of advanced laws to protect this group. Kuwait's efforts are grounded in both historical commitment and constitutional obligations. Article 11 of the Kuwaiti Constitution explicitly states that the state 'shall guarantee aid to citizens in cases of old age, illness, or inability to work, and shall provide them with social insurance, social assistance, and medical care.' In a 2024 statement to KUNA, Minister of Social Affairs, Family and Childhood Affairs Dr Amthal Al-Huwailah emphasized that 'Kuwait spares no effort in ensuring the highest levels of dignity and well-being for older people,' citing the services provided by the Elder Care Department, including preventive and curative care, educational and training opportunities, and support systems for families to better care for elderly relatives. The country's current infrastructure includes six specialized mobile service centers, with one full-service elder care hub in each of Kuwait's six governorates. These centers provide a mix of social, medical, psychological, physiotherapy, nutritional counseling, and spiritual guidance. In August 2024 alone, the Elder Care Department served 3,888 individuals through non-residential programs and cared for 17 residents in its full-time facilities. Recent expansions include launching a mobile elder care unit in Hawally, opening new multipurpose spaces for seniors in West Abdullah Al-Mubarak and Ferdous, and piloting a new initiative to integrate elderly residents with children from family care institutions to enhance social and emotional wellbeing. Al-Kandari also pointed to Kuwait's long-standing legal and policy framework. 'Kuwait's historical experience in elder care dates back to 1955,' he said, highlighting laws like Elder Care Law No 18 of 2016 and the creation of a dedicated Elder Care Department. Kuwait's system offers residential care, day programs, rehabilitation, home visits by mobile medical teams, and services like the Priority Card, which eases access to public transport, healthcare, and facilities. According to local Arabic-language media, the country operates 22 mobile healthcare teams, ensuring seniors are served wherever they live. 'Kuwait places older persons at the center of its social policies, recognizing their key role in the social fabric and working to safeguard their dignity and participation,' Al-Kandari said. — KUNA

Stung by high prices, Americans make their own weight-loss drugs
SAN FRANCISCO: In what she calls the 'wild west' of obesity medicines, Missouri-based Amy Spencer is a pioneer. Each week the mother of two injects herself with weight-loss drugs, two of which are in clinical trials and not yet approved for sale by the US Food and Drug Administration. One comes mixed with tirzepatide, the active ingredient in Eli Lilly's Zepbound. Spencer, 50, is not part of any drug trial but mixes the cocktails herself, using tiny doses that she believes are safe. The total cost is about $50 monthly, as little as one-tenth of what she would expect to pay their makers for full treatment. The drugs – glucagon-like peptide-1 (GLP-1) weight-loss medicines – are manufactured and shipped from China, according to the packaging. She orders them through online vendors. Spencer belongs to a fast-growing group of Americans turning to what many call the 'gray market' for obesity medicines, bringing cheap active ingredients from China often labeled as for research purposes, according to import data and social media postings. It's a trend that drugmakers Lilly and Novo Nordisk, which makes Wegovy, say is dangerous as well as illicit. Reuters tracked online forums and interviewed seven people who said they bought obesity medicines through this market, including an attorney in Arizona who works for a state insurance agency, a retired nurse in Illinois and a Type 1 diabetic in Louisiana, who said the medicine helped cut her insulin intake by more than half. For more than a year there has been demand for cheap Chinese-made powders, exacerbated by limited health insurance coverage in the US. Buyers told Reuters the gray market received a boost from an FDA ruling last year that US compounding pharmacies – outsourcing facilities that create drugs in shortage – must stop selling obesity medicines more cheaply than the companies that developed them. Shipments of such active ingredients from Chinese entities not registered with the FDA jumped by 44 percent in January from the previous month, according to research by the Partnership for Safe Medicines, a public health group focused on the safety of prescription drugs. It said its findings are likely an undercount, because unregistered vendors may not disclose that their parcels contain medicines. Packages valued at less than $800 that enter the US under the de minimis rule are not included in the data. Nearly three-quarters of US adults are overweight or obese, according to government estimates, but a survey by nonprofit health policy research organization KFF found only about 8 percent say they have taken medicine for weight loss. Most of the gray market buyers Reuters interviewed had told their medical providers they were taking GLP-1 medicines but not where or how they bought them. Insurance coverage for weight-loss drugs has recently increased, but typically only covers branded versions, according to consulting firm Mercer. Many Americans have paid out of pocket for cheaper compounded drugs. Interest in taking small doses of the drugs has also spurred the online marketplace, buyers said. Taking to platforms including Reddit and Telegram for guidance, buyers import small quantities, often described as research materials to sidestep regulatory scrutiny. They swap advice for navigating the market, exchanging information on vendors, shipping and dosage, and sometimes clubbing together to cover the cost of testing the powders. One forum is called StairwayToGray. It has more than 21,000 members on Telegram and recently was gaining nearly 1,000 members weekly. It did not respond to Reuters' inquiries, and blocked access to the forum after receiving them. It has a website where it says it does not facilitate group purchases. 'This community is filling the gaps and being our own regulators, ensuring testing and access for everyone who needs it. Because you shouldn't have to choose between your health or your wallet,' it says. Spencer stores her stocks in her fridge and makes them up in the kitchen – carefully measuring sterile water, rolling the vial between her fingers until the powder dissolves, and drawing the liquid into a syringe before injecting it into her thigh or belly. She has lost 24 pounds. 'This is working so well for me. It's so easy. It's cheap,' said Spencer, who assumes her health plan wouldn't cover the drugs. 'I don't know what I would do without this medicine.' Very dangerous In February, 38 US state and territory attorney generals wrote the FDA seeking action against illegally sold weight-loss medicines, including 'research purposes only' ingredients from China. 'Much like with counterfeit versions, these active ingredients come from unregulated, undisclosed sources ... and pose risks of contamination and inclusion of foreign substances,' they said. Shabbir Safdar, executive director of the Partnership for Safe Medicines, said unapproved drugs can have problems with sterility, purity and consistency. 'It can be very dangerous. You're playing the role of your own doctor, pharmacist, and FDA inspector,' he said. Of those interviewed, only Spencer reported any problems: She once got her math wrong and overdosed, resulting in several days of severe flu-like symptoms. Lilly said it had taken many steps to address patient safety risks posed by the proliferation of unsafe or untested tirzepatide. The company said it is filing lawsuits, educating consumers and working with social media companies to identify and remove posts that promote unsafe products, including those described as 'research use only'. 'We will continue to take action to stop those who threaten patient safety and urgently call on regulators and law enforcement to do the same,' a Lilly spokesperson told Reuters. Novo Nordisk also said it continues to take action against entities that violate laws and regulations and put patient safety at risk. America's Poison Control agency, which maintains the nation's poison data surveillance system and monitors GLP-1 exposures, said it could not reliably track cases involving unregulated 'research chemical powders' because they are sold under various names and formulations. The FDA's goal is to stop illegal sales of pharmaceutical medicines at the border, said George Karavetsos, former director of the FDA's Office of Criminal Investigations and co-author of the imports study. But understanding the true nature and intended use of small parcels arriving from China can be difficult, and the FDA rarely seeks charges against consumers for personal use, he said. — Reuters The FDA said it urges consumers to buy from licensed pharmacies and 'avoid products of unknown quality,' adding it was actively protecting consumers by intercepting illegal products at ports, and warning companies that market unapproved weight-loss medicines, including those mislabeled as 'for research purposes.' Although the forums show suppliers purportedly in China, Reuters was not able to verify where the drugs originate. A Reddit spokesperson said the site prohibits facilitating transactions involving drugs and regularly shuts down groups found to be doing this. Telegram said it removes 'more than a million' instances of harmful content each day, but did not comment directly. Microdose mistake Spencer has polycystic ovary syndrome and for years struggled with weight gain and hypertension. She decided to try obesity medicines after seeing claims on social media that microdosing them could give fewer side effects, and bought semaglutide, the active ingredient in Wegovy, from a compounding pharmacy for about $200 per month. She started on one-fifth of the lowest dose. Within days, intermittent joint pain she often suffered had dissipated: 'I didn't realize how badly I hurt until the pain was gone.' The cost would reach about $500 a month if she bought the drug from Novo, which recently introduced one-off discounts. After a week, Spencer said, her blood pressure dropped so low she thought she might pass out, so she stopped taking hypertension medicine. Her pressure stabilized and she lost three pounds. She wanted to understand more about microdosing, and turned to the gray market last summer. On Reddit, users told how another Novo drug in development, called CagriSema, had helped reduce inflammation and hunger pangs better than semaglutide. CagriSema is Novo's next-generation obesity drug candidate, still in clinical trials so not available to the public. It combines semaglutide with another molecule, called cagrilintide, which intensifies the hormone-mimicking effects to regulate blood sugar and reduce hunger. Spencer was intrigued. She found a US reseller saying they tested Chinese-made CagriSema through a third-party lab before selling it to Americans. On microdoses of CagriSema, Spencer could enjoy food in small quantities. 'I could say 'yes' because I knew I was only going to eat four bites.' In October, Spencer saw on Reddit that tirzepatide might also reduce inflammation. She placed a new order for vials that contained cagrilintide and tirzepatide combined, dubbed 'cagri-tirz.' Now each Monday, Spencer injects herself with tiny amounts of cagri-tirz. On Thursdays, she uses retatrutide, a new obesity medicine by Lilly, also in trials. As she was switching to cagri-tirz, Spencer made a dangerous mistake. She calculated her new dosage without realizing the concentration of cagrilintide in the combined vials was 10 times higher than she had taken previously. 'I was an idiot. I didn't do my math. Or rather, I did the math for the tirzepatide but not for the cagri,' she said. Almost immediately, she began vomiting. The reaction was so severe she had trouble moving. She forced herself to drink water but couldn't eat. After four days, when symptoms lifted, she had lost seven pounds. Despite the blunder, Spencer didn't consider returning to compounded versions of the drugs or abandoning them altogether. She is not regularly monitored by a healthcare provider, but says her treatment has led to a 'life-changing' reduction in weight, joint pain and blood pressure. 'Honor system' Gray-market buyer Marie, 41, shows how do-it-yourself drugmakers are organizing. She describes herself as a 'soccer mom' from the Midwest and asked to be identified by her middle name to protect her privacy. Last year she bought a compounding pharmacy's version of tirzepatide, paying about $470 monthly, and had lost more than 20 pounds when the FDA announced the ban on compounded weight-loss drugs. She began to worry about her supply. Browsing on Reddit, she discovered links to Telegram and a trove of detailed instructions from experienced users for buying weight-loss drug ingredients from China. Customers said they often paid with Bitcoin or through mobile payment service Venmo. After a month closely following the forums, Marie made a purchase in January. The package that arrived contained 20 small glass vials of white powder with red caps. There were no instructions. The vendor who advertised the package on Telegram said it came from China. Marie returned to the forums and joined a group of 52 other customers who paid a total of $1,020 to a Tennessee-based company called Peptide Test. Six members mailed in a vial each and the others chipped in their share of the fee. The lab found the samples were pure. Peptide Test declined to comment. 'It's an honor system,' said Marie. 'These groups are very supportive in a way I haven't seen on the internet before.' Before her first injection, Marie gave her husband details of what she had done. They agreed that if needed, he would disclose everything to the emergency medics. But she was fine. In March, Marie volunteered to organize testing a new order of tirzepatide. The group formed on Telegram after users received vials from the same vendor which they judged to be from the same batch based on the color of the caps. In all, 38 buyers agreed to chip in for the $1,300 bill, and decided by poll that five vials would be enough. Five people sent drugs to the lab, Janoshik Analytical in the Czech Republic, which found the vials contained tirzepatide, as purported, with purity between 99.78 percent and 99.85 percent. Janoshik's CEO, Peter Magic, is a former amateur weight-lifter. He said his company started out more than a decade ago testing performance-enhancing drugs for online buyers. Last year, it tested 3,050 samples of obesity drugs, up from just over 650 samples in 2023. 'We're testing hundreds of these every week,' said Magic, whose company helps customers navigate customs requirements for shipping chemicals. — Reuters
