  Good morning and welcome to Morning Medical with Dr.

• 0:08
  I'm Dr.
• 0:09
  Chi-Ming Chow, and today we're diving into a topic that's particularly relevant as we
• 0:14
  approach the sunnier months: sunburn.
• 0:17
  Despite numerous health warnings about sun exposure, many of us still find ourselves with
• 0:22
  sunburns at least once a year.
• 0:25
  In fact, a large study found that over a third of adults and nearly sixty percent of children
• 0:30
  and teenagers in the United States reported getting at least one sunburn over a year.
• 0:38
  So, what exactly is sunburn?
• 0:41
  Simply put, it's skin damage resulting from exposure to the sun's ultraviolet rays.
• 0:48
  While most sunburns are mild and can be treated at home, they do increase your risk for
• 0:53
  melanoma and other types of skin cancer.
• 0:56
  The damage occurs when ultraviolet rays penetrate the skin, causing it to redden and
• 1:02
  become irritated.
• 1:03
  Underneath, the situation is more complex as ultraviolet light can alter your DNA, leading
• 1:10
  to premature aging of the skin and, over time, potentially resulting in skin cancers.
• 1:17
  Sunburn can occur more quickly depending on your skin type, the sun's intensity, and the
• 1:22
  duration of exposure.
• 1:24
  While people with lighter skin tend to burn more easily, those with darker skin can also
• 1:30
  suffer sunburns that are often less visible but equally damaging.
• 1:34
  The types of sunburn vary based on how deeply the ultraviolet rays penetrate the skin.
• 1:40
  First-degree sunburns affect the outer layer of skin and typically heal within a week.
• 1:47
  Second-degree sunburns reach the middle layer of skin and may cause blisters, requiring weeks
• 1:53
  to heal.
• 1:54
  Third-degree sunburns are rare and involve severe damage to all skin layers, often
• 2:00
  requiring immediate medical attention.
• 2:03
  When it comes to signs of sunburn, you'll notice your skin hurting and possibly turning
• 2:08
  red.
• 2:09
  Severe cases might lead to swelling, blisters, and even flu-like symptoms such as fever,
• 2:14
  chills, nausea, headache, and weakness.
• 2:19
  As the skin heals, peeling and itching are common as the body sheds sun-damaged cells.
• 2:25
  For relief, several home remedies can be effective.
• 2:28
  Applying cold compresses or taking a cool bath can soothe the burn.
• 2:33
  Creams or gels containing menthol, camphor, or aloe vera can help relieve discomfort.
• 2:39
  Over-the-counter hydrocortisone cream and nonsteroidal anti-inflammatory drugs like
• 2:45
  ibuprofen can also be beneficial.
• 2:47
  It's crucial to stay hydrated and avoid further sun exposure until the sunburn heals.
• 2:53
  Importantly, do not pop any blisters, as this can lead to infection.
• 2:58
  You should seek medical attention if you experience severe symptoms such as a high
• 3:02
  fever, extensive blistering, or signs of dehydration.
• 3:07
  Additionally, sunburns in infants under one year require immediate medical evaluation.
• 3:13
  Persistent changes in skin marks or moles should also be checked by a doctor, as they
• 3:18
  could indicate skin cancer.
• 3:21
  Preventing sunburn is key to avoiding long-term skin damage.
• 3:25
  Limit sun exposure between 10 a.m.
• 3:27
  and 4 p.m.
• 3:28
  when the sun's rays are strongest.
• 3:31
  Use broad-spectrum sunscreen with an SPF of at least 30, and reapply it every two hours or
• 3:36
  more frequently if swimming or sweating.
• 3:39
  Wear protective clothing, such as hats and long sleeves, and remember that even on cloudy days,
• 3:45
  ultraviolet rays can penetrate through clouds.
• 3:49
  In summary, while sunburns might seem like a minor inconvenience, they can have serious,
• 3:54
  long-term effects on your skin health.
• 3:57
  Taking preventive measures and knowing how to treat sunburn effectively can help you enjoy
• 4:02
  the sun safely.
• 4:03
  Stay tuned as we continue to explore more health topics in the next segment.
• 4:10
  Vitamin A is a crucial nutrient that plays a significant role in maintaining healthy vision,
• 4:16
  supporting a robust immune system, and ensuring proper growth and development.
• 4:21
  Unfortunately, when you do not consume enough vitamin A in your diet, you risk developing a
• 4:27
  vitamin A deficiency.
• 4:28
  Over time, this deficiency can lead to serious health issues, including vision problems,
• 4:34
  weakened immunity, and even death.
• 4:38
  Vitamins, including vitamin A, are essential components of our diet.
• 4:42
  They are a group of nutrients that, even in small amounts, contribute significantly to our
• 4:48
  overall well-being.
• 4:49
  Vitamin A, in particular, is necessary for healthy eyes, good vision, and healthy skin.
• 4:56
  It also plays a critical role in helping our bodies fight off infections.
• 5:00
  The human body cannot produce vitamin A on its own, so it is essential to include it in your
• 5:05
  diet through various sources.
• 5:07
  You can find vitamin A in dark green leafy vegetables, sweet potatoes, carrots, squash,
• 5:14
  pumpkin, and low-fat dairy foods, among other things.
• 5:18
  These foods are rich in carotenoids, which are yellow, orange, and red organic pigments
• 5:24
  produced by plants and algae that the body converts into vitamin A.
• 5:29
  Because of this, it is vital to consume a balanced diet that includes these vitamin
• 5:34
  A-rich foods to prevent deficiency.
• 5:38
  While vitamin A deficiency is uncommon in countries where people have access to a variety
• 5:43
  of foods, it is a serious issue in regions with tough socioeconomic conditions and limited
• 5:49
  access to vitamin A-rich foods.
• 5:52
  For instance, in parts of Africa and Southeast Asia, it is estimated that 190 million
• 5:58
  preschoolers suffer from vitamin A deficiency due to a lack of carotenoids in their diets.
• 6:05
  The deficiency is often exacerbated by serious infections, such as measles, which can further
• 6:11
  deplete vitamin A levels.
• 6:13
  In the United States, certain groups may be at risk for vitamin A deficiency.
• 6:19
  People with specific liver diseases, pregnant individuals, and adults with gastrointestinal
• 6:25
  disorders that interfere with the absorption of vitamin A, such as celiac disease or liver
• 6:31
  cirrhosis, may be more susceptible.
• 6:34
  It's important for those affected to consult a doctor before taking supplements, as improper
• 6:39
  supplementation can be dangerous.
• 6:42
  The symptoms of vitamin A deficiency can vary in severity.
• 6:47
  Some people might experience night blindness, where they have trouble seeing in low light
• 6:51
  conditions, which can progress to complete night blindness.
• 6:56
  Others may develop xerophthalmia, a condition where the eyes become very dry and crusted,
• 7:01
  potentially damaging the cornea and retina.
• 7:04
  Additionally, vitamin A deficiency can lead to frequent infections, Bitot spots, skin
• 7:11
  irritation, keratomalacia, keratinisation, stunted growth, and fertility issues.
• 7:19
  Diagnosing vitamin A deficiency typically begins with an eye examination and a review of
• 7:24
  the patient's medical history.
• 7:26
  A blood test may be conducted to measure vitamin A levels in the blood.
• 7:30
  In regions with limited medical access, diagnosis is often informal.
• 7:35
  For example, if a mother reports her child experiencing night blindness, a doctor might
• 7:40
  suspect vitamin A deficiency as the underlying cause.
• 7:44
  The treatment for vitamin A deficiency depends on its severity.
• 7:48
  Mild deficiencies can often be addressed by increasing the intake of vitamin A-rich foods.
• 7:54
  However, more severe cases may require high-dose vitamin A supplements initially,
• 7:59
  followed by lower doses until symptoms improve.
• 8:03
  It is important to note that vision loss due to corneal scarring from vitamin A deficiency is
• 8:08
  generally permanent.
• 8:10
  To prevent vitamin A deficiency, it is important to consume a diet rich in foods that
• 8:15
  contain vitamin A.
• 8:17
  These include liver, oily fish, shellfish, and cod liver oil, which can be consumed as part of
• 8:23
  meals or as supplements.
• 8:25
  Orange vegetables, such as sweet potatoes, pumpkins, carrots, and squash, are particularly
• 8:31
  high in vitamin A, as are green leafy vegetables like spinach and lettuce.
• 8:36
  Dairy products and certain fruits, like ripe mangoes and apricots, are also excellent
• 8:42
  sources.
• 8:43
  In conclusion, avoiding vitamin A deficiency is about maintaining a balanced diet.
• 8:50
  While supplements are available, obtaining vitamin A through food is generally more
• 8:55
  beneficial for the body.
• 8:57
  If you're concerned about your vitamin A levels, consult your doctor to have them
• 9:01
  checked.
• 9:03
  Regular monitoring is especially important for individuals with underlying conditions that
• 9:08
  could lead to various deficiencies.
• 9:11
  Although vitamin A deficiency is rare in areas with ample food sources, it can still affect
• 9:17
  some individuals, making awareness and prevention crucial.
• 9:22
  Let's talk about a new trend that's gaining popularity in the world of
• 9:26
  nutrition—fibermaxxing.
• 9:29
  This term refers to the effort to meet or exceed the recommended daily intake of dietary
• 9:34
  fiber.
• 9:36
  As more and more products are being promoted with high or added fiber, it's important to
• 9:41
  understand the potential benefits and pitfalls of this trend.
• 9:45
  Fiber is a type of carbohydrate found in plants that your body cannot digest.
• 9:49
  It plays a crucial role in feeding gut bacteria and moving food through your digestive system.
• 9:55
  While fiber might not be a topic people want to discuss at a dinner party, its health benefits
• 10:00
  are noteworthy.
• 10:02
  There are two main types of fiber: soluble and insoluble.
• 10:06
  Soluble fiber dissolves in water and forms a gel-like material that feeds gut bacteria.
• 10:12
  You can find it in foods like oats, peas, beans, apples, and carrots.
• 10:17
  Insoluble fiber, on the other hand, does not dissolve in water and helps move food through
• 10:22
  the digestive system.
• 10:24
  It is present in whole wheat flour, popcorn, wheat bran, nuts, green beans, and potatoes.
• 10:33
  Studies have demonstrated that fiber can lower cholesterol levels, regulate blood sugar, and
• 10:38
  promote weight loss by making you feel fuller.
• 10:41
  It may also offer protection against heart disease, diabetes, diverticulitis, and colon
• 10:47
  cancer.
• 10:49
  With the rising use of GLP-1 weight loss drugs, which naturally slow digestion, fiber is
• 10:55
  gaining renewed interest since it can help prevent constipation, a common side effect of
• 11:00
  these medications.
• 11:02
  So, how much fiber do we need?
• 11:05
  The United States Department of Agriculture recommends that adults aim for 14 grams of
• 11:10
  fiber for every 1,000 calories consumed, which translates to about 25 grams for women and 38
• 11:18
  grams for men each day.
• 11:20
  Unfortunately, most Americans only consume about two-thirds of the recommended amount.
• 11:26
  To put things in perspective, one cup of raspberries contains 8 grams of fiber, a banana
• 11:31
  has 3.2 grams, half a cup of avocado provides 5 grams, and one cup of lima beans offers 13.2
• 11:39
  grams.
• 11:40
  A serving of Fiber One cereal packs 18 grams of fiber into just two-thirds of a cup.
• 11:47
  When it comes to increasing your fiber intake, experts advise focusing on whole foods rather
• 11:53
  than packaged products with added fiber.
• 11:56
  Long-term studies have shown the benefits of fiber consumption primarily from whole foods.
• 12:03
  These foods not only provide fiber but also offer other essential nutrients.
• 12:08
  For example, an apple contains 4.8 grams of fiber along with water, vitamins, and minerals.
• 12:16
  The Mayo Clinic recommends adding more fiber to your diet by choosing cereals with at least 5
• 12:21
  grams of fiber per serving, opting for breads with at least 2 grams of fiber per serving, and
• 12:26
  trying grains like brown rice, whole-wheat pasta, and quinoa.
• 12:32
  When baking, consider substituting whole-grain flour for white flour and adding wheat bran to
• 12:38
  muffins and cookies.
• 12:39
  Aim for five or more servings of fruits and vegetables daily, ensuring that canned fruits
• 12:44
  are packed in juice and canned vegetables are low in sodium.
• 12:49
  However, it's important to proceed with caution when increasing your fiber intake.
• 12:53
  There is no defined upper limit for fiber consumption, but a rapid increase can lead to
• 12:58
  uncomfortable gas and bloating.
• 13:01
  It's advisable to gradually increase fiber intake while drinking plenty of water to help
• 13:06
  your digestive system adjust.
• 13:08
  People with specific dietary sensitivities or allergies should be cautious, as some
• 13:14
  fiber-added products may contain gluten, soy, shellfish, or psyllium husk.
• 13:21
  Lastly, while focusing on individual nutrients like fiber is popular, experts remind us that
• 13:28
  it's more important to aim for a balanced diet.
• 13:32
  Rather than concentrating on specific nutrients, strive to consume a variety of
• 13:36
  healthy foods that contribute to overall well-being.
• 13:40
  Remember, we don't just need nutrients; we need a diet rich in whole, nutritious foods.
• 13:47
  There's a growing concern in Canada regarding the prevalence of sports gambling
• 13:51
  advertisements, with over forty senators recently signing a petition addressed to Prime
• 13:56
  Minister Mark Carney.
• 13:59
  This petition calls for a complete ban on all sports gambling ads, citing the "very real
• 14:05
  harm" these ads cause.
• 14:07
  The senators argue that the advertisements expose people of all ages to a constant barrage
• 14:13
  of messages urging them to participate in sports betting, similar to how cigarette
• 14:18
  advertising was banned to address public health issues.
• 14:22
  The Canadian Medical Association Journal has also expressed concerns, releasing an editorial
• 14:28
  urging restrictions on these ads.
• 14:30
  The editorial highlights the normalization of gambling as a pastime and the potential risks
• 14:35
  it poses, particularly to children.
• 14:38
  With sports betting legalized in Canada since 2021, individuals can now place bets on single
• 14:44
  games using their smartphones.
• 14:47
  This ease of access has led to a notable increase in gambling participation, although
• 14:52
  recent surveys indicate a slight decline in the number of Canadians placing sports wagers.
• 14:58
  Experts are worried about the impact of gambling ads on youth.
• 15:02
  Dr.
• 15:03
  Shawn Kelly, a pediatrician with the Canadian Society of Addiction Medicine, shared a
• 15:08
  personal anecdote about his young son confusing gambling terms, which prompted him to
• 15:14
  investigate the effects of such advertising on children.
• 15:17
  He warns that gambling ads can worsen mental health, increase school absenteeism, and lead
• 15:23
  to criminal behavior in minors.
• 15:25
  For those with severe gambling disorders, the risk of suicide is alarmingly high.
• 15:31
  Psychology professor Steve Joordens from the University of Toronto adds that young people
• 15:36
  are particularly vulnerable to gambling ads because they often seek quick rewards.
• 15:42
  These ads glorify gambling, presenting it as an exciting and normal aspect of being a sports
• 15:47
  fan.
• 15:48
  Joordens explains that the allure of random rewards makes gambling addictive, as people
• 15:54
  continue to chase the next win, often leading to significant debt.
• 15:59
  The senators' petition is a step toward addressing these concerns, urging the
• 16:03
  government to act similarly to how cigarette advertising was tackled.
• 16:06
  Although the Senate has passed a bill to ban sports gambling ads, it still requires approval
• 16:11
  from the House of Commons.
• 16:12
  The petition aims to pressure the government into supporting this legislative effort,
• 16:16
  emphasizing the need to limit the exploitation of human vulnerability for profit.
• 16:22
  Dr.
• 16:23
  Kelly supports the petition, viewing it as a positive move toward reducing the harmful
• 16:27
  effects of sports gambling ads.
• 16:29
  He believes that limiting such advertisements could protect vulnerable populations,
• 16:34
  particularly adolescents, from the potential negative impacts of gambling.
• 16:39
  As winter approaches, public health officials and infectious disease experts are raising
• 16:45
  alarms about this year's flu season.
• 16:47
  The United Kingdom's National Health Service has issued an "SOS" warning, indicating that
• 16:54
  this winter could bring one of the most severe influenza waves in recent memory.
• 16:59
  Dr.
• 16:59
  Jacob Glanville, Chief Executive Officer of Centivax, a biotechnology company based in San
• 17:05
  Francisco, warns that this flu season is predicted to be unusually bad.
• 17:11
  Britain is experiencing an early and intense flu wave, with cases tripling compared to last
• 17:16
  year.
• 17:17
  In Australia, last year's flu season was reportedly the worst ever, a pattern that often
• 17:22
  foreshadows trends in the Northern Hemisphere.
• 17:25
  Dr.
• 17:26
  Ravi Jhaveri, a professor of pediatrics at Northwestern University Feinberg School of
• 17:31
  Medicine, notes early signs of flu activity in parts of the United States.
• 17:36
  He highlights a concerning trend: vaccination rates have continued to decline since the
• 17:42
  pandemic, which could contribute to a challenging flu season ahead.
• 17:47
  The H3N2 strain, which is currently more prevalent, is associated with lower vaccine
• 17:52
  effectiveness.
• 17:54
  Dr.
• 17:55
  Glanville points out that this year's flu vaccines contain a mix of strains from 2021,
• 17:59
  2022, and 2023, which may not effectively match the current virus.
• 18:03
  This mismatch could lead to reduced protection against the flu.
• 18:07
  Moreover, the flu virus is known for its constant mutation, making it difficult for
• 18:12
  immune systems to recognize and combat it.
• 18:15
  This year, the flu virus seems to be spreading earlier than usual, though researchers are
• 18:19
  unsure why.
• 18:21
  Dr.
• 18:22
  Jhaveri explains that the timing of flu seasons can vary, and there might be a shift in how
• 18:26
  respiratory viruses, like the flu and RSV, interact.
• 18:30
  With more prevention options available for RSV, the overall pattern of respiratory viruses may
• 18:35
  have changed.
• 18:37
  Despite the challenges, vaccination remains crucial.
• 18:40
  While protection from the flu shot might be partial, it still offers some defense,
• 18:45
  especially for high-risk groups such as older adults, individuals with chronic conditions,
• 18:51
  and young children.
• 18:53
  Dr.
• 18:54
  Jhaveri emphasizes that vaccination is the first step in preventing the flu, noting that
• 19:00
  about half of the children who die from flu-related complications have no prior risk
• 19:06
  factors.
• 19:07
  For those hesitant to visit a clinic, a nasal spray vaccine has been approved for
• 19:12
  self-administration or for parents and caregivers to use at home.
• 19:17
  Meanwhile, Dr.
• 19:19
  Glanville's company, Centivax, is working on a universal flu vaccine, with human trials set to
• 19:25
  begin in early 2026.
• 19:29
  In conclusion, while this flu season presents significant challenges, taking preventive
• 19:34
  measures such as getting vaccinated can help mitigate the risks.
• 19:38
  Staying informed and following public health guidelines will be essential in navigating this
• 19:42
  unusually severe flu season.
