Lip Health: Subtle Signs That May Point to Heart Problems
How Lip Changes Reflect Internal Health
Medical professionals emphasise that lips, much like skin and nails, reflect the body's overall state. Pale, swollen, cracked, or unusually pigmented lips often indicate imbalances in oxygen supply, blood flow, or nutrient levels. According to research published in the National Library of Medicine, lip health is closely tied to cardiovascular, respiratory, and nutritional well-being. This means that by simply paying attention to your lips, you might detect early signs of systemic problems.
Lip Health Signs Linked to Heart and Circulation Problems
1. Pale or Bluish Lips
Lips that appear pale or bluish may point to low oxygen levels in the blood. This could stem from anaemia, poor circulation, or respiratory issues. Persistent paleness is considered a potential red flag for cardiovascular problems and warrants medical evaluation.
2. Dry and Chapped Lips
While dry or cracked lips are common in cold or dry climates, chronic dryness can indicate more serious conditions. The National Institutes of Health (NIH) notes that ongoing chapping may be a sign of dehydration, vitamin deficiencies—especially B vitamins—or malnutrition. Since lips are sensitive to hydration levels, prolonged dryness should not be ignored.
3. Swollen Lips
Lip swelling may occur due to allergies, infections, or inflammatory conditions. However, sudden or recurrent swelling could be a warning sign of more serious issues, such as angioedema or immune responses. The American Academy of Dermatology (AAD) advises medical consultation if swelling persists.
4. Sores or Lesions
Recurring sores or blisters on the lips are often caused by viral infections like herpes simplex (cold sores) or canker sores. While common, frequent outbreaks may reflect weakened immunity or chronic stress, both of which indirectly affect heart health and overall resilience.
5. Cracks at the Corners of the Mouth
Known as angular cheilitis, cracks at the corners of the lips are typically linked to iron or vitamin B deficiencies, or fungal infections. Maintaining good nutrition and lip hygiene can help prevent this uncomfortable condition.
6. Discolouration or Unusual Pigmentation
Dark patches or unusual pigmentation on the lips may point to hormonal imbalances, medication side effects, or systemic issues. Some studies suggest lip discolouration can serve as an early sign of more serious internal problems, including those connected to circulation.
Takeaway
Although often overlooked, lip health is an important aspect of overall well-being. Changes in their appearance should not be dismissed as mere cosmetic issues. Staying hydrated, eating a balanced diet, and consulting a healthcare professional when unusual symptoms appear can help detect potential health problems early—sometimes even those linked to the heart.

7 Side effects of sleep medication you should know to prevent serious health risks
Many people struggle with sleep problems, and chronic insomnia affects a significant number of adults. While sleep medications, whether prescription or over-the-counter, can help you fall asleep, even occasional use comes with health risks. Over time, frequent use may contribute to serious issues such as difficulty with daily activities, memory decline, increased risk of death, and next-day drowsiness. Older adults may be especially vulnerable to falls and other complications. Understanding these risks and exploring safer alternatives, like Cognitive Behavioral Therapy for Insomnia (CBTI) and healthy sleep routines, can help you get better rest without harming your long-term health. How sleep medication affects your body and what to do about it Higher risk of disability Long-term use of sleep medications has been linked to a higher risk of disability, especially in older adults. A study published in the Sage journal analysed over five years of data on more than 6,700 adults aged 65 and older. Researchers found that both worsening insomnia symptoms and increased sleep medication use were associated with a 20% higher risk of disability in daily life for each year of elevated use or symptoms. Essentially, while these medications may help with falling asleep, their prolonged use may accelerate functional decline, making daily activities more difficult. Experts recommend discussing ways to gradually reduce dependence under medical supervision. Higher risk of dementia Some sleep medications, particularly those with anticholinergic effects, may increase the risk of cognitive decline. Anticholinergic drugs work by blocking certain neurotransmitters in the brain and are often found in sleep aids, some pain and anxiety medications, and allergy treatments like diphenhydramine (Benadryl). A study published in NIH linked long-term use of these drugs to a higher risk of Alzheimer's disease and other forms of dementia. Alarmingly, the effects may persist even after stopping the medication. Older adults should consult healthcare providers to review the ingredients of their medications and consider safer alternatives if possible. Higher risk of death Regular use of certain hypnotic sleep medications has been associated with increased mortality. Even occasional users taking between one and 18 pills per year had a 3.6 times higher risk. The study suggested that these medications may contribute to fatal outcomes indirectly, through heart disease, cancer, or other serious conditions. This highlights the importance of careful evaluation before committing to long-term sleep medication use. Higher risk of cancer Frequent use of sleep medications may be linked to an increased risk of developing cancer. People who take these medications regularly, around 130 doses or more in a year, appear to have a higher chance of developing cancer compared to those who rarely or never use them. While more research is needed to fully understand this connection, it raises concerns about long-term exposure to sleep medications and their potential impact on overall health. Limiting prolonged use and exploring safer sleep strategies is recommended. Next-day impairment Sleep medications can impair alertness the following day, nearly doubling the risk of motor vehicle accidents. Extended-release formulations pose the highest risk, and women are more susceptible due to slower drug metabolism. Activities that require full alertness should be avoided until the medication's effects have worn off. Higher risk of falls Older adults taking sleep medications may face an increased risk of falls. Insomnia itself raises fall risk, and sleep aids do not necessarily mitigate this danger. Impaired balance, memory, and situational awareness make nighttime mobility especially hazardous. Increased risk of pancreatitis Emerging research also links certain sleep medications, such as zolpidem, to a higher risk of acute pancreatitis. A study published in Psychopharmacology analysed over 22,000 adults and found that those taking zolpidem were seven times more likely to develop pancreatitis than individuals who never used the drug. While rare, this severe side effect underscores the importance of careful monitoring and regular consultation with a healthcare professional. Quitting sleep medications can be challenging, but non-drug approaches often provide effective long-term relief. Cognitive Behavioral Therapy for Insomnia (CBTI) is considered the gold standard, teaching strategies to reshape thoughts, behaviors, and routines that interfere with sleep. Research from Harvard University shows that CBTI is as effective as sleep medications initially, and its benefits last longer. Combining CBTI with lifestyle changes such as keeping a consistent sleep schedule, limiting daytime naps, avoiding stimulants close to bedtime, and practising relaxation techniques can help achieve restorative sleep without the risks associated with medications.

Lip Health: Subtle Signs That May Point to Heart Problems
While lips are often admired for beauty, they also serve as important indicators of internal health. Experts suggest that changes in lip colour, texture, or hydration can signal more than just surface-level problems—they may reveal deficiencies, infections, or even cardiovascular concerns. Healthy lips are typically smooth, soft, and pink, reflecting proper circulation, hydration, and nutrition. When this balance is disrupted, it may point to underlying health issues that need attention. How Lip Changes Reflect Internal Health Medical professionals emphasise that lips, much like skin and nails, reflect the body's overall state.
