Risk Factors for Uterine Fibroids Among Black Women

Light at night (LAN) refers to the use of artificial or natural light during nighttime hours for visibility purposes.

 Deprato et al. (2025) reports that approximately 80% of the global population is exposed to light-polluted skies, and LAN is now considered a major environmental pollutant. Sources include streetlights, vehicles, homes, industries, and even atmospheric reflections.

LAN disrupts the body’s circadian rhythm, the internal 24-hour clock regulated by the brain’s suprachiasmatic nucleus. When artificial light interferes with natural dark–light patterns, it delays the circadian clock and sleep-wake cycle, leading to melatonin suppression, sleep disturbances, and an increased risk of various diseases (Deprato et al., 2025). Blue-rich and bright LED lights cause the most significant disruption (Deprato et al., 2025). The study reports that LAN exposure is linked to higher rates of depression, bipolar disorder, anxiety, and other severe mental disorders, likely due to circadian misalignment, sleep deprivation, and changes in brain chemicals such as serotonin and dopamine.

 Implications:

1.The findings suggest that light pollution and artificial light exposure at night are not only environmental/visual concerns but also have mental health implications.

2. Encourages rethinking nighttime habits — including screen use before bed, bedroom lighting, blackout curtains, and managing exposure to streetlights or indoor lights at night.

3.The implications of light at night may vary by culture or by groups

4. Designing homes and neighborhoods that minimize intrusive nighttime lighting in bedrooms, promoting lighting standards that consider human health

Prevention/ Mitigation strategies

1.Reduce screen time before bed: Use “night mode” or blue-light filters on devices, dim the brightness, and avoid stimulating content.

2. Improve bedroom lighting: Use blackout curtains, turn off or dim indoor lights, remove bright electronic indicators, and opt for warm, low-intensity lighting in the evening.

3. Maintain a consistent sleep–wake schedule: Even if artificial light is present, a regular circadian rhythm helps mitigate disruptions.

4. Use lighting design for sleep: In the evening, switch to warmer (red/orange) wavelengths; avoid bright overhead white/blue light late at night.

5.Monitor and adjust ambient outdoor lighting: If streetlights are intrusive, consider using blackout curtains or an eye mask; if indoor lighting spills into the night, turn off non-essential lights.

Postpartum depression (PPD) is characterized by a major depressive episode that begins within four to six weeks following delivery, as per international diagnostic criteria. Recurrence rates for PPD are high, with 40% of affected women experiencing depression again in their lifetime and nearly 50% facing another episode in subsequent pregnancies. Symptoms of PPD encompass fatigue, irritability, anxiety, lack of pleasure, feelings of helplessness, sleep and appetite disturbances, indifference towards life events, low self-esteem, and feelings of incompetence as a parent, among others. PPD is considered a multifactorial condition influenced by both environmental and genetic risk factors for depression.

Risk factors for PPD  include:

• Previous depression.
• Adverse life events.
• Lack of social support.
• Socioeconomic position.
• Personal and family psychiatry history.
• Stressful experiences (such as trauma).
• Specific pregnancy-related factors.
• Intimate partner violence (IPV) occurring close to or during pregnancy also elevates the risk of postpartum depression.

The impacts of PPD are significant and extend beyond the affected individual. They include poor attachment between the mother and newborn, potential stunted growth and low weight in the child, disrupted breastfeeding, and adverse effects on the infant’s cognitive, emotional, and social development. There is also an increased risk for psychiatric disorders in the child during infancy, childhood, adolescence, and adulthood. Women of color and those with lower incomes are more likely to suffer from postpartum depression and may face barriers to accessing treatment (Gopalan et al., 202).

The four-stage process to regain control of Postpartum Depression

Women experiencing PPD often undergo a four-stage process in an attempt to regain control:

1. In the initial stage, mothers grapple with intense worries, persistent obsessive thoughts, and difficulties focusing.
2. In the second stage, women feel a sense of loss of their “regular selves,” describing a robotic feeling while caring for their infants. Withdrawal may occur, and thoughts of self-harm or suicide may surface.
3. The third stage involves women planning strategies to overcome PPD, such as seeking help from healthcare providers, engaging in prayer, or finding comfort in support groups.
4. In the final stage, women regain control of their thoughts and feelings as despair lifts.

Coronary Heart Disease (CHD) is a chronic and intricate ailment associated with substantial morbidity and mortality, primarily attributed to atherosclerotic lesions in coronary vessels, ultimately leading to myocardial infarction (MI) and stroke. Unhealthy eating habits, often influenced by chronic inflammation, are closely linked to CHD. Various health conditions, lifestyle choices, as well as your age and family history, can elevate the risk of developing heart disease; approximately 47% of Americans have at least one of the three primary risk factors for heart disease: high blood pressure, elevated cholesterol levels, and smoking. Certain risk factors for heart disease, such as age or family history, are beyond your control. However, you can proactively reduce your risk by changing the factors you can control.

Behaviors that heighten the risk for heart disease are

• Smoking: The Food & Drug Administration (FDA) estimates that cardiovascular disease causes 800,000 deaths and 400,000 premature deaths per year. About one-fifth and one-third of these result from smoking, respectively. Additionally, research reported that smoking resulted in a 51% increased risk of coronary heart disease in patients with diabetes. Cigarette smoking has the potential to harm the heart and blood vessels, amplifying the risk for heart conditions like atherosclerosis and heart attacks. Even nonsmokers face an increased risk of heart disease when exposed to secondhand smoke.
• Excessive alcohol consumption can elevate blood pressure and elevate the risk of heart disease. It also leads to increased triglyceride levels, a fatty substance in the blood associated with an elevated risk of heart disease.
• Sedentary lifestyle: Insufficient physical activity is a precursor to heart disease and can strengthen the likelihood of other medical conditions that serve as risk factors, including obesity, high blood pressure, high cholesterol, and diabetes. Engaging in regular physical activity can effectively decrease the risk of heart disease.
• Unhealthy Eating Habits: A diet rich in saturated fats, trans fats, and cholesterol has been associated with heart disease and related conditions like atherosclerosis. Recent research has provided more explicit evidence that trans-fat significantly raises the risk of cardiovascular disease by adversely affecting lipids, endothelial function, insulin resistance, and inflammation. For each 2% increase in calories consumed from trans-fat, there is a 23% higher risk of coronary artery disease. Recent studies and systematic reviews have focused on red and processed meat consumption. The research consistently demonstrates an increased risk of coronary heart disease and cardiovascular events. The risk ranges from 15% to 29% higher with red meat consumption and 23% to 42% higher with processed meat consumption

Measures for Reducing the Risk of Coronary Heart Disease

•  Educating children and adolescents about the dangers of smoking to deter the initiation of tobacco use. The Food & Drug Administration (FDA) reported that the risk of coronary artery disease decreases to the level of lifetime nonsmokers within four years of quitting and within ten years. 
• The DASH, Mediterranean, and vegetarian diets have the most evidence for cardiovascular disease prevention. The DASH diet has been shown to lower systolic blood pressure by up to 11.5 mmHg in adults with hypertension. Additionally, reported findings indicate a 21% reduction in coronary artery disease risk with adopting the DASH diet.
•  The American Heart Association suggests substituting saturated fat with polyunsaturated and monounsaturated fats. A 5% shift from saturated fat to polyunsaturated fat consumption is linked to a 10% lower risk of coronary artery disease.
• Engaging in about 150 minutes per week of moderate-intensity aerobic activity significantly lowers the risk of cardiovascular disease. Moderate-intensity aerobic exercise is characterized by activity that maintains a heart rate between 50 to 70 percent of the individual’s maximum heart rate, calculated as 220 beats per minute minus the person’s age.

Postpartum depression (PPD) presents a significant public health concern, affecting not only the physical and mental well-being of mothers but also that of their infants. Research suggests that approximately 13 million women worldwide are diagnosed with PPD annually (Xu et al., 2023). Mild depressive symptoms are experienced by around 50% to 75% of mothers, with 10% to 15% developing postpartum depression within the first week after childbirth (Xu et al., 2023).

Understanding preventive measures to reduce its prevalence is very crucial.

 1. Exercise intervention has proven effective in preventing PPD disorders. In a 12-week exercise intervention study, aerobic exercise was found to relieve postpartum depression symptoms in PPD patients. Engaging in suitable aerobic exercise during pregnancy has been reported to promote pelvic mobility and improve birth canal space to relieve maternal labor pain. However, it also aids in preventing pregnancy complications. Studies suggest that PPD symptoms may manifest during pregnancy, with a similar 12% occurrence rate of depression reported, which indicates that preventive measures during pregnancy may have a significant impact on reducing PPD (Xu et al., 2023).

Moreover, research indicates that the antidepressant effects of exercise can persist beyond the cessation of physical activity. Therefore, research suggested that incorporating aerobic exercise into prenatal care may substantially prevent PPD more than exercise as a postpartum treatment strategy.

Engaging in moderate exercise during pregnancy can reduce the likelihood of developing postpartum depression (PPD) among expectant mothers. Partaking in at least 150 minutes of moderate-intensity aerobic exercise per week significantly enhances the efficacy of physical activity in preventing and treating PPD (Xu et al., 2023). Moderate aerobic exercise prompts the release of endorphins, which uplift mood and alleviate symptoms of anxiety and depression. Additionally, it helps regulate hormone levels, improve sleep quality, and enhance self-awareness and self-esteem, thereby positively influencing the mitigation of postpartum depression (Xu et al., 2023).

Also, social support plays a vital role in maintaining the mental well-being of pregnant and postpartum women, with supervised exercise and team-based exercise serving as effective avenues for providing such support. For instance,

• Team exercise fosters a positive environment for maternal emotional communication, and sharing maternal emotions enhances mothers’ childbirth knowledge and skills, reduces fear of labor pains, alleviates negative emotions, improves interpersonal communication, and enhances self-efficacy (Xu et al., 2023).

• Supervised exercise, which involves physical activities piloted and supervised by healthcare professionals or fitness trainers, ensuring that exercises are safe and suitable for individual pregnant and postpartum women. Participating in supervised exercise classes or programs also offers opportunities for social interaction, which is critical for mental well-being and can lighten feelings of isolation by connecting with other new mothers and professionals in a supportive setting (Xu et al., 2023).

2. Music therapy, when used as an adjunct to conventional psychotherapies, has been shown to improve physiological symptoms and effectively reduce negative emotions without any adverse side effects. It can positively impact and alleviate symptoms of PPD, offering a safe and affordable substitute to standard treatments. Music therapy is considered to reduce the need for pharmacological interventions during PPD treatment. Research has indicated that music therapy interventions such as music listening, improvisation, songwriting, singing, relaxation and meditation, and lyric analysis effectively reduce the risk of prolonged PPD and it can encourage strengths, empower individuals, and foster connections with themselves and others (Patch & Short, 2022).

Stress has a significant impact on overall health, playing a crucial role in the development of various diseases and placing a substantial strain on the healthcare system (Shchaslyvyi et al., 2024). It is closely linked to numerous long-term health problems, especially cardiovascular conditions, which are often worsened by daily psychosocial pressures like job-related stress (Shchaslyvyi et al.,2024) It is essential to understand the healthy ways to cope with or manage stress.

Various strategies recommended according to the CDC (2025)

1. Take Care of Your Mind

Limit news and social media exposure: Excessive exposure to harmful or distressing news can exacerbate stress.

Make time to unwind: Incorporate relaxation practices such as deep breathing, stretching, or meditation.

Keep a journal: Writing can help you process emotions, reflect on your thoughts, and release tension.

Spend time outdoors: Whether you are being active (walking, hiking) or just relaxing outside, nature can be a calming presence.

Practice gratitude: Regularly noting things you are grateful for helps improve emotional well-being.

Connect with others: Talking to trusted friends, family, or community/faith-based groups provides support.

2. Take Care of Your Body

Get enough sleep: The CDC recommends 7 hours or more per night for adults and suggests maintaining a consistent sleep schedule.

Move more: Physical activity is one of the most effective ways to reduce stress; even small amounts can help.

Eat well: A balanced diet (fruits, vegetables, lean proteins, whole grains, low-fat dairy) supports both physical and mental health.

Limit alcohol and avoid substance misuse: Moderating alcohol intake, avoiding illegal drugs, and not misusing prescription medication are essential.

Avoid tobacco: Smoking, vaping, and the use of other tobacco products can worsen stress or its effects.

Stay up to date with healthcare: Regular check-ups, screenings, and vaccinations help you maintain your physical health — which can help buffer stress.

3. Integrate Physical and Mental Health

The CDC emphasizes that mental well-being and physical health are closely linked. Regular physical activity is not only good for the body but also supports emotional resilience.

It encourages finding a “right combination” of coping techniques that work for you — not everyone copes the same way.

4. Know When to Seek Extra Support

The CDC notes that while stress is everyday, chronic stress (long-term) can lead to serious health problems.

If you’re struggling to cope or stress is affecting your daily life, it’s okay to reach out for help. They list resources, including crisis lines.

Our connections with family, friends, and colleagues are crucial. Individuals who have strong social connections and supportive relationships are more likely to adopt healthy lifestyles and effectively cope with stress, anxiety, and depression, especially during difficult times. A supportive network of family members, close friends, and colleagues provides a sense of belonging and emotional support.

  Ways to create meaningful impacts are;

1.Showing kindness: Providing a listening ear, checking in on them, offering assistance, or simply sharing a smile can profoundly influence the overall well-being of others.

2. Promoting physical activity: Encouraging others to participate in physical activities such as organizing sports events, walking or running together, or engaging in group activities can enhance physical and social well-being.

3. Spreading awareness and education: Educating others about healthy lifestyle choices, including proper nutrition, exercise, and stress management, can empower them to make positive life changes.

4. Promoting a healthy diet: Sharing recipes, discussing healthy eating habits, organizing cooking classes, and advocating for nutritious foods can encourage healthier dietary choices.

5. Supporting access to healthcare: Being present for others during difficult times is crucial and can significantly improve their lives. Providing transportation to healthcare facilities encourages them to seek professional help when needed, and assisting with paperwork can make access easier.

6. Advocating for policy changes: Supporting policies and initiatives that promote public health, such as mental health services, water regulation, and access to healthcare, can have a broad impact on the well-being of entire communities.

7. Assisting those with chronic illnesses: Offering understanding and support to individuals with chronic health conditions can help them manage their conditions and enhance their quality of life.
