February is a month to celebrate matters of the heart—both in love and in health. With Valentine’s Day and American Heart Month, February is the perfect time to cherish our loved ones while committing to a heart-healthy lifestyle. Heart disease is the leading cause of death in the United States, accounting for 1 in 5 deaths in 2022, according to the CDC. By understanding the risks and taking proactive steps, we can build healthier lives, families, and communities.
Heart Disease Defined

So, what is heart disease? The term “heart disease” actually refers to several conditions affecting the heart, but the most common is coronary artery disease (CAD). CAD occurs when deposits of Low-Density Lipoprotein (LDL), “bad” cholesterol, and other substances form plaque in the arteries. Over time, this plaque buildup can narrow the arteries, restricting or blocking blood flow.
Other types of heart diseases include arrhythmias (abnormal heart rhythms), cardiomyopathy (abnormal heart muscle), heart valve disease, and heart failure. Understanding these conditions is essential to recognizing potential and current risk factors and acting.
Knowing Your Risks & Making Changes
When it comes to heart health, some risk factors are beyond our control, such as genetics and age. These elements are woven into the fabric of who we are, making them difficult—or impossible—to change. However, lifestyle choices, such as diet, physical activity, smoking, and even some environmental factors can be changed at the individual level. In the United States, nearly half of the population has at least one of these three key risk factors for heart disease:
- Hypertension (High Blood Pressure)
- High LDL Cholesterol
- Smoking
Lifestyle changes—such as improving your diet, staying active, and avoiding smoking—can make a significant difference. Taking care of your heart is much like nurturing a great relationship. It begins with small steps and grows stronger with consistent care, dedication, and some compromises. Your daily decisions about food, exercise, and habits like alcohol and tobacco use play a starring role in your heart health. While you can’t change your genetics, the choices you make today can lead to a healthier tomorrow.
Share the Love
Show your loved ones you care by encouraging heart-healthy habits. Plan an active date, such as a scenic nature walk or a fun bike ride, or cook a delicious and nutritious meal together. Celebrate the month of love by taking charge of your heart health and inspiring others to do the same.
Whether it’s making small changes to your routine, learning more about heart disease, or supporting awareness efforts, every step counts toward a healthier, happier future for you and those you love. Let’s make February a heartfelt celebration of love and health.

January is recognized as National Blood Donor Month, but what makes blood and blood donation so important?
What is blood?
Blood is an essential bodily fluid that constantly flows through your body keeping it working. It has four main components: red blood cells, white blood cells, plasma, and platelets. Each part is designed to specific tasks.

Plasma
The majority of blood—approximately 55%—is composed of plasma. It is yellowish fluid that is a mixture of water, sugar, fats, proteins, and salts. Its main task is to transport blood cells throughout the body, but is also moves products like nutrients, proteins, hormones, and waste.
Red Blood Cells
The second largest component in blood is red blood cells (RBCs), or erythrocytes, making up about 40 – 45 percent of its total volume. These cells contain a protein called hemoglobin, which helps carry oxygen from the lungs to the rest of the body. Hemoglobin also gives RBCs, and the rest of the blood, their distinct red color.
White Blood Cells
White blood cells, or leukocytes, make up a much smaller portion than red blood cells about 1% of the blood. Their role is to protect the body from infections.
Platelets
Unlike red and white blood cells, platelets are not actually cells, but rather fragments of cells. They are the small component within blood being less than 1% of the total volume of blood. Platelets manage bleeding by assisting in the blood clotting process (coagulation) to seal damaged blood vessels to prevent a large amount of blood loss.
What are the blood types?
Blood also contains antigens, and a protein called the Rh factor, which serve as markers that determine a person’s blood type. Based on antigens alone, there are four main blood types: A, B, AB, and O. However, the Rh factor further classifies blood as either positive (+) or negative (-), resulting in a total of eight common blood types: A positive (A+), A negative (A-), B positive (B+), B negative (B-), AB positive (AB+), AB negative (AB-), O positive (O+), and O negative (O-). The most common blood type, in the United States, is O positive (O+); the least common, in the United States, is AB negative (AB-).
| Blood Type |
Approximate U.S. Population Percentage |
| A positive |
33% |
| A negative |
6% |
| B positive |
9% |
| B negative |
< 2% |
| AB positive |
< 4% |
| AB negative |
< 1% |
| O positive |
38% |
| O negative |
7% |
Understanding blood types enables healthcare providers to safely perform blood transfusions and organ transplants by ensuring compatibility between the donor and the recipient. Additionally, those with AB positive (AB+) blood are known as universal recipients; those with O negative (O-) blood are universal donors.
What’s the importance of blood donors?
According to the American Red Cross, someone in the United States needs blood and/or platelets every two seconds. That is about 29,000 units of red blood cells, 5,000 units of platelets, and 6,500 units of plasma needed daily. Nonetheless, there is no substitute or manufactured version for blood, which means it has to be generously donated by volunteers. It is important for surgeries, cancer treatment, childbirth, chronic illnesses (e.g., sickle cell disease), and traumatic injuries (e.g., car accidents). For more information on the donation process and how to prepare for a donation check out this website from the U.S. Department of Health and Human Services (HHS).
To the almost 7 million people in the United States who donate their time and blood, thank you. Your single donation has saved multiple lives, and your generosity is worth celebrating.

Thanksgiving, like other holidays, promises gratitude and togetherness, but it can also bring stress, awkward moments, and even indigestion. As family members gather – from near and far – to share a meal, navigating conflicting personalities, differing opinion, and the drive for perfection can make hosting feel daunting. To help ensure a peaceful (and maybe even enjoyable) holiday, here are a few Thanksgiving dos and don’ts.
DOs
- Set Realistic Expectations. While many dream of a picture-perfect Thanksgiving, real life is rarely like a cheesy holiday movie. Accept that things might not go as planned, and those imperfections are perfectly fine. Instead of pursuing perfection, aim for a day where everyone has moments of enjoyment, even if brief.
- Plan Ahead. Hosting Thanksgiving can be overwhelming—you’re the cook, cleaner, and event planner all in one. Schedule tasks into manageable chunks over the course of a few days, prepping dishes in advance, and delegating responsibilities. Ask your guests to bring sides – this lightens your load and involves them in the holiday prep.
- Choose Your Seat Wisely. Sit near family members you get along with. If you’re arranging seating, separate personalities likely to clash to keep the atmosphere peaceful.
- Take Care of Yourself. Schedule time for yourself before, during, and after Thanksgiving. It can be a short walk, meditating, or a quick and quiet escape to play a video game or watch a movie. If you are unable to leave a stressful situation, calm yourself with five slow, deep breaths.
- Learn to Let Things Go. Family quirks and annoyances are part of the package. Practice patience and remember, it’s just for a short time.
- Remember the Reason for the Season. Reflect on or share what you are thankful for—whether it’s a good meal, health, a roof over your head, or time with loved ones. Focusing on gratitude can be a great tool to shift the mood toward positivity.
DON’Ts
- Dominate the Conversation. Thanksgiving is for catching up with friends and family, not just talking about yourself. Be mindful, and make space for others to share, especially if it’s been a while since you have seen them.
- Try to Fix Problems. Now is not the time for unsolicited advice or life coaching. One conversation over what is supposed to be a happy meal won’t mend a marriage, convince someone to start a family, make someone a better parent, or get them to hit the gym.
- Discuss Sensitive Topics. Subjects like politics, religion, or lifestyle choices are best left off the dinner table. Even well-meaning questions like “When are you getting married?” or “When can I expect grandchildren?” may seem innocent but can make people uncomfortable. Stick to lighter topics that bring people together, such as favorite family traditions, upcoming plans, or funny memories from past Thanksgivings, this helps create a positive, welcoming environment for everyone.
- Drink Excessively. Some people become argumentative or aggressive when drinking, which can escalate tensions. Avoid these individuals if they get rowdy, and prevent them from driving. If this is an issue for you, consider mocktails or non-alcoholic drinks.
Thanksgiving does not have to be a stressful situation. By prioritizing your well-being and keeping gratitude at the forefront of the celebration, you can make Thanksgiving a meaningful, enjoyable day—flaws and all.

As leaves change color and days grow shorter, seasonal depression can start affecting some individuals. Seasonal Affective Disorder (SAD), a type of depression with seasonal patterns, often begins in young adulthood and becomes more likely with age, especially for those aged 18 to 30. An estimated 5% of adults in the U.S. experience SAD, with higher rates among people assigned female at birth. Risk factors include having another mood disorder, family history of SAD or other mental health conditions, living far from the equator, or residing in cloudy regions, all of which can increase susceptibility. There are two types of SAD: winter depression and summer depression. Winter depression occurs during the late fall to early winter months. Summer depression is less prevalent, with symptoms starting in late spring to early summer.
Seasonal Depression Symptoms
- Sadness
- Anxiety
- Feeling hopelessness
- Difficulty concentrating
- Increased appetite and weight gain
- Fatigue
- Social withdrawal
- Loss of interest in pleasurable activities
- Issues with sleeping (oversleeping)
- Irritability
- Thoughts of suicide or death
Those who experience summer seasonal depression may also experience:
- Insomnia
- Decreased appetite
- Violent outbursts
While the exact cause of seasonal depression remains unclear, several theories link it to reduced sunlight and shorter winter days. Shorter days disrupt the body’s internal clock, or circadian rhythm, which affects mood, sleep, and hormone levels. Neurotransmitters, brain chemicals, including melatonin and serotonin, can become imbalanced. As winter brings longer periods of darkness, melatonin (a sleep-related hormone) increases, which may may contribute to sluggishness and fatigue. Sunlight and vitamin D help stimulate the production of serotonin (a mood-related hormone); therefore, vitamin D deficiency and reduced sun exposure can impact serotonin levels and mood. Additionally, those with SAD may also experience negative thoughts associated to the season, though it’s unclear if these thoughts are a cause or a result of the condition.
If you’re experiencing symptoms of Seasonal Affective Disorder (SAD), consult your healthcare provider for an evaluation. They may refer you to a mental health professional, as SAD can sometimes be part of a broader mental health condition. Additionally, if you or someone you know is struggling with thoughts of suicide or needs immediate help, dial 988 for free, confidential support.

September is National Sickle Cell Awareness Month, designated by Congress to highlight the need for research and treatment of sickle cell disease (SCD). The Centers for Disease Control and Prevention (CDC) defines SCD as a group of inherited red blood cell disorders that affect the hemoglobin, the iron-rich protein that carries oxygen. Normal red blood cells are disc-shaped and flexible, allowing them to move through blood vessels easily. However, due to the genetic mutation, the red blood cells have transformed into a crescent or “sickle” shape that are hard and sticky. These sickle-shaped red blood cells can clog small blood vessels, disrupt blood flow and cause pain and serious health issues such as deep vein thrombosis, stroke, and organ damage.

Sickle cell disease is inherited when a person receives one or two genes for the abnormal hemoglobin S, one from each parent. People with only one abnormal hemoglobin S gene and a normal hemoglobin gene have sickle cell trait (HbAS) and typically do not show signs of the disease. Other abnormal hemoglobin genes, such as “C,” “D,” “E,” or “O,” can also be inherited alongside the hemoglobin S, often resulting in milder forms of SCD. The most severe form, sickle cell anemia (HbSS), occurs when a person inherits two abnormal hemoglobin S genes. In the United States, one to three million people have the sickle cell trait, and more than 100,000 people have SCD, many of whom are of African descent or identify as Black. Globally, about two million people have SCD, and over 100 million carry the trait. SCD also affects individuals of South Asian (specifically Indian), Hispanic, Middle Eastern, and Southern European ancestry.
Sickle cell disease can be detected at birth through routine screening, with symptoms typically appearing around six months of age. These can range from mild to severe and include anemia, pain crises, swelling in extremities, infections, delayed growth/puberty, and vision problems. Although SCD is a life-long disease, there are treatments available to manage symptoms and improve quality of life. A bone marrow transplant was previously the only cure, but two new gene therapies approved by the FDA in December 2023 offer additional treatment options. Other treatments such as medication and blood transfusions can also help reduce symptoms and prolong life.
Individuals, particularly those with a family history of sickle cell disease or from high-risk populations, may consider seeking a genetic counselor; understanding their carrier status can help them make informed family planning decisions. When both parents have the trait, each pregnancy has a 25% chance of resulting in a child with sickle cell anemia. If only one parent has the trait, there is a 50% chance that the child will inherit the sickle cell trait. Historically, individuals with sickle cell anemia rarely lived past the age of five. Today, advances in modern medicine have extended life expectancy into the fifties, though this remains significantly lower than the average life expectancy. That is why this month is important. Increasing awareness about SCD is essential for increasing research and its funding, improving treatment options, and supporting those affected.
