People who take between 3,800 and 9,800 steps daily may reduce their risk for dementia, and walking at a brisk pace could offer even more protection, according to a 2022 study.

As people age, they are more likely to explore a religious or spiritual practice. Research has found that this type of engagement is linked to longer life and a lower risk of serious health issues. These practices also can offer comfort and support if and when a person needs to navigate difficult times.

While a man cannot directly give his female partner a bladder infection, he can increase her risk with vigorous or frequent sexual intercourse.

An enlarged thyroid, called a goiter, or nodules on the gland are quite common, especially in women. Doctors pat down the neck during physical exams to help detect these conditions. Treatment depends on whether a lesion is cancerous or causing severe symptoms. Some goiters or nodules are simply monitored over time.

Several problems can block the passages on one or both sides of the nose. For example, allergies can inflame sensitive tissue inside the nose, reducing the space left for air to flow through nasal passages; a crooked wall (septum) separating the passages of the nose can block airflow, making it hard to breathe; and aging can cause tissues in the nose to sag, which can narrow nasal passages. Strategies to open nasal passages depend on the cause of obstruction. Treatments range from using nasal sprays to widening nasal passages with surgery.

Concussions occur when the brain bumps or twists inside the skull after a blow to the head. Signs of concussion include headache, eye pain or fatigue, neck pain or stiffness, imbalance, impaired depth perception, difficulty remembering, or sleep pattern changes.

Gout strikes when too much uric acid builds up in the body and triggers severe pain, swelling, and redness in one or more joints, often in the big toe. New research suggests that an episode may increase the risk for a heart attack or stroke over the following two months.

Many medications can affect sleep. These include prescription drugs as well as over-the-counter remedies. For example, decongestants, certain antidepressants, or beta blockers can make it hard to fall or stay asleep, and nicotine replacement medications can cause a person to have nightmares. Strategies to avoid drug-related sleep problems include taking the medication during the day, taking a lower dose, practicing good sleep hygiene (such as going to bed and waking up at the same time each day), or switching to a new medication.

People with attention-deficit hyperactivity disorder, a condition marked by trouble focusing and impulsive behavior, may be more likely to have cardiovascular disease that people without the disorder.

Genes that helped people survive during the time of the Black Death are more likely to be found in people with autoimmune diseases alive today. Does this tell scientists anything about what surviving the COVID-19 pandemic might mean for the world's population?
