The start of daylight saving time in the spring can have a profound impact on people's well-being. Moving the clock ahead one hour can cause sleep deprivation, affect focus and concentration, and exacerbate existing problems like depression, anxiety, and seasonal affective disorder. People can lessen the effect by taking steps a week prior to the time change, such as adjusting their sleep schedule, getting more light exposure, and cutting back on caffeine and alcohol.

In November 2022, the FDA called out seven supplement companies for illegally claiming their products could treat or prevent cardiovascular disease, such as atherosclerosis or heart failure.

People with knee arthritis who don't feel ready for joint replacement can take a number of steps as they ponder the possibility. These include getting knee injections or wearing a brace to reduce pain, modifying activities (such as exercise) that aggravate knee pain, losing weight to take pressure off the knee joint, exercising more to help with weight control, seeking physical therapy, getting underlying health conditions under control, doing research about knee replacement, and talking to an orthopedic surgeon.

The human heart normally keeps a predictable pace, but occasionally you might notice a sensation that feels like your heart is racing, fluttering, or has skipped a beat. While this can be alarming, it's usually not a cause for concern.

The gut is home to trillions of microbes, collectively known as the gut microbiota, which help with digestion, manufacture certain nutrients, and release various substances that have wide-ranging health effects, including on cardiovascular health. As diet plays a significant role in the composition of the gut microbiota, people's diet can indirectly affect heart health. Following a plant-based diet that emphasizes less red meat and more fiber can support the gut and its heart-healthy benefits.

A 2022 study led to questions regarding whether colonoscopy is the best strategy to reduce the risk of death from colon cancer. But overwhelming evidence supports the procedure for lowering the risk of colon cancer and related death, and experts continue to recommend people at average risk get at least one colonoscopy beginning at age 45.

Most men will lose about 30% of their muscle mass over their lifetimes, a natural process called sarcopenia. But no matter a man's age, he can still build and maintain muscle with strength training. Strength training consists of upper- and lower-body exercises using free weights, weight machines, resistance bands, or body weight. Hiring a personal trainer who can design an individual program and teach proper exercise techniques and form is an ideal first step for beginners and those returning to exercise.

Sleep is the body's time for restoration and recuperation. It's when toxins are flushed out of the brain, tissue is repaired, muscles grow, memories are consolidated, and hormones are released. Over time, getting too little sleep or fragmented sleep impairs concentration and mood and increases the risks for many chronic diseases. It helps to try to identify and address factors that may be interrupting sleep, such as snoring bed partners, alcohol, heartburn, underlying health conditions, an uncomfortable sleeping environment, or medication side effects.
