The American Heart Association added sleep to its list of factors for cardiovascular health. The others are a healthy diet; physical activity; low levels of nicotine exposure; and healthy levels of weight, cholesterol, blood sugar, and blood pressure.

People who meet the recommended physical activity guidelines may experience the same health benefits regardless of whether they spread the exercise out over the week or do it all in one or two days.

Older adults exposed to light while sleeping at night may be more likely to have obesity, high blood pressure, and diabetes compared with adults who sleep in darkness.

Stretching the muscles that support the spine can help alleviate persistent or recurring low back pain. The muscles to stretch include the erector spinae muscles along the spine, the iliopsoas muscles connecting the spine to the lower limbs, and the abdominal muscles in the front of the body that help prop up the torso. Other muscles that support the back include those in the front of the hips, back of the thighs, and buttocks. An example of a back stretch is lying on a bed and pulling the legs close to the chest for half a minute.

Cardiac rehabilitation, which teaches heart-healthy habits coupled with supervised exercise, can help people with heart conditions prevent future problems. Some parts of the program can be done at home, delivered through a computer, tablet, or smartphone. Known as virtual cardiac rehab, this approach offers several advantages over conventional rehab, such as avoiding the time and expense of traveling to multiple sessions during the week.

Left-handers make up only 10% of the population. Despite some common beliefs, science has yet to show that left-handers have any specific advantages or disadvantages over right-handed people in terms of physical abilities, cognitive health, or longevity.

Many apps support activities that promote emotional well-being. Happiness apps feature affirmations, meditations, or gratitude journals. Exercise apps track daily physical activity or provide workouts. Meditation apps guide users through various kinds of meditation, such as mindfulness or guided imagery. Sleep apps help people track how long they sleep, and offer instruction to improve sleep hygiene—such as going to sleep and waking up at the same time each day, and avoiding food and drinks at certain times.

Harvard Medical School has created a large department dedicated to developing and teaching young scientists about the emerging field of computational medicine. This field uses new mathematical techniques to make sense of the thousands of numbers generated in experiments measuring various molecules. Analyzing such "big data" was once unimaginable. Now, scientists have the tools to do it, and to compare tissue of people with and without a disease to find out which molecules are different.

An adequate supply of primary care physicians is essential for our health care system to function properly, but it's becoming more and more difficult to find one. Rates of burnout are high among PCPs, and many are considering cutting back their work hours or leaving altogether.

Reaching and maintaining a healthy weight is a major health issue. An analysis of data from multiple studies found that when weight management interventions were delivered in primary care settings, participants lost more weight and kept it off longer.
