The reason for weight gain isn't always as obvious as inactivity or a poor diet. Weight gain can stem from many other causes. For example, it might reflect age-related physiological changes such as muscle loss, poor sleep, or changes in sex hormone levels; underlying conditions such as diabetes or sleep apnea; side effects from taking certain medications, such as antidepressants or beta blockers; or possibly the effects of eating late at night or the makeup of gut bacteria. Recent or excessive weight gain warrants a visit to a doctor to help pinpoint the issue.

Naps can be healthy for adults who need to catch up on sleep or work odd hours, but they can also make it more difficult to sleep at night and be a sign of a sleep disorder. Naps should be short and limited to the early afternoon to prevent them from interfering with nighttime sleep. People who have the urge to nap daily should consider whether they need to improve their nighttime sleep habits.

A new study found that eating an unhealthy diet high in processed food can affect people's deep sleep, the stage when the pituitary gland in the brain releases hormones to build and repair muscles and bones as well help boost cognitive function and memory.

Headaches can have many triggers from allergies to stress, or even hunger. Understanding headache triggers can help you avoid one in the future. Here's a look at the most common triggers for each kind of headache.

Neck pain is often the result of strained neck muscles that become irritated from everyday activities. Examples include watching TV for hours at a time, sleeping without enough neck support, slouching, looking down at a smartphone for long periods, lifting heavy dumbbells, or getting stressed out. Ways to avoid such neck pain include using pillows to better support the neck on a couch or in bed, sitting up straighter, keeping electronic screens at eye level, lifting weights that aren't too heavy, and practicing stress management.

Drinking coffee does not appear to increase the risk of heart rhythm problems, such as atrial fibrillation, in healthy people. It may temporarily raise blood pressure and the number of non-harmful skipped beats. While it may have other minor mixed positive and negative effects on other heart-related factors and behaviors (such as increased daily step counts, but decreased sleep duration and slightly higher LDL cholesterol), moderate coffee consumption appears to have no impact on the overall risk of cardiovascular disease.

Research supports the health benefits of taking afternoon naps, but they should last less than 30 minutes, according to a 2023 study.

A 2023 study suggests that sleep problems such as snoring, snorting, or getting too much or little sleep can significantly raise the odds of having a stroke.

Despite social media claims, mouth taping while sleeping can prove risky, leading to hampered breathing, disrupted sleep, or skin irritation. People who can't breathe through their nose when sleeping should see their doctor to evaluate the problem.

A 2022 study suggests that sleep irregularity—night-to-night variations in sleep duration and timing (when someone falls sleep)—are linked to atherosclerosis (plaque buildup in the arteries).
