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.

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.

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 2023 study suggests that women who practice many aspects of a healthy lifestyle are about half as likely as women who don't to experience persistent symptoms after a COVID-19 infection.

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).

Obstructive sleep apnea is a condition marked by brief pauses in breathing, often triggering loud snoring, grunts, gasps, and choking noises. Because sleep apnea can put stress on your heart and circulation, it's important to learn the signs and symptoms and get treatment.

A 2022 study found that people with sleep apnea are more likely to have low bone density. Apnea may trigger low oxygen levels and inflammation that impair the body's continuous bone renewal process.

Napping for  more than 30 minutes each day may be associated with increased risks for health problems. Causes of excessive napping include boredom, poor sleep at night, underlying conditions such as anemia or depression, medication side effects, dehydration, or malnutrition. Treating underlying conditions, staying hydrated, eating a healthy diet, becoming more active, and practicing good sleep hygiene may help reduce prolonged nap times.

Taking regular afternoon naps for less than 60 minutes can improve mental alertness and increase productivity.

There’s no evidence that maintaining a healthy lifestyle will suddenly boost the immune system. However, it’s clear that healthy lifestyle habits contribute to overall health, supporting the body’s ability to fight infections instead of creating new problems. Healthy habits that help maintain a robust immune system include getting seven to nine hours of sleep per night, exercising, reducing stress, eating a healthy diet, not smoking, drinking alcohol only in moderation, maintaining a healthy weight, and getting underlying conditions under control.
