The Science Behind How to Be Healthy


We all want to be healthy, but sometimes it seems like an impossible task. Between fad diets, conflicting advice, and the constant barrage of health trends, it can be hard to know what's actually good for us. That's why we looked to science to find out the truth about how to be healthy. In this post, we'll break down some of the most important scientific studies and what they can tell us about living a healthy life.


1. Physical activity - One of the biggest factors in overall health is physical activity. A study published in the Lancet found that people who were more physically active had a significantly lower risk of cardiovascular disease, diabetes, and some types of cancer. The study also found that even small increases in physical activity can make a big difference. Aim for at least 30 minutes of moderate exercise a day, like brisk walking or cycling, to help keep your body healthy.

2. Sleep - Sleep is another important aspect of a healthy lifestyle. Lack of sleep has been linked to a range of health problems, from obesity to depression. A study published in the Journal of Sleep Research found that people who slept for less than six hours a night had a higher risk of premature death. Aim for seven to eight hours of sleep a night to keep your body functioning at its best.

3. Nutrition - Eating a balanced, healthy diet is crucial for good health. A study published in the New England Journal of Medicine found that people who followed a Mediterranean-style diet had a significantly lower risk of heart disease, stroke, and overall mortality. The diet includes plenty of fruits, vegetables, whole grains, and healthy fats, like those found in fish and nuts. Avoid processed foods, sugary drinks, and excessive alcohol consumption to keep your body healthy.

4. Stress Reduction - Chronic stress is linked to a range of health problems, from high blood pressure to digestive issues. A study published in the Journal of Alternative and Complementary Medicine found that mindfulness meditation can help reduce stress and improve overall health. Try setting aside a few minutes each day for quiet reflection or practicing meditation to help reduce your stress levels.

5. Social Connections - Our social connections are also a vital part of our overall health. A study published in the American Journal of Public Health found that strong social connections were linked to a lower risk of premature death and a range of chronic diseases. Make time to connect with friends and family, join a community group, or volunteer to help keep your social connections strong.


When it comes to being healthy, science has a lot to say. Physical activity, sleep, nutrition, stress reduction, and social connections are all key factors in overall health and wellbeing. By incorporating these habits into your daily life, you can help keep your body healthy and functioning at its best. Remember, small changes can make a big difference, so start with one or two habits and build from there. Here's to a healthy, vibrant life!
