The Impact of a Healthy Lifestyle on Psychological Well-Being

A healthy lifestyle encompasses healthy eating, regular exercise, getting enough sleep, and avoiding smoking, drug abuse, and alcohol, which will help improve mental health and manage the symptoms of anxiety, stress, and depression.

 How can a healthy lifestyle help?

A healthy lifestyle may help prevent the onset or worsening of mental health conditions. Several aspects of a healthy lifestyle can improve mental health, including changes in diet and physical activity. Some helpful resources outlining healthy eating choices and changes were featured in the March The ONE Group blog outlining National Nutrition Month.

How does exercise help?

Getting the recommended amount of exercise can lead to beneficial changes in mood, anxiety and depression.

Exercise improves mental health by reducing anxiety, stress, depression and negative mood, and by improving cognitive function. Muscle-strengthening activities should be included in an exercise routine, twice a week. This includes yoga, strength training with free weights, resistance band exercises and bodyweight exercises such as pushups, lunges and squats. Aerobic exercises, such as walking, gardening, swimming, running and cycling, have been shown to reduce anxiety and depression. One to two hours of exercise per week have been shown to reduce the risk of depression.

Does exercise need to be structured or long?

No! You don’t need a gym membership to make exercise a part of your life. Try an exercise snack! What is that? Exercise snacks are a few minutes of activity dispersed throughout the day. 

How do I get started?

Living a healthy lifestyle isn’t always easy, especially during these unique times. Remember, small changes are all you need. Gradually making small changes – like going for a walk, doing an exercise snack or choosing healthier options – can go a long way to ensuring that you focus on regularly adding exercise to your life.

Health benefits of regular exercise

Regular exercise can have profound effects on several aspects of mental health, including:

  • Improved sleep
  • Improvement in mood
  • Prevention or reduction of depression
  • Stress relief
  • Increased energy and stamina
  • Increased mental alertness and cognitive function

Health is important to all of us. According to the World Health Organization (WHO), health is a state of complete physical, mental, and social well-being and not just the absence of disease or infirmity. There are different types of health: mental, physical, spiritual, emotional, and financial. All of these contribute to overall health, decrease stress, and improve mental and physical well-being. Healthy nutrition does not mean tasteless food; on the contrary, it is a method to ensure eating all essential nutrients to maintain the body's function properly. The definition of a balanced diet varies from person to person and depends on many factors like age, gender, lifestyle, and medical conditions. Following a balanced and healthy eating lifestyle keeps the body in excellent and optimum condition. When it comes to nutrition, there are macronutrients and micronutrients. The "big 3" macronutrients (macros) are carbohydrates, protein, and fats; fiber can also be considered a macronutrient. These macronutrients can help improve weight, health, and overall physical well-being.

Carbohydrate is an essential source of energy. It is classified into simple (sugar) and complex starches. Carbohydrates from grain are classified into whole and refined grain; it is healthier to eat whole grain because it has a milder effect on blood sugar and insulin than refined grains. The recommended dietary intake of carbohydrates is 45-65% of the total calorie intake. Added sugars should constitute less than 10% of total calories. Protein is an essential part of a healthy diet. It helps build muscles, cartilage, and skin and also plays a role in hormonal regulation. The recommended dietary intake of proteins is 10-35% of the total calorie intake. Fat is also an essential part of a healthy balanced diet. It helps the body to absorb fat-soluble vitamins like vitamin A, vitamin D, vitamin E, and vitamin K. Also, fat is a rich source of energy. There are three types of fat: saturated, unsaturated, and trans-fat; as part of maintaining a healthy diet, it is advisable to replace saturated and trans-fat with unsaturated fat. The recommended dietary intake of fats is 20-35% of the total calorie intake. Fibers are found mainly in fruits, vegetables, whole grains, and legumes. Fibers provide a lot of benefits; they help prevent and relieve constipation, help maintain a healthy weight, and lower the risk of diabetes, heart disease, and some types of cancer. There are two types of fibers: soluble and insoluble. Soluble fiber helps lower cholesterol and glucose levels. Insoluble fibers help to relieve and prevent constipation. The recommended dietary intake of fiber is 14 g per 1000 calories. For most moderately active adults in the United States, that translates to approximately 25-36 g per day. Micronutrients include vitamins and minerals. These nutrients are indispensable for numerous vital functions in the human body and it is necessary to consume them through dietary sources.

Physical activity is defined as any body movement produced by skeletal muscles that requires energy expenditure. Regular physical activities confer a lot of health benefits. They help to prevent and manage non-communicable diseases like cardiovascular disease, hypertension, diabetes, and several types of cancers. They help to maintain a healthy body weight and improve mental health and quality of life. The recommended physical activity for an adult involves 150-300 minutes of moderate-intensity aerobic exercise or at least 75-150 minutes of vigorous-intensity aerobic exercise, or an equivalent combination of moderate- and vigorous-intensity exercise regimens throughout the week. They should also perform muscle-strengthening activities that involve all major muscle groups two or more days a week. For children and adolescents aged 5-17 years, the recommended physical activity involves at least 60 minutes per day of moderate-to-vigorous intensity, mostly aerobic, exercise across the week.

  Mental health promotion is the ‘mental health’ component of health promotion. It is “the process of enabling people to increase control over their mental health and its determinants, and thereby improve their mental health.” Mental health promotion focuses on helping people to acquire the knowledge and skills they need to promote and protect their own mental wellbeing, while simultaneously working to create positive changes in our shared social environments that promote our collective mental wellbeing.

Mental health promotion is different from, but complementary to mental healthcare. It focuses on influencing underlying root causes rather than managing specific conditions. It targets whole group...

Lifestyle choices and mental health + Conclusion

Image
A healthy mental state is essential for all learners to thrive in school and in their daily lives. Positive mental well-being lies on a continuum along which individuals shift in relation to life stressors and biological and psychological factors. While these shifts occur at every stage of human development, children and adolescents are especially vulnerable to the detrimental effects of poor mental health as it can affect their social relationships at school, their identities, their academic progress and later life chances. Social and emotional learning programmes offered at the school level are effective at promoting positive mental health, but more important, are school staff who are knowledgeable about and responsive to students’ mental health states. At the individual level, teachers and guidance counsellors are best-placed to assist learners with recognising mental health as a priority. This book, authored by post-graduates with a deep understanding and intimate experience of sc...
