Self-defense is the best defense. To protect ourselves from any disease or infection we need to increase our immunity. How can we do that? It is relatively simple and inexpensive. What we need is our desire and a bit of modification of our lifestyle and food habit.
Adequate rest and sleep are important to increase our immunity. At least 6 to 8 hours of sleep at night is recommended for adults. It refreshes the body and mind and enhances immunity. Reduce stress by praying, exercise, meditation and yoga. Less stress will result in peace and will lead to more immunity.
Healthy foods are closely linked to increased immunity. A balanced diet is needed to keep the body and mind strong and healthy. Food consists of macronutrients and micronutrients. Macronutrients mean carbohydrates, proteins, fats and water - adequate intake of these are important for growth and development. Micronutrients mean vitamins and minerals which are also essential for life. They cannot be synthesised in the body, thus to be taken with food. Less sugar and salt consumption always help us to remain healthy and fit.
We all know that there is no vaccine or specific medication for COVID-19 until now. It can only be prevented by maintaining proper health and hygiene practices like social distancing, frequent hand washing and wearing masks whenever required etc.
If someone is infected with COVID-19, the most important remedy is mental strength and one's immunity. With strong morale and good immunity, one may overcome the problem easily.
