Better Sleep and Cleaning hands with soap or alcohol
Lack of sleep has adverse effects on the immune system and therefore you should have sufficient sleep. Adequate sleep supports your immune system so that it can be much more effective in fighting viruses and germs. Several studies reinforce that keeping your hands clean is one of the best ways to reduce the spread infectious diseases like COVID-19.
If soap and water are not available, using hand sanitizer with minimum of 60% alcohol. For more check link: https://healthylivinguru.com/ultimate-guide-to-boost-immunity-against-covid-19-infection/

Using alcohol-based hand sanitizers is preferable to washing hands with soap and water. Dry off your hands completely.
