Taking a break and relaxing is good for your body. However, don’t be too relaxed that you become lazy or don’t be too active that you exhaust your body. This will weaken your body and might cause illness. You can try to stay fit with light exercise every day.
You should also take care of hygiene during this period. Keep clean with frequent hand washing, and sanitizing. This will minimize the spread of infection and illness causing bacteria.
If you have any type of allergies including dust or pollen allergy then try to keep the air in your home fresh and use masks and nasal spray.
Have some gut friendly foods including Curd and fermented food to improve immunity by strengthening the gut bacteria. You can also take some vaccines to prevent common seasonal infections.
