Staying at home, proper personal hygiene, eating right, and social distancing certainly help a lot in "flattening the curve" and containing the coronavirus threat across the world. However, at some point you might have to go outside, either to restock on home essentials or to engage in limited outdoor exercises. Whatever you do, it is best to keep yourself hydrated along the way.

Hydration helps in keeping your immune system strong, which helps your body fight effectively against viruses and diseases. According to the healthcare company Abbott, your body needs fluids and electrolytes to function at its best, and that proper hydration helps with recovery from symptoms such as fever and coughing, both of which can easily dehydrate you.

To store water (or some other healthy beverage) you need while going outside and keeping yourself hydrated during the coronavirus lockdown, you will need a strong, good-quality water flask, of which seven are listed here:
