Nothing is more beneficial for the body than having plenty of water throughout the day. From glowing skin to a healthy digestive system and better absorption of nutrients, water does a world of good. And that’s why filling up one’s water bottle first thing in the morning is a great idea to stay hydrated throughout the day. There’s a variety of water bottles available today; here are some tips to pick the right one: 1. Check if it maintains the temperature of the water While some people are absolutely fine with having water at room temperature, others require ice-cold, warm, or hot water. If one likes water to remain at a specific temperature, one should look for vacuum-insulated bottles. Here, the water in the bottle is protected from the air temperature outside, which retains its temperature. Stainless steel vacuum-insulated water bottles are the most common on the market. Copper-lined bottles and bottles with double-walled construction also provide sufficient insulation. 2. Consider the bottle’s size and volume The ideal size of one’s water bottle depends on how much daily water one needs and the duration one must wait before refilling it. For example, those commuting to and from work daily may be unable to refill their water bottles during this time.
