As the summer days get hotter, it becomes even more important to drink plenty of fluids. Staying hydrated is essential for health and wellness. Our bodies are more than 60% water, and every single cell requires water.

A lack of water can lead to dehydration, which is a condition that occurs when you don't have enough water in your body to carry out normal functions. Even mild dehydration can drain your energy and make you tired. Becoming extremely dehydrated or overheated can lead to heat stroke and even death.

Proper hydration is central to some of the most basic physiological functions in our bodies: regulating blood pressure, body temperature and digestion. Let’s take a closer look at the many ways water works wonders in our bodies:

• Brain. When hydrated well, our brain cells are better supplied with fresh, oxygen-laden blood and the brain remains alert.
  
  
• Heart. Water is required to regulate heart rate and blood pressure and supply oxygen to the brain and tissues.
  
  
• Kidneys. Water controls electrolyte levels and helps remove waste from the body.
  
  
• Cells. Water transports nutrients, produces energy and disposes of waste.
  
  
• Muscles and joints. Water acts as a lubricant to cushion joints and keeps muscles working properly.
  
  
• Skin. Water helps the skin protect the body from germs and can help prevent infections and allergic reactions.

Each day, we naturally lose water ‒ by breathing, perspiring and eliminating waste. It is important that we replenish our water supply by consuming beverages and foods that contain water. The general recommendation of adequate fluid intake per day is about 15.5 cups for men and 11.5 cups for women. This includes fluids from both beverages and foods.

Most healthy people can stay hydrated by drinking whenever they feel thirsty. However, some people may need to modify their fluid intake based on the amount of exercise they engage in, their environment and their overall health. Athletes, in particular, need to pay close attention to their hydration needs, especially during the summer.

Whether you are an athlete or not, be sure to stay hydrated on these hot, humid days. Make drinking plenty of water a regular part of your daily routine!
