Water

Water is our most vital element. The body needs lots of water to carry out many essential functions, such as balancing the internal temperature and keeping our cells alive.

As a general rule of thumb, a person can survive without water for about 3 days. However, some factors, such as how much water an individual body needs, and how it uses water, can affect this.
It is recommended that each household have 1 gallon of water per day per person for at least three days in case of emergency. We are asking that you store at least an additional 3-5 gallons of water for the NESA community. If your storage area is prone to high temperatures, consider storing your water in glass bottles due to chemicals from plastic bottles leaching into water.

Effects of having no water
Humans can only survive a short amount of time without water because the body needs it for almost every process, including:

regulating body temperature through sweating and breathing
aiding in digestion by forming saliva and breaking down food
moistening mucous membranes
helping to balance the pH of the body
lubricating joints and the spinal cord
helping the brain make and use certain hormones
helping transport toxins out of the cells
eliminating waste through the urine and breath
delivering oxygen throughout the body
