(FOX40.COM) –– Weather temperature levels might be on the rise in the Sacramento area, however swimming in the cold waters is still considered harmful, according to the National Weather Condition Service.

" Be careful if headed to location waterways," the National Weather Service (NWS) stated. "Local waterways are running cold and quickly. Constantly use your life vest and consider cold water protection gear."

NWS alerted that even if it's warm outside, it does not indicate the water is warm.

" Cold water can kill," NWS said.

Cold water drains body heat up to four times faster than cold air, according to NWS. When a body hits cold water, "cold shock" can cause significant changes in breathing, heart rate and high blood pressure.

" The abrupt gasp and fast breathing alone develops a greater risk of drowning even for positive swimmers in calm waters," NWS stated.

To help avoid potential risks NWS advised individuals who choose to go into the water to always use a life vest due to the fact that it "considerably increases opportunities of survival."

NWS included, "When cold chock and hypothermia begin to impact your capability to act and think, lifejackets and floatation can create additional time for help to show up or for you to leave danger."
