What should you do if you fall overboard into cold water? tread water or swim around to generate heat. remove any unnecessary clothing. try to reboard your boat, even if it is swamped. try to float on your stomach with legs extended?

“Try to reboard your boat, even if it is swamped” is the correct answer.

Further details:

If you fall overboard into cold water, then you must have to climb back on the swamped boat rather than stringing in water. By doing this, it helps you to conserve energy, and retain your body temperature. And also, the boat would be easier to find out by rescue team and this would help in more effective rescue.

Some another treatment of falling into cold water:

Try not to panic. Attempt to deal with your relaxing. Clutch something or remain as still as conceivable until your breathing settles down. Concentrate on coasting with your head above water until the virus stun reaction lessens.  At the point when your breathing is leveled out, perform the most significant capacities first before you lose smoothness (10-15 minutes after submersion).  In the event that you were not wearing a PFD when you entered the water, hope to check whether one is gliding around you and put it on right away. Try not to take off your clothes. A layer of water caught inside your dress will help protect you.  Concentrate on finding and getting everybody out of the water rapidly before you lose full utilization of your hands, arms, and legs. Attempt to reboard your boat, regardless of whether it is overwhelmed or inverted, or whatever else that is drifting. Get as much of your body out of the water as could reasonably be expected.
