The highest rates of drowning globally are among children under five, and young children should be supervised, regardless of whether they can already swim. The danger increases when they are alone. A baby can drown in the bathtub, in the toilet, and even in a small bucket filled with less than an inch of water. It only takes around 2 minutes underwater for an adult to lose consciousness, and only between 30 seconds and 2 minutes for a small child to die. Choosing supervised swimming places is safer. Many pools and bathing areas either have lifeguards or a pool safety camera system for local or remote monitoring, and some have computer-aided drowning detection. Bystanders are also important in detection of drownings and in notifying them (personally or by phone, alarm, etc.) to lifeguards, who may be unaware if distracted or busy. Evidence shows that alarms in pools are poor for any utility. The World Health Organization recommends analyzing when the most crowded hours in the swimming zones are, and to increase the number of lifeguards at those moments. Learning to swim:  Being able to swim is one of the best defenses against drowning. It is recommended that children learn to swim in a safe and supervised environment when they are between 1 and 4 years old. Learning to swim is also possible in adults by using the same methods as children.
Significant amounts of water usually only enter the lungs later in the process.While the word "drowning" is commonly associated with fatal results, drowning may be classified into three different types: drowning that results in death, drowning that results in long-lasting health problems, and drowning that results in no health complications. Sometimes the term "near-drowning" is used in the latter cases. Among children who survive, health problems occur in about 7.5% of cases.Steps to prevent drowning include teaching children and adults to swim and to recognise unsafe water conditions; never swimming alone; use of personal flotation devices on boats and when swimming in unfavourable conditions; limiting or removing access to water, such as with fencing of swimming pools; and exercising appropriate supervision. Treatment of victims who are not breathing should begin with opening the airway and providing five breaths of mouth-to-mouth resuscitation. Cardiopulmonary resuscitation (CPR) is recommended for a person whose heart has stopped beating and has been underwater for less than an hour. Causes
A major contributor to drowning is the inability to swim. Other contributing factors include the state of the water itself, distance from a solid footing, physical impairment, or prior loss of consciousness. Anxiety brought on by fear of drowning or water itself can lead to exhaustion, thus increasing the chances of drowning. Approximately 90% of drownings take place in freshwater (rivers, lakes, and a relatively small number of swimming pools); the remaining 10% take place in seawater. Drownings in other fluids are rare, and often related to industrial accidents.
