3161-919: A week after creating a Douyin account. TikTok food trends are specific food recipes and food-related fads on the social media platform TikTok. This content amassed popularity in 2020 during the COVID-19 pandemic , given that many were inclined to eat at home while simultaneously turning to social media as a form of entertainment. While some TikTok users share their diets and recipes, others expand their brand or image on TikTok through step-by-step videos of easy and popular recipes. Users often refer to food-related content as "FoodTok." "Midsize" fashion gained greater exposure on TikTok after many creators opened up about not able to find clothing sizes that fit them well. Women's apparel can roughly be divided into petite, straight, and plus sizes, leaving gaps in between. Realistic videos about how differently pieces of garment fit on

The exact mechanism for this effect has been debated and may be a result of brain cooling similar to the protective effects seen in people who are treated with deep hypothermia . The actual cause of death in cold or very cold water is usually lethal bodily reactions to increased heat loss and to freezing water, rather than any loss of core body temperature. Of those who die after plunging into freezing seas, around 20% die within 2 minutes from cold shock (uncontrolled rapid breathing and gasping causing water inhalation,

The fastest way to assist is to throw a buoyant object (such as a lifebuoy or a broad branch). It is very important to avoid aiming directly at the victim, since even the lightest lifebuoys weight over 2 kilograms, and can stun, injure or even render a person unconscious if they impact on

Submerging the face in water cooler than about 21 °C (70 °F) triggers the diving reflex , common to air-breathing vertebrates, especially marine mammals such as whales and seals . This reflex protects the body by putting it into energy-saving mode to maximise the time it can stay underwater. The strength of this reflex is greater in colder water and has three principal effects: The reflex action

A water temperature of 10 °C (50 °F) can lead to death in as little as one hour, and water temperatures hovering at freezing can lead to death in as little as 15 minutes. This is because cold water can have other lethal effects on the body. Hence, hypothermia is not usually

This has been called " dry drowning ", as no water enters the lungs. In forensic pathology , water in the lungs indicates that the person was still alive at the point of submersion. An absence of water in the lungs may be either a dry drowning or indicates
4905-420: The lungs . Even small quantities can cause the extrusion of liquid into the lungs ( pulmonary edema ) over the following hours; this reduces the ability to exchange the air and can lead to a person "drowning in their own body fluid". Vomit and certain poisonous vapors or gases (as in chemical warfare ) can have a similar effect. The reaction can take place up to 72 hours after the initial incident and may lead to
5014-412: The vocal cords constrict, sealing the airway . This prevents water from entering the lungs . Because of this laryngospasm, in the initial phase of drowning, water enters the stomach, and very little water enters the lungs. Though laryngospasm prevents water from entering the lungs, it also interferes with breathing. In most people, the laryngospasm relaxes sometime after unconsciousness due to hypoxia in

Cardiopulmonary resuscitation (CPR) is recommended for a person whose heart has stopped beating and has been underwater for less than an hour. 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

Following this, a blackout may occur before the diver feels an urgent need to breathe. This can occur at any depth and is common in distance breath-hold divers in swimming pools . Both deep and distance free divers often use hyperventilation to flush out carbon dioxide from the lungs to suppress

The person can voluntarily hold their breath for some time, but the breathing reflex will increase until the person tries to breathe, even when submerged. The breathing reflex in the human body is weakly related to the amount of oxygen in the blood but strongly related to the amount of carbon dioxide (see Hypercapnia ). During an apnea,
6976-583: The bloodstream. Hypercapnia and hypoxia both contribute to laryngeal relaxation, after which the airway is open through the trachea. There is also bronchospasm and mucous production in the bronchi associated with laryngospasm, and these may prevent water entry at terminal relaxation. The hypoxemia and acidosis caused by asphyxia in drowning affect various organs. There can be central nervous system damage, cardiac arrhythmia, pulmonary injury, reperfusion injury, and multiple-organ secondary injury with prolonged tissue hypoxia. A lack of oxygen or chemical changes in
7085-423: The breathing reflex for longer. It is important not to mistake this for an attempt to increase the body's oxygen store. The body at rest is fully oxygenated by normal breathing and cannot take on any more. Breath-holding in water should always be supervised by a second person, as by hyperventilating, one increases the risk of shallow water blackout because insufficient carbon dioxide levels in the blood fail to trigger
7194-399: The breathing reflex. A continued lack of oxygen in the brain, hypoxia , will quickly render a person unconscious, usually around a blood partial pressure of oxygen of 25–30 mmHg. An unconscious person rescued with an airway still sealed from laryngospasm stands a good chance of a full recovery. Artificial respiration is also much more effective without water in the lungs. At this point,

Of people who have survived drowning, almost one-third will experience complications such as acute lung injury (ALI) or acute respiratory distress syndrome (ARDS). ALI/ARDS can be triggered by pneumonia, sepsis, and water aspiration . These conditions are life-threatening disorders that can result in death if not treated promptly. During drowning, aspirated water enters
7412-785: The chance of survival should unconsciousness occur. Hypothermia (and cardiac arrest) presents a risk for survivors of immersion. This risk increases if the survivor—feeling well again—tries to get up and move, not realizing their core body temperature is still very low and will take a long time to recover. Most people who experience cold-water drowning do not develop hypothermia quickly enough to decrease cerebral metabolism before ischemia and irreversible hypoxia occur. The neuroprotective effects appear to require water temperatures below about 5 °C (41 °F). The World Health Organization in 2005 defined drowning as "the process of experiencing respiratory impairment from submersion/immersion in liquid." This definition does not imply death or even

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 . In New Zealand's early colonial history, so many settlers died while trying to cross the rivers that drowning was called "the New Zealand death". People have drowned in as little as 30 mm (1.2 in) of water while lying face down. Death can occur due to complications following an initial drowning. Inhaled fluid can act as an irritant inside

While breath-holding triggers a slower heart rate , cold shock activates tachycardia , an increase in heart rate. It is thought that this conflict of these nervous system responses may account for the arrhythmias of cold water submersion. Heat transfers very well into water, and body heat
7957-542: The early stages of drowning, a person holds their breath to prevent water from entering their lungs. When this is no longer possible, a small amount of water entering the trachea causes a muscular spasm that seals the airway and prevents further passage of water. If the process is not interrupted, loss of consciousness due to hypoxia is followed by cardiac arrest. A conscious person will hold their breath (see Apnea ) and will try to access air, often resulting in panic , including rapid body movement. This uses up more oxygen in

8393-476: The following: The concept of water safety involves the procedures and policies that are directed to prevent people from drowning or from becoming injured in water.

An average person can last between one and three minutes before falling unconscious and around ten minutes before dying. In an unusual case with
8502-452: The head. Another way to assist is to reach the victim with an object to grasp, and then pull both of them out of the water. Some examples include: ropes, oars, broad branches, poles, one's own arm, a hand, etc. This carries the risk of the rescuer being pulled into the water by the victim, so the rescuer must take a firm stand, lying down, as well as securing to some stable point. Any rescue with vehicles would have to avoid trampling or damaging
8611-450: The lung tissues, causes a reduction in pulmonary surfactant , obstructs ventilation, and triggers a release of inflammatory mediators which results in hypoxia . Specifically, upon reaching the alveoli, hypotonic liquid found in freshwater dilutes pulmonary surfactant, destroying the substance. Comparatively, aspiration of hypertonic seawater draws liquid from the plasma into the alveoli and similarly causes damage to surfactant by disrupting
8720-857: 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
8829-399: The lungs may cause the heart to stop beating. This cardiac arrest stops the flow of blood and thus stops the transport of oxygen to the brain. Cardiac arrest used to be the traditional point of death, but at this point, there is still a chance of recovery.

9701-544: The oxygen in the body is used by the cells and excreted as carbon dioxide. Thus, the level of oxygen in the blood decreases, and the level of carbon dioxide increases. Increasing carbon dioxide levels lead to a stronger and stronger breathing reflex, up to the breath-hold breakpoint , at which the person can no longer voluntarily hold their breath. This typically occurs at an arterial partial pressure of carbon dioxide of 55 mm Hg but may differ significantly between people. When submerged into cold water, breath-holding time
