To conserve heat in cold water, it is helpful to adopt a heat-retaining position such as the Heat Escape Lessening Posture (HELP) by crossing your arms tightly against your chest and bringing your knees up towards your chest. This position helps minimize heat loss from your body's core. Additionally, try to keep your head out of the water to prevent heat loss through your head.
Drinking cold water may temporarily increase your metabolism as your body works to warm the water to body temperature. However, this increase in metabolic rate is small and not sustained. Overall, cold water itself is not a significant factor in affecting your metabolism in the long term.
After taking a hot water bath, the blood vessels near the skin dilate to release heat, causing the body's core temperature to drop temporarily. This can make you feel cold until your body temperature stabilizes and the blood vessels constrict to conserve heat.
The position of hot and cold water affects the speed of convection in a fluid. When hot water is at the bottom and cold water is at the top, convection currents are established as the warmer fluid rises and the cooler fluid sinks, creating a more pronounced and faster circulation pattern compared to when the positions are reversed. This is due to the difference in densities of the hot and cold water, which drives the flow of fluids in a specific direction.
Isn't cold water already cold? I would say cold water gets cold first. I've heard that hot water freezes faster than cold water.
When water is cold, it changes into ice, which is the solid form of water.
Our body temperature is high then cold water so when it comes in contact with our body energy in the form of heat is transferred from body to water so it decreases our body temperature and we feel cold.

Because, when you have been swimming, you have been in the water, and water is sometimes cold, so when the cold has entered your body, your body goes cold.
The rate at which the body loses heat in cold water depends on factors like water temperature, body composition, and level of physical activity. Generally, the body loses heat much faster in cold water compared to cold air, as water conducts heat away from the body 25 times faster than air. Hypothermia can occur in cold water in as little as 15 minutes.
A cold water basin is a small body of water that acts as a drainage area for a river. It is called a cold water basin because the water is usually moving and therefore cold.
Sitting in a cold bathtub helps cool down your body because the cold water draws heat away from your skin, lowering your body temperature. This process is known as conduction, where heat is transferred from your body to the cold water.
The rate at which the body loses heat in cold water depends on factors such as water temperature, body size, body composition, and exposure time. In cold water, heat can be lost 25 times faster than in air of the same temperature due to the higher thermal conductivity of water. Hypothermia can set in quickly in cold water if the body is unable to generate enough heat to maintain its core temperature.

stand in cold water everyday and increase it a bit more everyday
Drinking cold water can slightly increase calorie expenditure as the body works to bring it to body temperature. However, the difference is minimal and not significant for weight loss. Staying hydrated with either cold or room temperature water is more important than focusing on the slight calorie difference.
When you get hot, if you drink cold water it will make you feel good.
The hot water on your skin opens your pores, and makes you sweat. The sweat evaporates, taking body heat away - making you feel cold. When your body is cold - you shiver.
