MEDICAL PHYSIOLOGY

Detailed explanation-1: -When you’re suddenly immersed in cold water, your body reacts involuntarily. It can cause blood vessels in your skin to close making it harder for blood to flow around the body. Your heart then has to work harder and your blood pressure increases. In the worst cases you could even have a heart attack.

Detailed explanation-2: -Scientific studies have found that taking a cold shower increases the number of white blood cells in your body. These blood cells protect your body against diseases. Researchers believe that this process is related to an increased metabolic rate, which stimulates the immune response. Increased willpower.

Detailed explanation-3: -Every time you take a cold shower, your body undergoes a stress response. The rush of cold water activates the sympathetic nervous system, better known as the “fight or flight” response. During this response, your body releases the stress hormones norepinephrine, cortisol and adrenaline.

Detailed explanation-4: -Cold Water Immersion can trigger involuntary gasping, rapid breathing or hyperventilating due to the “shock” of sudden immersion. This uncontrolled rapid breathing can quickly create a drowning emergency if you inhale water and cannot stay afloat. Cold water can cause a sudden spike in heart rate and blood pressure.
