Benefits of a Cold Shower Before Bed

You might have heard about the benefits of taking a bath before you sleep; the advantages of a cold bath in particular however come as a surprise to many. The practice of taking cold baths has existed ever since Roman times, where it was particularly used for medicinal purposes. It, therefore, goes without saying that taking a cold bedtime shower brings along a series of benefits to one’s mental and physical health alike.

Whether it is simply a rejuvenating sleep, or a series of physical health improvements that you are seeking, a cold bath before heading to bed at night will prove worthwhile. Let’s find out how!

Better Quality of Sleep

The slight drop in your core body temperature, as dictated by its circadian rhythm, is responsible for inducing sleep at night. A cold shower before hitting the bed simply speeds up this temperature dropping process and enables you to fall asleep faster and sleep better and more comfortably during the night.

Taking a cold shower will initially make you alert and increase your focus. So here comes the question; if a cold shower makes you less drowsy, how is it ever going to aid your slumber let alone improve the quality of your sleep?

The answer is fairly simple. When your core body temperature rises slightly after a cold shower, your blood vessels constrict to conserve warmth for your organs and so allows you to reach a comfortable sleeping position within a little while. A shower with cold water just a few hours before sleeping, therefore, tends to relax your body and delivers a highly soothing effect, which in turn makes the quality of your sleep better.

Moreover, a rejuvenating, cold bath relieves your body of the toxins, allergens, and bacteria you have been collecting all day. You, therefore, don’t experience itchy skin or allergic reactions, thereby ensuring a peaceful and undisturbed sleep throughout the night.

Improved Immune System

The most apparently-bizarre thing you would ever listen to is that a cold shower before bed prevents you from catching a cold. It is however factually proven to be true!

As discussed earlier, taking a cold bath puts your body in a frenzy. Your organs are vital to ensure your body’s proper functioning and therefore are to be protected at all costs. To keep them warm and unfazed by the cold bath, your blood vessels deliver adequate warmth to the internal organs. Simultaneously, your body’s metabolic rate increases in an attempt to generate more heat.

As your body starts warming up, your immune system is triggered to produce more white blood cells. These white blood cells are responsible for fighting off viruses and bacteria in your body, thus preventing you from catching infections. Taking a cold bath therefore improves your immune system and makes your immune response stronger against external adversities.

Faster Metabolism

For all the fitness freaks out there, losing weight is as simple as taking a cold bath everyday!

It works in the same manner as a faster immune response does. To keep the internal organs warm after you have showered with cold water, your body increases its metabolism. This it does by increasing the production of brown fat cells. These cells actively burn more energy than most other cells and therefore significantly increase the body’s metabolism.

The higher the metabolic rate, the more warmth your body is going to produce, which is ultimately used to raise your body temperature and help you combat the icy shock. A faster metabolism helps burn more calories, thus taking a cold shower before you fall asleep an ideal choice for those struggling to stay in shape.

Skin Tightening

Where a warm shower would open up your skin’s pores and flush out the toxins and allergens accumulating on your face, a cold shower on the contrary does exactly the opposite.

As soon as you plunge into icy-cold water, the immediate effect within your body is vasco-constriction. Your blood vessels constrict to bear the icy cold shock and your skin’s pores close for a brief while. These constricted pores in turn tighten your skin and also prevent the natural oils on your skin from being flushed out. Skin tightening tends to reduce puffiness and swelling, thus giving your skin a rather refreshed and composed look.

A little while after the cold shower, your lymphatic vessels contract to allow more fluid to pass through them. This enhanced blood flow in turn lends your skin a natural glow and radiance and leaves your skin rather soft to touch.

Hair Loss Reduction

Since cold water does not cause stress to your tresses, it manages to control the frizz on your hair and prevents it from weakening.

When your blood vessels constrict from the shock brought about by icy cold water, the pores on your scalp close. These closed pores lock the natural oils and moisture within your hair and prevent them from flushing out while you shower. This keeps your hair more manageable and extra soft.

Moreover, cold water also closes the hair cuticles. These closed cuticles are smoother to touch, and additionally, reflect light to give a healthy shine to your hair. Since most of the pores on your scalp are closed, your hair, therefore, remains cleaner for long by being less exposed to grease and dirt.

Additionally, the constriction of your lymphatic vessels to allow more blood to pass through them towards the body core improves your overall blood circulation. This enhanced blood flow, therefore, allows vital nutrients to reach the hair, roots, and scalp, thereby aiding in hair growth. So, if you too want long and shiny hair from those shampoo commercials, don’t forget to take a cold shower before you sleep!

It has been proven through clinical trials that showering with cold water up to five minutes, twice or thrice weekly can help your body in becoming more resistant to stress and depression.

Icy-cold water shocks your body and causes you to become more alert. It acts as an electroshock therapy that tends to send electrical impulses to your brain, prompting it to increase your energy levels.

These electrical impulses from the peripheral nerve endings tend to release endorphins, which are popularly known as the happy hormones of your body. These hormones are associated with generating feelings of overall well-being to have a rather anti-depressive and optimistic effect.

Moreover, a rejuvenating cold water bath has also been associated with causing a decrease in the amount of stress-generating hormone, cortisol, in most individuals. Say goodbye to depression and anxiety without taking medications, by following this simple routine.
