5 Surprising Cold Shower Benefits You Need To Know!

Written by Payal Karnik , MSc (Biotechnology), Diploma In Nutrition

For most of us, a cold shower seems to be the last-ditch effort at hygiene when we don’t have access to warm water or the heater breaks down. Cold showers are not popular. Few would want to begin the day shivering, especially during colder months. But what if we tell you that cold showers may benefit you in numerous ways?

Cold showers work like a wake-up boost in the morning, may relieve pain, and improve overall health. Wondering how? Scroll down to discover more benefits of taking a cold shower.

What Is Cold Hydrotherapy?

Cold hydrotherapy is the practice of using cold water for pain relief and to treat various health issues. It is a part of alternative medicine, widely used in Indian, Egyptian, and Chinese cultures(1).

In temperature-based hydrotherapy, cold or hot water stimulates blood flow to the skin and underlying tissues by constricting or dilating the blood vessels. Hydrotherapy has several benefits, including detoxification (helps to expel waste), relaxation, enhanced metabolic rate, and digestion, and hydration.

Additionally, it stimulates blood supply to the immune system and internal organs for better functioning. Overall, hydrotherapy can become a significant tool for stress relief and improving body function (1).

Taking cold showers is not a new concept and may have several health benefits.

Benefits Of Cold Showers

1. May Prevent Moisture Loss

Changes in water temperature affect the skin’s sebum production (2). Hot or warm water can strip the natural oils, leaving your skin dry. On the other hand, a cold shower prevents transepidermal water loss to maintain skin hydration levels. It also prevents scalp dryness and may help maintain healthy hair. Moreover, reduced skin hydration increases the risk of developing wrinkles and fine lines (3), (4).

2. May Improve Your Mood

Cold hydrotherapy may have an anti-depressive effect. Clinical trials show that a cold shower may send electrical impulses to the brain through the cold receptors in the skin and activate the sympathetic nervous system. This may relieve depressive symptoms. However, more rigorous research is required to validate this hypothesis (5).

3. May Boost Post-Exercise Recovery

Intense exercise often causes microtrauma and muscle tears. Experts believe that an ice bath or a cold shower constricts blood vessels and flushes waste products from the affected tissues. It reduces swelling, soreness, muscle pain, and further tissue breakdown (6 ). However, further large-scale studies are required to prove the efficacy of this routine.

3. May Warm Up Your Body

Yes! A cold shower during the winters can help you stay warm! It is because cold exposure activates the brown adipose tissue (BAT) present in your body. This tissue helps maintain body temperature in cold conditions to keep you warm. The moment you take a cold shower, your body shivers and sends nerve impulses to the brain. As a result, the muscles contract, and the BAT is activated (7).

4. May Prevent Common Health Issues

A survey involving 3018 healthy adults found that persons who took regular (hot-to-) cold showers reported a 29% reduction in self-reported sickness during a 30-day follow-up. The participants also reported an increase in perceived energy levels (like the effect of caffeine) (8).

5. May Increase Alertness

Taking a cold shower may increase alertness in humans. Cold water can increase heart rate, blood pressure, and respiratory rate (9). All these physiological changes may awaken your senses and make you alert and energetic.

The pathway of how cold shower works is unclear yet. So, more empirical evidence is required to prove all the benefits we discussed. Moreover, the studies mostly took place in a controlled setting. However, experts believe that a cold shower at home can have similar effects. Here is how you can take a cold bath and reap all its benefits.

How To Take A Cold Shower

  • Use Warm And Cold Water Alternately: Shower with cold water (or room temperature water) for a minute, and then shower with warm water. Keep alternating the temperature. This is beneficial for those who are not used to cold baths.
  • Hot-To-Cold Shower: Shower with warm water as you regularly do. However, end your shower with a cold bath for 60-90 seconds.
  • Cold Immersion: Immerse your body in a pool of cold water (≤15˚C). This is beneficial immediately after exercising. However, do not take a cold dip if you are not used to it. Consult a sports therapist before trying cold immersion.

NASM Certified Personal Trainer Rachel Rivera recommends, “Take time to work your way up to 10 minutes of a cold shower. Hum or sing to control your nervous system and stimulate the vagus nerve.”

As an extra measure, she adds, “After showering, if possible, stay naked for a bit to avoid the clothes warming you up. This will force your body to use brown fat, aka adipose tissue, to warm you up, which will aid in weight loss!”

Rivera further emphasizes the importance of taking a cold shower during the day. She says, “You can take a cold shower every day, there’s no harm in that! I do recommend taking the earlier in the day rather than later, as it may keep you awake longer if you take it before bed.”

It is also important to watch the duration of your showers. Clara Lawson, RDN, suggests, “Do not prolong your showers to preserve the natural moisture of your body. Ideally, you can take 15-20 minutes of a cold shower.”

Not everyone may feel comfortable with taking a cold dip. Sometimes, abrupt temperature changes may cause more harm than good. Let’s understand in detail.

Side Effects Of Cold Showers

Houston-based dermatologist Dr. Kemunto Mokaya jokes, “They are unpleasant to some people and can take away the ‘relaxation and joy of showering’.”
Dr. Mokaya cautions, “On a more serious note, people with heart disease should be careful. When the body is abruptly exposed to cold water, blood vessels restrict, and the heart rate and blood pressure can go up, straining the heart.”

She advises, “Avoid cold showers in young children and infants, as this can cause hypothermia (a dangerous drop in body temperature) if they are left in the shower too long.”

Dr. Lawson also voices her concern. She says, “Cold showers can get problematic for those with respiratory problems. People who easily become sick due to cold and develop breathing problems should avoid cold showers. And if you are already sick, a cold shower can worsen your condition.

She states, “In short, cold showers can’t work for everyone. If someone has a weak immunity or if your body is unable to cope up with cold showers, it’s best to avoid it.”

The Final Words

Coldwater therapy has been used for centuries to promote relaxation and a sense of well-being. While the pathway of therapeutic effects of cold showers is not clear, they have positive effects on both physical and mental health. However, a cold shower may not be suitable for everyone and may cause serious side effects. If you have heart conditions and breathing issues, avoid cold showers. And if you want to give it a try, start small and gradually introduce cold showers into your routine to avoid any serious side effects.

Expert’s Answers For Readers’ Questions

Should you take cold showers at night?

No. Cold exposure causes the body to release cortisol, and too much cortisol at night may lead to poor sleep.

Do cold showers build muscle?

No. Cold showers can help relax muscles after an intense workout.

Are cold showers good for acne?

There is no scientific proof for the claim. However, cold showers can help regulate excess sebum production, one of the many causes of acne.
