Cold showers can help reduce inflammation, relieve pain, improve circulation, lower stress levels, and reduce muscle soreness and fatigue. Hot showers, meanwhile, can improve cardiovascular health, soothe stiff joints, and improve sleep.
Since hot showers open up your pores, it only makes sense that cold showers tighten your pores. So which is better: hot or cold? It's all about your individual needs. If you're prone to dry skin, a cold shower will help you retain natural oils in your hair and keep your skin hydrated.
Cold water can help close pores, preventing dirt and bacteria from getting into the skin. Cold water can also help to reduce inflammation and redness in the skin. Cold showers can increase circulation, which gives your skin a healthy glow.
Going from a hot to cold shower — even for a couple of minutes — might protect you from circulating viruses. The shock of cold water can stimulate the blood cells that fight off infection (leukocytes).
Cold water tightens your pores and reduces the overproduction of sebum and excretion of acne-causing bacteria. In contrast, hot water opens them and does the complete opposite, leaving your skin more prone to irritation.
Beneficial for your hair
Finishing a shower with a cold blast can help lock moisture in your hair, while also tightening your hair follicles, meaning reduced hair loss. Additionally, cold water helps to close hair cuticles, which enables the hair to reflect light resulting in a high shine.
How often should you shower? While there is no ideal frequency, experts suggest that showering several times per week is plenty for most people (unless you are grimy, sweaty, or have other reasons to shower more often). Short showers (lasting three or four minutes) with a focus on the armpits and groin may suffice.
“Humans tend to perspire at night,” Dr. Goldenberg said. “When you wake up in the morning, there's all this sweat and bacteria from the sheets that's just kind of sitting there on your skin.” So take a quick shower in the morning, he said, “to wash all of that gunk and sweat off that you've been sleeping in all night.”
Many doctors say a daily shower is fine for most people. (More than that could start to cause skin problems.) But for many people, two to three times a week is enough and may be even better to maintain good health. It depends in part on your lifestyle.
After 30 days of cold showers, most individuals report feeling more alert, having more energy, having healthier skin and hair, improved mental health and resilience, improved circulation, and more.
Benefits Of A Cold Shower Before Bed
When you sleep, your body temperature lowers. By taking a cool shower before bed, you're showing your body that bedtime is near by starting the temperature-lowering process. The cool water helps trick your whole system into sleep mode.
Cold exposure helps boost metabolism and fat burning, but the effects of a cold shower are minimal. Sure, a cold shower might help you burn a few more extra calories and keep you more alert, but it is not a long term, effective solution for weight loss.
Lukewarm water is advisable to wash your face with, but cold water has its benefits, too. Cold water tightens the appearance of your skin, so it may make you look renewed and refreshed. It also helps boost your circulation, which can help give your skin a healthier appearance, albeit temporarily.
Lowered Body Temperature
When you take a cold shower or spend a few minutes in your cold plunge, your body's temperature will dramatically decrease. As a result, your body will release chemicals—such as melatonin—which researchers believe induces sleep.
Plus, a cold shower can boost sperm count. A recent study from the University of California at San Francisco found that men who were exposed to 30 minutes of “wet heat” (so showers and baths) per week that they stopped this practice saw their sperm count increase by 491%.
In general, showering every other day or every few days is enough for most people. Keep in mind that showering twice a day or frequently taking hot or long showers can strip your skin of important oils. This can lead to dry, itchy skin.
It's also possible to overdo the cold. "If the water temperature is too cold, below 10°C, and you take a long shower, you can get hypothermia. I recommend cold showers between 10°C/50°F and 16°C/60°F," Green says.
Keep it short: When first trying cold showers, aim to spend no more than 30 seconds under the cold water. You can increase the time as your body adapts. Ease in: Instead of jumping into a cold shower, start with the water warm, then gradually adjust the temperature downwards.
Showering every day, she said, is unnecessary. Every two, three or even four days is acceptable as long as you don't stink up the place. She said, generally, the organisms naturally found on her skin protect us from picking up harmful germs.
