So, if you want to promote healthy hair, take 10 minutes to ensure your hair is dry before going outside.
The short answer is no. Colds are caused by viruses, so you can't catch a cold from going outside with wet hair. And wet hair won't make you more attractive to germs. People often associate going outside with wet hair with getting sick because exposure to germs is more likely when you go outside.
You cannot get sick from simply going outside with wet hair. “Hair being wet is not the cause for catching a cold,” Dr. Goldman says. “A microorganism, such as a virus, has to be involved to cause a cold.”
Other “shower don'ts” experts advise against:
You should wait at least two hours after a hot shower before hopping into bed, according to experts. Hot showers raise your body temperature and wreaks havoc with natural triggers that help you fall asleep.
It might surprise you to find out that neither cold weather nor wet hair can cause you to catch pneumonia. In fact, pneumonia in itself isn't contagious, so you can't really “catch” it at all.
Going to sleep with wet hair can be bad for you, but not in the way your grandmother warned you. Ideally, you should be going to bed with completely dry hair to reduce your risk of fungal infections and hair breakage. Sleeping with wet hair could also result in more tangles and a funky mane to tend to in the morning.
Sleeping with wet hair can lead to a host of problems for the scalp: unwanted bacteria, fungal infections, skin irritation, itchiness, dryness, redness, and dandruff," says hairstylist Miko Branch, co-founder of hair care brand Miss Jessie's Original.
If you like to linger in the shower for longer than 15 minutes, you might want to rethink your hygiene routine. According to board-certified dermatologist Dr. Edidiong Kaminska, MD, the recommended maximum shower time is about 5 to 10 minutes. This is enough time to cleanse and hydrate the skin without overdoing it.
Showering for too longBetween the steam, streaming water, and warmth, it's tempting to spend 15, 20, even 30 minutes in the shower, but many experts say anything more than 10 minutes is too much. “You shouldn't shower for more than 5 to 10 minutes,” says Dr. Farris.
Unsurprisingly, a person would develop quite a funk after 365 showerless days. Rokhsar said your stench likely would come as a result of the bacteria and dead skin accumulating on you. After a year, he said, you'd have a build-up of skin stratum corneum, or dead skin on top of your skin.
If your hair has prolonged exposure to the sun, UVA and UVB rays can damage the outside cover of the hair strand, called the cuticle, says dermatologist Wilma Bergfeld, MD. “Sun damage can come in the forms of discoloration, dry and brittle strands, broken or split ends, thinning and frizziness,” says Dr.
Water expands in volume during freezing temperatures, so it forces the hair shaft to expand and lifts hair cuticles. Wet hair in freezing temperatures can be exposed to environmental damage which makes it easier for hair to get split ends.
It's no secret that freezing temperatures and cold wind can take a toll on your skin, but so can showering too often. “Overshowering can lead to dryness, redness, and irritation of the skin, and even precipitate skin conditions such as eczema,” Dr. Robinson explains.
Protecting your hair from the cold weather
During the colder months of the year, try and avoid washing your hair when you don't have time to dry it. "Either do it before bed, or get up an hour earlier, there's no excuse," Collier advises.
“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.
Only shower twice a day if it is totally necessary. Excessive exposure to soap and water, especially hot water, can throw off the skin's natural balance.
Dermatologists suggest that the average shower should be between five and 15 minutes, but it depends on what you plan to do in the shower. Shorter, cooler showers are generally better for your skin. Overusing soap or showering in hot water can negatively impact your skin and hair.
Regardless of your personal preferences, the best of all times to shower is probably at night. "If you want to feel like you're a master of hygiene, then a nighttime shower is your best bet," Backe says. "You get into bed clean, effectively minimizing the spreading of germs from the day's events.
Take warm, rather than hot, showers and baths
Hot showers and baths can cause dizziness by raising blood pressure.
Specifically, sleeping on the side or back is considered more beneficial than sleeping on the stomach. In either of these sleep positions, it's easier to keep your spine supported and balanced, which relieves pressure on the spinal tissues and enables your muscles to relax and recover.
It's best to leave hair down while sleeping if possible because this reduces the number of tangles that occur during rest time. If you want to wear your hair down while you sleep, avoid rubbing it against the pillow while you're asleep.
The secret is not to pull your hair so tightly against your head that it puts pressure on the scalp while you sleep. Your hair should be secure enough that it can't snarl or tangle, but not styled in a way that encourages friction or breakage.
