Most of us wash every day, and we have our preferred methods, but how and when you do should really depend on whether you’re revving up or winding down.
For a morning wake-up call, a cold shower is usually best—a splash of chilly water over the body makes levels of cortisol and adrenaline surge briefly, giving as much punch as a caffeine hit. If stepping into an icy-cold shower first thing is just unbearable, try ending a warm shower with a 30-second blast of cold water. This will deliver an invigorating boost and—according to one large study—it will even make it less likely that you’ll take time off sick from work.
If a good night’s sleep is your goal, then a warm shower or bath about 90 minutes before bed is highly effective in helping the body and brain wind down—this lowers blood pressure; stimulates the release of the positive, happiness hormone serotonin; lowers anxiety levels; and can make cortisol levels plunge by a third. A cold shower has the opposite effect so is best avoided late in the evenings.
Of course, you might think that you can cash in on all the benefits with a morning shower and an evening bath. Rinse that thought—
dermatologists say that twice-a-day bathing is probably too much. Your skin and hair are coated in a barely visible sheen of an oily substance called sebum. This is your body’s natural waterproof gloss, and it’s constantly replenished via microscopic pores in your skin. Washing twice a day scrubs away the skin’s sebum, and without it your skin will dry out and become sore, chapped, or infected. Bath lovers, beware—long, hot soaks in a tub of bubbles feels luxurious, but it’s best to shower or bathe for only about 5–10 minutes in lukewarm water every two or three days to give time for sebum to replenish itself.In our overly washed and manicured world, skin and hair can become so depleted of their natural oils that we think we need moisturizing creams and lotions to restore their luster. Much of what you might slather over yourself is, however, nothing more than nice-smelling grease. Moisturizers don’t actually “moisturize”—they simply replace the oily protective coat that you wash down the plughole with your soap or shampoo. Added “skin nourishing” ingredients emblazoned on the packaging are mostly marketing froth that have little added effect. Similarly, hair conditioners are merely a replacement for the natural oils that the body freely makes. If you shower or bathe every two or three days, you likely won’t need skin moisturizers or hair conditioners.
