Dry, indoor air can drain moisture from your skin while you sleep, especially in colder months. A humidifier adds moisture to the air which can help maintain your skin's hydration levels overnight.
Consider Electrolyte-Rich Beverages
Low levels of sodium, potassium, and magnesium can prevent your body from retaining water effectively. Drinking an electrolyte-rich beverage, like coconut water, before bed can help balance your body's fluid levels overnight.
Water is a great choice, in general. If you're dehydrated because you've been sweating a lot — from vigorous exercise, for example — a sports drink might be your best choice. If you're dehydrated from vomiting or diarrhea, choose an oral rehydration solution.
The researchers found that while water — both still and sparkling — does a pretty good job of quickly hydrating the body, beverages with a little bit of sugar, fat or protein do an even better job of keeping us hydrated for longer.
Dry skin often responds well to lifestyle measures, such as using moisturizers and avoiding long, hot showers and baths. If you have very dry skin, your doctor may recommend a moisturizing product formulated for your needs.
Use an ointment or cream rather than a lotion.
Ointments and creams are more effective and less irritating than lotions. Look for a cream or ointment that contains one or more of the following ingredients: Jojoba oil. Dimethicone.
Petroleum jelly is an occlusive ingredient, which means it creates a barrier over your skin that prevents water loss. Simply apply a very thin layer as the final step of your skincare routine, wait about 30 minutes, then go to sleep.
Sweet Almond Oil: Gentle and Nourishing
Its light texture allows it to penetrate deeply into the skin, providing long-lasting moisture. The fatty acids in sweet almond oil help the skin retain moisture, making it an excellent option for those with dry or flaky skin.
Petroleum jelly is an oil-based product that forms an oily film over the surface of the skin. This oily film seals in moisture, helping keep skin hydrated and soft. According to a 2016 review article, Vaseline prevents more than 98% of water loss from the outer layer of the skin.
You can do a few things to keep your skin moist and healthy: Put moisturizer on right after you bathe. Use a humidifier when the air is dry. Wear natural fibers, such as cotton and silk, because they allow your skin to breathe. (Wool, though natural, can sometimes irritate your skin.)
When skin loses water too quickly, it becomes dry. This can happen for many reasons. Everyday things, such as using deodorant soaps and harsh cleaning products, can strip oils and fats from our skin. Taking long, hot showers can also dry your skin.
Dry skin occurs when skin doesn't retain sufficient moisture. This can happen as a result of frequent bathing, use of harsh soaps, aging, or certain medical conditions. And for those in colder climates, it can stem from cold, dry winter air.
Milk is more hydrating than water
The same can be said for oral rehydration solutions that are used to treat diarrhea. Those contain small amounts of sugar, as well as sodium and potassium, which can also help promote water retention in the body.
Salt provides sodium, which is an electrolyte that helps hydrate the body. However, if you're already drinking adequate water and consuming sodium in your meals, you don't need the extra salt in your water. Take it from my experience: There's no need to drink salty water all day—and boy am I thankful for that.
