Dehydration is a big problem for me and moisturisers are a necessity. (Look at me with all the big words pouring out.) I prefer to use moisturising wipes that are antibacterial and fragrance free if I can find them, but rubbing alcohol and a wash cloth can make a good substitute if needed.
Also I have a caffeine addiction that causes a lot of grief as caffeine dehydrates and I have to rehydrate after it wears off. Refilling a pop bottle with clean water and chilling it can help relieve the thirst that follows a caffeine crash and the Charley horse that usually follows a night of work in a hot store. One twenty ounce bottle of water after work can keep me from having to walk in the house with a cane in the morning.
Water is best for rehydration of course but can be hard to drink if not chilled, so I sometimes add those little Mio flavors (or an equivalent) to it or just buy the flavored water. (I prefer the coconut flavored ones or Black Cherry.) Another good source of hydration is Powerade or Gatorade of course, and these treatments can help replace other important things in the body as well. Also, plus points for sugar fix. While they have sodium in them they are still healthier than soda pop.
Also, if you do not have a pool or spa, be sure to soak in a tub every now and then, this helps to rehydrate the outer layer. Not talking about your daily bath here, just soak up some clean H2O when you get the chance. It is also a great way to cool off in the heat.
The thirst that comes with summer heat or winter winds is always a problem and rehydration is key to a healthy life. Someone once said, "An ounce of prevention is worth a pound of cure" and it still applies today.
Until next time, keep it wet.
