Will Day Spas Help Me Combat Aging?

Tuesday, March 8th, 2011

Only children like the thought of getting older, most adults want to halt the aging process or even start it going backwards, if they could. However, as we all know, that is impossible, which is why they invented the next best thing, day spas, beauty salons and all the creams, lotions and treatments that they provide to endeavour to stem the results of aging.

And to be fair, some of them can do a pretty decent job. In this article, we will look at the services provided by day spas. A day spa is similar to a beauty salon but with water events offered too. A day spa is an extended beauty salon and may be situated in a larger place, especially if there is a swimming pool included.

The main difference between a beauty salon and a day spa is that in a beauty salon, you are given all your treatments and then you leave, whereas in a day spa, you can hang about a bit in between treatments or remain in the pool or sauna longer than the allotted 15-20 minutes, if you want to.

A day spa is more peaceful and individuals tend to spend more time in them. There might even be a bar or a juice bar or / and a cafe to buy light, health snacks like a salad or a vegetarian sandwich.

One of the most popular treatments at a spa is the massage. There are different sorts of massage, so it might take you a while to find your favourite if you have not undergone a massage before. Some of the types of massage often on offer are: Thai massage, Japanese massage, full body massage, oil massage and a foot massage. Additionally, some spas will put hot towels on your face to clean out pores and hot stones on your spine for deep heat.

You may also fancy a body wrap or a mud pack or even a mud bath! These treatments can actually make your skin look younger by deep cleaning the pores of pollutants, make up and everyday grime. They make you feel ten years younger for a while, and they tighten up the skin and make you look younger for a while as well.

Maybe you would rather concentrate on your hands and / or feet? Then you could have a full manicure and / or pedicure. These treatments could include a local massage, skin and nail treatments followed by an oil treatment. You could also have a foot spa, which is like a mini-jacuzzi. A foot spa is wonderful if you have been on you feet all day. They may also use heated socks or mittens.

Half an hour in a hot tub, a jacuzzi or even a steam box are other services that may be available at day spas which you are unlikely to find in a beauty salon. When you arrive at the day spa, check out any cheap day packages. You can frequently save a bit of money on the individual treatments supplied.

Saturday, March 5th, 2011

Have you ever thought about getting away from it all and going on a colossal detox mission? There is a great deal to be said for giving your body a break from all the pollution, smoke, noise, fast-paced lifestyle and stress and the substances that we use to deal with that stress like alcohol, tobacco, coffee and worse. It is not so bad while your body is young, but as it gets older, it becomes less capable of countering all the stuff we give it to handle.

Costa Rica may sound like a long way to go to visit a spa or health resort, but it is just a flight away. The reason for selecting Costa Rica is because it is like a home from home for Americans, and the ambiance is a lot slower and more easy-going. There are lots of health spas and retreats to choose from in Costa Rica and a brief search on the Internet will reveal many of them.

Spanish is the foremost local language, but English is spoken by over ten percent of the adult population and tourist facilities are well developed in the form of exchanging currencies, restaurants and hotels. The country is unpolluted and environmentally friendly.

For example, according to Wikipedia, Costa Rica is ranked third in the world and first among the Americas in terms of the 2010 Environmental Performance Index and in 2007, the government announced that it intended for Costa Rica to be the first carbon neutral country by 2021. Moreover, the Happy Planet Index rates Costa Rica as number one in the world and also as the “greenest country in the world”.

Where better could you go to escape pollution and stress than a health spa or retreat in such a country? Many of the resorts offer stress reducing schemes that include methods of relaxation such as yoga, meditation, reiki, massage and tai-chi, although there are lots of places offering water sports such as diving, sailing and surfing. There is fantastic diving to be had in warm, clear water, which is teaming with flora and fauna.

Prices are low when likened with the United States. You can find a hotel or a room in a retreat for $25-$50 and up and a good meal will be about $2-$4. There are all types of food but particularly the sorts of food associated with Spanish and American cuisine. Vegetarians are well catered for too and there is fish and other seafood in profusion for those who rather it to meat.

Some of the health spa resorts have rooms for you to stay in while others offer just day time courses. The retreat style resorts are live-in and many are similar to communes. The facilities vary from being ‘hippyish’ and pretty basic in some of the retreats to being as modern as anywhere in the world in the health spas, offering swimming pools, gymnasiums and hot tub spas.

All in all, if you are thinking about going abroad for a healthy, restful break, a vacation in Costa Rica ought to be on your short list.

On the western and eastern coasts of North America in both the Pacific and Atlantic Oceans, is to be found the sea nettle jelly fish or Chrysaora. It generally has its body covered in white dots and reddish-brown stripes and seems saucer-shaped. Its four oral arms are present on the underside of the body and all along the outer edge it has tentacles a few feet long.

These tentacles have nematocysts all along it which are rather like capsules and are barbed throughout. It contains toxins that can paralyze the victim. When the sea nettle touches anything hard, the pressure on the tentacles activates the nematocysts and the powerful venom gets injected into the foreign body. This is how the sea nettle jellyfish gets its prey for food.

Even when the sea nettle jelly fish comes in contact with a very big predator, it uses the same method to paralyze it, whereas the smaller prey can easily get killed by the poison. Even on humans, the effect of the sea nettle jelly fish sting is quite severe at times. It usually creates a rash which can burn and prove quite painful. The allergy could also get serious at time.
