Travel Is Good For Your Health

Americans are losing their vacation days, leading to more stress, anxiety and other negative effects because of not taking time off from work. In fact, a report by Project: Time Off, shows U.S. employees took about 16 vacation days in 2013, down from about 20 in 2000. Apart from taking away yourself the chance to improve your productivity and work performance, not taking a break can lead to overloaded stress and other potentially damaging. 1.

After all, vacations offer the chance to relax and restore your health. 2. You should travel to new places because traveling somewhere new can enable you to put yourself in new surroundings and recharge your brain power.

3. According to Dr. Margaret J. King, the director of the Center for Cultural Studies & Analysis, “There are lots of psychological benefits when you travel from home and work to ‘third places’, not just experiencing the environment. With a short list of activities each day, freed up from the projects and relationships, the mind can reset, as does the body, with stress relief the main outcome.” she says.

Little sleep mixed with high stress can lead to anger and negative consequences on your cognitive performance and efficiency. Max Hirshkowitz, chairman of the board of the National Sleep Foundation says a vacation is a great opportunity to catch up on sleep. 4. “Keep that time,” he says. “Make it an important thing you need.”

Many studies suggest that travel can improve our emotional state. A 2014 survey conducted by Diamond Resorts International found over three-quarters of people said feeling happier when they planned a trip at least once a year. Dr. Leigh Vinocur, a certified physician and spokesperson for the American College of Emergency Physicians, isn’t surprised by the findings. “It’s hard to sit on a beautiful beach somewhere and think about paperwork or deadlines. That is why over three-quarters of people to the Diamond Resorts International survey reported feeling happier when they regularly had a vacation. Regular vacations while taking time for yourself and your family lowers your stress level. 5.” she says. Besides, studies show that looking back on the pleasant vacation may keep happiness long after your trip.

A.They have bad effects on your health, experts say.

B.Traveling has many advantages, with stress relief topping the list.

C.Travelers may be more active than sitting in an office chair all day.

D.Travel can help us reset our emotions and actually increase compassion.

E.But simply taking some time from your demanding workday schedule isn’t enough.

F.To feel more energized, the NSF recommends at least seven hours of sleep per night for adults.

G.It also decreases the production of all the stress hormones that contribute to damaging our health.

    A number of studies show that sports and other physical activities can contribute to the development of self-esteem (a feeling of pride in oneself). For example, Canadian scientists found that sixth-grade students who were more physically active had considerably higher levels of self-esteem. A study in Switzerland found that teenagers who took part in sports clubs were healthier, including being better socially adjusted, feeling less anxious, and generally being happier about their lives. Similar findings were reported in a study of Latino students, where participation in school sport was found to be greatly associated with self-esteem.

There seems little doubt that part of the potency (潜能) of sports lies in their social setting. There are a lot of facts showing the importance of social connectedness (关联性) for healthy child and teenager development, and sports offer a popular and engaging setting for social interactions. Involvement in team sports has been positively associated with social acceptance and a sense of belonging, especially where such involvement is characterized by positive coaching, progressive skill development, and peer support.

But, the social setting of sports can exclude as well as include. There is now evidence that boys’ and girls’ experiences of sports can be very different, and this can affect the contribution they can make to the self-esteem of players. Peer acceptance seems to be an important factor in determining the relationship between sport participation and self-esteem, and girls can be particularly sensitive to negative judgments. And studies have found that many ‘girly’ boys and girls benefit most from non-competitive physical activities.

So, a note of caution ought to be sounded in case sports are considered to be a cure. Much of the literature on the most positive psychological (心理的) outcomes associated with childhood and youth sports stress the absolute importance of positive experiences. It will surprise no one that bullying, excluding or abuse experiences will harm, rather than support the development of self-esteem, and well-being in general. Sadly, it will also not be a shock to learn that many children’s introductions to sports are far from improving the quality of life.

The great developmental psychologist Jean Piaget argued that the foundations of self-esteem were laid between the ages of about 6 and 11 years of age. Importantly, this is also the time when children are most likely to be introduced to sports. We should know the importance of positive early sporting experiences for the development of both self-esteem and on-going participation in sports and other physical activities. Teachers, coaches, and parents have a responsibility to ensure that these experiences ‘catch’ as many children as possible, and for this to happen they need to remember ‘the principles of child development’: Children are not mini-adults.

Problems arise when adults forget these principles, and kid themselves into thinking that they are coaching future Olympians or Super stars. Unluckily, evidence suggests that talented children are most likely to stand out when they are given time to develop, to play, and to remain children.

Children are not miniature adults, and their enjoyment of sports (and their self-esteem) can suffer when adults forget this!
