Summer heat: While Hiking a sufficient amount of liquid to carry Naturopathy naturopathy specialist portal

How can heat-related prevent illness?

Hiking tours in the summer can increase the risk of heat-related health complaints. Often, such disorders are not solely due to the heat, the fluid loss plays a very important role. Therefore, it is important to carry on long walks and hikes, plenty to drink with.

In the current investigation, the Arizona State University, it was found that many heat-related illness cases could be avoided if Hiking in the summer, just when the affected persons would be adequately liquid. The results of the study were published in the English-language journal “International Journal of Environmental Research and Public Health”.

Twelve were investigated taking

For the study, twelve were asked to the participants (seven women and five men at the age of 20 years), to Hiking to a day with a moderate temperature (approximately 20 degrees Celsius) on a mountain. This was repeated on a hot day (about 40 degrees). The Participants were previously asked as much liquid to take, how to you assumptions, to need. In addition, they were asked to walk as quickly as possible, to feel but without the uncomfortable.

What was studied?

Each time, the Participants walked four times up the mountain and back down again. Before you start your walk of the resting metabolism of the participants was recorded, so their energy production during the walk to estimate. In addition, your weight before, your heart rate, your core temperature and hydration state, and after the hike measured. The drinking behavior of the Participants was monitored during the entire hike.

Performance was impaired in hot weather

The researchers were trying to figure out what exactly is going on in the body if this responds to heat stress. In particular, the liquid household were analysed, the core temperature and the amount of sweat. Thus, the research group found that compared with fashion weather rates, conditions, performance is affected by migratory individuals during hot weather conditions.

Slower speed and longer exposure to Heat

This led to a slower speed during the hike, which was in turn associated with a longer time in sun and heat, thereby increasing the risk of heat-related disorders increased, explains the Team.

Participants often had too little liquid here

The research group also noted that most of the individuals took enough water to compensate for your fluid loss through sweating with you on your hike. In addition, you could observe that less fit participants in the most negative of heat stress were affected, and overall, poorer services than their fitter colleagues.

On the basis of the obtained data, the researchers were able to the Rate of fluid loss of Participants due to the reduction of body weight to calculate. On average, the subjects lost inside, and subjects, approximately one percent of body weight – regardless of whether it was hot or not.

How was the drinking behaviour of the Participants?

Under hot conditions, the sweat rate of the Participants was higher, and the affected people drank more, which led often to the fact that they took the entire brought in to be liquid. In temperate conditions, the sweat rate was low, but the migrants were also less liquid.

Possible reasons for a drop in performance

A body weight loss of a per cent is considered manageable and does not lead probably to a detrimental drop in performance. However, when people are Hiking for longer than 80 minutes under hot conditions and not enough liquid, but it can lead to greater losses in body weight, explained the research team.

What was the impact of the heat on performance?

Overall, hot conditions affected compared to moderate conditions, the wall performance by eleven percent. In addition, the aerobic capacity was reduced by seven percent, and the Rate of perceived exertion increased by 19 percent. In addition, a higher core temperature in the body was in hot temperatures, reports the researchers.

In the heat, long travel times should be factored in

On average, the Participants needed to be under hot conditions, about 20 minutes longer to hike than under temperate conditions, which could increase the likelihood of developing a heat-conditional Suffering, exponentially, so the research group. This should take account of the wandering people, in particular, when you have planned a longer hike. There is always a sufficient amount of liquid to be carried. (as)
