The heat is made worse by the humidity. We can normally cool ourselves by sweat evaporating from our skin, but this mechanism is compromised by increasing levels of humidity in the atmosphere, itself a result of rising temperatures. Humidity is measured by the wet bulb temperature: the lower it is, the easier it is for us to cool down. And it has been increasing, in the last 50 years.
Research suggests that above a wet bulb temperature of 31.5°C, the body can no longer cool down and, without assistance (such as air conditioning), death occurs.
“There is a reason why heat is considered a silent killer. People often don't realize they're in trouble until things are progressing rapidly,” said Kristie Ebi, an epidemiologist at the University of Washington who specializes in climate effects.
“I would expect to see an increase in deaths this year. Everywhere we are going to face extreme heat and we simply do not have the level of preparation we need.”
The worrying effects of devastating heat waves that have spread across the United States have been reported. More than 170 million Americans have been placed under a heat alert in the past year.
People living in cities dominated by concrete, particularly those in poorer neighborhoods that lack tree cover and other green spaces, are also at risk, and a report this week found that the "urban heat island" effect ” can add about eight degrees to felt temperatures. in cities such as New York, Chicago, Houston and Los Angeles. In some places, even playgrounds with hot slides are dangerous.
It is estimated that at least 10,000 people will die each year in the United States from extreme heat by 2022.
Taking a probiotic can help boost your immune system, protect you against infections, and improve your digestion and absorption of food and nutrients, including water. Probiotics also help with several conditions associated with dehydration, including diarrhea.
Drinks like coffee, sugary soft drinks, beer, wine and hard liquor, energy drinks, are all to blame for dehydration. They are loaded with sugar and other ingredients that remove water from the tissues. Good hydration has a positive effect on stress. Well-hydrated people generally report being happier, less focused and more alert. On the other hand, dehydrated people generally report being less happy, less calm, more confused and less happy.
Consequently, we can say that good hydration positively influences stress and well-being. On the other hand, dehydration has a negative influence on stress and induces bad stress. Thus, good hydration influences stress. Dr. Stookey explains how good hydration contributes to calorie burning.
