A little sweat never hurts anyone, but overheating? This is a completely different beast.
Whether you are raising in a gym that feels like an oven or is passing a heat wave, we have all had those moments where we feel like we are ready to combine spontaneously.
Subtle news: Scientists just discovered a visual deceit that deceives your body to calm down – and it’s the last thing you will expect.
Sweating it
For the study, researchers recruited five women of college to ride stationary bicycles at 72 ° F as they entered the headphones of virtual reality, exploring scenes in the “Nature VR” app.
Those who watched the “red soil” were transported to the Australian outback, immersed in the fiery, oranges and yellow reds that evoked the heat of the desert.
Meanwhile, others entered the cold world of “white winter”, where snow -covered valleys and ice dust trees set the scene for a much cooler vibe.
When the researchers compared participants’ reactions to the two VR environments, they found that their body’s essential temperatures increased much less when they were plunged into the hot scene than in the cold.
“Our findings suggest that simply looking at a hot environment can act as a powerful stimulus for thermoregulating processes, and can play a greater role than we had previously thought,” said Natasha Ragland, a graduate of Boston University and the first author of the study.
An increase in sweating as it is immersed in the hot VR scene is likely to explain the difference, helping the body to cool more efficiently during exercise, the researchers explained.
In fact, participants sweat about 20 grams more when exposed to hot landscape than when looking at the frozen, providing an additional cooling lifting for their bodies.
Researchers suggested that future studies may investigate VR as a cost effective tool to help workers in extreme heat adapt faster, potentially increasing their health and safety.
“Athletes or military personnel may be able to train for more extreme environments without having to travel physically in these areas,” Ragland said.
Human number of overheating
A healthy body temperature usually ranges between 97.6 ° F and 99.6 ° F. But when your inner thermostat adheres very high – either due to exposure to heat, fever, intense exercises or other causes – can become rapidly dangerous.
There are three main types of heat -related diseases, according to Johns Hopkins.
Heat jumps are the milder forms, which include painful muscle cramps and spasms that occur during or after intense physical activity in hot conditions.
Heat fatigue is more serious. Occurs when the body loses large amounts of water and salt through severe sweating, often after prolonged time in heat or strong physical activity. Symptoms include muscle cramps, pale and clumsy, nausea, vomiting, headaches, fatigue, weakness and anxiety.
Heat stroke is the most severe – and potentially deadly. This medical emergency occurs when the body temperature regulation system becomes overwhelmed, pushing the essential temperatures to 104 ° F or higher.
Warning signs of heat stroke include hot, dry, sweating -free skin, a rapid heartbeat, nausea, vomiting, headaches, confusion, agitation, seizure hallucinations – and in extreme cases, coma or death if not treated.
Overheating? Cold – quickly
If you start to overheat the middle midday session-if you are in the gym or grind it under the sun-prolt pause immediately.
The Mayo Clinic recommends finding a shady place or going to an air conditioning space to help lower your body.
Moisturize with water or a sports drink, and strip any extra layer. If you are still baking, ride in a cold shower, dip in a fresh bath or press the ice pack, wrists and armpits.
If the symptoms are not relieved within an hour, it may be heat exhaustion – or even heat stroke. Don’t tough it. Get medical help quickly.
