Even in hot or cold conditions. Every Muscle Movement generates hate and our body takes advantage of that fact to warm up when its cold. Shivering means the bodies heating system is kicking in. In addition, the blood vessels of the skin constrict so that less heat is lost into the air. Many people feel most comfortable at temperatures around 20 degrees celsius fast because the heat, the body produces at rest is enough. It doesnt need to do anything to heat up or cool down at higher outside temperatures. The Heat Transfer with the environment stops working so well. Instead, another cooling system in the body is activated sweat beads come out of the pause to moisten the skin. As they evaporate, they use heat energy in the process which cools down the skin. If our internal temperature rises, the body tries to transport the heat to the surface as quickly as possible. The heart starts pumping faster. At the same time, the body loses fluid, the blood volume decreases and the brain is not supplied properly. That leads to a headache and dizziness. If the air around us is not just hot but also very humid, it cant absorb as much moisture. Then even heavy sweating provides little cooling.

Having a glass of water on your desk and help says muscle. Shoreline is about, you know, how much water we need varies according to age and older people might not need as much as one leader could be enough, including all drinks. But when its hard or when were working, we sweat more.

If we lack water, our blood starts to thicken, and the heart has to work hard in our kidneys, need water to flush out toxins and keep our blood clean. If we drink too little, our brains found the alarm when its finished clean. If we dont drink enough, and if we get overheated when we get a headache, what we feel nauseous, sometimes we have to vomit, and we cant even get confused yet, and our temperature can keep rising or the temper, it can become very serious. So fatal. What should we drink . Who soft drinks are not good for flaking on thursday, because they often are packed with sugar and calories.

We start to sweat in order to cool down during 2. 00 to 3. 00 average sessions in the sauna, we lose up to a leader of water. The high temperatures stimulate the bodies metabolism. The heart begins to beat more quickly. The blood vessels widen, and Blood Pressure drops. Dousing yourself in cold water causes the blood vessels to then constrict. Suddenly, Blood Pressure rises again, making it a kind of training for the cardiovascular system to waste us a good faith through the vascular training in the sauna.

Climate change doesnt just cause extreme heat. It also increases our exposure to ultraviolet light. Few clouds means more exposure to sunlight and more days with high a u. V levels. The us own layer, which at least partially shields us from uv, radiation is very thin and places. And those depleted areas allow 3 more rays, that means our skin is particularly vulnerable. How can we best protected admittedly, this might be a bit over the top, but the w h joe says skin cancer cases have rocketed in recent years. Per milla noma. A new study indicates that by 2040, the numbers could rise globally by almost 50 percent. Its time to take Sun Protection seriously. The suns uv rays damaged the dna inside skin cells. Its the main cause of skin, cancer and skin ages. Lets answer the most important questions about Sun Protection and health. Theres only fair skin, the Sun Protection, which is is that everybody should be wearing sunscreen. Christopher munich, professor of dermatology at yale school of medicine, and an expert on sunscreen. One of the things that i like telling my patience is that the skin remembers all the sun it ever cease. And if you think about it that way, the sun you get as a child at sun, as you get you get as a teenager, the sun, you get as a young adult and then an older adult. All of that. Humans have sun exposure matters. When it comes to wrinkles, aging pigmentation change of the skin and risk of skin. Cancer dermatologists therefore recommend using Sun Protection daily, at least on uncovered skin areas such as the face and hands. I love, i tell all my patients to use it all year round. Even when the sun is in tile, turn done. Yellow will rebate home grin . Is it dermatologist who posts about skin care on instagram . It might me say maam, in my comparison is when i drive to minutes, my car to buy bread at the bakery. Do i have to use the seat belt, even though its just 2 minutes for her . Yeah, im not a one thing once im, you always have to protect yourself no matter what length of journey. Its the same with some protection is furniture. Uv. Radiation also damages, darker skin, and can cause skin cancer. Although its been scientifically proven that uv radiation increases the risk of cancer in fair skin to people. The link is less clear cut for people with dark skin, where genetic factors could play a greater role. Is sunscreen, unhealthy . There are always reports that sunscreens contain harmful substances. How true is that . First of all, there are 2 types of sunscreens. Those with chemical filters and those with mineral filters. Chemical filters form of film on the skin that absorbs uv, radiation converts it into heat, and then releases it into the environment. Mineral filters contain small particles that reflect uv rays, thereby protecting the skin. But these particles in the mineral filters leave a visibly white film on the skin. To let me see a tiny hold on for young children, for example, i recommend Mineral Sunscreen because i can keep better check on my children. If i see that covered in white, for example, and that completely safe mental sunscreen is also better tolerated if you have contact allergies. It does not have that mule u. V. Filters are listed in the ingredients as zinc oxide or titanium oxide and chemical sunscreens of frequently used u. V. Filter is octo cry lean. The substance has been controversial since a study from 2021. So the idea is that there is some research that shows that octo cry lead to can break down over time into something called benzo for know and benzo for known has been shown to be a low level carcinogen as well. Meaning it can cause cancer and certain situations as well as it can disrupt that indifferent system, meaning that it yet can mess with kind of hormones in the body. This chemical conversion happens when sunscreen containing arctic riling gets warm or old. So its better not to use last years. And e, u Expert Committee still considers cosmetics containing after cry lean to be safe. Not every one is convinced. I think that there is enough data out there to raise the concern. And so thats why i tell patients, look in the future. May it be proven that dr. Climbing based on springs for say yes, him might be. But right now there are some questions in the science, isnt there yet . So maybe take some precaution and just stay away from doctor crime by sunscreens. But not all chemical uvie filters are harmful, completely avoiding sunscreens for fear of certain substances is the worst thing to do. Some protection is better than no protection. So regardless of what the products out there is, not enough evidence linking any of these problems, saying that 100 percent they caused this. But we do know that sun burns will leave the skin cancer. So that parts proven, so how much sunscreen is enough. Sunscreen only protects you if you use enough of it. The rule of thumb is 2 milligrams per square centimeter of skin. Its relatively easy to measure with a teaspoon. You should use that much on your face alone. Your entire body needs just under 6 teaspoons of sunscreen. Experts recommend a Sun Protection factor of at least 50. The most important thing is remembering to reapply. I think that what happens to most people, especially if theyre swimming or if theyre united feature a pool, they forget to reapply. I tell patients what every 2 hours you need to be re apply. So you should get through 100 milliliters during a day in the sun. Still sunscreen alone cant fully protect you. So. So nickelodeon, avoid the sun, lie in the sun, enjoy the sun waving a sun hat and always fit in the shade. Dont let the Children Play in the blazing sun is not valid or not even lawful. And by the way, theres no such thing as healthy channing. Every time you get a tear, not just a sunburn, but tanning that is a reaction of the skin to excessive sun. Sunscreen also helps fight wrinkles and aged bought. It prevents what no anti aging cream can undo. So remember using of sunscreen and reapply it every 2 hours, dispose of sunscreen after 6 months, and avoid direct sunlight if possible. And if he wants to know exactly how high the u.

Its helped a lot because you can see the previously affected areas are as good as gone in a few months. So have to repeat the therapy cycle. Meanwhile, medical technologist, how, but please go and his assistant are continuing to take measurements. Uv radiation is yet another positive effect. Yet some, some in the summer we always see a lower incident of viral illnesses. That can certainly of something to do with solar radiation, although there are of course, several factors involved. But natural uv be radiation and uva radiation both co viruses, so you know, we couldnt live without the sun. It cheers us up and has other positive effects. But of course sunlight should only be enjoyed in moderation if youre outside for more than about 20 minutes. Be sure to apply sunscreen. A now for a new exercise, be a walk out.
