And in the grip of that all moves, or do you have an adolescent son who is flaking out and getting weird. This is puberty and its all about homewards. So hormones have a bad chip potations messing everything up, but is this the only to the world . Lets hide out almost messenger substances that control a lot of lead of all the pop ways. And there are plenty of hormones. So lets focus on a tiny sample. And what they could do for you slip and youre on the brink of a life and death that we can often count on adrenaline. The hormone is released by the adrenal gland in response to stressful situations. It spreads rapidly through the body via the plunge stream. For a few short moments that the still is veritable superpowers. But soon after, the effect wears off. Other hormones have a much longer impact. So much rope and it helps to grow. d estrogen and testosterone influenced sexual development, as well as our physique and monotone and affect our state cycles. Apart from the adrenal gland hormones are released from the pancreas and the kidneys, the testicles or ovaries, the imus, the guy, right, and the gland. The pituitary gland is found at the base of the brain and is responsible for hormonal regulation. Hormones are an important means of communication between me and mine. Just think about what happens to us when we fall in love. Just thinking about our beloved can give us butterflies cause us to lose our appetite or set our pulse racing and give us sleepless nights. Hormones such as dopamine and phenol ethylene are responsible for such feelings. A solid relationship makes us calm and relaxed thanks to higher levels of serotonin. Physical contact releases, oxytocin, which fosters a sense of trust between partners suffering. A broken heart has the opposite effect. Oxytocin levels drop as just dont mean as we gradually lose heart and become a far chick hormones play a central role in our lives. They help us to attain our goals and reward us with positive feelings. Even if its not always clear whether we control our hormones or if theyre in charge of us all moments decide nearly everything in our life. If we would see a full, if were tired, if were hungry, if all hair falls out already, we feel like having sex. Our hormones are constantly on the move. Theyre going up, theyre going down. Theyre going up again. Not only in the cause of the day, but in the cause of a lifetime. This is especially evident in puberty with boys and girls having difficulties coming out of bed in the morning. But for us adults, instead of getting annoyed by this, we should watch the next report. Its 8 oclock in the morning for germanys high school as thats when the day gets started. Or least it used to be i was still at home. Yes, i dont go in until a bit later when im more awake, then i can actually take part. If i went in for 1st period, id be useless. But the new approach at this school allowing students to work by themselves in the 1st 4 periods means he only needs to go in when hes in a fit state to learn. Theres a teacher on duty to help and to supervise, but the students decide the schedule themselves and can stay home for the 1st few hours if they want to have in effect, is a chronic biologist. And believes the system can be a huge help to teenagers. As of us begin, now, we know that from puberty, young people start going to bed and waking up later until theyre 20 or 22, when they sleep pattern changes again. In the course of our life time, we go back to a pattern of going to bed and waking up earlier for the young people usually have to get up early, even though theyre going to bed late and state and absent. So they end up with a serious sleep deficiency. Ringback and when theyre in math class at school, its basically their biological night time. And the teenage sectarian rhythm means that even if they try getting to bed early and they cant fall asleep, that body clock keeps them up. When the alarm goes off in the morning, it interrupts their Rapid Eye Movement sleep. The render things plays an Important Role in processing information and emotions. Going out of how we know that sleep deprivation is closely linked to alcohol dependency extreme fatigue and concentration difficulties. Its also a factor in high risk behavior. Teenagers are more vulnerable to traffic accidents. They have more difficulty learning and their depression rates are high and the School Grades suffer the cost and has avoided this fate. His high school doesnt want teenagers, acadia rhythms to impede their performance and has taken the pioneering step of only scheduling tests and exams. Later in the day. For a number of studies have shown that people who are late chrono types, in other words, people, his internal clock tells them to go to bed late. I had a disadvantage in school and especially when it comes to exams, it makes a difference. What time the exams take place is that if the exams are early, its bad for late chrono types, but not teenage bodies release hormones that affect their biological clocks, pushing them to stay up for my work best. If i go to sleep around 10 or half past 10 and then dont go to school until 2nd period and something that makes the whole day much easier. And thats what matters. Its about how the day starts. Its really great that we decide for ourselves when we start. It puts you in a better mood. Its been fun unfinished. Its like im off. My grades have really improved. I was actually surprised by how much of a difference it makes is i dont want to eat, definitely prefer this system better for me. So i am a students ability to absorb information and concentrate depends on the time of day if they want teenagers to learn efficiently. Schools need to factor in that rhythms reading and were not talking about Elementary School children or 10 or 11 year olds. This is a problem affecting teenagers, they should only have to go to school later in the day. Scientists have been saying that for decades, but so far, few schools here in germany have taken note of, is there such a thing as hormonal, selfdetermination, this is the topic of onyx talk and i will send our medical report out to frank, a paragon of high medical peter, here my questions are meeting dr. Frank, our partner on the new scientist and wrote a book about hormones. Hello, how are you feeling fine . I mean, thats fine if anyone can feel these days, but its a beautiful day. And that humor surgery or your hormones, well, they are certainly influential. And if you look at the sun, for example, that will raise my serotonin levels, which will help me, for example, to suppress a desire, the because sort of tone is really good at suppression. So of course, hormones flay an Important Role in how we feel. For instance, i like to think about them like music problems have a very bad repertory from their tribe america. Bricks were from our life. Difficult for us. Are you right when things no it luckily not the idea that halmos somehow like a disturbance in allah system comes from this very. We have the idea that we are these rational beings who make rational decisions all the time. And ill wrestle decisions. I great decisions. Even though, i mean have you seen people also, other systems arent that great, even the most rational ones. We can lie to ourselves. We can over excedrin chances we can get the wrong idea or just not think far enough. So basically, already our idea of all brain is slightly overrated. Lets talk about the bitch or the dust that we really come up with. Likely not in the end. You can say that they are a necessity halmos on the sets of the but theyre not enough to make the decision. So basically they will push you in a certain direction. For example, if you think about sex, they will make you feel less or maybe feel your impulses stronger and weak of it. The path that tells you not to dance too much or to take back and keep back. But in the end, if you act on your impulses, thats your own decision. Thats your brain making these decisions. And so we cant hide behind the homes, save as the tip of the iceberg can hide off the rest of the iceberg. We all want because its all part of us. There are thousands of forms. But 2 of them, Everybody Knows a surgeon and toaster store and a sort of room in thrones with the woman and toast, the throne room when it is the suit, sir . No, of course not. And its shocking, frankly, how often we still find that in you tube videos, telling man how to suppress a estrogen, how to use it to stuff strong and so on and so on. So 1st of all sex hormones and as binary, as we think, and neither sex us, frankly, basically testosterone and estrogen as was tributed across all that and us and sexes. We cant even say that if we meet a woman, she necessarily has a higher estrogen levels on everest. Yes. But the same goes for testosterone levels. These change was all lifetime and they change also from the morning to evening. So there is not this one being influenced by just all stone and another one by estrogen. Another interesting homeowners looks at the car to go home. It is so we have circular and we cut it with someone and it makes a speech for and cozy. On the other hand, it makes the new how does it fit together . Yeah, thats another with these examples where we have an idea of how the world should be and that we should either stuff the homeowner into that very narrow idea or have our idea of a lot of us on the spot. Ok, this must be cuddly and romantic at the same time. Even though if you look at love on the home, a level is very different thing than these very exciting times that i will revolt it through, around stress, all moans and also serotonin. And theres this cozy pot to which oxytocin also belongs the path where we feel restful without patna. And while we enjoy being together, im just letting go of regenerating. But as everyone knows who, for example has a dog. When dogs have puppies, you dont go so close by because youre going to get bitten probably. And thats an important part of love that were protecting the ones we love. So im not sure why we are so surprised that a homo thats involved in love would also be involved sometimes in aggression and sensitivity to threats. You have wrote a very interesting book about romans, about or mysterious miracles, the substances an old brain of old blot. What you should read, you know, about or i think the most important take home message for the book was for me to be less worried of all the things that our homes do with us. And think more of all the things that we do to all homes without they rescheduled was all fills was all the stuff were doing it never really thinking about the question shouldnt be, how do we eliminate these home will affect how do we eliminate all homes the question should be, where is this point that when does it harm us and how do we find this point . And then we can also help people or help ourselves reach it. But for that we really need to drop the idea that homeowners in general are bad. I see a lot to do for side
