Recently I have just discovered that a certain amount of the mobile phone frequency can be absorbed by human tissues.

For example, this is the SAR info of iPhone 4s:

Head: 1.180 W/kg 1 g Body: 0.491 W/kg 1g Hotspot: 0.491 W/kg 1 g

http://en.wikipedia.org/wiki/IPhone_4S

so hotspot means a hot spot on human body right?

Then question is:

What are hot spots on human body?


Hot spots on the human body caused by cell phones are caused by the EMF/RF (ElectroMagnetic Frequency/Radio Frequency) emitted from the phones (or any mobile wireless device). (There is much conjecture about the safety of these frequencies and whatnot… That is not what I am here to talk about).

In this case, the term hot spot does not refer to you being a WiFi hot spot! It simply means that since the frequencies are similar to that of a microwave, you will absorb them and they will cause heating internally. These areas will remain warm for a time - whether you can feel it or not, some people can, some can't. Shown here is a thermal image of someone who recently used a cell phone and one who had not.


Male Erogenous Zones You Should *Def* Stimulate During Sex

Consider this your map to male erogenous zones: how to find them and how to play with them to deliver their most intense orgasm. ever.

It&aposs no secret that female-bodied people have some very specific pleasure points on their body and hopefully, both you and your bedroom bae know just where to touch you for a toe-curling climax. Yet you might be surprised to know that your male partner also has some erogenous zones that — when stimulated — can take their orgasms and your sex life to the next level.

"Orgasm is the release of sexual tension, and tension is created through gradually increasing and varying touch and pressure on their passion points," says Claire Cavanah, co-founder of Babeland, a national chain of women-owned sex shops, and coauthor of Moregasm: Babeland&aposs Guide to Mind-Blowing Sex and Sex Toys 101. "Licking and biting with your mouth, then adding in heat or cold sensations by sucking on an ice cube or drinking hot tea will drive them wild."

Follow this expert-backed guide to the key erogenous zones for males and then put your new learnings to good use IRL.


The Most Sensitive Spots on Men (and on You)

Think there&rsquos only one true hot spot on the male body? Well, not exactly. When asked to rate the level of arousal for different body parts, men offered up a surprising variety of erogenous zones , according to a recent study in the journal Cortex. And so did women (although maybe that&rsquos not a huge surprise to you).

Of course, guys rated the penis as the ultimate erogenous zone, while women rated the clitoris as the top spot. But surprisingly, men and women shared a similar continuum of arousal. &ldquoI think the sex differences in erogenous zones have been exaggerated,&rdquo says lead study author Oliver Turnbull, Ph.D., professor at Bangor University in the U.K. Basically, you&rsquore not the only gender that appreciates some attention on your neck and inner thighs. And working your way through each of these erotic areas&mdashrather than going straight for the bullseye&mdashdefinitely wouldn&rsquot be a bad idea, says Turnbull.

Researchers surveyed 793 men and women recruited through colleges in the U.K. and South Africa and asked them to rate each body part on a scale of 1 to 10 in terms of level of arousal (10 being the hottest). Check out the infographic below to find out which spots made it to the top of the male list&mdashplus, the hot zones on your body that deserve a little more attention:

So let&rsquos be real: It&rsquos pretty obvious that guys rank their manhood as way more sensitive than the rest of these areas. But the data suggest that men&mdashlike women&mdashcan get turned on by touch at all of these spots. Click through to find tips on how to stimulate each of his top 10 erogenous zones, as well as how to pleasure your most sensitive spots.

Hot Spots

A hot spot is an area on Earth over a mantle plume or an area under the rocky outer layer of Earth, called the crust, where magma is hotter than surrounding magma. The magma plume causes melting and thinning of the rocky crust and widespread volcanic activity.

2018 eruption on Mount Kilauea.

A hot spot is an area on Earth that exists over a mantle plume. A mantle plume is an area under the rocky outer layer of Earth, called the crust, where magma is hotter than surrounding magma. Heat from this extra hot magma causes melting and thinning of the rocky crust, which leads to widespread volcanic activity on Earth&rsquos surface above the plume.

While most volcanoes form along tectonic plate boundaries, mantle plumes and hot spots lead to their development as well. Hot spot volcanoes occur far from plate boundaries. Because the hot spot is caused by mantle plumes that exist below the tectonic plates, as the plates move, the hot spot does not, and may create a chain of volcanoes on the Earth&rsquos surface. Neither the Hawaiian Islands nor Yellowstone National Park are near plate boundaries. Rather, the volcanoes that form the Hawaiian Islands and the volcanic activity at Yellowstone National Park are due to their locations over hot spots.


3. Inner Arms

The thin, soft skin of the inner arms makes this area ultra-sensitive, according to Sabat. Think about it, how often do you really give attention to your inner arms?

Try this: While most of these erogenous zones can be stimulated through kissing or your tongue, the light, controlled movement of your fingers is especially great for inner arms. Stroke the skin from just inside their inner shoulder and move gently down to the inner elbow, says Sabat. If you and your partner are both into BDSM and have spoken about trying it out, pulling this move when your partner has his arms tied up (either in a fixed T-shape or just with their wrists above their head), can be really sexy too, Sabat adds.


Human subtelomeres are hot spots of interchromosomal recombination and segmental duplication

Human subtelomeres are polymorphic patchworks of interchromosomal segmental duplications at the ends of chromosomes. Here we provide evidence that these patchworks arose recently through repeated translocations between chromosome ends. We assess the relative contribution of the principal mechanisms of ectopic DNA repair to the formation of subtelomeric duplications and find that non-homologous end-joining predominates. Once subtelomeric duplications arise, they are prone to homology-based sequence transfers as shown by the incongruent phylogenetic relationships of neighbouring sections. Interchromosomal recombination of subtelomeres is a potent force for recent change. Cytogenetic and sequence analyses reveal that pieces of the subtelomeric patchwork have changed location and copy number with unprecedented frequency during primate evolution. Half of the known subtelomeric sequence has formed recently, through human-specific sequence transfers and duplications. Subtelomeric dynamics result in a gene duplication rate significantly higher than the genome average and could have both advantageous and pathological consequences in human biology. More generally, our analyses suggest an evolutionary cycle between segmental polymorphisms and genome rearrangements.

Specific zones Edit

Specific zones are associated with sexual response, and include the lips and nipples in addition to areas of the genitals, notably the foreskin and corona of the glans penis, clitoris and rest of the vulva, and perianal skin. [ citation needed ] The rete ridges of the epithelium are well-formed and more of the nerves are close to the external surface of the skin than in normal-haired skin. [1] These zones have a high density of innervation, and may have an efficiency of wound healing and a capacity to stimulate generalized cerebral arousal. [2]

Nonspecific zones Edit

In these zones, the skin is similar to normal-haired skin and has the normal high density of nerves and hair follicles. These areas include the sides and back of the neck, the inner arms, the axillae (armpits) and sides of the thorax (chest). An exaggerated tickle and anticipatory response are responsible for the heightened sensual response. [ citation needed ]

Male Edit

Males can be aroused by stimulation to the sides of the glans and penis, upper side of the glans, the foreskin, the front side of the scrotum, the skin between the scrotum and anus perineum, and around the anus. [3] The prostate gland may be stimulated from inside the rectum, such as by anal sex, or by applying pressure on the base of the perineum near the anus. [4] [5] [6] Men who report the sensation of prostate stimulation often give descriptions similar to females' accounts of G-spot stimulation. [7]

The foreskin has mucocutaneous end-organs extending from the distal margin to the point where hairy skin starts. [8] The thin dermis and minimal subcutaneous tissue results in closely set nerve networks. Vater-Pacini corpuscles are present. The mucocutaneous end-organs are formed after birth, with few in newborn infants and many well-organized endings in adults. [1] Cold and Taylor state in 1999 that the foreskin is primary erogenous tissue. [9] Alanis and Lucidi in 2004 describe this as speculative and unproven. [10]

Female Edit

Parts of the vulva, especially the clitoris, are erogenous zones. [11] [12] [13] While the vagina is not especially sensitive as a whole, its lower third (the area close to the entrance) has concentrations of the nerve endings that can provide pleasurable sensations during sexual activity when stimulated this is also called the anterior wall of the vagina or the outer one-third of the vagina, and it contains the majority of the vaginal nerve endings, making it more sensitive to touch than the inner two-thirds of the vaginal barrel. [12] [13] [14] [15]

Within the anterior wall of the vagina, there is a patch of ribbed rough tissue which has a texture that is sometimes described as similar to the palate (the roof of a mouth) or a raspberry, and may feel spongy when a woman is sexually aroused. This is the urethral sponge, which may also be the location of an area that some women report is an erogenous zone this is sometimes called the G-spot. When stimulated, it may lead to sexual arousal, an orgasm, or female ejaculation. [16] The existence of the G-spot and whether or not it is a distinct structure is debated among researchers, as reports of its location vary from woman to woman, it appears to be nonexistent in some women, and scientists commonly believe that it is an extension of the clitoris. [13] [17] [18] [19]

Mouth Edit

The lips and tongue are sensitive and can be stimulated by kissing and licking. Biting at the lip can also provide stimulus.

Neck Edit

The neck, clavicle area and the back of the neck are very sensitive, and can be stimulated by licking, kissing or light caressing. Some people also like being bitten gently in these areas, often to the point that a "hickey", or "love-bite" is formed. [13]

Ears Edit

Some people find whispering or breathing softly in the ear to be pleasurable and relaxing, as well as licking, biting, caressing and/or kissing it especially the area of and behind the earlobe.

Chest Edit

The areola and nipple contain Golgi-Mazzoni, Vater-Pacini and genital corpuscles. No Meissner's corpuscles and few organized nerve endings are present. [1] There are concentrations of nerve tissue in the area of ducts and masses of smooth muscle. The hair surrounding the areola adds additional sensory tissue. The mass of smooth muscle and glandular-duct tissue in the nipple and areola block the development of normal dermal nerve networks which are present in other erogenous regions and the development of special end organs. The entire breast has a network of nerve endings, and it has the same number of nerve endings no matter how large the breast is, so that larger breasts may need more stimulation than smaller ones.

Intense nipple stimulation may result in a surge in the production of oxytocin and prolactin which could have a significant effect on the individual's genitals, even to the point that some people of both sexes can achieve orgasm through nipple stimulation alone. Having the chest, breasts and nipples stimulated manually (hands), digitally (fingers, toes) and/or orally (mouth, lips, teeth, tongue) is a pleasurable experience for many people of both sexes.

Abdomen and navel Edit

Many people find stimulation (kissing, biting, scratching, tickling, caressing) of the abdomen to be pleasurable, especially close to the pubic region. It can cause strong arousal in men and women, in some even stronger than stimulation of the genitals. The navel is one of the many erogenous zones that has heightened sensitivity. [20] In a 1982 study of eroticism in dress entitled "Skin to Skin", Prudence Glynn claimed that the waist symbolized virginity and that it was the first place that a man would touch a woman "when indicating more than a formal courtesy". [21] [22]

The navel and the region below when touched by the finger or the tip of the tongue result in the production of erotic sensations. [20] [23] Madonna has told in an interview to the SPIN magazine (May 1985 issue), "When I stick my finger in my belly button, I feel a nerve in the center of my body shoot up my spine." [24]

Sacrum Edit

The sacrum, the triangular bone located near the base of the spine, is also an erogenous zone.

The skin of the arms, and specifically the softer skin of the inner arms and across the creased mid-arm bend covering the ventral side of the elbow, are highly sensitive to manual or oral stimulation. Caressing with fingers or tongue, more vigorous kneading, and butterfly kissing can initiate arousal and, in some cases, induce clitoral/vaginal orgasm or penile ejaculation without direct contact with the latter areas. [ citation needed ] The mid-arm bend is especially sensitive due to the thinner skin found there, which makes nerve endings more accessible. [ citation needed ] Arm sensitivity may be reduced or concentrated to a more narrow range by excessive muscularity or obesity on the one hand, or transformed to uncomfortable tenderness by excessive thinness on the other.

Some consider the armpits to be an erogenous zone, despite the similarity of the axillae (armpits) to normal-haired skin in both the density of nerves and hair follicles. Exaggerated or anticipated digital (fingers, toes) or oral (mouth, lips, tongue) stimulation is believed to be responsible for the heightened sensual response.

If pheromones exist for humans, they would likely be secreted by a mixture of liquid from the apocrine glands with other organic compounds in the body. [25] George Preti, an organic chemist at the Monell Chemical Senses Center in Philadelphia and Winnefred Cutler of the University of Pennsylvania's psychology department, discovered that women with irregular menstrual cycles became regular when exposed to male underarm extracts. [25] They hypothesized that the only explanation was that underarms contain pheromones, as there was no other explanation for the effects, which mirrored how pheromones affect other mammals. [25]

The fingertips have many nerves and are responsive to very light touches, like the brushing of a tongue, light fingernail scratching or teeth stroking. The sides of the fingers are somewhat less sensitive and more ticklish. [ citation needed ] Both light and firmer touches work well at the junction of the fingers. Human fingertips are the second-most sensitive parts of the body, after the tongue.

The thighs can be sensitive to touch.

An exaggerated tickle on the back of the legs and knees can also be sensitive for some.

Because of the concentration of nerve endings in the sole and digits of the human foot—and possibly due to the close proximity between the area of the brain dealing with tactile sensations from the feet and the area dealing with sensations from the genitals—the sensations produced by both the licking of the feet and sucking of toes can be pleasurable to some people. Similarly, massaging the sole of the foot can also produce stimulation. Many people are extremely ticklish in the foot area, especially on the soles.


DNA damage 'hot spots' discovered within neurons

Researchers at the National Institutes of Health (NIH) have discovered specific regions within the DNA of neurons that accumulate a certain type of damage (called single-strand breaks or SSBs). This accumulation of SSBs appears to be unique to neurons, and it challenges what is generally understood about the cause of DNA damage and its potential implications in neurodegenerative diseases.

Because neurons require considerable amounts of oxygen to function properly, they are exposed to high levels of free radicals -- toxic compounds that can damage DNA within cells. Normally, this damage occurs randomly. However, in this study, damage within neurons was often found within specific regions of DNA called "enhancers" that control the activity of nearby genes.

Fully mature cells like neurons do not need all of their genes to be active at any one time. One way that cells can control gene activity involves the presence or absence of a chemical tag called a methyl group on a specific building block of DNA. Closer inspection of the neurons revealed that a significant number of SSBs occurred when methyl groups were removed, which typically makes that gene available to be activated.

An explanation proposed by the researchers is that the removal of the methyl group from DNA itself creates an SSB, and neurons have multiple repair mechanisms at the ready to repair that damage as soon as it occurs. This challenges the common wisdom that DNA damage is inherently a process to be prevented. Instead, at least in neurons, it is part of the normal process of switching genes on and off. Furthermore, it implies that defects in the repair process, not the DNA damage itself, can potentially lead to developmental or neurodegenerative diseases.

This study was made possible through the collaboration between two labs at the NIH: one run by Michael E. Ward, M.D., Ph.D. at the National Institute of Neurological Disorders and Stroke (NINDS) and the other by Andre Nussenzweig, Ph.D. at the National Cancer Institute (NCI). Dr. Nussenzweig developed a method for mapping DNA errors within the genome. This highly sensitive technique requires a considerable number of cells in order to work effectively, and Dr. Ward's lab provided the expertise in generating a large population of neurons using induced pluripotent stem cells (iPSCs) derived from one human donor. Keith Caldecott, Ph.D. at the University of Sussex also provided his expertise in single strand break repair pathways.

The two labs are now looking more closely at the repair mechanisms involved in reversing neuronal SSBs and the potential connection to neuronal dysfunction and degeneration.


Is arm pain associated with fibro?

FMS does cause the skin to become hypersensitive. I have times where my hair hurts to touch or brush. It's actually the scalp that is involved. It also happens on other areas of my body. It's a form of paranthesia.

This is one of the classic symptoms of FMS and I hope it comforts you to know it's not unusual, under the circumstances.

I chekced out the site and read it all. it mentions the pins and needle feeling. That's not what I feel, I feel like I have a sunburn on parts of my head. or someone has poured VERY hot water on my head. It only happens on my head.

Now I do get the pins and needles all over my body. used to that. hate it still.

I did bookmark the site to read again. Thanks so much!

Yes, that is what they are speaking of. It's not actually hot to the touch, it's just that sensation of burning.

Have a nice weekend and take care of yourself.

I also get this feeling. It hurts a lot of times to brush my hair (in which is thinning out) as if it is sun burnt. I also get bruises that sometimes bleed on my head.

With me it started years ago (

8 years) with a burning feeling at the base of my neck and in between my shoulder blades in which felt like the skin was thicker there. It also itched in between my shoulder blades, yet as I said feels sun burnt to scratch it.

I get the pins and needles feeling in my body, but not on my scalp. I have a lot of issues with pains all over my body but, have never been told that I have FMS. I do have hypothyroidism, poor circulation and diabetes though in which leaves me thirsty a lot. Also problems with vitamin and mineral issues.

Sorry I don't know what causes it but, I can defiantly relate. Best wishes Me.

Yeah, that's exactly what it feels like. a sunburn! I also have high blood pressure, hypothyroidism and myofacial syndrome. I thought it might be my high blood pressure meds causing it.

And yes!! The feeling between my shoulder blades as in feeling thicker, tingly, and itchy! For years now! Drives me batty. The ONLY thing that relieves my "hot" head and issues between the shoulders is when my hubby massages my head or shoulders.

Now I don't feel like I'm the only one. and I hate that you do understand the "hot" issue. It's not a comfy feeling, that's for sure.

/ Sorry about getting carried away and whining.

I thought a lot about what Breeze said as a possibility for myself. Problem is (with me) FMS or CFS has not been brought up. It sounds right though. You may want to ask your doctor. Best of wishes to you.

Humm my hot spots are different then.

scalp only, mostly right side back towards the crown, I feel like someone burned me yes, or rather more like a hot pokers being pushed down, but yet from the underside. but the skins also hot to the touch, and if I can cool it the pain is lessened.

I dont have any other symptoms as described tho. and no ones given any notice to my comment about the hot spots.
