Top 8 Health Benefits of Sex

Sex not only helps you sleep well, relieve stress and burn calories, there are also several other reasons why you need to have sex more often. 

Improves cardiovascular health A recent study says that men who have sex more than twice a week, have a lesser risk of getting a heart attack, than men who had sex less than once a month. 

Increases immunity Regular lovemaking increases the level of the immune-boosting antibody immunoglobulin A (IgA), which in turn makes your body stronger against illnesses like the common cold and fever. 

Reduces stress Stressed out with work or family problems? Don't let it affect your performance in the bedroom. Not only will having sex improve your mood, but a study has also proven that folks, who indulge in regular bedroom activities can handle stress better and are happier people. 

Relieves pain If you're using a headache as an excuse to not make love, stop doing that. Have sex instead, because, when you're about to have an orgasm, the level of the hormone oxytocin increases by five times. This endorphin actually reduces aches and pains. 

Promotes longevity When one has an orgasm, a hormone called dehydroepiandrosterone is released. This improves immunity, repairs tissue and keeps the skin healthy. Men, who have at least two orgasms a week, live longer than men who have sex just once every few weeks. 

Increases blood circulation Because your heart rate increases when you have sex, fresh blood is supplied to your organs and cells. While used blood is removed, the body also expels toxins and other materials that cause you to feel tired. 

Improves overall fitness If you find going to the gym mundane or working out at home a task, here's another way to help you lose the flab and keep in shape. Regular sex will do wonders for your waistline. Half an hour of lovemaking burns more than 80 calories. 

Increases levels of Oestrogen and testosterone In men, the hormone testosterone is what makes them more passionate in the sack. Not only will it make you feel way better in bed, but it also improves your muscles and bones, keeps your heart healthy and keeps a check on your cholesterol. In women, on the other hand, the hormone oestrogen protects them against heart disease and also determines a woman's body scent.

Branches Of Trigeminal Nerve

Trigeminal nerve is the largest cranial nerve which comprises of three branches. Two of which are sensory except Mandibular nerve which is a mixed nerve and the largest branch of the fifth cranial nerve.

V1 (Opthalmic)
V2 (Maxillary)
V3 (Mandibular)

Branches of these three divisions:-

1. Opthalmic Nerve:-

Frontal: Supratrochlear and Supra orbital.

Nasociliary: Posterior ethmoidal, Anterior ethmoidal, Long ciliary, Nerve to ciliary ganglion, Infratrochlear.

Lacrimal: Supplies lateral part of upper eyelid, secretomotor to lacrimal gland.

2. Maxillary Nerve:-

In Middle Cranial Fossa:

Meningeal Branch (Nervous Spinosus).

In Pterygopalatine Fossa:

Ganglionic branch.

Zygomatic: Zygomaticotemporal and Zygomaticofacial.

Posterior Superior Alveolar.

In Infraorbital Canal:

Middle Superior Alveolar.
Anterior Superior Alveolar.


Infraorbital: Palpebral, Labial, Nasal.

3. Mandibular Nerve:-


Meningeal Branch (Nervous Spunosus).
Nerve to medial pterygoid (supplies medial pterygoid, tensor veli palatini, tensor tympani).

Anterior Division:

Deep Temporal
Lateral Pterygoid

Posterior Division:

Inferior Alveolar.

Ayushmann Khurrana has OCD!

A new name added to the list of celebrities having OCD. Ayushmann Khurrana (Bollywood Actor and Singer) has got ocd about hygiene.

On an interview with a news paper he told about his secret, showing his clean hands and nails, said, " I have an OCD (Obsessive Compulsive Disorder) for cleanliness. I wash my hands umpteen number of times. He also revealed that he carries a dental kit and brushes his teeth three to four times a day. "It is a good OCD to have, as I don't have to go for manicure. My wife also likes this fetish in me," he laughs.

So what do you think is it necessary to have OCD for being celebrity?

Watchig porn could cause brain shrinkage!

 It could sound a little weird, but a new research found an association between porn watching and brain shrinkage.

  1. Study showed striatum was smaller the more porn someone had viewed.
  2. The striatum is a brain region linked with motivation and reward response.
  3. This is the first direct link between pornography and a lack of motivation.
  4. Researchers said it is not clear whether watching porn leads to brain changes or whether people born .with certain brain types watch more porn.

Men who watch pornography may be shrinking their brains and dulling their responses to sexual stimulation, a study has found.It is the first time researchers have found a possible link between regular viewing of pornography and physical harm.However, an alternative explanation is that people who spend more time looking at pornography are born with a certain type of brain.

Dr Simone Kühn, the study’s lead author from the Max Planck Institute in Berlin, said it was the first evidence for a link between porn consumption and reductions in brain size and brain activity in response to sexual stimuli. But the study can’t prove porn-watching causes changes to the brain.People who already have a smaller ‘striatum’ (the reward part of the brain) may be more likely to use pornography.

Classification Of NSAIDs (Non Steroidal Ani Inflammatory Drugs)

Nonsteroidal anti-inflammatory drugs, usually abbreviated to NSAIDs are a class of drugs that provides analgesic (pain-killing) and antipyretic (fever-reducing) effects, and, in higher doses, anti-inflammatory effects.

The term nonsteroidal distinguishes these drugs from steroids, which, among a broad range of other effects, have a similar eicosanoid-depressing, anti-inflammatory action. As analgesics, NSAIDs are unusual in that they are non-narcotic and thus are used as a non-addictive alternative to narcotics.

NSAID identification on label of generic Ibuprofen an OTC NSAID. The most prominent members of this group of drugs, aspirin, ibuprofen and naproxen, are all available over the counter in most countries.[1] Paracetamol (acetaminophen) is not considered an NSAID because it has little anti-inflammatory activity. It treats pain mainly by blocking COX-2 mostly in the central nervous system, but not much in the rest of the body.

NSAIDs inhibit the activity of both cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2), and thereby, the synthesis of prostaglandins and thromboxanes. It is thought that inhibiting COX-2 leads to the anti-inflammatory, analgesic and antipyretic effects and that those NSAIDs also inhibiting COX-1, particularly aspirin, may cause gastrointestinal bleeding and ulcers. For this reason, the advantages of COX-2 selective inhibitors may be indicated.

Cervical Plexus Mnemonic

Cervical plexus: arrangement of the important nerves “GLAST”:

• 4 compass points: clockwise from north on the right side of neck:

- Great auricular
- Lesser occipital
- Accessory nerve pops out between L and S
- Supraclavicular
- Transverse cervical

Chemicals Responsible for love!

Falling in love causes body to release flood of feel-good chemicals (hormones) that trigger specific physical reactions. These chemicals are responsible for making our cheeks flush, our palms sweat and our hearts race." Levels of these substances, which include dopamine, adrenaline and norepinephrine, increase when two people fall in love.
Dopamine (A Neurotransmitter) creates feelings of euphoria while adrenaline and norepinephrine are responsible for the pitter-patter of the heart, restlessness and overall preoccupation that go along with experiencing love. MRI scans indicate that love lights up the pleasure center of the brain. When we fall in love, blood flow increases in this area, which is the same part of the brain implicated in obsessive-compulsive behaviors.
"Love lowers serotonin levels, which is common in people with obsessive-compulsive disorders. The phrase 'love is blind' is a valid notion because we tend to idealize our partner and see only things that we want to see in the early stages of the relationship. Outsiders may have a much more objective and rational perspective on the partnership than the two people involved do.
