Oxytocin “the feel-good” hormone”





Oxytocin “the feel-good” hormone”

Oxytocin has other benefits as well like making you feel more aroused, increasing feelings of trust, lowers heart rate, reduces blood pressure and simply makes you more ready for sexual interaction. 
Skin to skin touching (with intimacy, a massage, intercourse, or cuddling) is all that is required. Also involved in sexual responsiveness and orgasm, the hormone oxytocin counteracts stress and depression by combating the harmful effects of cortisol and reduces blood pressure. It has also been shown to improve gut motility and decrease intestinal inflammation.

One of the most prevalent benefits of sleeping naked is that it let’s your body cool properly at night better. Doing this helps to maintain healthy (more balanced) cortisol levels. Cortisol is also known as the stress hormone as i’m sure you’re aware. The higher your cortisone levels the more you are at risk for certain health conditions. Conditions like high blood pressure, higher than optimal cholesterol levels, as well as other imbalances, weaker immunity and increased appetite which is weight gaining effects. Cortisol is also a fat storing hormone so the higher your cortisol levels the more your body will store fat. The cortisol levels in the body are usually lowest when you are sleeping deeply  (between 10 p.m. and 2 a.m or so) But after deep sleep your cortisol levels start to rise again in order to wake you up in the morning. Want to lower your stress levels and help the body release fat stored by cortisol? Sleeping naked is a step in the right direction. Sleeping naked keeps you cool which helps cortisol levels.

Sleeping naked does in fact stimulate oxytocin which is a feel good hormone. This is also known as the “love hormone” which also happens to be released when you are experiencing sex and orgasm. It is a hormone that helps fight depression as well as contributing to gut health and a healthy blood pressure levels. Sleeping naked with your partner can light the flame and increase your sex-drive and physical connection.

When we sleep in total darkness, melatonin is released, triggering a very slight but critical cool-down in the body. As body temperature drops, growth hormone is released and works its regenerative magic.


6 amazing health benefits of sex in a loving relationship
Majority of relationship therapists will tell you that not having sex with your partner frequently enough (at least twice a week) will make either or both of you unhappy, frustrated, depressed. Research shows people who have intercourse (not masturbation) at least once or twice a week are better placed to live longer due to the companionship, happiness and pleasure they both bring.
One passionate sex session and all your problems are gone.

1.      Sex helps your heart: Having sex at least twice a week will heavily reduce your chances of having a heart attack and helps maintain a healthy heart.

2.     Sex relieves stress and tension: This is because the feel good hormones – endorphins and oxytocin – are released during sex.

3.     Sex relieves pain: Studies show that after you orgasm, the hormones released will actually help stop your pain; headaches or any other body pains.

4.     Sex makes you feel and look great: The more sex you have the more hormones like testosterone and estrogen are released into the body and this helps keep your body looking young and fresh. If you want softer skin and shiny hair, then estrogen is your answer.

5.     Sex helps you sleep better : A relaxed sex session, which results in an orgasm, will release the hormone prolactin. This is the hormone that is heavily linked to a good night sleep.

6.     Sex fights disease: People who have frequent sex have a higher level of an antibody called immunoglobulin A (IgA). According to research, these antibodies help combat diseases

Moving Bed Biofilm Bioreactor (MBBR) -Design and Construction Principles of FMR






Moving Bed Biofilm Bioreactor (MBBR) process uses the whole tank volume for biomass growth. It uses simple floating media, which are carriers for attached growth of biofilms. Biofilm carrier movement is caused by the agitation of air bubbles. This compact treatment system is effective in removal of BOD as well as nitrogen and phosphorus while facilitating effective solids separation.

Design and Construction Principles

MBBR units are placed in series based on the load entering each reactor. Neutralised and settled wastewater passes through MBBR for reduction in BOD/COD. Most of the MBBR plants are provided with vertically or horizontally mounted rectangular mesh sieves or cylindrical bar sieves. Biofilm carriers are made up of high density (0.95 g/cm3) polyethelene. These are normally shaped as small cylinders with a cross inside and fins outside. The standard filling of carrier is below 70% with a maximum specific area not more than 465 m2/m3. Generally, design load for COD-BOD removal is 20 g COD / m2d. Smaller carriers need smaller reactor volume at a given loading rate (as g/m2d) when the carrier filling is same. 

It is advisable to use MBBR in combination with a septic tank, DEWATS or a pre-coagulation step as a pre-treatment unit, depending on the local conditions and input characteristics. It is a very robust and compact alternative for secondary treatment of municipal wastewater, having removal efficiency for BOD 90 – 95% (low rate) and that of 75 – 80% for high rate. Average nitrogen removal is about 85%. There is no need for sludge recirculation. Phosphorus and faecal coliform reduction is feasible with additional passive (non-mechanical) or active (mechanical) system components.

A constantly operating MBBR does not require backwashing or return sludge flows. It has minimal head-loss. Coarse-bubble aeration in the aeration zone in the wastewater treatment tank provides ease of operation at low-cost. Agitation continuously moves the carrier elements over the surface of the screen thus preventing clogging. Maintenance of MBBR system includes screening, influent equalisation, clarifier system, sludge handling and integrated control system. There is no need to maintain f/M ratio as there is self-maintenance of an optimum level of productive biofilm. Skilled labour is required for routine monitoring and operations of pumps and blowers.

You always need expert advise to design a efficient and cost effective system.
