If You Smell Funky Asparagus Pee, You Have This Special Gene

If You Smell Funky Asparagus Pee, You Have This Special Gene

Have you ever eaten asparagus and noticed how it changes the way your pee smells? You may have heard about the phenomenon but wonder why it seems to affect some people and not others.

Many researchers agree that the smell of asparagus pee results from the metabolism of a compound found exclusively in asparagus known as asparagusic acid. The compound is broken down into sulfur-containing compounds such as methanethiol, dimethyl sulfide, and dimethyl sulfoxide –which are responsible for the most prominent odor detected in asparagus pee. All of the above components can easily vaporize into a gaseous state at room temperature [1] –which brings them to your nose.

Why can’t some people smell it?

The whole asparagus pee smell issue is a little complicated. Various theories attempt to explain why only some people can detect the odor in their pee after eating asparagus. Some researchers suggest that people who don’t detect the asparagus smell in their pee do not have the ability to produce the scent; others argue that everybody breaks down the asparagusic acid in the asparagus equally, only that some people simply lack the ability to detect the smell.

M Lison and other researchers [2]carried out a study to explore this phenomenon back in 1980 and discovered that actually everyone produces this “asparagus smell” but only a few people were able to smell it. The study also revealed that people who were able to detect the smell could even smell it in the urine of those who could not smell it. This reinforced the idea that the difference in the two groups of people was more as a result of perception than production.

Another study published in the Oxford Journal [3] throws in yet another interesting twist. The study revealed that there still existed some differences even within the groups of subjects who could detect the smell and those who could not. Nevertheless, most scientists generally seem to back the theory that perception is the main reason some people are not able to detect any difference in the smell of their pee after eating asparagus.

Could the variation be genetic?

A DNA-sequencing company (23andMe) carried out an investigation in 2010 to find out if the ability to smell asparagus pee was linked to any genetic component. The study asked subjects if they could detect any odor in their urine after eating asparagus, and investigated the genetic similarities in the two groups. Findings revealed that the ability to detect the asparagus smell was linked to a certain DNA sequence that varied among different people. This means that a single mutation in the genes responsible for smell [4] may be the reason some people are unable to smell asparagus odor in urine.

When all is said and done, it’s important to mention that only about 25% of the population seems to have this unique DNA sequence that allows them to smell asparagus pee. So basically, you do not need to worry about a thing; if you are able to smell the funny scent in your pee after eating asparagus, you’ve got a good nose and can be proud of it.

10 Benefits of Sleeping Naked You Probably Didn’t Know

10 Benefits of Sleeping Naked You Probably Didn’t Know

Sleeping is one of the most important things we do every night.

Getting the right amount of sleep has an untold number of health benefits and not getting enough sleep is a serious problem in many countries around the world.

So you should have heard of the many benefits of getting adequate sleep, but did you know that you can get additional benefits by sleeping naked?

Here are some benefits of sleeping in the nude:

Video Summary

1. It is easier.

When you don’t have to worry about sleeping in clothes, things start to get easier. You don’t have to buy pajamas, which can save you money. You have less clothes to wash and less clothes to put away. You may have to clean your bed sheets more often, but not nearly as often as you’d have to wash your pajamas when you run out.

2. It forces you to be ready to go more often.

Some people get off of work, change into their pajamas, and use this as an excuse to stay home the rest of the evening. This can lead to a more sedentary lifestyle, which has been attributed to things like weight gain.[1] When you keep your regular clothes on, you tend to go out more often and that’s a good thing.

3. It can make you feel happier and more free.

Just imagine the feeling of laying in bed naked. You’re free of your pants and underwear. Women, you’re not wearing a constrictive bra. It’s just you sandwiched between two cool sheets. The feeling just makes you want to smile and it makes you feel more free. Everyone can use that kind of good feeling every now and then, and it may even help you be happier as a person.

4. Skin-on-skin contact is the best.

    If you’re married, or living with your significant other, sleeping naked gives a greater chance of skin-on-skin contact, especially when it comes to cuddling. This kind of contact can also lead to a more active sex life. All of this releases copious amounts of oxytocin, which is the neurotransmitter that helps you feel those good feelings about your significant other.[2]

    5. It could lead to better sleep.

    Let’s revisit the scenario I described above. There are no drawstrings or clothes getting tangled in sheets. You don’t have to worry about shirts getting twisted. All of these distractions go away when you sleep naked and it may help you get better, deeper sleep. You don’t need science to tell you that better, deeper sleep only helps you be healthier.

    6. It can help your skin.

    For once your body gets to breathe. Your private parts, armpits, and feet are generally restricted all day and are often covered by multiple layers, even in the summer time. Give those parts a chance to air out and breathe. This can lower the risk of skin diseases, like athlete’s foot, that result from wet, restricted skin.[3]

    7. It helps you regulate your cortisol.

    Cortisol is a very strange chemical in the body but it can do a lot of damage. When you sleep naked, it helps keep your body temperature at the optimal ranges so your body can better create cortisol. If you sleep overheated your cortisol levels tend to stay high, even after you wake up. This can lead to increased anxiety, cravings for bad food, weight gain, and more terrible things.[4] Sleep naked so you can keep your body temperature down and sleep well so your body can properly produce and regulate cortisol.

    8. It balances your melatonin and growth hormone.

    Continuing along that same vein, keeping your sleeping environment below 70 degrees (F) every night can help your body regulate its melatonin and growth hormone levels. These chemicals help the body do things like prevent aging and are essential to good health. When you sleep in clothes, your body heats up and prevents effective use of these hormones. In other words, sleeping with clothes on makes you grow old faster.

    9. It can keep your sex organs happier.

    For men, the cooler sleeping conditions allows your testes to remain at a cooler temperature. This helps keep your sperm healthy and your reproductive systems functioning as normal. For women, the cooler and more airy sleeping conditions can actually help prevent yeast infections. Yeast grows better in warm, moist conditions.[5] When it’s cooler and dryer, the growth of yeast is prevented.

    10. Sleeping in the summer is more bearable.

      Summertime is a tricky time to get good sleep. If you don’t have air conditioning, then you may find your bedroom a bit stuffy at night.

      Shedding those bedtime clothes can help the bedroom feel more comfortable. You may even be able to turn the A/C off on those cooler nights, which can save you a few bucks on your electricity bill.

      Don’t wake up drenched in sweat again because your thermostat is downstairs and the hot air expands up to your bedroom where the thermostat can’t read the warm temperatures.

      Sleep well with your naked body!

      With these tips in mind, it’s time to start taking off your clothes at night!

      Of course, there are times where clothes are preferable. If you are ill or it’s cold outside, then you should sleep with clothes on to help you stay warm and prevent further illness. Otherwise, go commando!
