Men who sleep naked can experience unique benefits

If you are a man that’s been toying with the idea of sleeping naked, this article is for you. Let me explain why. According to scientific research, published by the Journal of Physiological Anthropology, how you sleep is directly linked to your overall health.

Yep, it’s true! Moreover, you can look younger, feel healthier and help place yourself in a better mood by taking it all off before you hit the hey.

Since our earliest beginnings, mankind has slept naked. But because of cultural norms that were largely influenced by shame-based religions, many males moved away from this practice.

Frankly, that’s a crying shame. Don’t you think?

The good news is that in recent years, a shift in thinking has occurred. Part of what’s empowering this change is directly linked to research which points to serious health benefits that men can realize by sleeping in the buff.

Here’s the top 10 reasons based on hard science.


1. You’ll produce more sperm

Scientific research suggests that when you sleep naked, you allow your testicles to produce more semen.

Studies indicate that when you sleep in the buff, you’re encouraging scrotum-homeostasis. That's a 25-cent term that describes your nutsack’s ability to maintain the ideal temperature of 96-98 degrees; the perfect environment for seminal production as part of the testes system.

2. Helps keep weight off

You may think this one to be silly but here me out. When you go to bed in just your bare skin, you help the cortisol levels in your body to stay balanced.

FYI: Cortisol is a biochemical hormone that's uniquely responsible for transmitting hunger pang messages through the brain's stem. When cortisol levels are unbalanced, it can lead to the phenomenon of “stress eating”. If left unchecked, this can cause unwanted weight gain.

3. Greater Intimacy is likely

Guys who sleep in the buff may find that intimacy with a partner increases. Here's why: when your skin touches your mate's, the sex chemical oxytocin skyrockets, according to most sleep experts.

If you've been in a dry spell lately, going nude to bed may be just the ticket to spice things up!

4. Deeper sleep

If you’ve been struggling to get a more meaningful night’s sleep, you may want to consider going to bed without any clothes on.

The reason?

When you’ve got nothing on when your butt hits the sack, a phenomenon occurs where dopamine production is increased. According to science, higher dopamine levels contribute to a sounder, more restful night’s sleep.

5. Less inhibited sexually

Are you sexually conservative? Do you find that you do the same thing, over and over again with your partners? Looking to change that?

If the answer is yes, take off those clothes when you head to bed! Research suggests when you sleep without your underwear on (or anything else), you paradoxically become less inhibited sexually.

Additionally, you may find that during waking hours, you are more open to new and different experiences.

6. Sexsomina less likely

If you get a full night’s sleep, you may keep away a condition called sexsomina. If you haven’t heard of this disorder before, it’s OK. Sexsomina is a new condition whereby a person has sex with others, regardless of person, while in a sleep state.

7. Chases away depression

If you struggle with depression, this health tip is for you. Research suggests that men who sleep without anything on can experience a serious boost in mood. The reasons are biochemical and circulatory in nature and help to avoid hypersomnia.

Hyper what?

Basically, hypersomnia is a clinical condition whereby a person doesn't get enough sleep or sleeps too much – but not restfully. The end result means that your mood crashes during waking hours, causing irritability, frustration and even anger.

8. Anti-aging benefits

If your goal is to look as young as possible for as long as possible, you’ve got to start diving into those sheets without clothes on!

Yep, it’s true!

It turns out that quality sleep, which is encouraged by sleeping naked, increases melatonin.

So what is melatonin? Basically, melatonin is a hormone that’s partially responsible for your wake/sleep cycle, also referred to as circadian rhythm.

Combined with other bio-chemicals that are mostly produced during sleep, melatonin helps your skin stay young, soft and supple.

When you go to bed with clothes on, you literally encourage your entire body to age. Read more anti-aging tips here!

9. More substantive ejaculate

For guys, sleeping in the buff empowers your entire sex organ system to remain at a healthy temperature. In turn, this helps to promote a better functioning woody wood pecker – and shooter!

If it’s been awhile since you’ve experienced nocturnal penile tumescence (aka morning wood), you should toss off your boxers and enjoy the amazing sensation of soft, cool sheets.

10. Less anxiety

If you feel anxious during the day, there’s no better way to ameliorate the jitters than by jumping into bed naked. That may sound silly but it’s really not.

When you go to bed unclothed, you provide your body a natural, restorative environment. In turn, you’ll get a more meaningful night’s sleep.
