Care to guess the most effective way is to increase testosterone? You would likely guess that it has to be something which requires a large amount of effort or expense, right? Effectively, actually all you need to accomplish is sleep, sleep, rest. While you sleep - that's assuming you've extensive, quality sleep - the body ramps of yours up testosterone production. Your testosterone levels are at a daily peak at aproximatelly 8 a.m. and after that decreases to a regular low at about 8 PM.  
You need to have quality sleep to bring the testosterone of yours back up to optimal levels. While you are sleeping, yourself pretty much turns on its Testosterone Engine and, such as an IV drip, pours extra testosterone in your system in rhythmic cycles based on basic sleeping stages. The greater uninterrupted rest, the more testosterone - it's that simple.  
The notion that more sleep boosts testosterone is simply common sense for us males. Every guy knows that after a very good night's rest you wake up feeling good. Libido, strength, morning erections and general attitude - all symptoms of high testosterone - are all significantly enhanced after sleeping well and long. And what we understand naturally has been verified by many studies. A recent study of older males, ages sixty four to 74, found that sleep was largest impartial predictor of morning free and total testosterone levels.  
  
One more example is a 1992 research of sixty seven good males between the ages of forty five and seventy five realized the following were just about all correlated to an increase in testosterone levels:  
1. Sleep efficiency  
2. Number of REM episodes  
3. Duration of REM episodes  
4. Decreased length of wake time (from a disturbance such as apnea)  
This particular study did not list by just how much average testosterone changed for the study participants: the researchers just reported "statistical significance". However, from what I've noticed, statistical significance translates to at least twenty % with regards to testosterone levels. Remember that twenty % is seventy or maybe much more ng/dl for a reduced T guy and will surely make a positive change.  
Yet another more recent analysis of shift workers found that "high testosterone levels were associated to satisfaction ] and [ fewer sleepiness difficulties. Additionally, increased testosterone levels were also connected with sufficiency of sleep as well as to being well rested after day slumber and to much less disturbed sleep at night before morning shifts." Again, no average testosterone levels have been given but statistical significance could reasonably be assumed to be 20 % or even more.  
This is Explore further; finance.yahoo.com, established by several of the scientific studies which have shown the reverse: testosterone is slashed with disturbed or low quality sleep. One study of 10 nutritious, non-smoking, trim 20 year olds demonstrated that fragmented sleep resulted in ZERO nighttime T increases. During normal sleep these same ten young men had normal nighttime testosterone increases of twenty to 30 % or maybe more. But with disturbed sleep their T flat lined at night. Quite simply, their T was frozen at daytime values. Naturally, this is terrible enough for an individual in their twenties, though it's particularly bad for someone in middle age. A similar result was found in a study of 45 men with serious apnea, a rather standard sleep disorder where breathing is perfectly blocked. When these men commenced successfully utilizing CPAP machines, to correct their apnea, their testosterone levels rose on average twenty %.
