Why You Should Care About the Link Between Sleep & Testosterone

October 13, 2020


 The important link between sleep & testosterone production

Let's be honest, this whole getting old business isn't always fun and games. Your crowning glory goes grey (if it stays put that is) and your body starts to give in to the rigours of life. This includes a reduction in the production of testosterone, a hormone that plays an important role in the vitality and longevity of both men and women. 

By the time we turn the dreaded three-oh, our testosterone levels start to dip by at least 1% every year on average. This carries on until our 40s and 50s, when both men and women will start to notice the signs of so-called 'low T', which normally announces itself in the form of decreased libido and a general lack of verve. 

Here’s the kicker - the amount of healthy, natural sleep you’re getting is linked to your testosterone levels.  

The longer you're awake, the lower your testosterone levels dip. It increases again while you sleep, reaching its peak while your body enjoys that really deep REM sleep later in the sleep cycle. This is when your body and mind really get the true replenishment it needs to keep going on a daily basis. 

You can't cheat your body on this. A recent study showed that if you clock less than 6 hours of sleep for more than 7 days running, you can expect a decrease of up to 15% in terms of testosterone production because your body is not in REM long enough to replenish its stores. 

So, what's the big deal? Here's what happens when your body is running low on testosterone: 

  • Your libido dips - no good for anyone in a relationship. 

  • You burn fat at a snail's pace - no good for anyone trying to stay in shape. 

  • Muscle growth slows way down - no good if you're trying to stay fit and nimble in your later years. 

  • Brain health suffers - no good if you want to keep your memory in tip-top shape. 

It’s important to note that the symptoms of low T are not just noticeable in men. Women who lack sufficient levels of this important hormone will also feel lethargic, have a tough time maintaining muscle mass and notice a decline in their sex drive. 

Now you know. Take care to get sufficient rest and reap the benefits in terms of more balanced hormones. Check back soon for more expert insight on all things sleep-related.
