I just stumbled upon one of the biggest reasons yet for why you should never ignore insomnia.
Researchers at the University of Southern Denmark examined almost 1,000 men. The men gave sperm samples and were also asked about their sleep.
The study found that those who went to bed late at night, frequently woke during the night, or had trouble falling asleep had a sperm count that was 25% lower compared to those who slept normally.
Researchers also found that the testicles of those with insomnia symptoms were significantly smaller than those who slept well.
The researchers have no idea why there appears to be a link between sleep deprivation and lower sperm counts and smaller testicles, and they're keen to point out that there is no proof that insomnia is to blame (or vice-versa).
Researchers also suggest that testosterone and sleep may be far more closely linked than we ever thought.
