Many men claim to get by on 4-5 hours of sleep a day but robbing the body of its required sleep has a number of side effects. The human body requires a minimum of 8 hours of sleep a day. There are two main reasons men don't get enough sleep: intentionally staying awake late at night and sleep disorders such as insomnia, sleep apnea etc. Here's how depriving your body of sleep can harm your sexual health.
Less testosterone
The male body produces testosterone while he sleeps. When the body does not get adequate sleep and rest, it produces less testosterone. As the insomnia continues, this situation worsens. This leads to a low sex drive and poor libido.
Low self esteem
Testosterone also influences the way the body stores fat and hence less testosterone can also lead to gynecomastia. This is condition where male bodies develop breasts as a result of an increase in body fat. Lowered testosterone levels in a male body also lead to reduced muscle strength and hence an overall lower sense of well being.
Erectile dysfunction
Inadequate sleep can result in obstructive sleep apnea. This is linked to the lowered levels of testosterone in the body as patients with sleep apnea do not reach the stage of REM sleep when testosterone is produced. Thus, sleep apnea can lead to erectile dysfunction where a man is unable to get or maintain an erection while having sex.
Low sperm count
Testosterone plays an important role in sperm production. The relation between the two is simple: the higher the testosterone levels; the more the body produces sperm. Thus if you do not get adequate sleep, your sperm count can be affected leading to infertility.
Sexual misunderstanding
Sleep deprivation can affect your decision making and understanding of the other person's intentions. Thus if you haven't slept properly, you are more likely to make uncalled for sexual advances and misunderstand your partner's sexual expectations.
Accelerates aging
The body sheds dead cells and grows new cells while it sleeps. Thus if the body is deprived of adequate sleep, the gaining process is accelerated. Not only does this bring on an early onset of wrinkles but it also lowers your sexual drive. Lowered testosterone may also lead to early balding.
Fatigue
If the body doesn't get its required rest, you start the day feeling tired instead of refreshed. As the day goes on, this tiredness increases and is accompanied by irritability and aggression. When you're in such a bad moon and constantly tired the chances of wanting to be physically intimate with another person decrease. If you wish to discuss about any specific problem, you can consult a Sexologist.
