If you want hard-rock boners, you need to limit your sugar intake. Sugar affects your body’s testosterone production, making it tougher for you to get it up.
2. INADEQUATE SLEEP:
I understand you have to work real hard which means lesser sleep but if you desire to maintain your boners, then you need to get adequate sleep. Sleep is essential for testosterone production.
You probably didn’t want this to be in this list but I am really sorry to disappoint you. Taking too much alcohol lowers your testosterone levels. So easy with the booze.
4. RUNNING TOO MUCH:
Running 40 or more miles a week can drop your testosterone level by 17% according to a University of British Columbia research.
5. SPENDING TOO MUCH TIME INDOORS:
Spending too much time indoors affects your boners due to lack of vitamin D you fail to receive from the sun and this vitamin is important in the production of testosterone.
Too much of everything they say is bad and that also includes soy which according to a Harvard Medical School research if consumed too much over an extended period of time could affect your boners.
