What time should men sleep for the healthiest sperm?
Scientists have tracked the sleep of 981 healthy men. They asked the volunteers to go to bed at fixed hours: from 8-10pm, 10pm to midnight, after midnight and set an alarm to experience sleep that lasted 6 hours or less; 7 - 8 - 9 hours or longer.
Researchers regularly sample semen from participants to test the quality, shape, movement, and speed of sperm.
Test results showed that people who go to bed after midnight have a strong decrease in sperm count, sperm will die earlier. In the 6-hour or less sleep group, both the amount and quality of sperm were worse than the group sleeping for more than 9 hours.
Going to bed in the evening from 8-10pm is the boys will have the best sperms, the highest movement speed. This means that sperm will easily go deeper and have a higher chance of conceiving with eggs.
Experts also noted that boys who sleep late, do not rest, relax will make sperm decrease in both quantity and quality by increasing antibodies against sperm, a protein created by the immune system. Can destroy sperms.
In February, scientists from Boston University, USA, also concluded that sleep too short or too long affects testosterone - an important hormone that stimulates sperm production in men.
In short, men need to sleep about 6 hours / night and sleep time from 8-10 hours to get the best healthy news.
