Sci­en­tists from the Uni­ver­si­ty of South­ern Den­mark have found a rela­tion­ship between men’s sleep prob­lems and their abil­i­ty to con­ceive. The exper­i­ment involved 1000 men, whose aver­age age was 20 years. They donat­ed sem­i­nal flu­id and filled out a spe­cial ques­tion­naire with ques­tions about their sleep. In par­tic­u­lar, they had to be told how quick­ly they fall asleep, how often they wake up in the mid­dle of the night, and how long their unin­ter­rupt­ed sleep is.

The data obtained allowed sci­en­tists to con­clude that in men who had sleep dis­tur­bances, the num­ber of sper­ma­to­zoa decreased by 25%. In addi­tion, their tes­ti­cles were small­er than aver­age. In addi­tion, sleep prob­lems affect the lev­el of the hor­mone testos­terone: the longer a man spends with­out sleep, the low­er the lev­el of the hor­mone.

Researchers at the Uni­ver­si­ty of Birm­ing­ham have shown that chron­ic sleep depri­va­tion con­tributes to the devel­op­ment of car­dio­vas­cu­lar dis­ease.

Experts empha­size that bad habits (alco­hol, smok­ing, overeat­ing) and stress often become the caus­es of poor sleep.
