Adolescents who dont get enough sleep may be jeopardizing their athletic overall performance.

‘This situation is most problematic for teams on the east coastline that travel west, as student sports athletes may return with a substantial sleep-phase delay that’s difficult to correct,’ Carskadon says. Lack of sleep doesn’t simply affect athletics in teens. Studies repeatedly show that reaction time, vigilance, learning and alertness are impaired by insufficient sleep; so students with brief nights and irregular sleep patterns perform badly in college and in other aspects of their life and also have a tendency for a depressed feeling. ‘Circadian and changes in lifestyle conspire to place rest of adolescents at a markedly delayed time relative to younger children and to adults,’ says Carskadon.Bednarek, M.D., M.P.H., Mitchell D.

For the Post-Aspiration IUD Randomization Study Trial Group: Immediate versus Delayed IUD Insertion after Uterine Aspiration More than half of most unintended pregnancies in the usa occur due to inconsistent or discontinued use of contraceptives.1 Intrauterine devices provide safe, highly effective, long-term contraception, but they are underused.2 Because IUDs usually do not require energetic use, once they possess been inserted, and also have a very low failure rate, their increased use has the potential to substantially reduce unintended pregnancies.3 Immediate initiation of any contraceptive method after an abortion has been associated with a reduced threat of repeat abortion,4 with immediate usage of an IUD the most efficient method for reducing this risk.4,5 IUD placement soon after uterine aspiration could get rid of the need for an additional visit and assure effective contraception by the time ovulation resumes, as early as 2 to 3 3 weeks after the procedure.6 Although many women would like immediate IUD insertion,7 such insertions have been limited by concerns about increased prices of expulsion, uterine perforation, and infection and by concern about increased cost.
