Sleep Cycle for Women: Staying up late and not getting enough sleep can affect women's hormones, ovulation, and fertility. Learn why it's important to sleep by 11 p.m.

Benefits of sleeping before 11 pm
Sleep Cycle For Women: In today's fast-paced life, women compromise the most on their sleep while managing home, job and family. Staying up late at night on mobile, work or household chores and then getting up early in the morning. This cycle continues everyday, but do you know that this incomplete sleep not only causes fatigue but can also harm your periods, the level of stress-causing hormones in your body, the functioning of insulin in the body and even your ability to become a mother? Doctors say that sleeping before 11 pm is very important for women's health and ignoring it gradually creates many problems in the body.
Direct relationship between sleep and hormones
Our body works like a clock, and sleep is the key to that clock. According to experts, women's hormones and their sleep are closely linked. The total number of hours you sleep at night is important, but the time at which you sleep is equally important. Furthermore, the same part of the brain that controls sleep and wakefulness hormones also triggers ovulation, the process of egg production, in women. The hormone LH, or Luteinizing Hormone, which triggers ovulation, is produced during deep sleep. If sleep is repeatedly interrupted, LH production decreases, which can lead to irregular periods or missed ovulation.
You will be shocked to know what can happen due to a lack of sleep.
When women don't sleep well or sleep at inappropriate times, it directly impacts the hormones involved in their ability to conceive. This means that the balance of estrogen, progesterone, melatonin, cortisol, LH, and FSH is disrupted. Melatonin, of these hormones, maintains the quality and safety of a woman's eggs, but lack of sleep can lead to its production being inadequate.
On the other hand, not getting enough sleep significantly increases cortisol levels in the body, which is primarily known as the stress hormone. Elevated cortisol levels disrupt the communication between the brain and the ovaries, inhibiting the release of LH and FSH hormones. These two hormones are responsible for the development of eggs in the ovaries and their release at the right time. Simply put, lack of sleep increases stress hormones and decreases egg-protecting hormones, which can lead to problems conceiving or achieving pregnancy in the future.
How much sleep should women get?
According to doctors, 7 to 8 hours of sleep is considered optimal for women's reproductive health. A study by the American Society of Reproductive Medicine found that women who slept this many hours were significantly more likely to conceive than those who slept less than 7 hours or more than 9 hours. Therefore, doctors recommend going to bed by 11 pm.
