Sleep is one lifestyle factor that is often overlooked in fertility. Did you know that in the UK alone, 40 % of adults suffer with sleep issues? Nowadays, due to our busy lifestyle, sleep is seen more as a luxury than a necessity. We tend to get home later from work, watch TV or scroll on social media late instead of preciously taking care of our sleep. We are far from the 7 to 9 hours sleep required for adults.
In this blog, we will discuss how sleep affects fertility and provide 5 expert tips to improve your sleep for better reproductive outcomes.

The Science Behind Sleep and Fertility
Sleep is crucial for the production and regulation of hormones like oestrogen, testosterone, and follicle-stimulating hormone (FSH). For example, studies suggest that individuals who get less than seven hours of quality sleep are 60% more likely to experience irregular menstrual cycles, which can severely impair ovulation and sperm production.
A few more facts on how sleep impacts fertility for women and men:
Our circadian rhythm regulates our reproductive hormone production so nighttime light exposure disrupts our menstrual cycles.
Poor sleep is linked to irregular periods and menstrual pain.
Poor sleep quality can spike stress hormones like cortisol, further disrupting reproductive processes.
Women who maintain a consistent sleep routine experience smoother menstrual cycles, leading to more predictable ovulation.
For men, studies show that those who consistently get inadequate sleep may see testosterone levels drop by up to 30%, leading to lower sperm counts and impaired fertility.
Tips to Improve Sleep for Better Fertility
Improving sleep quality can enhance fertility for both men and women. Here are some effective strategies:
Try to get some sunlight first thing in the morning
This will help increase you cortisol levels by over 50% giving you energy but also helping you reset your internal clock and eventually sleeping better at night.
Minimise your blue light exposure before bed
Blue light from screens can interfere with melatonin production, the sleep hormone. To counter this, avoid screens at least one hour before bedtime or use some blue light blocking glasses.
Sleep in complete darkness
It will help you get a better night sleep but also support your melatonin production. Melatonin has been shown to improve egg quality and support progesterone production in the luteal phase (the phase after ovulation).
Limit caffeine and alcohol
Did you know that consuming caffeine 6 hours before bed can double the time it takes to fall asleep? Try to choose herbal teas instead for better sleep. Alcohol in the evening also disrupts sleep: even though some people drink alcohol in the evening to sleep better, in reality, alcohol before bed can lead to frequent wakings and overall low-quality sleep.
Create a restful nighttime routine
It does not have to be complicated or time-consuming: a nighttime routine can be as simple as taking a hot shower, shutting off your devices and reading a few minutes before switching off the lights. Try and be in bed by 10pm.
Understanding the connection between sleep and fertility is essential. Prioritising high-quality sleep can lead to hormonal balance and improved fertility health for both women and men. By implementing these expert tips, you can enhance not just your sleep quality but also your overall reproductive health.
