According to Dr. Tra Anh Duy, MD, PhD, from the Men's Health Center, as shared on VnExpress, blue light from phone screens can inhibit melatonin – the hormone that helps the body fall asleep naturally. When sleeping late and not sleeping soundly, the body experiences prolonged fatigue, directly affecting testosterone levels in men and hormonal balance in women.
Numerous studies show that simply sleeping less than 5 hours a night for about a week can significantly reduce testosterone levels in men. This hormone plays a crucial role in libido, erectile function, stamina, and mood. When this hormone declines, men may feel indifferent about sex, while women often experience fatigue and a loss of interest in intimacy.
It's worth noting that the impact of phone use isn't limited to just sleep deprivation.

When a husband and wife lie next to each other but no longer connect.
Many couples today have a familiar bedtime routine: each person holds a phone, one watching TikTok, the other browsing Facebook, the other answering work-related questions, with almost no conversation between them. Hugs, caresses, or a few minutes of heartfelt conversation before sleep are gradually disappearing.
Psychologists call this phenomenon "phubbing"—ignoring the person next to you to focus on your phone. In the long run, this creates feelings of neglect in a marriage.
Sexual desire doesn't just appear spontaneously like flipping a switch. It's nurtured by small interactions: eye contact, touch, questions, the feeling of being cared for and listened to. When all emotional energy is absorbed by the phone screen, the intimacy between two people gradually dwindles.
Many people don't realize that lying next to each other while everyone is engrossed in their phones makes the brain accustomed to quick, short, and constant stimuli from videos , messages, notifications, or "likes." Over time, the brain becomes desensitized to the slow, deep emotions of real life, including marital intimacy.
Having a phone in the bedroom can also cause many health problems.
Besides reducing libido, using your phone before bed also leads to a host of other problems such as:
Sleep disorders, difficulty falling asleep, and shallow sleep; increased stress and anxiety; reduced concentration and daytime energy; increased risk of obesity due to staying up late and eating at night; worsening of erectile dysfunction in men; and increased irritability and conflict between spouses due to lack of communication.
Especially for those who have reached middle age, work and life pressures already cause physical fatigue. If they stay up until 1-2 AM every night scrolling through their phones, their physiological functions can easily decline.
Many men mistakenly believe they have "sexual dysfunction" and secretly seek enhancement drugs, but in reality, the cause lies in a long-term unhealthy lifestyle.
How can we prevent phones from ruining our marriage?
Experts suggest that complete phone withdrawal isn't necessary, but it's important to set clear boundaries, especially in the evenings.
Some simple but very effective habits include:
Stop using your phone at least 30-60 minutes before going to bed.
Don't bring your laptop or phone to bed unless absolutely necessary.
Turn off social media notifications at night.
Spend time talking, giving each other a massage, or cuddling before bed.
Go to bed on time and prioritize getting 7-8 hours of sleep.
Limit watching short videos that provide continuous brain stimulation.
Many couples have noticed a significant change after adopting "device-free time" in the evenings. They sleep better, experience less stress, and feel closer to their partners.
In marriage, sometimes what cools down the relationship isn't a third party, but the phone screen that's always lit up between the two of you every night.
