The more couples live together, the younger they become

Moderate marital life may have a certain positive effect on delaying aging, but excessive frequency may be counterproductive. Its mechanism mainly involves five aspects: hormone regulation, stress relief, immune enhancement, skin condition improvement and mental health.

1. Hormone regulation:

Regular sex can promote the secretion of "happy hormones" such as endorphins and oxytocin, while maintaining stable levels of estrogen and testosterone. These hormones help maintain bone density, muscle mass and metabolic rate, but excessive frequency may lead to hormone disorders, which in turn accelerates fatigue and cell oxidation.

2. Stress relief:

Cortisol levels drop by more than 40% during orgasm, and a sustained low-pressure state can reduce free radical damage to telomeres. It is recommended to do it 1-2 times a week. Excessive frequency may aggravate oxidative stress due to insufficient recovery of the body.

3. Immune enhancement:

Moderate sexual activity can increase immunoglobulin A levels by 20%, but more than three times a week may reduce local immunity due to repeated mucosal congestion. Clinical observation shows that those who have sex 8-12 times a month have the lowest upper respiratory tract infection rate.

4. Skin improvement:

During sexual excitement, skin blood flow increases by 200% and promotes collagen synthesis. However, frequent sex may lead to disorders of melatonin secretion rhythm, which may affect skin repair function. It is recommended to avoid doing it late at night.

5. Psychological rejuvenation:

The sense of belonging generated by close contact can reduce the perception of mental age, but excessive pursuit of frequency may translate into performance pressure. Research has found that couples who maintain an emotional connection have a subjective sense of youth that is, on average, 5-7 years younger than their actual age.

It is recommended that people aged 30-40 years old maintain sexual intercourse 2-3 times a week, along with aerobic exercise and a Mediterranean diet. People over 40 years old can appropriately reduce the frequency and increase the time of foreplay to improve the quality. Avoid doing it forcefully after fatigue or drinking, and replenish water and high-quality protein in time after sexual activity. If you have overdraft symptoms such as persistent waist and knee soreness, lack of concentration, etc., you need to wait 2-3 days for recovery. In winter, the frequency can be appropriately reduced, and in summer, pay attention to keeping the air-conditioned room warm. If there is no improvement for a long time, it is recommended to test six hormones and antioxidant indicators.
