Good sex not only makes people happy physically and mentally, but also brings many unexpected benefits. Recently, American sexologist Barbara Pease pointed out in her new book "Men Need Sex, Women Need Love" that sex is a magical "panacea" that can help people resist various diseases and strengthen their bodies. Here are the top 10 reasons why sex is good medicine.

1. Prevent allergies. Sex is a natural antihistamine that can help reduce nasal congestion and hay fever, and can also effectively reduce the incidence of asthma.

2. Treat dermatitis. Sweat during sex can clean pores and increase skin surface temperature, helping to quickly recover from skin diseases such as dermatitis, rashes and acne.

3. Eliminate depression. During sex, a large amount of endorphins are produced in the brain, which can make people feel pleasure and happiness. Research from the University of California in the United States shows that after an orgasm, 85% of patients with mild depression will have reduced symptoms. Therefore, sex is better than taking pills when you are feeling depressed.

4. Effective weight loss. Sex can help people enjoy pleasure while eliminating fat, and the effect is even better than weight-loss drugs. Different sexual positions can stretch and exercise every muscle in the body, and the exercise effect is comparable to swimming and running.

5. Helps you sleep well. For men, a strong 5-10 second orgasm is equivalent to taking 2-3 mg of diazepam, which can help them fall asleep quickly. For women, having sex 10 times can help reduce the frequency of insomnia.

6. Relieve headaches. Sex can effectively relieve headache symptoms by releasing tension.

7. Strong bones. Regular sex can increase estrogen secretion, and estrogen has the effect of maintaining bone health and reducing the risk of osteoarthritis.

8. Prevent tooth decay. The large amount of saliva secreted during kissing can clean teeth and reduce the acidic substances that cause tooth decay.

9. Protect the heart. Regular sex can halve the risk of heart disease and stroke, but the elderly and patients with heart disease should avoid intense sex.

10. Love elixir. Sex makes people "love more and more" and enhance mutual intimacy.
