Sexual intercourse has a lot of benefits outside of the reproductive method, such as reducing stress, releasing several hormones with a beneficial effect into the blood, and others. But there are situations where sexual activity is contraindicated, such as people with cardiovascular problems (high blood pressure, heart problems, etc.) and involves certain risks. If you have had a myocardial infarction, it is recommended to rest completely (in serious situations) or for a certain period (at least 6 weeks, in slightly milder cases, to give the heart time to recover).
In other situations, sex and orgasm can trigger serious migraines (severe headaches).
Sexual intercourse and heart disease
Even if it doesn't last too long (ranging from a few minutes to half an hour if you insist on a prolonged and quality foreplay), sexual intercourse increases the heart rate to over 100 beats per minute and blood pressure by 2-3 mm. You know very well that a man needs good circulation to get a quality erection because the blood fills the corpus callosum of the penis producing the firmness of the sexual organ, and the woman needs well-vascularized sexual organs to feel more intense orgasm is put into circulation).
Prolonged stress on the circulatory system (caused by repeated or prolonged sexual intercourse) or more aggressive sexual intercourse can aggravate certain cardiovascular diseases. And when the patient has respiratory failure, severe decompensation or has suffered one or more heart attacks, sexual intercourse presents a number of risks that you should take into account.
If during sexual intercourse there are specific symptoms such as pain in the heart or chest, weakness, hypotension, pale face or gray skin, wet and cold skin, then it is urgent to stop any activity, rest and call 112 and services emergency medical services.
Specialists believe that the sexual intercourse of men with heart problems should not exceed 20 minutes when the patient's condition is good or excellent and less than 10 minutes when the disease manifests itself. In addition, the patient should not consume aphrodisiacs or stimulants without a doctor's recommendation, and when administering nitroglycerin should be avoided strong stimulants.
Sexual intercourse and severe migraines
Migraine may initially feel like a dull headache, but it gets worse as the arousal increases. In this situation the headache is caused by the contraction of the muscles of the head and neck during intercourse. Another manifestation of headache, somewhat more common (it is estimated that about 1% of people suffer from this at some point in their lives), is a sudden and severe headache just before orgasm. It can be caused by a stroke or bleeding inside the brain.
Sexual activity, especially orgasm, can trigger the onset of migraine, which is initially felt as a dull headache that worsens as arousal increases. Headache is, in this case, the effect of contracting the muscles of the head and neck during sexual intercourse.
Sexual intercourse during pregnancy
It is contraindicated only in some cases: when there is undiagnosed vaginal bleeding or amniotic fluid leakage from inside the placenta, or increased risk of premature birth or completely closed cervical orifice, but also placenta in risky positions (may rupture).
However, there are many myths about sex during pregnancy, but one thing is clear: as long as you do not try unusual positions the fetus is not affected by the penetration of the penis because it is protected by the uterus, placenta and amniotic fluid.
It is good to know that in the first semester of pregnancy hormonal changes and nausea can decrease sexual appetite, but in the second semester the increase in vascularity in the genital area due to pregnancy increases sexual appetite. Even if orgasm causes a series of uterine contractions, they have nothing to do with labor and do not involve any risk of premature birth.
