Schedule it 1-2 hours after a meal, both more comfortable and safer. I've noted this.

Marital life also requires choosing the right time; avoid scheduling during these three periods as much as possible.
Many healthy adults generally do not deliberately choose specific times for intimacy.
However, many doctors have found in clinical practice that discomfort in the body is often closely related to intimacy at inappropriate times.
Marital activity itself is considered moderate-intensity physical activity, during which heart rate and blood pressure can rise rapidly, and oxygen consumption increases.
If the body is not in the right condition, forcing oneself to engage can easily burden the body.
Do not engage in intimacy immediately after eating. After a meal, the stomach and intestines need to concentrate blood flow to digest food, and most of the blood supply will be directed to the abdominal cavity, with blood flow to the heart, muscles, and brain relatively reduced.
Engaging in intimacy at this time means the heart has to handle digestion and physical activity simultaneously, greatly increasing stress.
Data shows that the risk of cardiovascular incidents within an hour after eating is significantly higher than at other times, especially for older individuals or those with heart or blood pressure issues.
Under normal circumstances, it is best to wait 1 to 2 hours after eating, until digestion is nearly complete and blood flow has stabilized, for safer intimacy.
When feeling extremely tired, also exercise restraint.
When the body is exhausted, all functions are at a low level, the heart's capacity is weakened, and nerves become more sensitive and fragile.
Pushing through intimacy in this state not only easily leads to fatigue but also causes one to ignore uncomfortable signals from the body, which often become serious before being noticed.
It’s better to rest well and consider intimacy once your condition has recovered.
Avoid intimacy if you or your partner are sick.
During illness, the immune system is already fighting pathogens, and the whole body is in a state of depletion.
The rise in body temperature and blood pressure caused by intimacy can further burden the heart, especially during colds or when the body is weak, which can worsen the illness or even trigger heart-related problems.
During these three periods, the body is busy dealing with other matters and has no extra energy to handle additional physical exertion.
Understanding these is not about being overly cautious, but about knowing when to wait appropriately.
Taking care of each other's health is the key to long-term mutual appreciation.
