From a scientific perspective, physiological needs include hunger, thirst, sleep, sexual desire, etc. These needs drive human behavior and decision-making. The following is the hot content related to physiological needs among the hot topics on the Internet in the past 10 days, presented through structured data.
1. Analysis of popular physiological needs topics

| Topic Category | Hot search keywords | Discussion popularity (index) | Typical events |

2. Scientific explanation of physiological needs
The core of physiological needs is to maintain life and continue genes. The following are the biological mechanisms of major physiological needs:
| Physiological needs | trigger mechanism | related hormones | evolutionary significance |
|---|---|---|---|
| hungry | drop in blood sugar levels | Ghrelin, insulin | Ensure energy supply |
| thirsty | Increased blood osmolality | antidiuretic hormone | Maintain body fluid balance |
| Sexual desire | changes in sex hormone levels | Testosterone, estrogen | Promote gene transfer |
| sleep | circadian rhythm regulation | Melatonin, adenosine | Repair body functions |
3. Alienation of physiological needs in modern society
With the development of society, the manifestations of physiological needs have gradually become more complicated:
1.Alienation of dietary needs: From satisfying hunger to socializing, the average daily order volume of the takeout economy has exceeded 80 million, but the obesity rate has simultaneously increased to 12%.

4. Suggestions on health management of physiological needs
| Requirement type | health standards | management advice |
|---|---|---|

| sports | 150 minutes/week | Combined aerobic and strength training |
5. Cutting-edge research and future prospects
The latest research shows:
1. The relationship between intestinal flora and appetite regulation has become a hot topic, and specific strains may help control bulimia.
2. Optogenetic technology is expected to accurately regulate sleep cycles, and animal experiments have achieved artificial induction of deep sleep.
3. A breakthrough was made in the research on the neural mechanism of sexual desire, and the control effect of specific neuron clusters in the hypothalamus was discovered.
Physiological needs are both the shackles of life and the gift of evolution. Correctly understanding and scientifically managing these needs is the only way for humans to move towards a healthier life. Contemporary society needs to establish a more complete public health system to help people regain physiological balance in an era of material abundance.
