Fat People are More Afraid of High Temperatures

1. Older heart weakness
When the temperature or body temperature is too high, the body needs to transport more blood to the body surface to help dissipate heat, but as we get older, the heart is no longer as strong as it used to be, and the blood vessels are not as healthy as when they were young. It is easy to be blocked, and the speed of adjusting to temperature changes is not as fast as when you are young. Therefore, the elderly are more likely to feel hot, especially those over 65.

2. Drug side effects
The side effects of some drugs may cause the body to produce excess heat and sweat, such as: zinc-containing drugs or nutritional supplements, certain antidepressants, hormonal drugs, antibiotics, painkillers, heart disease or high blood pressure drugs.

3. Caffeine or alcohol
It’s reasonable to drink hot soup and hot food to make your body warm, but what about a cup of iced coffee? All beverages containing caffeine, alcohol and other ingredients will increase the body’s metabolic rate and heart rate, thereby increasing body temperature and perspiration, while spicy foods contain capsaicin, which will increase body temperature and perspiration.

4. Too much coffee
In order to improve work efficiency, a refreshing cup of coffee in the morning is indispensable, but did you know that coffee can also increase body temperature? Caffeine is a stimulant, which can increase blood pressure and heart rate and make people feel hotter. The Ministry of Health and Welfare stated: “According to the evaluation of the European Commission of Food Science Experts, the recommended daily intake of caffeine is less than 300 mg, which will not affect health. .” Therefore, it is recommended not to consume too much coffee, otherwise besides being hotter, there may be side effects such as anxiety.

5. The body is still adapting to temperature changes
For an average healthy adult, it takes about 2 weeks to adjust to the temperature of a new environment, and it will take longer for those who are older or in poor health. After the acclimatization period, you will not feel as hot as before. Even if your body is active, the body temperature and the ability to maintain a constant body water will be better than at the beginning. If you stay in an air-conditioned room for a long time, it is recommended that the temperature not be lower than the outdoor temperature by more than 5°C, so that it can better adapt to the outdoor temperature.

6. Fever and high body temperature
The best temperature to keep the human body functioning normally is about 37 degrees Celsius. If the body temperature is too high, it is possible to have a fever. Feeling of heat and sweating is a common process for fever. However, fever is a natural way for the body to fight germs and diseases. If you continue to feel unwell, or if you have a high fever exceeding 39.5°C, it is recommended to seek medical assistance.

7. Exercise generates heat
The operation of the body consumes heat and generates heat energy, and exercise generates more heat energy. In order to cool down, the body will send higher temperature blood to the surface of the skin and lower body temperature through perspiration.

8. The weather is too hot and humid
In Taiwan’s hot and humid environment, especially during the rainy season, not only does it have high temperatures, but it also rains all the time. The higher the humidity in the air, the more difficult it is for the sweat on the skin to evaporate, which makes it difficult to dissipate heat and makes people feel hotter. The “body temperature” we often hear.

9. Fat people are more afraid of heat
Is it true that being overweight is more afraid of heat? Studies have shown that obesity is closely related to body temperature, especially in men and post-menopausal women. Different studies have also pointed out that the core body temperature of obese people is lower, so it is quite reasonable for obese people to feel hotter at the same temperature. Another potential reason is that people with heavier weight have higher basal metabolic rate (BMR) and higher body temperature. The skin is the main organ for heat dissipation. Compared with people of normal weight, the skin accounts for a smaller proportion of the total body weight, so the ability to dissipate heat is relatively poor.

Feeling hot and starting to sweat is actually the body’s mechanism for regulating body temperature, which is used to discharge excess heat in the body. However, everyone’s physical condition, heat tolerance or perspiration ability is different. Some people still jog for several kilometers. The face is not red or breathless, and some people are sweaty after walking a few steps, so you still have to rely on personal feelings. If the heat is uncomfortable, you should go to the shade as soon as possible to replenish water to avoid heatstroke or dehydration. Seek medical attention if the condition does not improve.
