I know that in this era when all young people are taking "soaking Chinese wolfberry in a thermos cup", there must be quite a few people who have never thought of developing good drinking habits. Seeing that the first batch of post-90s generation has been running brilliantly for three years, Antlers Net really can't sit still, so we have to jump out and kindly remind everyone that the flowers are similar year by year, and people are different year by year. Don't forget to add clothes when it's cold. People have to drink more water when they are old. ...

Of course, I didn't make this up. It was put forward by a group of diligent professional researchers at the University of Ottawa. This is real scientific advice.

You know, as you get older-I know you don't like it, but I'm not doing it for your own good? Our body will change greatly compared with before, and we may not be able to adjust the speed of perspiration, so it is very important to drink water even if we are not thirsty.

Not only that, we also need to drink more water to make up for the change of body temperature regulation. Because hydrating is the key to regulating body temperature, it helps to resist many other health problems.

When people reach a certain age, dehydration will not reduce the loss of heat as it did when they were young, nor will it lead to an increase in body temperature during exercise. On the surface, this seems to be a beneficial change, but it also means that when the elderly exercise, their bodies will not adjust the speed of sweat loss to prevent further dehydration. This will cause their hearts to bear more pressure than when they were young, and their heart rate will increase more obviously.

The decrease of the sensitivity of the elderly to the increase of blood osmotic pressure (salt concentration) can explain that the influence of dehydration on the hearing loss and body temperature regulation of the elderly is weakened during exercise and high temperature. Unlike young people, the temperature regulation of the elderly is not affected by the increase of salt in the blood. Lower thermoregulation efficiency will increase the risk of heatstroke and heart problems.

As we get older, the thirst center in our hypothalamus is no longer as active as before, so the brain doesn't always signal that we need to drink water. Therefore, the sooner we get into the good habit of drinking water, the better for our health. At least you can add a mechanism outside the brain to remind you of water intake.

You may have found that many elderly people seem to be less tolerant of cold. They can't stand the chill of the air conditioner, and they are always worried that you will be cold. Actually, they just feel cold. As we get older, we will also prefer warm temperatures, but often too warm environment will lead to excessive sweating, and you may be dehydrated before you realize it.

Once the elderly are dehydrated, one of the first damaged organs is the kidney, which will lead to acute renal failure and electrolyte imbalance, which may be fatal.

In addition, for some older men, there is a special problem, that is, they don't know or accept that their bodies have changed with age. They may think, I've been like this all my life, and there's nothing wrong with it. Why should I change now?

They don't think so, but forget "Lian Po is old, can she still eat?" This "wise saying" is still dreaming of old age, and it is really courageous. Many times, we should not overestimate our physical condition. Blind self-confidence will only harm ourselves.
