I'm a man in my mid-50s, around the same generation as Mr. Sakamoto, and lately, if I stay up all night, I catch a cold, and when I do catch one, it takes longer to recover, making me feel my physical strength is declining.

Mr. Sakamoto is incredibly active, juggling composition, recording, live performances, lectures, discussions, and interviews, but...
How do you manage to stay so energetic? And when you catch a cold, what's the best way to recover quickly?
If you have any good advice, please share it.

Catching a Cold Makes You Healthier

You should read the book "The Efficacy of Colds" by Haruchika Noguchi, who founded Noguchi Seitai.
It states that catching a cold actually makes you healthier, so it's better not to force a cure. When I read this, it was a revelation.

The human body tries to expel foreign substances. A fever is meant to kill viruses, and vomiting, diarrhea, and rashes operate on the same principle.
So, we should actually support these bodily responses. If you have a fever from a cold, you should warm your body further with things like foot baths or ginger tea to encourage sweating. Simply suppressing the fever, for example, by trying to force it down, is not beneficial.

The Cause of Feeling Cold

As I've gotten older, I've also found myself feeling colder.
Until just seven or eight years ago, I never felt this way, but now, past the age of 50, I feel cold even on days that aren't particularly chilly.
The reason for this coldness is excess moisture within the body. When the circulation of fluids, carried by blood and lymph, becomes sluggish, unnecessary moisture accumulates in various parts of the body, leading to a feeling of cold.

Aging is a "slow death." Organic matter gradually transforms into inorganic matter over time, and the body naturally deteriorates.
This is unavoidable; it's simply how things are.
Incidentally, I've recently taken to wearing long johns. I recommend silk long johns made in New Zealand. Thin silk ones aren't bulky and look sleek. They regulate both heat and cold, providing a natural feel, and help alleviate body coldness.
Regarding "health," let's state it this way:

It's Unavoidable for the Body to Deteriorate with Age!
Catch a Cold!
For Coldness, Silk Long Johns!
