Can Old Scars Hurt In Hot Weather?

I asked Google AI, the question in the title of this post, and received this answer.

Yes, old scars can absolutely hurt or feel irritated in hot weather. Because scar tissue is different from normal skin, it doesn’t have the same elasticity, sweat glands, or ability to regulate temperature, making it highly sensitive to environmental changes.

Consult the NHS Scars Guide for general wound advice, or seek help from your local GP if you notice sudden or severe inflammation.
Several specific factors cause scars to flare up in the heat:
Nerve Sensitivity: During an injury’s healing process, nerve endings can over-proliferate or reconnect abnormally.
Changes in temperature and barometric pressure can cause these sensitive nerves to fire, leading to aching, throbbing, or tingling.
Sweat & Irritation: Scar tissue lacks normal pores and sweat glands. Sweat can get trapped and pool around the rigid, raised, or indented tissue, resulting in severe itching and localized rashes.
Skin Adhesions: The tissue beneath the scar can bind to underlying muscles or tendons. In the heat, skin and underlying tissues expand, which can tug on these adhesions and cause a pulling, burning, or aching sensation.
UV Vulnerability: Scar tissue lacks the protective melanin of normal skin. Even years later, the area is prone to burning faster and becoming hyper-pigmented,

Wrightbus To Supply 20 Electroliner Buses To Hong Kong

The title of this post, is the same as that of this article on bus-news.

These are the first two paragraphs, which give more details.

Wrightbus has received a major order for a set of 20 of its 6×2 StreetDeck Electroliner double-deck buses.

The vehicles have been ordered by Hong Kong’s Citybus, marking the first global order for the new triple-axle vehicles.

I feel very strongly after a very terrible Bank Holiday weekend, that these are the buses we need on the 141 route in London, that I use most days.

Currently, we have BYD’s Chinese Junks and the batteries are too small.

  • On Saturday, I had a doctor’s appointment and had to wait 45 minutes for a bus.
  • On Sunday, I had to take a taxi.
  • On Monday, it was a twenty minute wait and in the end I took a 76, which are Routemasters and walked.
  • On Tuesday, I was rescued by an elderly Wrightbus, after twenty minutes wait.

The article on bus-news says this about the three-axle buses.

Measuring 12-metres in length; the StreetDeck Electroliners are capable of carrying up to 82 seated passengers (130 total), and possess an operating range of up to 300km.

That would do us fine in De Beauvoir Town, so we could travel reliably to London Bridge and Palmers Green.

As an engineer, I suspect the longer buses with an extra axle can carry a larger battery. I also suspect that BYD’s batteries don’t perform well in hot weather.

Instead, we get Chinese Junks and Hong Kong will be getting quality British buses built in Malaysia.
