sickle cell disease and cold weather | Sickle Cell Disease News | Main graphic for column titled

Well, summer in the U.K. seemed to last all of 2 seconds. Now we are back to colder weather, shorter days, and higher heating bills.

As the colder seasons arrive, those of us with sickle cell disease need to be more intentional about looking after ourselves. The cold may expose us to more triggers, which can lead to a crisis or other sickle cell-related complications.

Avoiding infections

Unfortunately, COVID-19 is not yet a thing of the past, and colder weather tends to bring an increase in viral infections, such as the common cold and influenza. We must do what we can to reduce the risk of spreading or contracting an infection.

I plan to do this by ensuring I’m eating a balanced diet. I’ll include foods like citrus fruits and kale, which are high in vitamin C, to support the function of my immune system.

Although it’s no longer required in public spaces here, I still intend to wear a face mask. This will help reduce the chances of catching or spreading infections. I also intend to socially distance when I can, and avoid unnecessary contact with other people.

Staying warm

The cold is a known trigger of sickle cell crises. Our bodies naturally react to the cold by triggering mechanisms that preserve body heat in a process called thermoregulation. During this process, the blood vessels constrict, allowing less blood to flow through the skin. However, when this happens, it makes it even harder for a sickle cell patient’s blood to flow properly, and increases the chances of a crisis occurring. It’s important that we do what we can to stay warm.

I always say that I’d rather be too cold than too hot, and I stand by my statement, simply because I find it easier to warm myself up than to cool myself down. To stay warm, I make sure to wear warm clothing (99% of the clothes in my wardrobe are jumpers), I drink hot beverages, and I minimize my exposure to extremely cold weather. Unfortunately, that means no snowball fights in my near future.

If you have sickle cell, what changes do you make as the colder seasons approach? I would love to hear your tips and tricks in the comments below.

Hi. I live in Jamaica and though it's a tropical country we have lots of cold seasons. Unfortunately even when it's I tend to be cold at times and so I always ensure that I have a sweater with. As for my wardrobe, I have mostly warm clothing. I rarely wear skirt to work and 97% of the time I wear pants at home, going shopping, doing business etc.

Oh wow, it's silly but I never really associate Jamaica with the cold. The way we dress makes all the difference to how we feel!!

For the cold season, I do try my best to do whatever it takes to keep myself warm enough. For example, I stock up on hand and foot warmers. Amazon is my supplier. At this time of the year, I will make sure to order just enough to get through the winter season. I would put them in my boots, gloves, and pockets of my jackets or hoody to have that extra heat on me. It works well, even when it's time to play snowball with son and husband.

Please in the UK remember to apply for the warm home discount from your energy supplier, if you are on a low income ( also if you cannot work) you can get around £140 which is deducted from your bill in spring.

Hi Oye
I live in Norway, I have a son of 3 years old with SC. He goes to kindergarten. It could be really cold here.
I am wondering, which weather temperatures should he avoid during winter and summer periods?
