Does anyone find that they tend to get overheated more than usual? I wake up hot and sweaty. During the day at times, I feel as though I am too hot and dying of thirst.

Problems regulating body temperature
Beyond heat sensitivity and Uthoff's phenomenon, MS patients may have difficulty regulating their body temperature due to impaired neural control of autonomic and endocrine functions. The part of the brain that senses core body temperature and regulates it to about 98.6° F — the preoptic anterior hypothalamus — can be affected by MS, allowing for atypical fluctuations in body temperature.
Hypothermia has been documented in small numbers of MS patients with core body temperatures ranging from to 86° F to 95° F. This can be problematic for patients when serious infections may be masked due to the absence of a typical fever response. My ‘normal’ body temperature runs closer to 95° F, so a temperature registering 99° F is more similar to 101° F in a healthy individual.
To sweat or not to sweat
When we become overheated, our bodies try to help by sweating and increasing blood flow to the skin. People with MS might not sweat as much because of impaired nerves that control normal thermoregulatory responses. However, they may experience greater increases of blood flow to the skin as compensation for impaired sweating.
Personally, I find that I sweat much more easily since developing heat sensitivity. Even a small amount of exertion will cause a slick back and damp shirt. This reinforces that everybody’s experience will be unique.
Cold sensitivity and MS
Some people living with MS may be more sensitive to cold temperatures than heat. Their symptoms get worse when the mercury falls. If this is the case, it’s important to try to keep body temperature steady, without overheating. Wearing layers of clothing, scarves, and/or wrist warmers may help, particularly if you also have Raynaud’s phenomenon.
Raynaud’s phenomenon and MS
Raynaud’s phenomenon is a condition characterized by discoloration in fingers and/or toes after exposure to changes in temperature. The tissue discoloration — which can range from purple, blue, red, or white — is typically caused by an abnormal spasm of blood vessels that reduces blood supply to the fingers or toes. Raynaud’s is commonly associated with connective tissue diseases, such as rheumatoid arthritis or scleroderma. But in an unusual case study, Raynaud’s was determined to be the presenting symptom for a person without a connective tissue disorder who was diagnosed with multiple sclerosis six months later.

The overheating! Bain of my existence, especially during the summer. Sleeping I overheat often several times/night. Use only 100% cotton sheets and if it's bad, sleep on a bath towel so when you wake up soaked, you can toss it on the floor and have a dry bed to sleep in. Keeping a fan on overhead helps a lot. Lots of water.

I definitely do. Little things make me extremely hot and sweaty. It started to get really bad last winter and I thought it was from my tecfidera but I switched to tysabri and it is still really bad. I have a cooling vest and towel plus 4 ice packs when it gets really bad
