Causes of swollen fingers in summer

In the summer, if your fingers swell, many people will feel puzzled. The weather is hot, so why does this happen? In fact, this is also a common symptom, which may be caused by both physiological and disease reasons. For example, if you consume too much salt the day before, it may cause this phenomenon. In addition, arthritis, carpal tunnel syndrome, or lymphedema are all causes of swollen fingers in the summer.

Causes of swollen fingers in summer

1. Hot summer: The heat will cause blood vessels to dilate, allowing more heat to be lost from the skin to keep body temperature from rising. At this time, some body fluid in the blood vessels will also flow to the soft tissue, causing edema.

2. Excessive salt intake: Restaurant dishes, purchased snacks, and any fried foods contain a lot of salt, which causes water to be retained in the body and causes edema.

3. Osteoarthritis: If the finger joints become swollen, this may be one of the symptoms of osteoarthritis. This disease is caused by degeneration of cartilage in the joints and is more common in middle-aged and elderly people and obese people.

4. Carpal tunnel syndrome: The nerves running from the forearm to the palm are compressed in the wrist, causing swelling and weakness in the hand. This is carpal tunnel syndrome. It is also accompanied by pain, burning, tingling and numbness.

5. Lymphedema: Lymph fluid discharges waste, bacteria and viruses from the body. When the lymph fluid cannot be fully discharged, it will cause lymphedema, leading to swelling of the limbs. At this time, the fingers, toes, and upper and lower limbs will swell.

6. Raynaud's disease: Raynaud's disease refers to paroxysmal spasms of the extremity arteries caused by vascular artery constriction, which is usually triggered by cold weather or stress. The reduced blood flow caused by the constriction of the arteries can cause the fingers to become cold and numb. Swelling occurs when the temperature rises or the pressure is removed and blood circulation returns to normal. This disease is more common in women than in men.

1. Make your fist: Before getting up every morning, make your fist in bed. The speed should not be too fast, but you should clench your fist tightly. Do it 50-100 times a day.

2. Spread your fingers: Do this movement before getting up, and practice alternately with clenching your fists, 50-100 times a day.

3. Warm water bath for both hands: After getting up, you can soak your hands in warm water for 20 minutes, keeping the water temperature at around 50℃. 4) Wrist flexion and extension exercises: Move your wrist joints after getting up. Generally, the number of times should not be too many, about 30 times is enough.
