Social media has a complex relationship with mental health. On the one hand, social media can provide a sense of connection and support, which can be beneficial for mental health. On the other hand, social media can also be a source of negative experiences, such as cyberbullying, FOMO (fear of missing out), and social comparison, which can have a detrimental impact on mental health.

Positive effects of social media on mental health

• Social support: Social media can provide a sense of connection and support, which can be beneficial for mental health. For example, a study by the Pew Research Center found that people who use social media to connect with friends and family are more likely to feel happy and satisfied with their lives.
• Reduced loneliness: Social media can help people to connect with others who share their interests, which can reduce loneliness. For example, a study by the University of California, San Francisco found that people who used social media to connect with others who had similar health conditions were less likely to feel lonely.
• Increased self-expression: Social media can provide a platform for people to express themselves and share their thoughts and feelings, which can be beneficial for mental health. For example, a study by the University of Texas at Austin found that people who used social media to express themselves were more likely to feel happy and satisfied with their lives.

Negative effects of social media on mental health

• Cyberbullying: Social media can be a platform for cyberbullying, which can have a detrimental impact on mental health. For example, a study by the Cyberbullying Research Center found that people who experience cyberbullying are more likely to experience depression, anxiety, and other mental health problems.
• FOMO (fear of missing out): Social media can lead to FOMO, which is the fear of missing out on what others are doing. This can lead to feelings of envy, inadequacy, and isolation, which can have a negative impact on mental health.
• Social comparison: Social media can lead to social comparison, which is the comparison of oneself to others. This can lead to feelings of inferiority, insecurity, and self-doubt, which can have a negative impact on mental health.

Overall, the research on the effects of social media on mental health is mixed. While social media can provide some benefits for mental health, it can also have some negative effects. It is important to be aware of both the positive and negative effects of social media and to use it in a way that is healthy for your mental health.

The recommended dietary allowance (RDA) for vitamin C is 90 milligrams (mg) per day for adult men and 75 mg per day for adult women. However, some people may need more vitamin C, such as those who smoke or who are exposed to high levels of pollution. The upper limit for vitamin C intake is 2,000 mg per day.

Here are some additional details about vitamin C:

• Vitamin C is a water-soluble vitamin, which means that it is not stored in the body and must be consumed regularly.
• Vitamin C is essential for the production of collagen, a protein that is found in connective tissue, bones, and skin.
• Vitamin C also helps to protect cells from damage and is involved in a number of other important bodily functions.
• Foods that are good sources of vitamin C include citrus fruits, berries, broccoli, and tomatoes.
• Taking a vitamin C supplement can help to ensure that you are getting enough of this important nutrient.

A tension headache is a common type of headache that is caused by muscle tension in the head and neck. It is often described as a dull, aching pain that is felt on both sides of the head. Tension headaches can last for hours or days, and they can be made worse by stress, fatigue, or poor posture.

There are a number of things that can help to relieve tension headaches, including:

• Over-the-counter pain relievers, such as ibuprofen or acetaminophen
• Heat or cold therapy
• Massage
• Yoga or stretching
• Relaxation techniques, such as meditation or deep breathing

If tension headaches are frequent or severe, it is important to see a doctor to rule out other possible causes.

Dengue virus disease is a serious but rarely fatal mosquito-borne illness. Symptoms include high fever, headache, muscle and joint pain, and a characteristic skin rash. Severe cases can cause fluid accumulation in the lungs and brain, which can be fatal. The World Health Organization estimates that dengue virus disease affects 390 million people each year, with 96 million symptomatic cases and 40,000 deaths.

The severity of dengue virus disease depends on the following factors:

• The strain of the virus. Some strains of dengue virus are more severe than others.
• The age of the patient. Children are more likely to develop severe dengue virus disease than adults.
• The patient's immune status. People who have been previously infected with dengue virus are more likely to develop severe disease if they are infected with a different strain of the virus.

Dengue virus disease is diagnosed based on the patient's symptoms and a blood test. There is no specific treatment for dengue virus disease. Treatment is supportive, and includes rest, fluids, and pain relievers. Severe cases may require hospitalization and treatment with intravenous fluids and oxygen.

The best way to prevent dengue virus disease is to avoid mosquito bites. This can be done by:

• Wearing long-sleeved shirts and long pants.
• Using insect repellent containing DEET or picaridin.
• Sleeping under a mosquito net.
• Eliminating standing water around homes and businesses.

Vaccines are available for some strains of dengue virus. However, these vaccines are not widely available, and they are not effective against all strains of the virus.
