Here are four ways that pillows can contribute to a good night's sleep:

1. Proper head and neck support: A good pillow will provide the right amount of support for your head and neck, helping to maintain proper alignment while you sleep. This can help reduce the risk of aches and pains in the morning and improve overall comfort.

2. Pressure point relief: Memory foam or contoured pillows can help to relieve pressure on key points, such as the shoulders and lower back. This can help reduce discomfort and improve circulation while you sleep.

3. Temperature regulation: Some pillows are designed to regulate temperature, helping you stay cool and comfortable throughout the night. This can be especially helpful for people who tend to sleep hot.

4. Allergy control: Allergy-proof pillows can help to reduce the risk of allergic reactions by blocking dust, dirt, and other allergens. This can help to reduce sneezing, sniffling, and other allergy symptoms that can disrupt sleep.

In conclusion, pillows play an important role in helping you get a good night's sleep by providing proper support, relieving pressure points, regulating temperature, and controlling allergies. By choosing the right pillow for your needs, you can improve your sleep quality and wake up feeling rested and refreshed.
