The short answer is yes, chronic headaches can often be prevented, or at least their frequency and intensity can be significantly reduced. The following strategies focus on lifestyle changes and self-care measures which can help you manage and potentially prevent chronic headaches:

Identify Headache Triggers: Proactively documenting each headache in a journal can highlight patterns and triggers, thereby helping you to avoid these. Make sure to record important details like the time the headache started, what you were doing, and how long it lasted.

Cautious Medication Usage: Excessive consumption of headache medications, including over-the-counter ones, can increase the severity and frequency of headaches. It's advisable to consult your doctor for a safe plan to gradually reduce medication use, as abrupt discontinuation can lead to severe side effects.

Quality Sleep: For an average adult, 7-8 hours of sleep a night is essential. Try to maintain a consistent sleep schedule and seek medical advice if you have sleep disturbances, such as snoring.

Regular, Balanced Meals: Aim to eat healthy meals at consistent times daily. Be mindful of potential food and drink triggers like caffeine, and adjust your diet accordingly. Weight loss should be considered if obesity is a concern.

Regular Exercise: Engage in routine aerobic activities to improve your physical and mental well-being and reduce stress. Choose enjoyable activities like walking, swimming, or cycling, and remember to gradually increase the intensity to prevent injury.

Stress Management: Stress can often trigger chronic headaches. Incorporate stress-reducing techniques into your routine such as yoga, tai chi, and meditation. Moreover, staying organized, planning ahead, and maintaining a positive outlook can greatly help in managing stress.

Moderate Caffeine Intake: While caffeine is included in many headache medications due to its pain-alleviating properties, it can also exacerbate headaches. Try to reduce or completely remove caffeine from your diet.
